     FIELD OF THE INVENTION 
     The present application relates to a composition and a process involving applying the composition onto hair, wherein the composition contains an thiol-based compound selected from thiolactic acid and its derivatives or its salts, and wherein the composition has a pH of less than 7. 
     BACKGROUND OF THE INVENTION 
     Cosmetic and personal care products for use on keratinous substrates such as hair are available commercially in various forms, for example, as creams, lotions, gels, pastes, and powders. Regardless of the form, these products have to achieve and provide certain benefits and attributes such as efficaciousness, cosmeticity, desirable texture, stable formulations, and ease and convenience of use and application. Thus, in order to meet changing consumer needs and preferences, manufacturers of such products continuously seek to re-formulate and create new products with enhanced efficacy, while still remaining stable and safe to use. In addition, manufacturers continue to test the use of new raw materials and ingredients or new product forms that would help deliver the desired attributes and properties with respect to viscosity, texture, stability and efficacy. 
     One area where manufacturers are always seeking to improve in is in the area of hair cosmetic products such as those products designed to change the appearance, shape or configuration of hair as well as to provide hair care benefits of manageability, frizz control, volume reduction, and improved quality of the hair fiber. Examples of such hair cosmetic products are hair relaxers or hair straighteners which can relax or straighten curly or kinky hair, including wavy hair. Other hair cosmetic products are perms and waving compositions for providing curl or shape to hair. These products may increase the manageability and ease of styling hair and they may either be applied in a hair salon by a professional or in the home by the individual consumer. 
     One type of composition that can be applied onto hair in order to change its shape and make it more manageable is an alkaline composition. Alkaline hair relaxing/straightening involves hydrolyzing the keratin of the hair with various alkaline agents, such as inorganic hydroxides, for instance sodium hydroxide, or organic hydroxides, such as guanidine hydroxide, or organic amines. Hair relaxing/straightening products that employ sodium hydroxide or potassium hydroxide are also called lye-based products and products that use other alkaline agents such as lithium hydroxide, calcium hydroxide, organic hydroxides and other non-hydroxide compounds, for example, organic amines, generally fall under the category of no-lye products. 
     Still, it is desirable to find alternatives to the alkaline lye- and no-lye-based products and process described above which can damage the hair by weakening and/or causing dryness of the hair fibers. However, the discovery of new compositions and processes for changing the shape of hair that impart less or minimal damage to hair, may pose challenges to manufacturers and formulators because the incorporation of new ingredients into the compositions may negatively impacting their performance, cosmetic attributes, and formulation stability. In addition, the alkalinity and/or pH is an important consideration for these products. New processes of treating and changing the shape of hair may also impact the performance of the compositions, processing times and quality of use. 
     The present invention provides a hair cosmetic composition for shaping or altering the shape of hair or caring of the hair, the composition containing an thiol-based compound selected from thiolactic acid, thiolactic acid derivatives, their salts, and mixtures thereof, optionally a neutralizing agent, and water, wherein the composition is non-alkaline such that its pH ranges from about 2 to less than about 7. The present invention also provides a process for shaping or altering the shape of hair or caring of the hair, such as by straightening the hair or by providing improved manageability to the hair, in an easy and efficacious manner, the process comprising applying onto the hair, said composition and heating the hair while optionally applying a smoothing action on the hair, and optionally, rinsing the hair with water or contacting the hair with an intermediate agent selected from a shampoo and/or a conditioner, followed by rinsing with water. The treatment of hair in accordance with the process of the present disclosure can be followed by a step of contacting the hair with a neutralizing composition containing an oxidizing agent. Such neutralizing composition can be a rinse-off or leave-in product. The hair can also be contacted with a pre-treatment composition such as a shampoo, then rinsed with water before the hair cosmetic composition is applied onto the hair or other pre-treatment compositions which may be leave-in or rinse-off compositions. 
     It was surprisingly and unexpectedly discovered that the composition of the present invention, when applied onto hair fibers, result in an effective process of shaping or altering the shape of hair or providing hair care benefits to hair such as manageability, frizz control and volume reduction. In addition, the process of the invention allows the straightening or texlaxing (results in wavy hair) of hair while at the same time, limiting or avoiding the degradation of hair resulting from alkaline systems and maintaining desirable working conditions, especially since there is no excessive vaporization of the composition at the time of treating the hair in accordance with the hair treatment process according to the invention. The hair treatment process according to the invention also makes it possible to minimize the problems of breakage of the hair fibers. The composition and the process of the invention were also found to improve the physical properties and appearance of hair, by durably reducing or controlling the volume and frizziness of hair.

     Swatch evaluation was performed on curly or wavy hair swatches (virgin hair, i.e., not chemically treated) in accordance with the assessment method in Example 1B above. From the table above, it was found that at similar pH values, the degree of straightening increased as the level of thiolactic acid increased.

     The gel compositions above were each prepared according to the general procedure: 
     2. Heat water to about 70° C. 
     3. Add the cellulose material and keep the temperature at about 70° C. and agitate the mixture for 30 minutes. 
     4. Add the silicone material and mix for another 15 minutes at 70° C. 
     5. Cool to 25° C. 
     6. Add the neutralizing agent at 25° C. with agitation and then add the thiolactic acid. 
     7. Adjust the pH and check the viscosity. 
     The viscosity of the inventive composition was measured using the Mettler RM 180 Rheomat, viscometer spindle #2, at 25° C. (uD=Units of Deflection). 
     A viscosity measurement in M2 units ranging up from about 60 to 65 M2 corresponded to a texture and consistency of a gel composition. The gel texture provided the benefits of ease of application of the composition into the hair, spreadability of the composition on the hair, and/or ease of brushing or combing the hair. The gel compositions did not readily drip off the hair contacted with the compositions and remained on the hair during the straightening processing time.

     The emulsion compositions above were each prepared according to the general procedure: 
     1. Heat water to about 60° C. 
     2. Add the PPG-5-ceteth-20 and keep the temperature at about 60° C. and agitate the mixture for 10 minutes. 
     3. Combine Ceteth-10 Phosphate, Cetearyl alcohol, Polyquaternium-67 (if present), and Mineral Oil and mix for another 25 minutes at 60° C. and add to PPG-5 cetheth-20 and water mixture. 
     4. If present, stir Polyquaternium-6 for 10 minutes at 40° C. and add to resulting mixture. 
     5. Combine the neutralizing agent at 25° C. with agitation and then add the thiolactic acid. 
     6. Adjust the pH and check the viscosity. 
     The viscosity of the inventive composition was measured using the Mettler RM 180 Rheomat, at 25° C. (uD=Units of Deflection). 
     Viscosity measurements corresponded to a texture and consistency of an emulsion or cream composition. The cream texture provided the benefits of ease of application of the composition into the hair, spreadability of the composition on the hair, and/or ease of brushing or combing the hair. The emulsion composition with the cream texture also did not readily drip off the hair contacted with the composition and remained on the hair during the straightening processing time. 
     The consistency and texture of the inventive formulas above (aqueous, gel and emulsion) allow for the formulas to be packaged in various ways, such as in jars, in tubes (e.g., squeeze tubes) or in bottles (eg, applicator bottles). 
     The formulas above were also found to be stable. Stability was measured by placing the formulas in a humidity-controlled environment set at 4° C., 25° C. and 45° C. for at least 2 months. The formula was considered to be stable when no phase separation is observed and there were very little fluctuations in viscosity and pH.

     Assessments of Performance and Straightening or Smoothing, Reduction of Frizziness and Volume of Hair 
     The performance of the compositions in Example 2 on hair was assessed according to the assessment method described in Example 1B. 
     Assessments were performed on hair swatches before treating the swatch with the gel composition, formula A, after treating a swatch with formula A by subjecting the swatch to the above-described rinsing protocol (process 1), and after treating a swatch with formula A by subjecting the swatch to the above-described non-rinsing protocol (process 2), It was found that the gel formula A significantly straightened the hair from a curly state, imparted excellent discipline to the hair (i.e., very low amount of or no frizz) and significantly reduced the volume of the hair. 
     For formulas B to E, it was observed that the degree of straightening and/or discipline and/or volume reduction was comparable to formula A. However, the hair treated with formula A had better or increased natural feel to the touch. 
     It was also found that the use of hydroxyethylcellulose in the gel formulas improved the quality and process of straightening the hair, i.e, it was easier to brush the hair and the flat iron plates slid/passed better or easier over the hair. 
       FIG. 1  shows images of images of hair swatches before treating the swatch with the emulsion composition, formula G, after treating a swatch with formula G by subjecting the swatch to the above-described rinsing protocol (process 1), and after treating a swatch with formula G by subjecting the swatch to the above-described non-rinsing protocol (process 2), It was found that the emulsion formula significantly straightened the hair from a curly state, imparted excellent discipline to the hair (i.e., very low amount of or no frizz) and significantly reduced the volume of the hair. 
     The hair swatch subjected with formula G and the rinsing protocol (process 1) had a measurement of 4, which indicated the greatest degree of straightening and reduction of frizziness to the hair. The hair swatch subjected with formula G and the non-rinsing protocol (process 2) had a measurement of 3, which also showed a significant degree of straightness and reduction of frizziness in comparison to the hair swatch before treatment.
