HAIR CARE COMPOSITIONS BACKGROUND OF THE INVENTION The present invention is directed to hair care compositions which supply body to the treated hair without giving up conditioning attributes. More particularly, the present invention is directed to hair care compositions and a method for treating hair which supply body to the treated hair without giving up conditioning attributes. In the past, it has been difficult to achieve good hair body from a hair treatment composition without giving up conditioning attributes. Moreover, while styling would ordinarily be considered a measure of hair body, prior art compositions have failed to deliver good styling attributes. The present invention overcomes these deficiencies. Other products in the market give either body or conditioning. The present invention gives both body and conditioning.

U. S. Patent No. 4,902,299 to Bolich et al. teaches styling benefits, which may not provide the combination of body and conditioning, from rigid silicone polymers having complex viscosities greater than 107 poise when delivered from a rinse-off product (shampoo or conditioner). They also require a volatile carrier which is typically a linear or cyclic silicone or hydrocarbon. This volatile carrier exhibits a solubility in water of less than 0.1% and is present at a level between 0.1 and 99.9% However, we have measured the complex modulus of the SR-545 material described in the patent and determined that at 5.28x10-2

dynes/cm2 it is four orders of magnitude lower than the materials in our invention.

U. S. Patent No. 4,842,850 to Vu teaches styling benefits from a rigid silicone polymer contained in a shampoo. He also claims a volatile silicone carrier at a range from 1- 10% of the total composition.

PCT/EP96/01462 Birtwistle et al., which is hereby incorporated by reference, teaches a hair care composition containing a non-rigid emulsion polymerized cross linked conditioning agent having a viscosity between 106-109 cts.

SUMMARY OF THE INVENTION The present invention is directed to hair care compositions which supply body to the treated hair without giving up conditioning attributes. More particularly, the present invention is directed to hair care compositions and a method for treating hair which supply body to the treated hair without giving up conditioning attributes. In the past, it has been difficult to achieve good hair body from a hair treatment composition without giving up conditioning attributes. Moreover, while styling would ordinarily be considered a measure of hair body, prior art compositions have failed to deliver good styling attributes. The present invention overcomes these deficiencies.

More specifically, this invention relates to aqueous or non- aqueous hair care compositions including conditioners,

shampoos, and mousses. Conditioners include rinse-off and leave-in conditioners.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to aqueous and non-aqueous hair care compositions including for example, conditioners, shampoos, hair sprays and mousses.

Conditioners include rinse-off and leave-in conditioners.

The invention also relates to methods of treating hair, and more particularly to treating hair with aqueous hair care compositions which contain one or more elastomeric resinous materials. As noted above, these elastomeric materials when tested at the same concentration that would be incorporated into a product exhibit a G'modulus between 1x102 and 1x105 dynes/cm2. Furthermore these resins when mixed with a hydrophilic or hydrophobic diluent at a ratio of 1: 95 to 95: 1% and this mixture then incorporated into an aqueous emulsion in the range of 0.1 to 10% have been demonstrated

to deliver a consumer perceptible increase in hair body without sacrificing conditioning attributes.

Previous work has demonstrated that silicone resins of high viscosity 105-109 poise are required to yield styling benefits from a rinse off product (Bolich et al., Birtwistle et al. and Vu). All of our previous work indicates that styling is an important component of body in the consumers' mind. Thus, one would expect that a material that is capable of delivering styling would also deliver body. <BR> <BR> <BR> <P>However, we have found that not all resins in the 105-109 poise range are capable of delivering on consumer perceptible body. Additionally, resins that fall well below the 105-109 poise range also deliver on body. What we have found, unexpectedly, is that it is not the viscosity of the neat resin that determines if it will deliver body.

What is important is the viscosity of the resin when mixed with a hydrophilic or hydrophobic diluent that is then incorporated into the final formulation.

The one or more elastomeric resinous materials that can be included in our compositions are any elastomers that have the G'and G''measurements set forth in this specification. These elastomers include non-silicone elastomers or more preferably cross-linked or uncross-linked silicone elastomers.

Moreover, the degree of crosslinking of silicone elastomers affects their performance in the compositions of the invention. Preferred silicone elastomers for use in the invention are polydiorganosiloxanes, preferably derived from

suitable combinations of R3SiOo. 5 units and R2SiO units where each R independently represents an alkyl, alkenyl (e. g. vinyl), alkaryl, aralkyl, or aryl (e. g. phenyl) group. R is most preferably methyl.

The preferred crosslinked silicone elastomers of the invention are cross-linked polydimethyl siloxanes (which have the CTFA designation dimethicone), optionally having end groups such as hydroxyl or methyl.

One preferred elastomer of the invention is DC 2-9040.

DC 2-9040 Cross-linking Chemistry is as follows.

The cross linker used in the DC 2-9040 is an alpha, omega aliphatic diene of the following structure: CH2=CH (CH2) XCH=CH2, where X ranges from 1-20. A gel is formed by crosslinking and addition of Si-H across double bonds in the alpha, omega-diene. The following Dow Corning patent describes the DC 2-9040: US 5,654,362. This just mentioned US patent is hereby incorporated by reference.

Another preferred elastomer of the invention is DC 3-2365.

The structure of the cross-linker used in DC 3-2365 is given below:

x+y=7-24 Another preferred elastomer of the invention is Silicone/Urethane Copolymer.

The structure of the urethane cross-linker is given below:

The tradename for the silicone-urethane copolymer is Polyderm PPI-SI-100. The supplier is Alzo Incorporated, Matawan, New Jersey.

The degree of crosslinking of the silicone elastomers is suitably from about 0.05% to about 35%, preferably being in the range of about 0.15% to about 7%, e. g. from about 0.2 to about 2%.

Suitable emulsion polymerized cross-linked silicone elastomers are commercially available or can be readily made using conventional techniques well known to those skilled in the art.

G'and G''are well-recognized moduli that are used in measuring the physical properties of viscoelastic fluids as can be seen from"Viscoelastic Fluids"Ronald Darby pages 106 through 115, published by Marcel Dekker, Inc. (1976) which are hereby incorporated by reference.

G'and G"are components of the complex modulus, G*, that is used to characterize the viscoelastic behavior of polymers.

G'represents the elastic or solid-like character of the polymer, and G"represents the viscous or liquid-like character of the polymer. The G'and G"components of the complex modulus are derived from relationships between the oscillatory stress and the oscillatory strain.

The G'and G"rheological measurements were carried out using a Bohlin VOR rheometer (Bohlin Instruments, Inc.). Two measuring geometries were used. The choice of geometries is based on the viscosity and the volume of the material to be measured. For lower viscosity polymer fluids, such as GE SR 1000 in 50% DC 245 and Dow Corning X2-1787, the C25 cup and bob geometry was employed. The diameter of the bob was 25 mm with a gap spacing of 1.25 mm. For higher viscosity polymer fluids, such as DC 2-9040 in DC 245 and Polyderm PPI-SI-100 in Myristyl Ether Propionate, the parallel plate geometry was used. The diameter of the upper plate was 30 mm and the gap spacing of 1 mm was used. All tests were run at 25°C.

In carrying out a dynamic viscosity measurement, the first step was to establish the viscoelastic region. Initially,

the strain amplitude at constant frequency was increased and the moduli were plotted versus the amplitude in order to establish the linear viscoelastic region. Once the viscoelastic region was established, oscillatory measurements were carried out at one amplitude within the linear viscoelastic region as a function of frequency. The Bohlin VOR rheometer is capable of covering the frequency range of 0.01 to 125 rad/sec.

From the stress, to, and strain, go, amplitudes, and from the phase-angle, delta, the following expressions are derived: where G* is the complex modulus, G'the storage modulus (elastic component of G*), G"is the loss modulus (viscous component of G') and i is equal to (-1) 1/2.

The elastomeric resinous materials used in the compositions have G'and G''measured after they are mixed with the

hydrophilic or hydrophobic diluent and before the final product is prepared.

The G'modulus of these elastomeric resinous materials after the mixing with diluent is about 1X102 to lX107 dynes/cm2 or, more preferably, 1X102 to 1X105 dynes/cm2. The G'' modulus of these elastomeric resinous materials after mixing with diluent is about lX102 to lX105 dynes/cm2 or, more preferably, 1X102 to 1X104 dynes/cm2.

As noted above, in compositions of our invention the elastomeric resinous materials are mixed with a hydrophilic or hydrophobic diluent such as PPG-2 Myristyl Ether Propionate or cyclomethicone.

The weight ratio of elastomeric resinous material to diluent may run from about 1: 95 to about 95: 1.

The mixture is then made into an aqueous emulsion wherein the resulting elastomer concentration is in a weight per cent range of about 0.1 to about 10 %.

Salon Blitz Testing The following Salon Blitz Testing table is a summary of the results from a series of salon tests conducted over a period of approximately 12 weeks. The benchmark for this studies is the best selling commercial extra body conditioner in the North American market. These data indicate that the formulations containing DC 2-9040 (Ex A.), Silicone/Urethane (Ex. B.) and Polyisobutylene (Ex. F) outperformed the Benchmark formulation in both overall conditioning and in their ability to deliver hair body as reported by the models. The X2-1787 resin (Ex. C.), DC2-1391 (MOD)-High MW resin (Ex. D.) and Silicone Gum Blend 33/67 (Ex. G) did not show any body attribute benefit over the Benchmark. Both the formulations containing DC-9040 (Ex. A) and the Silicone/Urethane (Ex. B) have G'modulus values in the discovered range while the DC-1787 prototype exhibited a very low modulus.

The test results were obtained by using the following method: Salon Blitz Protocol Salon Blitz utilizes female conditioner users as the panelists. In a salon, a professional hair stylist will apply the test product to 1/2 of the head and the benchmark product to the other side of the panelist's head. Once product is applied, the stylist distributes the product evenly and rinses it out taking care to keeping both sides separated. The panelists then are asked to dry and style their own hair. A questionnaire is provided to each panelist asking them to rate (on a 9 point scale) hair

characteristics (e. g. conditioning and body) for both the left and right side of the head. Typically at least 12 panelists (n ranges from 15-100) are recruited for each test product evaluation. Higher values for key characteristics such as conditioning or body indicates a higher intensity for these attributes. Compositions Bench- Ex. A Ex B Ex C Ex D Ex.

Consumer Sensory Testing The data presented in the table below summarizes the conditioning and body attribute results from a larger scale take home study. Again the formulation containing DC-9040 was demonstrated to provide superior conditioning and body benefit versus the commercial body conditioner. These data confirm the results from the smaller salon test described above.

The below test results were obtained by using the following method: Consumer Sensory Test (CST) Protocol The CST format utilizes female conditioner users to participate in a home use study. The benchmark or prototype samples are randomly distributed to the panelists. The samples are blinded to avoided any branding bias. Each participant will take the sample home and use as they would their normal conditioner for 1 week period. After the one week usage period the panelist fills out a questionnaire asking them to rate (on a 9 point scale) the characteristics of the sample just used. Another sample is provided to the participant and used for 1 week. At the completion of the second week the panelist will fill out an identical questionnaire asking them to rate (same scale) the characteristics of the second sample just used. Typically at least 50 panelists (n ranges from 50-75) are recruited for each test product evaluation. Higher values for key characteristics such as conditioning or body indicates a higher intensity for these attributes. Compositions Benchmark Ex. A Ex.

Complex Moduli for Selected Resins in our Study The table below lists the G'and G"moduli that have been completed thus far for the formula tested in our salon test and referred to in the literature. Those samples falling in the G'range of 1x102 to 1x105 (DC-9040 and Silicone/Polyurethane) have been shown in both in-house and take home consumer test to deliver both conditioning and body relative to a commercial bodyfing conditioner. The X2- 1787 material which falls in a range well below that of our invention has been demonstrated not to deliver consumer recognizable conditioning or body. The GE SR-1000 moduli are included to demonstrate the difference between our invention and that of Bolich et al. The G'modulus of their material 5.2x10-2 clearly differentiates our invention from theirs.
