COSMETIC COMPOSITIONS CONTAINING SILICONE RESIN EMULSIONS

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of United States Provisional Patent Application No. 61/789,635 filed March 15, 2013.

BACKGROUND OF THE INVENTION

[0002] Silicone resins and pressure sensitive adhesives (PSAs) are used in many industrial applications such as in the coatings industry. Preparation of aqueous mechanical emulsions of silicone resins or PSAs is difficult due to the handling of such highly molecular weight and/or solid materials. Often, the silicone resin or PSA is dissolved in an organic aromatic solvent, or require specialized surfactants containing aromatic solvents. The presence of such solvents presents manufacturing challenges and also precludes their use in many personal, cosmetic, or healthcare applications. Silicone resins or PSAs can be emulsified using specialized equipment such as a twin screw extruder (TSE). However, the costs for such equipment are relatively high, both from a capital and an operational standpoint.

[0003] Recently, the present inventors have disclosed in PCT/US13/24761 that mechanical emulsions of silicone resins or PSAs may be readily prepared in simple equipment using a specific class of certain nonionic surfactants, namely

poly(oxyethylene)-poly(oxypropylene)-poly(oxyethylene) block copolymers.

BRIEF SUMMARY OF THE INVENTION

[0004] The present inventors have found the silicone resin emulsions disclosed in PCT/US13/24761 are useful to prepare cosmetic compositions. Thus, the present disclosure provides cosmetic compositions comprising:

i) a silicone resin emulsion comprising;

A) 0.5 wt % to 95 wt % of a silicone resin or pressure sensitive adhesive (PSA),

B) 0.1 to 90 wt % of a ethylene oxide/propylene oxide block copolymer, and sufficient amount of water to sum to 100 weight percent, ϋ) at least one cosmetic ingredient (C),

iii) optionally in a cosmetically acceptable medium. DETAILED DESCRIPTION OF THE INVENTION

[0005] The silicone resin emulsion useful in the present cosmetic compositions comprise;

A) 0.5 wt % to 95 wt % of a silicone resin or pressure sensitive adhesive (PSA),

B) 0.1 to 90 wt % of a ethylene oxide/propylene oxide block copolymer, and sufficient amount of water to sum to 100 weight percent.

A) The Silicone Resin or Pressure Sensitive Adhesive (PSA)

[0006] Component A) may be either a silicone resin or PSA. As used herein, "silicone resin" refers to any organopolysiloxane containing at least one (RS1O3/2), or (S1O4/2) siloxy unit. As used herein in its broadest sense, a silicone PSA refers to the reaction products resulting from reacting a hydroxyl endblocked "linear" organopolysiloxane with a "resin" organopolysiloxane, wherein the resin organopolysiloxane contains at least one (RS1O3/2), or (S1O4/2) siloxy unit.

[0007] Organopolysiloxanes are polymers containing siloxy units independently selected from (R3S1O-1/2), (R2Si02/2) _> (RS1O3/2), or (S1O4/2) siloxy units, where R may be any organic group. These siloxy units are commonly referred to as M, D, T, and Q units respectively. These siloxy units can be combined in various manners to form cyclic, linear, or branched structures. The chemical and physical properties of the resulting polymeric structures vary depending on the number and type of siloxy units in the organopolysiloxane. "Linear" organopolysiloxanes typically contain mostly D or

(R2S1O2/2) siloxy units, which results in polydiorganosiloxanes that are fluids of varying viscosity, depending on the "degree of polymerization" or DP as indicated by the number of D units in the polydiorganosiloxane. "Linear" organopolysiloxanes typically have glass transition temperatures (Tg) that are lower than 25 . "Resin" organopolysiloxanes result when a majority of the siloxy units are selected from T or Q siloxy units. When T siloxy units are predominately used to prepare an organopolysiloxane, the resulting

organosiloxane is often referred to as a "silsesquioxane resin". When M and Q siloxy units are predominately used to prepare an organopolysiloxane, the resulting

organosiloxane is often referred to as a "MQ resin". Alternatively, the formula for an organopolysiloxane may be designated by the average of the siloxy units in the organopolysiloxane as follows; RnSiO(4_ _n )/2 _> ^wnere the R is independently any organic group, alternatively a hydrocarbon, or alternatively an alkyl group, or alternatively methyl. The value of n in the average formula may be used to characterize the

organopolysiloxane. For example, an average value of n = 1 would indicate a predominate concentration of the (RS1O3/2) siloxy unit in the organopolysiloxane, while n = 2 would indicate a predominance of (R2S1O2/2) siloxy units. As used herein, "organopolysiloxane resin" refers to those organopolysiloxanes having a value of n less than 1 .8 in the average formula RnSiO(4-n)/2 _> indicating a resin.

[0008] The silicone resin useful as component A) may independently comprise (i)

(R ¹ 3Si0 _{1 /2} )a, (ϋ) (R ² 2Si0 ₂ / ₂ )t ('") (R ³ Si0 ₃ / ₂ )c, and (iv) (Si0 _4/2 )d siloxy units, providing there is at least one T or Q siloxy unit in the silicone resin molecule. The amount of each unit present in the silicone resin is expressed as a mole fraction (i.e., a, b, c, or d) of the total number of moles of all M, D, T, and Q units present in the silicone resin. Any such formula used herein to represent the silicone resin does not indicate structural ordering of the various siloxy units. Rather, such formulae are meant to provide a convenient notation to describe the relative amounts of the siloxy units in the silicone resin, as per the mole fractions described above via the subscripts a, b, c, and d. The mole fractions of the various siloxy units in the present

organosiloxane block copolymers, as well as the silanol content, may be readily determined by 29si NMR techniques.

[0009] The silicone resin may also contain silanol groups (≡SiOH). The amount of silanol groups present on the silicone resin may vary from 0.1 to 35 mole percent silanol groups [≡SiOH], alternatively from 2 to 30 mole percent silanol groups [≡SiOH], alternatively from 5 to 20 mole percent silanol groups [≡SiOH]. The silanol groups may be present on any siloxy units within the silicone resin.

[0010] The molecular weight of the silicone resin is not limiting. The silicone resin may have an average molecular weight (M _w ) of at least 1 ,000 g/mole, alternatively an average molecular weight of at least 2,000 g/mole alternatively an average molecular weight of at least 5,000 g/mole. The average molecular weight may be readily determined using Gel Permeation Chromatography (GPC) techniques.

[0011] In one embodiment, the silicone resin is a MQ silicone. The silicone resin may be a MQ resin comprising at least 80 mole% of siloxy units selected from

(R ¹ 3SiO-|/2) _a and (Si04 2)d units (that is a + d≥ 0.8), where R ¹ is an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group, with the proviso that at least 95 mole % of the R ¹ groups are alkyl groups, a and d each have a value greater than zero, and the ratio of a/d is 0.5 to 1 .5.

[0012] The R1 units of the MQ resin are independently an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group. The alkyl groups are illustrated by methyl, ethyl, propyl, butyl, pentyl, hexyl, and octyl. The aryl groups are illustrated by phenyl, naphthyl, benzyl, tolyl, xylyl, xenyl, methylphenyl, 2- phenylethyl, 2-phenyl-2-methylethyl, chlorophenyl, bromophenyl and fluorophenyl with the aryl group typically being phenyl.

[0013] MQ resins suitable for use as component (A), and methods for their preparation, are known in the art. For example, U.S. Patent No. 2,814,601 to Currie et al., November 26, 1957, which is hereby incorporated by reference, discloses that MQ resins can be prepared by converting a water-soluble silicate into a silicic acid monomer or silicic acid oligomer using an acid. When adequate polymerization has been achieved, the resin is end-capped with trimethylchlorosilane to yield the MQ resin. Another method for preparing MQ resins is disclosed in U.S. Patent No. 2,857,356 to Goodwin, October 21 , 1958, which is hereby incorporated by reference. Goodwin discloses a method for the preparation of an MQ resin by the cohydrolysis of a mixture of an alkyl silicate and a hydrolyzable trialkylsilane organopolysiloxane with water.

[0014] The MQ resins suitable as component A) in the present invention may contain D and T units. The MQ resins may also contain hydroxy groups. Typically, the MQ resins have a total weight % hydroxy content of 2-10 weight %, alternatively 2-5 weight %. The MQ resins can also be further "capped" wherein residual hydroxy groups are reacted with additional M groups.

[0015] In one embodiment, the silicone resin is a silsesquioxane resin. The silsesquioxane resin may be a silsesquioxane resin comprising at least 80 mole % of

R3Si03/2 units, where in the above trisiloxy unit formula is independently a C-| to

C20 hydrocarbyl, a carbinol group, or an amino group. As used herein, hydrocarbyl also includes halogen substituted hydrocarbyls. may be an aryl group, such as phenyl, naphthyl, anthryl group. Alternatively, R^ may be an alkyl group, such as methyl, ethyl, propyl, or butyl. Alternatively, R^ may be any combination of the aforementioned alkyl or aryl groups. Alternatively, R^ is phenyl, propyl, or methyl. In one embodiment, at least 40 mole % of the R^ groups are propyl, referred herein as T- propyl resins, since the majority of the siloxane units are T units of the general formula

R3Si03/2 where at least 40 mole %, alternatively 50 mole %, or alternatively 90 mole % of the R3 groups are propyl. In another embodiment, at least 40 mole % of the R^ groups are phenyl, referred herein as T-phenyl resins, since the majority of the siloxane units are T units of the general formula R3Si03/2 where at least 40 mole %, alternatively 50 mole %, or alternatively 90 mole % of the R^ groups are phenyl. In yet another embodiment, R^ may be a mixture of propyl and phenyl. When R^ is a mixture of propyl and phenyl, the amounts of each in the resin may vary, but typically the R3 groups in the silsesquioxane resin may contain 60 - 80 mole percent phenyl and 20- 40 mole percent propyl.

[0016] Silsesquioxane resins are known in the art and are typically prepared by hydrolyzing an organosilane having three hydrolyzable groups on the silicon atom, such as a halogen or alkoxy group. Thus, silsesquioxane resins can be obtained by hydrolyzing propyltrimethoxysilane, propyltriethoxysilane, propyltripropoxysilane, or by co-hydrolyzing the aforementioned propylalkoxysilanes with various alkoxysilanes. Examples of these alkoxysilanes include methyltrimethoxysilane,

methyltriethoxysilane, methyltriisopropoxysilane, dimethyldimethoxysilane, and phenyltrimethoxysilane. Propyltrichlorosilane can also be hydrolyzed alone, or in the presence of alcohol. In this case, co-hydrolyzation can be carried out by adding methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, or similar chlorosilanes and methyltrimethoxysilane, methyltriethoxysilane,

methyltriisopropoxysilane, or similar methylalkoxysilane. Alcohols suitable for these purposes include methanol, ethanol, n-propyl alcohol, isopropyl alcohol, butanol, methoxy ethanol, ethoxy ethanol, or similar alcohols. Examples of hydrocarbon-type solvents which can also be concurrently used include toluene, xylene, or similar aromatic hydrocarbons; hexane, heptane, isooctane, or similar linear or partially branched saturated hydrocarbons; and cyclohexane, or similar aliphatic hydrocarbons.

[0017] The silsesquioxane resins suitable in the present disclosure may contain M, D, and Q units, but typically at least 80 mole %, alternatively 90 mole % of the total siloxane units are T units. The silsesquioxane resins may also contain hydroxy and/or alkoxy groups. Typically, the silsesquioxane resins have a total weight % hydroxy content of 2- 10 weight % and a total weight % alkoxy content of up to 20 weight %, alternatively 6-8 weight% hydroxy content and up to 10 weight % alkoxy content.

[0018] Representative, non-limiting examples of commercial silicone resins suitable as component A) include; silicone resins sold under the trademarks DOW CORNING®

840 Resin, DOW CORNING® 2-7466 Resin, DOW CORNING® 2-9138 Resin, DOW CORNING® 2-9148 Resin, DOW CORNING® 2104 Resin, DOW CORNING® 2106

RSN-6018 Resin, Xiameter® RSN-0217 Resin, Silres® MK methyl silicone resin, Dow

Corning® MQ 1600 Resin. [0019] As used herein, "silicone resin" also encompasses silicone-organic resins. Thus, silicone-organic resins includes silicone-organic copolymers, where the silicone portion contains at least one (RS1O3/2), or (S1O4/2) siloxy unit. The silicone portion of the silicone-organic resin may be any of the silisesquioxane or MQ resins as described above. The organic portion may be any organic polymer, such as those derived by free radical polymerization of one or more ethylenically unsaturated organic monomers. Various types of ethylenically unsaturated and/or vinyl containing organic monomers can be used to prepare the organic portion including; acrylates, methacrylates, substituted acrylates, substituted methacrylates, vinyl halides, fluorinated acrylates, and fluorinated methacrylates, for example. Some representative compositions include acrylate esters and methacrylate esters such as methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, decyl acrylate, lauryl acrylate, isodecyl methacrylate, lauryl methacrylate, and butyl methacrylate;

substituted acrylates and methacrylates such as hydroxyethyl acrylate, perfluorooctyl acrylate, hydroxypropyl acrylate, hydroxypropyl methacrylate, and hydroxyethyl methacrylate; vinyl halides such as vinyl chloride, vinylidene chloride, and chloroprene; vinyl esters such as vinyl acetate and vinyl butyrate; vinyl pyrrolidone; conjugated dienes such as butadiene and isoprene; vinyl aromatic compounds such as styrene and divinyl benzene; vinyl monomers such as ethylene; acrylonitrile and

methacrylonitrile; acrylamide, methacrylamide, and N-methylol acrylamide; and vinyl esters of monocarboxylic acids.

[0020] The silicone resin selected as component A) may also be a combination(s) of any of the aforementioned silicone resins.

[0021] When component A) is a silicone PSA, it may be the reaction product of a hydroxy endblocked polydimethylsiloxane polymer and a hydroxy functional silicate or silicone resin. Typically, the hydroxy functional silicate resin is a trimethylsiloxy and hydroxy endblocked silicate resin, such as the silicone resins described above. The polydimethylsiloxane polymer and hydroxy functional silicate resin are reacted in a condensation reaction to form the silicone PSA.

[0022] PSAs are disclosed in U.S. Patent Nos.: 4,584,355; 4,585,836; 4,591 ,622; 5,726,256; 5,776,614; 5,861 ,472; 5,869,556; 6,337086, all of which are hereby incorporated by reference for the purpose of disclosing the chemical compositions of PSAs useful as component A) in the present disclosure.

[0023] The silicone PSA may also be a silicone acrylate hybrid composition, as disclosed in WO2007/145996, which is incorporated herein by reference for its teaching of suitable PSA compositions as component A). [0024] Representative, non-limiting examples of commercially available PSA's suitable as component A) include; Dow Corning® Q2-7406 Adhesive, Dow Corning® Q2-7735 Adhesive, Dow Corning® 7355 Adhesive, Dow Corning® 7358 Adhesive, Dow Corning® Q2-7566 Adhesive, Dow Corning® BIO-PSA 7-4102 Adhesive, Dow Corning® BIO-PSA 7-4202 Adhesive, Dow Corning® BIO-PSA 7-4302 Adhesive, Dow Corning® BIO-PSA 7- 4402 Adhesive, Dow Corning® BIO-PSA 7-4502 Adhesive, Dow Corning® BIO-PSA 7- 4602 Adhesive, Dow Corning® BIO-PSA 7-4560, Shin-Etsu KR-100, Shin-Etsu KR-101 - 10, Shin-Etsu SR-130 Momentive PSA518, Momentive SPUR+ PSA 3.0, Momentive SILGRIP PSA529, Momentive SILGRIP PSA915, Momentive SILGRIP PSA610, Momentive SILGRIP PSA595, Momentive SILGRIP PSA6374, and Momentive

SILGRIP PSA6574.

5) The Ethylene oxide/propylene oxide Block Copolymer

[0025] Component B) is an ethylene oxide/propylene oxide block copolymer.

Component B) may be selected from those ethylene oxide/propylene oxide block copolymers known to have surfactant behavior. Typically, the ethylene

oxide/propylene oxide block copolymers useful as component B) are surfactants having an HLB of at least 12, alternatively, at least 15, or alternatively at least 18.

[0026] The molecular weight of the ethylene oxide/propylene oxide block copolymer may vary, but typically is at least 4,000 g/mol, alternatively at least 8,000 g/mol, or at least 12,000 g/mol.

[0027] The amounts of ethylene oxide (EO) and propylene oxide (PO) present in the ethylene oxide/propylene oxide block copolymer may vary, but typically, the amount of EO may vary from 50 percent to 80 percent, or alternatively from 60 percent to about 85 percent, or alternatively from 70 percent to 90 percent.

[0028] In one embodiment, component B) is a poly(oxyethylene)-poly(oxypropylene)- poly(oxyethylene) tri-block copolymer. Poly(oxyethylene)-poly(oxypropylene)- poly(oxyethylene) tri-block copolymers are also commonly known as Poloxamers. They are nonionic triblock copolymers composed of a central hydrophobic chain of polyoxypropylene (poly(propylene oxide)) flanked by two hydrophilic chains of polyoxyethylene (poly(ethylene oxide)).

[0029] Poly(oxyethylene)-poly(oxypropylene)-poly(oxyethylene) tri-block copolymers are commercially available from BASF (Florham Park, NJ) and are sold under the tradename PLURONIC®. Representative, non-limiting examples suitable as component (B) include; PLURONIC® F127, PLURONIC® F98, PLURONIC® F88, PLURONIC® F87, PLURONIC® F77 and PLURONIC® F68, and PLURONIC® F-108. [0030] In a further embodiment, the poly(oxyethylene)-poly(oxypropylene)- poly(oxyethylene) tri-block copolymer has the formula;

HO(CH ₂ CH20) _m (CH2CH(CH3)0) _n (CH2CH ₂ 0) _m H

where the subscript "m" may vary from 50 to 400, or alternatively from 100 to 300, and the subscript "n" may vary from 20 to 100, or alternatively from 25 to 100.

[0031] In one embodiment, component B) is a tetrafunctional poly(oxyethylene)- poly(oxypropylene) block copolymer derived from the sequential addition of propylene oxide and ethylene oxide to ethylene diamine. These tetra-functional block

copolymers are also commonly known as Poloxamines. The tetrafunctional poly(oxyethylene)-poly(oxypropylene) block copolymer may have the average formula; [HO(CH2CH20) _q (CH2CH(CH3)0) _r ]2NCH2CH2N[(CH2CH(CH3)0) _r (CH2CH ₂ 0) _q H]2 where the subscript "q" may vary from 50 to 400, or alternatively from 100 to 300, and the subscript "r" may vary from 15 to 75, or alternatively from 20 to 50.

[0032] Tetrafunctional poly(oxyethylene)-poly(oxypropylene) block copolymers are commercially available from BASF (Florham Park, NJ) and are sold under the tradename TETRONIC®. Representative, non-limiting examples suitable as component (B) include; TETRONIC® 908, TETRONIC® 1 107, TETRONIC® 1307, TETRONIC® 1508 and TETRONIC® 1504.

[0033] The amounts of components A) and B) may vary in the emulsion. Typically the silicone resin emulsions comprise, alternatively consists essentially of, or alternatively consists of:

0.5 to 95 wt. % of A) the silicone resin;

alternatively 5 to 90 wt. % of A) silicone resin,

alternatively 10 to 80 wt. % of A) silicone resin,

alternatively 20 to 70 wt. % of A) silicone resin,

alternatively 30 to 60 wt. % of A) silicone resin, 0.1 to 90 wt. % of B) the ethylene oxide/propylene oxide block copolymer; alternatively 0.1 to 50 wt. % of B) the block copolymer, alternatively 0.5 to 40 wt. % of B) the block copolymer, alternatively 1 to 30 wt. % of B) the block copolymer,

alternatively 1 to 20 wt. % of B) the block copolymer, alternatively 1 to 10 wt. % of B) the block copolymer, and sufficient amounts of water, or other components, to sum to 100 wt%.

[0034] Other additives can also be incorporated in the emulsions of the present disclosure, such as fillers, preservatives, biocides, freeze/thaw additives, anti-freeze agents, various thickeners, viscosity modifiers, and foam control agents. [0035] The emulsion compositions of the present disclosure may be an oil/water emulsion, a water/oil emulsion, a multiple phase or triple emulsion.

[0036] In one embodiment, the emulsion products produced by the present process are "oil/water emulsions", that is, an emulsion having an aqueous continuous phase and a dispersed phase comprising the silicone resin. The oil/water emulsion may be characterized by average volume particle of the dispersed silicone resin (oil) phase in a continuous aqueous phase. The particle size may be determined by laser diffraction of the emulsion. Suitable laser diffraction techniques are well known in the art. The particle size is obtained from a particle size distribution (PSD). The PSD can be determined on a volume, surface, length basis. The volume particle size is equal to the diameter of the sphere that has the same volume as a given particle. The term Dv represents the average volume particle size of the dispersed particles. Dv 50 is the particle size measured in volume corresponding to 50% of the cumulative particle population. In other words if Dv 50 = 10 μηι, 50% of the particle have an average volume particle size below 10 μηι and 50% of the particle have a volume average particle size above 10 μηι. Dv 90 is the particle size measured in volume

corresponding to 90% of the cumulative particle population.

[0037] The average volume particle size of the dispersed silicone particles in the oil/water emulsions is between 0.1 μηι and 150 μηι; or between 0.1 μηι and 30 μηι; or between 0.3 μηι and 5.0 μηι.

[0038] The present emulsions may be prepared by any known methods, or alternatively prepared by the methods as discussed below.

[0039] The present disclosure further provides a process for making a silicone resin emulsion comprising;

I) forming a dispersion of;

A) 100 parts of a silicone resin or PSA,

B) 5 to 100 parts of a ethylene oxide/propylene oxide block copolymer, II) admixing a sufficient amount of water to the dispersion from step I) to form an emulsion,

III) optionally, further shear mixing the emulsion.

[0040] The amount of components A) and B) combined in step I) are as follows;

A) 100 parts of a silicone resin or PSA, and

B) 5 to 100 parts, alternatively 10 to 40 parts, or alternatively 10 to 25 of the ethylene oxide/propylene oxide block copolymer. Components A) and B) are the same as described above.

[0041] As used herein, "parts" refers to parts by weight. [0042] In one embodiment, the dispersion formed in step I) consists essentially of components A) and B) as described above. In this embodiment, no additional surfactants or emulsifiers are added in step I). Furthermore, no solvents are added for the purpose of enhancing formation of an emulsion. As used herein, the phrase "essentially free of "solvents" means that solvents are not added to components A) and B) in order to create a mixture of suitable viscosity that can be processed on typical emulsification devices. More specifically, "solvents" as used herein is meant to include any water immiscible low molecular weight organic or silicone material added to the non-aqueous phase of an emulsion for the purpose of enhancing the formation of the emulsion, and is subsequently removed after the formation of the emulsion, such as evaporation during a drying or film formation step. Thus, the phrase "essentially free of solvent" is not meant to exclude the presence of solvent in minor quantities in process or emulsions of the present invention. For example, there may be instances where the components A) and B) may contain minor amounts of solvent as supplied commercially. Small amounts of solvent may also be present from residual cleaning operations in an industrial process. Preferably, the amount of solvent present in the premix should be less than 2% by weight of the mixture, and most preferably the amount of solvent should be less than 1 % by weight of the mixture.

[0043] The dispersion of step (I) may be prepared by combining components A) and B) and further mixing the components to form a dispersion. The resulting dispersion may be considered as a homogenous mixture of the two components. The present inventors have unexpectedly found that certain ethylene oxide/propylene oxide block copolymers readily disperse with silicone resin compositions, and hence enhance the subsequent formation of emulsion compositions thereof. The present inventors believe other nonionic and/or anionic surfactants, typically known for preparing silicone emulsions, do not form such dispersions or homogeneous mixtures upon mixing with a silicone resin (at least not in the absence of a solvent or other substance to act as a dispersing medium). While not wishing to be limited to any theory, the inventors believe the discovery of the present ethylene oxide/propylene oxide block copolymers to form such dispersions with silicone resins, provides emulsion compositions of silicone resins without the presence of undesirable solvents, or requiring elaborate handling/mixing techniques.

[0044] Mixing can be accomplished by any method known in the art to effect mixing of high viscosity materials. The mixing may occur either as a batch, semi-continuous, or continuous process. Mixing may occur, for example using, batch mixing equipments with medium / low shear include change-can mixers, double-planetary mixers, conical- screw mixers, ribbon blenders, double-arm or sigma-blade mixers; batch equipments with high-shear and high-speed dispersers include those made by Charles Ross & Sons (NY), Hockmeyer Equipment Corp. (NJ); batch mixing equipment such as those sold under the tradename Speedmixer®; batch equipments with high shear actions include Banbury-type (CW Brabender Instruments Inc., NJ) and Henschel type

(Henschel mixers America, TX). Illustrative examples of continuous mixers / compounders include extruders single-screw, twin-screw, and multi-screw extruders, co-rotating extruders, such as those manufactured by Krupp Werner & Pfleiderer Corp (Ramsey, NJ), and Leistritz (NJ); twin-screw counter-rotating extruders, two-stage extruders, twin-rotor continuous mixers, dynamic or static mixers or combinations of these equipments.

[0045] The process of combining and mixing components A) and B) may occur in a single step or multiple step process. Thus, components A) and B) may be combined in total, and subsequently mixed via any of the techniques described above.

Alternatively, a portion(s) of components A) and B) may first be combined, mixed, and followed by combining additional quantities of either or both components and further mixing. One skilled in the art would be able to select optimal portions of components A) and B) for combing and mixing, depending on the selection of the quantity used and the specific mixing techniques utilized to perform step I) to provide a dispersion of components A) and B).

[0046] Step II of the process involves admixing sufficient water to the mixture of step I to form an emulsion. Typically 5 to 700 parts water are mixed for every 100 parts of the step I mixture to form an emulsion. In one embodiment the emulsion formed is a water continuous emulsion. Typically, the water continuous emulsion has dispersed particles of the silicone resin from step I, and having an average particle size less than 150 μηι.

[0047] The amount of water added in step II) can vary from 5 to 700 parts per 100 parts by weight of the mixture from step I. The water is added to the mixture from step I at such a rate so as to form an emulsion of the mixture of step I. While this amount of water can vary depending on the selection of the amount of silicone resin present and the specific ethylene oxide/propylene oxide block copolymer used, generally the amount of water is from 5 to 700 parts per 100 parts by weight of the step I mixture, alternatively from 5 to 100 parts per 100 parts by weight of the step I mixture, or alternatively from 5 to 70 parts per 100 parts by weight of the step I mixture.

[0048] Typically the water is added to the mixture from step I in incremental portions, whereby each incremental portion comprises less than 30 weight % of the mixture from step I and each incremental portion of water is added successively to the previous after the dispersion of the previous incremental portion of water, wherein sufficient incremental portions of water are added to form an emulsion.

[0049] Alternatively, a portion or all the water used in step I) may be substituted with various hydrophilic solvents that are soluble with water such as low molecular weight alcohols, ethers, esters or glycols. Representative non-limiting examples include low molecular weight alcohols such as methanol, ethanol, propanol, isopropanol and the like; low molecular weight ethers such as di(propyleneglycol) mono methyl ether, di(ethyleneglycol) butyl ether, di(ethyleneglycol) methyl ether, di(propyleneglycol) butyl ether, di(propyleneglycol) methyl ether acetate, di(propyleneglycol) propyl ether, ethylene glycol phenyl ether, propylene glycol butyl ether, 1 -methoxy-2-propanol, 1 - methoxy-2-propyl acetate, propylene glycol propyl ether, 1 -phenoxy-2-propanol, tri(propyleneglycol) methyl ether and tri(propyleneglycol) butyl ether, and other like glycols.

[0050] Mixing in step (II) can be accomplished by any method known in the art to affect mixing of high viscosity materials. The mixing may occur either as a batch, semi- continuous, or continuous process. Any of the mixing methods as described for step (I), may be used to affect mixing in step (II). Typically, the same equipment is used to effect mixing in steps I) and II).

[0051] Optionally, the water continuous emulsion formed in step (II) may be further sheared according to step (III) to reduce particle size and/or improve long term storage stability. The shearing may occur by any of the mixing techniques discussed above.

[0052] The present disclosure relates to the emulsions produced by the

aforementioned processes.

[0053] The emulsions of the present disclosure may be further characterized by the properties of the resulting films or coatings produced after allowing a film of the emulsion to dry. Typically, such coatings are obtained by forming a film of the emulsion on a surface, and allowing the film to stand for a sufficient period of time to evaporate the water present in the emulsion, which allows the silicone composition to cure. This process may be accelerated by increasing the ambient temperature of the film or coating.

[0054] In one embodiment, the resulting cured film is transparent and/or tack free.
