BACKGROUND OF THE INVENTION Dibenzylidene sorbitol (also called dibenzaldehyde monosorbitol acetal, or dibenzyl monosorbitol acetal or dibenzylidene monosorbitol acetal) and derivatives thereof such as those which are substituted on one or both of the aromatic rings with a fluorine or methoxy group and those which have the sorbitol portion replaced with other reduced sugars such as xylitol or ribitol as described in U. S. Patent 5,609,855 assigned to Procter & Gamble (collectively referred to as dibenzylidene sorbitol or"DBS") may be used in various food and cosmetic applications. For cosmetic uses the more interesting ones are those focused on obtaining a translucent or clear product. While dibenzylidene sorbitol is stable in alkaline or neutral media, such compounds are not stable in acicic media. In an acidic environment, such as in the presence of acidic antiperspirant materials, and when in the presence of even small amounts of water, the

dibenzylidene sorbitol deteriorates and breaks down. Also. the use of DBS sometimes causes problems in the aesthetics of cosmetic products or problems with structural properties. Accordingly, there is a need to find a way to form products containing DBS which are stable and which have acceptable aesthetics.

The use of DBS requires the use of polyhydric alcohols such as propylene glycol as a solvent if a clear, transparent product is desired. The high propylene glycol content, when combined with aluminum salts which are included in antiperspirant compositions for wetness control, contribute to undesirable tackiness or a sticky feel for these products when applied to the axilla rezion of the body. DBS clear antiperspirant sticks were first formulated in the late 1970's. There have been continued technical efforts to reduce the negative sensory attributes. Some of these efforts have focused on alternative solvents to replace a portion of the propylene glycol with organic esters known in the art as emollients. This creates a further problem since many of these emollients are either unsafe for personal care products or do not achieve acceptable aesthetics.

For formulating personal care products the incorporation of silicone fluids is known in the art. Silicone tluids such as cyclosiloxanes (for example, DOW CORNING 244 and 245 Fluids) are used in some major commercial products.

Silicone fluids are used because of their low tackiness, superior glide and skin-feel properties. However, silicone fluids are difficult to introduce into DBS based cosmetic stick products such as antiperspirants because they are not good solvents for DBS and they are not readily compatible with propylene glycol and many organic esters or emollients.

Some of the efforts on each of these fronts are described as follows. For example, some efforts have focused on the stability of DBS. United Kingdom Patent GB 2 280 111 assigned to Union Camp Corporation, describes a gel stick composition comprising a dihydric alcohol as a primary solvent, a co-solvent such as low molecular weight polyethylene glycol, water and/or glycerine, a buffering agent and DBS as a gelling agent.

There still remains a need, however, to develop translucent, preferably clear, cosmetic products which provide reduced tack in a DBS product. Thus, it is an object of the present invention to provide a cosmetic composition which comprises DBS and which provides reduced tack when applied to the skin. It is a further object of the

invention to provide cosmetic compositions containing DBS which can be used to form deodorant and/or antiperspirants which are translucent to clear. It is yet another object of the invention to provide cosmetic compositions which enhance the compatibility of DBS in propylene glycol systems which also contain silicone fluides. These and other objects of the invention will be apparent from the following description of the invention.

Summarv of the Invention The invention comprises a cosmetic composition which is a translucent to clear stick having low tack. The cosmetic sticks are formed by combining the components described below to form a two phase system. These components, in weight percent based on the total weight of the composition, are: (a) from weight percent of a silicone fluid phase (as the first or internal phase) which comprises at least one hydroxy functionalized silicone fluid, at least one stabilizing agent and, optionally at least one additional silicone material: (b) from 40-95 weight percent of a gellant/solvent phase (as the second or external phase) which comprises a mixture of dibenzylidene sorbitol and at least one solvent such as a polyhydric alcohol (for example, propylene glycol); (c) an effective amount of at least one active ingredient; and (d) optionally one or more members selected from the group consisting of emollients, fragrances, coloring agents, etc., wherein the materials listed in parts (c) and (d) may become part of either of the phases described in part (a) or part (b).

Brief Description of the Drawinvs

Figure 1 shows data from a Forearm Flex Test done with an antiperspirant sample from Example 5 formulated with DBS and silanol (line with circles) and a commercial deodorant product formulated with DBS but without silanol (line with squares). The tack profile shows that the formulation of Example 5 is 5-10% less tacky than a commercial deodorant stick which contains no antiperspirant. This is significant because the addition of an antiperspirant salt creates increased problems with tack. The ability of an antiperspirant formulation to perform as well or better than a deodorant stick which does not contain an antiperspirant salt is a significant development.

Figure 2 shows data from a Forearm Flex Test done with an antiperspirant sample from Example 5 formulated with DBS and silanol (line with circles) as compared to a clear, commercially available antiperspirant stick formulated with DBS but without silanol (line with squares). The tack profile of the formulation of Example 5 is significantly less tacky (on the order of 65-70% less) than the commercial product. This result demonstrates the superiority of the present invention.

Detailed Description of the Invention The compositions of this invention are made by combining the components described above in a two phase system to form a stick cosmetic composition. The first phase is the silicone fluid phase and comprises at least one hydroxy functionalized silicone fluid and at least one stabilizing agent. Compounds of Formula I are described as follows and can be used with or without additional silicone fluids. Suitable functionalized silicone fluids are hydroxy functional fluids with the general structure of Formula I:

Formula I where each of R', R2, and R, may be alike or different and are each independently selected from the group consisting of Cl-C4 straight chain alkyls (especially methyl): a is a number in the range of 0-10, with particular values of"a"being 0 for linear compounds and 1-10 for branched compounds (for example 6-8) ; b is a number in the range of 0-10,000, with particular values of"b"being 4-6000 : c is a number in the range of 1-10, with particular values of"c"being 2 when the compound is linear and at least 3 when there is branching : provided that a and b cannot both equal zero at the same time. It is to be recognized that a, b, and c are average values (including whole numbers and fractions) and mixtures of compounds with various values for a, b, c, R', R2, and R'may also be used.

Examples of compounds of Formula I include: (a) linear polydimethylsiloxanediols where a = 0, b = 4-6. 000 (for example, an average value of 4,40 or 6,000) ; (b) linear polydimethylsiloxanediols where a = 0, b 4-1. (X) O and c = 2: (c) multifunctional branched siloxanes where a = 1 2. b = 0-1,000, and c = 3- 4; (d) linear polydimethylsiloxanediols where a = 0, b = 4U and c=2 ; (e) multifunctional branched siloxanes where a = 1, b = 16, and c = 3; (t) multifunctional branched siloxanes where a = 1-2, b = 1 ()-1,000, and c = 3- 4 ;

(g) mixtures of the particular compounds described in parts (a)- (l) for example, mixtures wherein the average structure of the mixture is described by a = 0.1, b = 4- 6000, and c = 2-7 : and (h) two component mixtures of the particular compounds described in parts (a)- (t) wherein one component is 0.1-99. 9% of the composition and the other component is the remainder to 100%.

For each of the groups listed as (a)- (1) above, particular examples of the compounds are when each of the R groups is selected to be methyl. Also, for any of the groups (a)- (g), additional silicone fluids such as dimethicone may be added, for example in amounts of 0.1- 90% functionalized silicone and 10- 99. 9% silicone fluid or fluids.

One particular group of compounds of Formula I are linear silanols of Formula IA, especially when b = 40: Formula IA Some of the compounds of Formula I may be purchased commercially. For methods of making other compounds of this invention descriptions of suitable methods may be found in the literature for example, U. S. Patent to Dow Corning; U. S.

Patent 3,441, 537 to Staffer Chemical Company: and Noll, W., Chemistry and Technology of Silicones, (Academic Press, Inc. Orlando, Florida 1968) especially at pages 190-196 and 239-245, all of which are incorporated herein by reference.

While the hydroxy functionalized silicones described above are preferably selected to have a viscosity that does not require additional silicone materials (for example, having a viscosity in the range of up to 60, 000 centistoke (cst), it is possible to

use compositions which are a blend of hydroxy functionalized silicones having higher viscosities such as those having a high viscosity (>500. 000 centistoke) dimethiconol in dimethicone where the dimethicone has a viscosity in the range of 5-350 centistoke (for example, DOW CORNING 1403 Fluid).

For high viscosity functionalized silicones (for example, the silicone gums), and for the purpose of facilitating its handling and processing, these materials are generally provided as blends with another volatile or non-volatile low viscosity silicone such as CYCLOMETHICONE, or a non-volatile linear silicone fluid having a viscosity of about 5 to 350 centistoke. Such dimethyl silicone polymers terminated with hydroxyl groups have been assigned the INCI name"DIMETHICONOL"by The Cosmetics, Toiletries and Fragrance Association, Inc., Washington, D. C. (CTFA). Blends of such silicone gums with a volatile low viscosity cyclic silicone have been assigned the INCI name "CYCLOMETHICONE (and) DIMETHICONOL"by the CTFA. Other blends of such silicone gums with a non-volatile low viscosity linear silicone have been assigned the INCI name"DIMETHICONE (and) DIMETHICONOL"by the CTFA. The DIMETHICONOL content of such blends is typically in the range of about 12 to 14 percent by weight, and the blend viscosity may range from 500 to about 20, 000 centistoke, generally in the range of about 4,000 to 5,000 centistoke.

Other volatile low viscosity methylsilicone fluids are described in U. S. Patent Number 5,302,382 to Kasprzak, incorporated by reference herein. Examples of methylsilicone fluids having viscosities of less than about one hundred centistoke measured at twenty-five degrees Centigrade, preferably less than about five centistoke

and also methylsilicone fluids having a viscosity in the range of 1-350 centistoke are disclosed.

One group of methylsilicone fluids is volatile low viscosity methylsilicone fluid containing dimethylsiloxane units and, optionally, trimethylsiloxane units.

Representative compounds are cyclopolysiloxanes of the formula and linear short chain siloxane compounds of the formula (CH3)3SiO[(CH3)2SiO]ySi(CH3)3, in which x is an integer having a value of from three to ten, (especially 4-6) and y is an integer having a value of from zero to about four. The cyclopolysiloxanes have been assigned the INCI name"CYCLOMETHICONE"by The Cosmetics. Toiletries and Fragrance Association, Inc.. Washington, D. C. (CTFA).

The silicone fluid phase can also, optionally, include other silicone materials even when the purpose is for reasons other than viscosity modification. Particular silicone fluids are selected so that a stable silicone/glycol suspension is formed when the two phases are combined and mixed. Such materials can include, for example, other silicone fluids such as polydimethylsiloxanes. polydiethylsiloxanes. and polymethylethylsiloxanes, having a viscosity in excess of 350 centistoke and up to 2.500.000 centistoke, preferably, 350-10, 000 centistoke. Further examples include cetyl dimethicone copolyol, dimethicone copolyol (such as DOW CORNINGO 2501, Q2-5220 and 5324 products); a mixture of cyclomethicone and dimethiconol (such as DOW CORNINGO 1401 product) ; a mixture of dimethicone and dimethiconol (such as DOW CORNINGO 1403 product) ; cetyl dimethicone (DOW CORNING# 2502 product) ; and stearyl dimethicone (DOW CORNING (D 2503 product).

A stabilizing agent is also included in the silicone phase. This stabilizing agent may be selected from several types ot groups. One such group is silicone polyether surfactants having a hydrophilic/lipophilic balance ("HLB"value) compatible with the solvent and the silicone phase particularly to form a stick composition. For example, if propylene glycol is used as the solvent a polyether surfactant with an HLB value of I-10 is preferred (for example, DOW CORNING 3225 C Formulation Aid (HLB = 1.7) DOW CORNINGO 190 Surfactant (HLB = 5)). If tri-and/or tetrapropylene glycol is used as the solvent a polyether surfactant with an HLB value in the range of 5-10 is preferred. For example, a cosmetic composition may be formed wherein the stabilizing agent is a member of the group consisting of silicone polyether surfactants having a hydrophilic/lipophilic in the range of I-10, and the solvent comprises greater than 50% by weight of propylene glycol, dipropylene glycol, tripropylene glycol or tetrapropylene glycol.

A particular siloxane polyether has the following Formula II: Formula II wherein Ra is an alkyl group of one to six carbon atoms: Rb is the radical-C"H2"l-; Rc is a terminating radical which can be hydrogen, an alkyl group of one to six carbon atoms, an ester group such as acyl, or an aryl group such as phenyl ; m has a value of two to eight; p and s have values such that the oxyalkylene segment- (C2H40)p- (C3H60).s- has a molecular weight in the range of 200 to 5,000 : the segment preferably having fifty to one hundred mole percent of oxyethylene units- (C, H40),,- and one to fifty mole percent of oxypropylene units-(C3H60) 5-;(C3H60) 5-; x has a value of 8 to 4Q0; and y has a value of 2 to 40.

Preferably R'is a methyl group. R'is H: m is preferably three or four whereby the group Rb is most preferably the radical- (CH) 3- ; and the values of p and s are such as to <BR> <BR> provide a molecular weight of the oxyalkylene segment-(C2H40) p-(C3H60) s-of between about 1,000 to 3.000. Most preferably p and s should each have a value of about 18 to 28.

A second siloxane polyether has the Formula III: Formula III wherein R"is an alkyl group of one to six carbon atoms: Rb is the radical-Cn, H2n-: R'is a terminating radical which can be hydrogen, an alkyl group of one to six carbon atoms, an ester group such as acyl, or an aryl group such as phenyl: m has a value of two to eight; p has a value of 6 to 16: x has a value of 6 to 100 : and y has a value of I to 20.

It should be understood that in both Formulas II and III shown above, that the siloxane-oxyalkylene copolymers of the present invention may, in alternate embodiments, take the form of endblocked polyethers ir. which the linking group Rb. the oxyalkylene segments, and the terminating radical Rc occupy positions bonded to the ends of the siloxane chain, rather than being bonded to a silicon atom in the siloxane chain. Thus, one or more of the Ra substituents which are attached to the two terminal silicon atoms at the end of the siloxane chain can be substituted with the segment-Rb-O- (C2H40) p- (C3H60),-RC or with the segment -Rb-O-(C2H4O)p-Rc. In some instances, it may be desirable to provide the segment -R6-O-(C2H4O)p-(C3H6O)s-Rc or the segment- Rb-O- (C2H4O p-RC at locations which are in the siloxane chain as well as at locations at one or both of the siloxane chain ends.

Mixtures of silicone polyethers can also be used. Such mixtures include components which themselves met the HLB criteria described above or which, in combination, meet the HLB criteria described above.

In one particular embodiment the silicone fluid phase comprises at least a portion of a silicone polyether surfactant to stabilize the cosmetic composition when it contains an antiperspirant active material. In antiperspirant compositions the polyether component is preferably used in an amount of 1.0-25. 0 weight percent. These silicone polyethers can be added to the silicone fluid phase before the mixing of the first and second phases or the polyether can be added to the combined mixture at the end of the process during the cool down cycle. Examples of suitable silicone polyethers include DOW CORNINGO 190 Surfactant (HLB of 5.6), DOW CORNING 193 Surfactant (HLB of 12.-12.45), DOW CORNING 2501 Cosmetic Wax (HLB of 19.0), DOW CORNINGO 5200 (HLB of 6.83), DOW CORNINGO 5324 (HLB of5.0), DOW CORNINGO 3225C Formulation Aid. and DOW CORNING 5220 (HLB of 71.7).

The stabilizing agent can also be a high refractive index (greater than 1.4325) modifier, for example a member selected from the group consisting of isopropyl myristate, isopropyl palmitate, mineral oil, oleyl alcohol sorbitol, glycol, octyl salicylate, octylmethoxycinnamate; phenyl siloxanes of Formula IV: Formula IV where R5, R6 and R7 are each independently selected from methyl and phenyl, and p is a <BR> <BR> <BR> number in the range of 0-10 (for example , trimethylphenylsiloxanes such as DOW CORNING (D 556 Fluid; and polydiphenylsiloxanes, for example, tetramethyl

letraphenyl trisiloxane such as DOW CORNING 704 Fluid and trimethyl pentaphenyl trisiloxane such as DOW CORNINGO 705 Fluid).

Another stabilizing agent is a member selected from the group consisting of alkyl <BR> <BR> galactomannose (for example, N-Hance AG 50 and N-HanceX AG 200 from Hercules Inc., Aqualon Division, Wilmington, Delaware).

The second phase is the gellant/solvent phase. This phase is made by combining: (a) weight percent DBS (based on the total weight percent of the composition); (b) 0. 1 - 1.0 weight percent of a co-gellant or structural integrity enhancer selected from the group consisting of hydroxypropyl cellulose, alkyl ester thickeners (for example, PEG-150 pentaerythrityl tetrastearate called CROTHIX from Croda Chemicals, Parsippany, New Jersey), fumed silica (for example, Cab-O-SilO, from Cabot, Flemington, New Jersey ; Aerosil) from DeGussa, Ridgefield Park, New Jersey), waxes such as alkyl methylsiloxanes (for example. AMS-30 (C30-C45 alkyl methicone available from DOW CORNING CORPORATION, Midland, Michigan), selected guars such as an hydroxy C3 - C4 alkyl guar having a level of hydroxyalkylation of 0.4-1.5 molar substitution as described in copending case filed on the same date herewith and incorporated herein by reference, entitled"Clear Antiperspirant Stick With Dibenzylidene Sorbitol and Guar and Process of Making Same'for which a serial number has not yet been received and referenced herein as Attorney Docket Number 5947. A particularly preferred combination is 0.05%-1. U% CROTHIX in combination with 1.0%-5.0% PPG-5 Ceteth-20 and a suitable base such as 0.1%-1. 0%ofguanidine

carbonate. Hydroxypropyl cellulose may be used in an amount of 0.2%-1. U7o by weight based on the total weight of the composition.

(c) 0.1-80 weight percent of a solvent selected from the group consisting of polyhydric alcohols for example, propylene glycol, dipropylene glycol, tripropylene glycol and tetrapropylene glycol, PPG-10 butane diol, 1.3-butane diol, PEG-6, PPG- 425. including up to 50 percent of other solvents selected from propylene carbonate, diisopropyl sebacate, methyl pyrrolidone, and ethyl alcohol.

The third component used to make the compositions of the invention is at least one cosmetically active ingredient selected, for example, from the group consisting of antiperspirant salts, sunscreens, bacteriostats, fragrances and insect repellents.

Various antiperspirant active materials that can be utilized according to the present invention include conventional aluminum and aluminum/zirconium salts, as well as aluminum/zirconium salts complexed with a neutral amino acid such as glycine, as known in the art. See each of EP No. 512,770 A1 and PCT No. W092/19221, the contents of each of which are incorporated herein by reference in their entirety, for disclosure of antiperspirant active materials. The antiperspirant active materials disclosed therein, including the acidic antiperspirant materials. can be incorporated in the compositions of the present invention. Suitable materials include (but are not limited to) aluminum chlorohydroxide, aluminum chloride, aluminum sesquichlorohydroxide, zirconyl hydroxychloride, and aluminum chlorohydrol-propylene glycol complex. These include, by way of example (and not of a limiting nature). aluminum chlorohydrate, aluminum chloride, aluminum sesquichlorohydrate, zirconyl hydroxychloride, aluminum- zirconium glycine complex (for example, aluminum zirconium trichlorohydrex gly,

aluminum zirconium pentachlorohydrex gly. aluminum zirconium tetrachlorohydrex gly and aluminum zirconium octochlorohydrex gly), aluminum chlorohydrex PG, aluminum chlorohydrex PEG, aluminum dichlorohydrex PG. and aluminum dichlorohydrex PEG.

The aluminum-containing materials can be commonly referred to as antiperspirant active aluminum salts. Generally, the foregoing metal antiperspirant active materials are antiperspirant active metal salts. In the embodiments which are antiperspirant compositions according to the present invention, such compositions need not include aluminum-containing metal salts, and can include other antiperspirant active materials, including other antiperspirant active metal salts. Generally. Category I active antiperspirant ingredients listed in the Food and Drug Administration's Monograph on antiperspirant drugs for over-the-counter human use can be used. In addition, any new drug, not listed in the Monograph, such as aluminum nitratohydrate and its combination with zirconyl hydroxychlorides and nitrates, or aluminum-stannous chlorohydrates. can be incorporated as an antiperspirant active ingredient in antiperspirant compositions according to the present invention. Preferred antiperspirant actives that can be incorporated in the compositions of the present invention include the enhanced efficacy aluminum salts and the enhanced efficacy zirconium/aluminum salt-glycine materials, having enhanced efficacy due to improved molecular distribution, known in the art and discussed, for example, in PCT No. W092/19221, the contents of which are incorporated by reference in their entirety herein.

The amount of antiperspirant active material incorporated in the stick composition of the present invention is preferably, an antiperspirant effective amount; that is, an amount to reduce the flow of perspiration from the location (for example,

axillary region of a human) to which the antiperspirant is applied. For deodorant products a level of from 0.5-20%, more particularly 0.5-5.0% by weight based on the entire weight of the composition is used. For an antiperspirant product an amount of 5.0-25%, particularly 5-20%, even more particularly 7-15%, and especially 7-12% by weight based on the total weight of the composition may be used. The amount of antiperspirant material utilized is dependent on the efficacy of the specific antiperspirant material, as well as a maximum amount which avoids a reduction in clarity of the final product.

For embodiments of the invention which contain an antiperspirant (either at a level denominated"deodorant"or at a level denominated"antiperspirant") it is preferred that a stabilizing agent also be included Examples of suitable stabilizing agents include cosmetically acceptable alkali metal salts, bases, amines and other nitrogen containing compounds, particularly guanidine carbonate (described in U. S. Patent Number Examples of suitable sunscreens include octyl methoxycinnamate, aminobenzoic acid, octyl salicylate, oxybenzole and cosmetically acceptable ultraviolet light absorbers for example as listed in the CTFA Cosmetic Ingredient Handbook at page 98.

Suitable insect repelling agents include N, N-diethyl-m-toluamide ("DEET") and citronella.

Known bacteriostats include bacteriostatic quaternary ammonium compounds such as 2-amino-2-methyl-I-propanol (AMP), cetyl-trimethylammonium bromide, cetyl pyridinium chloride, 2,4, 4'-trichloro-2'-hydroxydiphenylether (Triclosan), N-(4- chlorophenyl)-N'- (3,4-dichlorophenyl) urea (Triclocarban) and various zinc salts (for example, zinc ricinoleate). The bacteriostat can, illustratively, be included in the

composition in an amount of 0.1-1.0% by weight, of the total weight of the composition. Triclosan, can illustratively be included in an amount of from 0.1 % to about 0.5% by weight, of the total weight of the composition.

The fourth component used to make the compositions of the invention is the remainder and portion comprising one or more of the following optional ingredients: emollients, fragrances, coloring agents and ingredients having a lower refractive index than 1.4325 such as water, ethanol, wherein the materials listed in this fourth component may become part of either the silicone phase or the gellant/solvent phase.

Emollients may be selected from the group consisting of emollient oils such as a liquid mixture of hydrocarbons which are liquids at ambient temperatures (such as petroleum distillates and light mineral oils), mineral oil, peanut oil, sesame oil, avocado oil, coconut oil, cocoa butter, almond oil, safflower oil, corn oil, cotton seed oil, castor oil, olive oil, jojoba oil, paraffin oil, cod liver oil, palm oil, soybean oil, wheat germ oil, linseed oil, and sunflower seed oil; fatty acid esters such as isopropyl myristate, isopropyl palmitate, isopropyl stearate. isopropyl isostearate, butyl stearate, octyl stearate. hexyl laurate, cetyl stearate, diisopropyl adipate, isodecyl oleate, diisopropyl sebacate, isostearyl lactate and lauryl lactate : fatty acids such as lauric, myristic, palmitic, stearic, oleic, linoleic, and behenic, acid ; fatty alcohols such as lauryl, myristyl, cetyl, isocetyl, stearyl, isostearyl, oleyl, ricinoleyl, erucyl, and 2-octyl dodecanol, alcohols; lanolin and its derivatives such as lanolin, lanolin oil, lanolin wax, lanolin alcohols, lanolin fatty acids, isopropyl lanolate. ethoxylated lanolin, and acetylated lanolin alcohols such as ACETULANO, a trademark and product of Amerchol Corporation, Edison, New Jersey ; and hydrocarbons such as petrolatum and squalene.

Any of the components such as the liquid esters and silicone fluids, materials s characterized by their refractive indices, especially the silicone fluids, described above can be selected to enhance the clarity and transmission of light as evaluated by measurements of transmittance of light. One such device is a turbidimeter such as Model 965-10A Digital Direct-Reading Turbidimeter from Orbeco Analytical Systems, Inc., Farmingdale. New York, with the use of acceptable accepted test protocols such as ASTM D 5180-93 entitled"Standard Test Method for Quantitative Test for Turbidity in Clear Liquids ; ASTM D 1889-94 entitled"Standard Test Method for Turbidity of Water" : and selected methods from Standard Methods for the Examination of Water and Wastewater (American Public Health Association Washington D. C., 1995): No. 2130 "Turbidity". Values in the range of 30-950 nephelometric turbidity units (NTU), preferably below 800 NTU and more preferably below200 NTU, and particularly below 100 NTU are preferred.

A desired feature of the present invention is that a clear, or transparent, cosmetic composition, (for example, a clear or transparent deodorant or antiperspirant composition) can be provided. The term clear or transparent according to the present invention is intended to connote its usual dictionary definition: thus, a clear, for example, stick or gel antiperspirant composition of the present invention allows ready viewing of objects behind it. By contrast, a translucent composition, although allowing light to pass through, causes the light to be scattered so that it will be impossible to see clearly objects behind the translucent composition. An opaque composition does not allow light to pass therethrough. Within the context of the present invention, a gel or stick is deemed to be transparent or clear if the maximum transmittance of light of any

wavelength in the range 4 () ()-8 () () nm through a sample 1 cm thick is at least 35%, preferably at least 50%. The gel or stick is deemed translucent if the maximum transmittance of such light through the sample is between 2% and less than 35%. A gel or stick is deemed opaque if the maximum transmittance of light is less than 2%. The transmittance can be measured by placing a sample of the aforementioned thickness into a light beam of a spectrophotometer whose working range includes the visible spectrum, such as a Bausch & Lomb Spectronic 88 Spectrophotometer. As to this definition of clear, see European Patent Application Publication No. 291, 334 A2. Thus, according to the present invention, there are differences between transparent (clear), translucent and opaque compositions.

Particular embodiments of the invention which may be used are antiperspirant sticks having the following formulations which are at least translucent.

Because of the chemical instability of DBS in the presence of water in low pH media, it is preferred that antiperspirant formulations be essentially anhydrous and contain sufficient buffering agents to keep the pH in the range of 4. ()-5. 0. Deodorants and other cosmetic preparations which are at a higher pH do not require this restriction.

Particular compositions according to the present invention include those made by combining in percent by weight based on the total weight of the composition: (a) 6.0-35% of the silicone fluid phase : (b) 25-70% of a polyhydric alcohol selected from the group consisting of propylene glycol. dipropylene glycol tripropylene glycol, tetrapropylene glycol and mixtures thereof; (c) 1.5-2.5% dibenzylidene sorbitol : and

(d) 5-25% antiperspirant active.

Throughout the present specification. where compositions are described as including or comprising specific components or materials, or where methods are described as including or comprising specific steps, it is contemplated by the inventors that the compositions of the present invention also consist essentially of, or consist of, the recited components or materials, and also consist essentially of, or consist of, the recited steps. Accordingly, throughout the present disclosure any described composition of the present invention can consist essentially of, or consist of, the recited components or materials, and any described method of the present invention can consist essentially of, or consist of, the recited steps.

As noted above, the compositions of the present invention have less tack than conventional cosmetic sticks. This is especially true of antiperspirant sticks made according to the invention. Tack can be evaluated by various techniques including the Forearm Flex Test.

Forearm Flex Test-In this test the administrator first over-wraps the test products to hide their identity from the panelists and then gives each sample a code number to hide their identity from the statistician who will analyze the data. These precautions are done to avoid bias of the panelists and the test evaluators. Next, one of two products is applied to one arm at the crease of the elbow and the second product is applied to the same area of the other arm. The two products are applied in a similar manner. Product application is done by either counting the number of strokes or by weighing the products to be tested before and after. Products are applied in random fashion to eliminate left-handed or right-handed biases. The ambient room temperature

and humidity are recorded. Using the same control product for every test allows for a comparison between test results for various experimental formulations. The panelists evaluate the tested products for several aesthetic attributes including, but not limited to, wetness, oily/greasy feel, glide, and, most importantly, tackiness/stickiness. The panelists evaluate initial tackiness immediately after a product application and repeatedly at predetermined time intervals for an overall time of 90 minutes. The assessment of tack is made by flexing the arm and judging the adherent forces between contacted skin surfaces. A scale of 1 to 7 is used by each panelist with 1 = Not Tacky and 7 = Extremely Tacky. The collected data is used to generate a"Tack Profile"which is a plot of Tackiness versus Time. Data analysis using a statistical software package called JMP from SAS Institute (Cary. North Carolina) permits identification of products which are significantly different from the Control sample. The Control is selected to be a competitive benchmark currently in the marketplace which represents what is believed to be the best commercially available standard. In addition to an analysis of product performance at specific time periods, the performance of the tested sample throughout the 90 minute test period can be made by calculating the area under each curve in the Tack Profile graph and comparing the differences.

The following Examples are given as illustrative of the invention but other modifications may be made by those skilled in the art which are within the spirit and scope of the invention. Unless otherwise noted all amounts are in weight percents. All chemical symbols and scientific abbreviations have their usual and customary meanings and all temperatures are in degrees C. The aluminum zirconium tetrachlorhydrex glycine complex listed in the following examples is a solution comprising about 28% by weight

actives in a mixture of polyhydric alcohols (such as WestchlorX ZR 35B from Westwood Chemical. Middletown. New York). In addition about (). 75% + 0.25 guanidine carbonate was added to the actives solution (although the amount may be varied from 0.5%- 1. 0% guanidine carbonate). It will also be appreciated by those skilled in the art that preheating of ingredients was done as needed to ensure good mixing.

Example B General Method B Gel Phase I) Charge the formula amount of Propylene Glycol (PG) to the main mixing vessel and begin agitation sufficient enough to create a vortex.

2) Slowly sprinkle-in the Hydroxypropyl Cellulose (HPC) or Hydroxypropyl Guar (HPG) into the PG.

3) Once the HPC or HPG is homogeneously dispersed begin heating to 60 degrees C to facilitate complete hydration with continued agitation.

Example C Alternative Order of Addition This method can be used when additional solvents partially replace propylene glycol or when the DBS level drops below 2 weight percent. Either of these occurrences lowers the dissolution temperature. Examples of such solvents with a lower DBS dissolution temperature include propylene carbonate, polyhydric alcohols (for example, dipropylene glycol. dipropylene glycol, tripropylene glycol, tetrapropylene glycol), PEG-6, carbonate, N-pyrrolidone and mixtures of such solvents.

Gel Phase 1) Charge the formula amount of Propylene Glycol (PG) to the main mixing vessel and begin agitation sufficient enough to create a vortex.

A sample made according to the method of Example 5 was evaluated using the Forearm Flex Test described above. This example uses a silicone surfactant and cyclomethicone. The results are shown in Figure 1 and explained above.

Example 6 The method described in Example A was repeated except that a silicone polyether surfactant having a higher solids content was used instead of the dimethicone copolyol (and) cylcomethicone (DOW CORNINGO 3225C Formulation Aid used in Examples 1-4). Such a material could also be made by taking the DC 3225C material and removing enough cyclomethicone to obtain a solids content of the surfactant of about 50% by weight of the surfactant. The branched silanol (hydroxy functional branched siloxane) used was a blend of linear and branched silanols wherein"a"had an average value of 0.1,"b"had an average value of 16 and"c"had an average value of 3.

The compositions were evaluated as described in Example 8. The composition of Example 9 was judged to be stable with good structure. The formulation of Example 10 was judged to have poor stability after 24 hours and the silicone phase separated.

Note that Example 10 with propylene glycol used a surfactant with an HLB value of 12.2 which is greater than 10.

Example 11 The method described in Example 8 was repeated with the following amounts of ingredients: 25.8% silanol 3.0% dimethicone copolyol (and) cylcomethicone (DOW CORNING O 3225C Formulation Aid) 10.0% phenyltrimethicone (DOW CORNING (Z 556 Fluid) 29% propylene glycol 2.0% DBS

Example 12 The silanol and polyether surfactant described in Example 6 were used with the method described in Example A for compositions formulated with the following amounts of ingredients: 10.0%silanol 0.30% polyether surfactant 15.0% phenyltrimethicone (DOW CORNING# 556 Fluid) 41.7% propylene glycol 2.0% DBS 1.0% hvdroxypropyl cellulose 30. 0% Al-Zr tetrachlorhydrex gly 1 () 0% The composition was evaluated using the scale described in Example 11 and rated as"9" indicating a clear composition.

Example 13 Propylene glycol (4 (). 4%) and hydroxypropyl cellulose (1.0% KLUCEL) is charged to a main mixing vessel and heat is used to raise the temperature to about 100 degrees C. DBS (2.0%) is added and with stirring and heating until the DBS is melted into the solvent mixture (temperature is at 130-135 degrees C). Guanidine carbonate (0.3%) is added with cooling and stirring as the temperature is lowered to about 105- 110 degrees C. In a separate container PPG-5-Ceteth-20 (5.0% PROCETYL AWS, from Croda) is added with stirring to the actives phase (30. 0% of Al-Zr tetrachlorhydrex gly). A silicone phase is made in a separate vessel hv combining silanol (1 0. 0% of a silanol described in Example 6), a polyether surfactant of the type as described in Example 6 (0.30%), and phenyltrimethicone (10. 0% of DOW CORNING 556 Fluid) with heating and stirring to about 105 degrees C. The mixture with the actives is added at 105 degrees C to the main vessel. Then the silicone phase is added. An emulsion is made with the combination of the contents of the two vessels with stirring and cooling to about 100 degrees C. Further cooling is allowed and when the mixture is at a temperature of about 85-90 degrees C. PEG-15 () pentaervthritvl tetrastearate (1. () 676 CROTHIX) is added with stirring until melted. The mixture is allowed to cool as needed to a temperature in the range of 85-90 degrees C and then may be poured into the final containers for setting. A composition made by such a process was evaluated by the scale described in Example 11. It was soft but the combination helped to reduce droplet size of the internal phase, thus improving clarity.

Examples 14-18 The method of Example C was used with the amounts and types of ingredients listed in Table 5. The amounts given are in weight percents based on the total weight of the composition as 100 percent.
