Description: HAIR CARE COMPOSITIONS AND METHOD FOR DEPOSITING SWOLLEN POLYMER PARTICLES ONTO HAIR FIELD OF THE INVENTION The present invention is directed to hair care compositions and a method for conditioning and bodifying the hair. The hair care compositions which impart body to the treated hair without giving up conditioning attributes. In particular, the present invention relates to hair care compositions comprising one or more solvent-swollen polymer systems in a water or hydroalcoholic carrier, and a method for conditioning and bodifying human hair. BACKGROUND OF THE INVENTION In the past, it has been difficult to deliver good hair body from a hair treatment composition without giving up conditioning attributes. There is a consumer need for a conditioner to provide more than the typical conditioning attributes which include improved wet and dry combing properties; freedom from static charge buildup; enhanced feel and softness. The current conditioner technology has not successfully addressed the need for incorporating enhanced body (improved resiliency and bounce) and style creation without sacrificing the conditioning attributes. EP 295 903 A discloses a hair preparation having high sebum absorptivity comprising a carrier and a fine particulate oil absorptive compound such as porous polyvinyl polymer. Enhanced body of hair is not discussed. It is an object of this invention to provide hair care compositions utilizing polymer systems which can provide improved body, resiliency and bounce while maintaining the wet and dry properties expected from a conditioner. SUMMARY OF THE INVENTION The present invention relates to a hair conditioning composition and a method of treating hair, and more particularly to aqueous hair conditioners which contain one or more polymer systems. The hair conditioner compositions deposit swollen particles onto the hair surface rather than continuous films. The particle systems are incorporated into hair conditioning compositions in the range of 0.1 to 20%. The formulations deposit discrete swollen particles onto hair with total surface coverage ranging from 0.001 to 50%. These formulations have been demonstrated to deliver a consumer perceptible increase in hair body and style enhancement without sacrificing conditioning attributes. More specifically, the invention relates to hair care compositions which comprise (a) one or more polymer systems in the form of discrete particles, wherein said particles are swollen with a non-aqueous solvent; and (b) water or a hydroalcoholic solution carrier. DETAILED DESCRIPTION OF THE INVENTION As used herein % means weight % of the total composition unless otherwise indicated. Compositions of the invention can be made by methods that are analogous to methods that are known in • the art . As used herein discrete particles means material that exists as independent, irregular or spherical masses. When referring to material deposited on a surface, discrete particles means deposited materials that are not in the form of continuous films, and have a variable thickness on the substrate surface. As used herein swollen polymer systems means polymers that increase their volumes by absorbing compatible solvents into their structures . As used herein total surface coverage means the percentage of total surface area of the substrate surface that is occupied by the deposited material. Scanning electron microscopy of hair treated with compositions of the invention at 3,000 X magnification showed a discrete, air dried, DC 2-9040 particle on the surface of the hair fiber cuticle. "DC 2-9040" is a cross-linked polydimethyl siloxane suitable for use in compositions of the invention, as will be described more fully hereinafter. The hair fibers were prepared for scanning electron microscopy as follows: The hair fibers were treated with a composition of the present invention and the composition was rinsed from the hair. The hair fiber (s) were air dried, mounted onto an aluminum specimen holder and examined under the microscope at 10 kV. The composition of the invention that was used, was a Finesse Extra Body Conditioning base to which was added 4.7% of a mixture of 10% DC 2-9040 in cyclomethicone . The present invention relates to 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 materials which deposit swollen, polymer particles on the hair. These materials can be crosslinked polymers that swell in compatible solvents, but do not dissolve in the solvent . One aspect of this invention relates to a hair conditioning composition and a method of treating hair, and more particularly to compositions that contain one or more swollen polymer systems. These polymers are swollen with a solvent that may also be present in excess in the hair care composition of the invention. The swollen polymer systems are incorporated into hair conditioning compositions in the range of 0.1 to 20%. When the swollen polymers are dispersed within the conditioner, the swollen polymers exist as discrete swollen polymer particles in the conditioner. These hair conditioner compositions deposit swollen polymer particles onto the hair surface rather than continuous films. The formulations deposit discrete, swollen polymer particles onto hair with total surface coverage ranging from 0.001 to 50%. These formulations have been demonstrated to deliver a consumer perceptible increase in hair body and style enhancement without sacrificing conditioning attributes . Traditional conditioners deposit their conditioning and bodifying agents as continuous films. Continuous films negatively impact body and style enhancement. The present invention, by contrast, deposits discrete particles onto the hair surface that enhance hair body, and they aid in the creation of a hairstyle. Common wisdom held by those skilled in the art would suggest that deposition of discrete particles would lead to unacceptable sensory attributes such as excessive roughness. Surprisingly, we have found that deposition of discrete, swollen particles leads to body and style enhancement without unacceptable sensory attributes. The one or more polymeric materials that can be included in our compositions are any polymers that deposit as discrete particles on the hair, and wherein said particles have been swollen by the uptake of solvent are also in the compositions of the present invention. Examples of materials capable of producing swollen polymer particles include silicone polymers and surface-alkylated spherical silicon particles. A discussion of the use of silicone polymers as the materials that deposit swollen particles when dispersed in the compositions of the invention now follows. Preferred silicone polymers for use in the invention are polydiorganosiloxanes and polymonoorganosiloxanes . The polydiorganosiloxanes are preferably derived from suitable combinations of R 3 SiO 0 . 5 units and R 2 SiO units. The polymonoorganosiloxanes are preferably derived from RιSiOι. 5 . Each R independently represents an alkyl, alkenyl (e.g. vinyl), alkaryl, aralkyl, or aryl (e.g. phenyl) group. R is most preferably methyl . The degree of crosslinking of silicone polymers affects their performance in the compositions of the invention. The preferred silicone polymers of the invention are cross- linked polydimethyl siloxanes and polymonomethyl siloxanes optionally having end groups such as hydroxyl or methyl . One preferred polymer of the invention is DC 2-9040, a crosslinked polydimethyl siloxane. 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: CH 2 =CH(CH 2 ) X CH=CH 2 , where X ranges from 1-20. A crosslinked polymer network is formed by 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. The degree of crosslinking of the silicone polymers 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 polymers are commercially available or can be readily made using conventional techniques well known to those skilled in the art . The silicone polymer is swollen by mixing the polymer with a thermodynamically compatible solvent. The preferred solvents are those derived from linear low molecular weight polydimethyl siloxanes and cyclic low molecular weight polydimethyl siloxanes. The most preferred solvent is the cyclic pentamer polydimethyl siloxane. The swollen polymer may be made into an aqueous emulsion or dispersion wherein the resulting polymer concentration is in a weight percent range of about 0.1 to about 10 %. In making our compositions, conventional means known to those skilled in the art are employed. Another example of a swollen polymer system which can deposit as discrete swollen particles on the hair surface are the polymonomethyl siloxanes. The polymonomethyl siloxanes are marketed under the trade name Tospearl, obtainable from Toshiba Silicones, Tokyo, Japan. The preferred solvents are the linear low molecular weight polydimethylsiloxanes and the cyclic low molecular weight polydimethyl siloxanes.

The following examples serve to illustrate and not to limit the scope of the present invention. Example Formulations All the examples were prepared using softened or deionized water. As used herein, benchmark means control. Swollen particles can be utilized alone or in combination as the below examples show. Test 1 Preparation and Sensory Evaluation of Samples on Tresses for Rinse off Products 1. Wash 2g tresses with 1ml Suave ® Strawberry Shampoo for thirty seconds, rinse with 45°C water at constant flow for thirty seconds . 2. Apply 0.5ml conditioner to the tress and massage into the hair. 3. After one minute, rinse the tress for thirty seconds as in step 1. 4. Evaluate wet combing with a small toothcomb versus control . 5. Dry tresses with a blow dryer. 6. Dry combing is evaluated with a small toothcomb and ranked from easiest combing to more difficult. 7. The overall dry character of the tress is evaluated by using the fingers . 8. Tresses were next curled with a hot curling iron for 20 seconds . The bounce or curl memory was then ranked . 9. Attributes are force ranked from l=best to 5=worst. Table 1. Sensory properties of swollen particle conditioners versus a control conditioner and bleached untreated hair. From Table 1, the curl memory is enhanced through the addition of swollen particles on the hair without affecting conditioning attributes. Examples of Leave-in Conditioners Test 2 was the same method as described in Test 1 with conditioner allowed to remain on the hair. Table 2. Sensory properties of swollen particle conditioners on hair versus a control conditioner and bleached untreated hair. Table 2 shows that the addition of swollen particles can enhance the wet and dry properties and enhance curl memory as a leave-in conditioner as well. Salon and Consumer Testing of Conditioning and Body Attributes The following examples were prepared for consumer studies, Examples Q and R 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 these studies is the best selling commercial extra body conditioner in the North American market . These data indicated that the formulations containing DC 2-9040 (Ex Q.) outperformed the Benchmark formulation in both overall conditioning and in its ability to deliver hair body as reported by the models. The Silicone Gum Blend 33/67 (Ex. R) did not show any body • attribute benefit over the benchmark. Test 3 - Salon Blitz Salon Blitz utilized female conditioner users as the panelists. A professional hair stylist applied the test product to half of the head and the benchmark product to the other side of the panelist's head. Once product has been applied, the stylist distributed the product evenly and rinsed it out taking care to keeping both sides separated. The panelists then dry and style their own hair. A questionnaire was 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. Higher values for key characteristics such as conditioning or body indicates a higher intensity for these attributes and therefore better performance on the hair. At least 17 panelists (n=17 to 92) were recruited for each test product evaluation. Results for this test are shown in Table 3. Table 3. Salon testing of examples Q and R versus benchmark conditioner. The above table shows that Example Q delivered body without affecting conditioning performance. Consumer Sensory Testing The data presented in table 4 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: Test 4 Consumer Sensory Test (CST) The CST format utilized female conditioner users n a home use study. The benchmark or prototype samples were randomly distributed to the panelists. The samples were blinded to avoid any branding bias. Each participant took the sample home and used it for a one-week period. After the one-week usage period, the panelist filled out a questionnaire regarding performance characteristics. This questionnaire was based upon a nine point rating scale (l=low to 9= high) . A second sample was then provided to the participant and used for one week. At the completion of the second week, the panelist filled out an identical questionnaire asking them to rate (same scale) the characteristics of the second sample. At least 50 panelists (n ranged from 52-57) were recruited for each test product evaluation. Higher values for key characteristics such as conditioning or body indicated a higher intensity for these attributes. Table 4. Consumer Sensory Test From table 4, it was shown that body attributes were enhanced with Example Q without sacrificing conditioning benefits.
