Description:
FIELD OF THE INVENTION 
     This invention is directed to the hair treatment field, more particularly to the treatment of natural excessively tightly curled hair that has been subjected to a change in shape, such as straightening or curling processes. 
     BACKGROUND OF THE INVENTION 
     Excessively tightly natural curled hair, such as of persons of certain African or Middle Eastern descent, tends to tangle and is difficult to comb. It is popular for hair styling to straighten the naturally excessively curly hair. Many commercial products and developments have been directed to the straightening or “relaxing” such hair. Typical straightening processes use alkalis, such as sodium hydroxide. All of these straightening products tend to injure the hair to varying degrees, resulting in split ends, weakened tensile strength, and compositionally weakened hair strands. It is reported that the straightening process results in chemical degradation of the cysteine bonds of the hair strands. Commercially available “conditioners” fail to provide a satisfactory solution. Prior art compositions and methods for hair treatment are provided herein below and in the comparison examples provided later in the patent.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     A unique nature of this invention is that the ingredients contained in this invention work together in a manner that allows the strength of the hair to be regained after its shape has been changed as a result of treatment with alkali. More specifically, this invention allows the emollients and fatty acids to be delivered to the hair and results in arresting the process of excessive breakage of the disulfide bonds in the hair keratin proteins. The proposed mechanism, based on the scientific literature is as follows: The non-ionic surfactant, such as Triton X-100, gently opens the keratin strands to allow the emollients and the fatty acid to penetrate into the protein structure. Once in, the fatty acid neutralizes the excess alkali resulting in the formation of fatty acid soap, and the emollients provide the moisture needed for the disulfide bonds and electrostatic interactions to reestablish themselves. Neutralization of the excess alkali is an essential step in preventing excessive breakage of the disulfide bonds, and allows the reformation of these bonds, thereby allowing the hair to retain its natural strength. The lack of strong electrolytes in the system allows the electrostatic interactions among the amino acid residues in the hair keratin to operate and help maintain the hair strength while the disulfide bonds are being renewed (Crewther, W. G. and Dowling, L. M.,  Proc. Internat. Wool Textile Res. Conf. Paris  (CIRTEL), 1965, 2, 393.). Furthermore, the low ionic strength of this invention prevents the formation of too many “lanthionine” bonds in the hair protein, which is detrimental to the hair and renders the hair untreatable with thioglycollic acid preparations. In summary, this invention has the unique combination of ingredients to reestablish the hair strength in its new shape, thereby preventing the common problems of weakened hair after an alkali treatment. 
     Important ingredients of the present invention fall into the general category of emollients that include, but are not limited to hydrocarbon oils and waxes, such as mineral oil, petrolatum, and the like, vegetable and animal oils and fats, such as olive oil, palm oil, castor oil, corn oil, soybean oil, and the like, and lanolin and its derivatives, such as lanolin, lanolin oil, lanolin wax, lanolin alcohols, and the like. Other emollients include esters of fatty acids having 10 to 20 carbon atoms, such as including myristic, stearic, isostearic, palmitic, and the like, such as methyl myristate, propyl myristate, butyl myristate, propyl stearate, propyl isostearate, propyl palmitate, and the like. Other emollients include fatty acids having 10 to 20 carbon atoms, including stearic, myristic, lauric, isostearic, palmitic, and the like. Emollients also include fatty alcohols having ten to twenty carbon atoms, such as cetyl, myristyl, lauryl, isostearyl, stearyl and the like. Although some are water soluble, polyhydric alcohols and polyether derivatives are included as emollients, including glycols, glycerol, sorbitol, polyalkylene glycols and the like, such as propylene glycol, dipropylene glycol, polyethylene glycol 200-500, and the like. The water soluble examples are preferred. 
     Another important ingredient is an emulsifier/surfactant and nonionic surfactants are preferred which are broadly described as polyoxyalkylene oxide condensation products of hydrophobic alkyl, alkene, or alkyl aromatic functional groups having a free reactive hydrogen available for condensation with hydrophilic alkylene oxide, polyethylene oxide, propylene oxide, butylene oxide, polyethylene oxide or polyethylene glycol to form nonionic surfactants. Particularly effective are the condensation products of octylphenol with about 7 to about 13 moles of ethylene oxide, sold by the Rohm &amp; Haas Company under their trademark TRITON® 100 series products. 
     Other ingredients are included in the compositions for purposes and in quantities well known in the art to be effective, including but not limited to fragrances, stabilizing agents, dyes, antimicrobal agents, antibacterial agents, anti agglomerates, ultraviolet radiation absorbers, and the like.

     The 2000 ml beaker is heated to about 65° C. while the mixture is stirred. Mixture A is slowly poured into the mixture in the 2000 ml beaker while the Sample 1 mix is gently stirred. The heat source is removed and the Sample 1 mix is allowed to cool to room temperature, while the stirring is continued. The emulsion is reasonably stable and pourable. Sample 1 is placed in polyethylene plastic squeeze bottles for use and testing under Example 2 herein below. 
     EXAMPLE 2 
     To illustrate the utility and performance of the emulsion of Sample 1, it is compared in performance to commercially available hair conditioners. 
     Sample 2-FIN is a commercially available hair conditioner described as extra moisturizing conditioner for dry hair providing softness and body to overstyled hair. This product is further described as a dual action formula that softens and protects dry, damaged hair and replenishes and restores moisture to the hair. The ingredients of Sample 2-FIN are water, cetyl alcohol, stearyl alcohol, cyclomethicone, stearyl octyldimonium methosulfate, glycerin, sodium PCA hydrolyzed soil protein, hydroxyethylcellulose, citric acid, stearamidopropyl dimethylamine, behenamidopropyl ethyldimonium ethosulfate, amodimethicone, and tallowtrimonium chloride, nonoxynol-10, fragrance, methylchloroisothiazolinone, methylisothiazolinone, DMDM hydantoin, and disodium EDTA. 
     Sample 2-BAN is a commercially available hair conditioner described as leaving the hair naturally bright, soft and shiny while removing the yellowing from gray hair. This product is also reported to be approved for use after sodium hydroxide or no-lye relaxers. The ingredients of Sample 2-BAN are water, ceteareth-20, cetearyl alcohol, cetyl alcohol, hydrogen peroxide, pentasodium pentetate, polyquaternium-22, stearalkonium chloride and water. 
     Sample 2-WAV is a commercially available hair conditioner described as providing moisture and conditioning to dry, brittle hair aiding in revitalizing damaged, limp waves and curls and restoring tensile strength. It is reported that the hair responds with body and improved manageability. The ingredients of Sample 2-WAV are cetearyl alcohol and polysorbate 60, cetyl alcohol, collagen amino acids, acetamide MEA, silk amino acids, propylene glycol, deionized water, fragrance, glyceryl stearate SE, hydrolyzed animal protein, lecithin, methylparaben, propylparaben, and stearalkonium chloride. 
     To compare the effectiveness of the samples after the hair of a person&#39;s head has been straightened using a commercially available composition containing sodium hydroxide using standard commercially recommended procedures, each sample is applied to a quarter section of the person&#39;s head. Before testing the hair is thoroughly washed and rinsed. In the first quarter section of the head Sample 2-FIN is applied liberally to the hair and allowed to remain on the hair for three minutes. In the first section the hair is separated into bundles of about ten strands of hair using a comb. A single bundle is gripped below the middle of the length between the thumb and forefinger and the bundle is pulled slowly allowing the bundle to slide between the thumb and finger as continuous tensile force is applied. As the grip slides along the bundle toward the end breakage and the integrity of the hair strands are observed until only a single hair strand is gripped and pulled until it breaks or it is clear that the hair strand will be pulled out before it breaks. For Sample 2-FIN, as the grip slides toward the end of the bundle, the shorter strands slip out and as the number of strands reaches a few in number, some of the strands break and the last strand breaks, with the broken ends of the hairs remaining in the grip and the still attached base of the broken strands curling up. Almost all of the last strands gripped break. This same test is repeated two more times with bundles located in a different area of the quarter section with essentially identical results. 
     The above testing procedure is repeated with Samples 2-BAN and 2-WAV on different quarter sections of the person&#39;s head with very similar results. Again with each of these two Samples, there is substantial breaking of the strands including the last strand in each of the three tests. 
     Finally, the above testing procedure is repeated with Sample 1 on the final quarter section of the person&#39;s head. However, the results are dramatically different as the three bundles of strands are pulled toward the ends. In each case there is no breakage as the grip approaches the end of the bundle and in two out of three cases even the last strand do not break as they slip from the grip. 
     The entire head of hair is then washed and rinsed; and the above gripping and pulling test is repeated on bundles in each of the four quarter sections of the head. There is substantial breakage of the strands in the three sections treated with Samples 2-FIN, 2-BAN and 2-WAV, and almost no breakage in the section treated with Sample 1. This procedure is to demonstrate the effectiveness of the invention, and it should be noted that it is not necessary to wash or even rinse the hair treated according to this invention. 
     The entire head of hair is then dried; and the above gripping and pulling test is repeated on bundles in each of the four quarter sections of the head. There is substantial breakage of the strands in the three sections treated with Samples 2-FIN, 2-BAN and 2-WAV, and almost no breakage in the section treated with Sample 1. 
     The entire procedure is repeated on three different persons with the location of the samples on the heads moved clockwise a quarter turn on each person, so that each sample is tested on all different quarter sections of the head. On all the persons tested, there is substantial breakage of the strands in the three sections treated with Samples 2-FIN, 2-BAN and 2-WAV, and almost no breakage in the section treated with Sample 1. 
     The entire procedure is repeated on heads that have hair subjected to extreme curling procedures using an alkali treatment. Again the section treated with Sample 1 is superior to the sections treated with Samples 2-FIN, 2-BAN and 2-WAV.
