ABSTRACT:
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.
U.S. Pat. No. 5,415,855 to Critchley, et al, describes a cosmetic composition for topical application to human skin and hair or nails. A wash list of emollients is provided that includes cetyl alcohol, stearic acid, isopropyl and butyl myristate, lanolin, mineral oil and many others. Triton X-100 is listed as one of the emulsifiers. The examples in this patent disclose emollients used in relatively small quantities.
U.S. Pat. No. 5,378,455 to Kealey, et al, describes cosmetic compositions for topical application to human skin and hair for inhibiting hair growth naming various compounds in multiple long all inclusive lists including small quantities of emollients.
U.S. Pat. No. 4,999,195 to Hayes describes personal care compositions for topical application to human skin and hair containing bioemulsifiers including a shampoo with less than 5% emollient and cleansing cream and lotion compositions with less than 15% emollients. U.S. Pat. No. 4,870,010 to Hayes is a similar disclosure.
U.S. Pat. No. 5,342,611 to Komori, et al describes hair cleansing compositions with a claimed range of 20% to 98% of a liquid oil. Specific shampoo compositions includes 20% jojoba oil and a dandruff remover contains 40% olive oil.
U.S. Pat. No. 5,034,219 to Deshpande, et al describes hair conditioner compositions containing less than 15% emollients.
U.S. Pat. No. 5,725,875 to Noll et al. describes protective skin cream compositions, which contain, among many other possible components, nonoxynol-9, identified as Triton AN-101, and emollients, such as glycerin, sorbitol and propyl glycol.
U.S. Pat. No. 5,817,155 to Yasuda et al. describes an emulsion for reducing dripping during the dying of hair. In the “wash lists” of polar oils included in the oil phase of certain compositions, ester oils are listed including alkyl myristates, such as isopropyl myristate, octyldodecyl myristate and myristyl myristate are listed together with dozens of other compounds, and noting that said oils are not preferred. The oils are found in some examples in five percent quantities.
U.S. Pat. No. 5,888,489 to Von Mallek describes conditioning shampoo compositions, including a wash list of emollients, that includes fatty acid esters, such as isopropyl myristate. A disclosure indicates that an emollient is used in 0.5 to 2.0% by weight quantities.
U.S. Pat. No. 5,968,530 to Arquette describes emollient compositions for skin care, preferably containing jojoba oil, wash listing some eighty possible cosmetic uses including hair preparations, specifically hair conditioner, hair spray, hair straighteners, permanent waves, rinses, and shampoos. Specific examples in the patent did not include any hair preparations.
U.S. Pat. No. 5,935,560 to Seper et al. describes compositions and methods to impart durable conditioning properties to hair, specifically using a thiol-functional silicone. Water soluble conditioning agents are shown in long wash list that includes isopropyl myristate and other emollients.
U.S. Pat. No. 5,641,480 to Vermeer describes compositions with heteroatom containing alkyl aldonamide compounds for hair care, especially conditioners, shampoos, conditioning shampoos, and anti dandruff shampoos. A very long wash list of surfactants including nonionic surfactants lists Triton X-100 as the condensation product of octylphenol with about 9 to 10 moles of ethylene oxide. A wash list of hair conditioning agents includes isopropyl myristate and two of 135 examples include mineral oil. None of the examples contain even two of the three compounds.
U.S. Pat. No. 5,709,847 to Bissett et al. describes sun screen skin care compositions containing a radical scavenging compound and an anti inflammatory agent to protect from sun irradiation. The preparations include a large amount of emollient and a wash list includes alkenyl esters of fatty acids with 10 to 20 carbon atoms, lanolin, and wax esters such as myristyl myristate. A wash list of emulsifiers includes a wash list of nonionic emulsifiers and examples contain glycerin and mineral oil.
U.S. Pat. No. 5,639,459 to Bouras describes hair and scalp conditioner compositions containing an oxalate in a paraffin based ointment.
U.S. Pat. No. 5,618,523 to Zysman et al. describes hair and scalp conditioner compositions containing ceramides with a wash list of adjuvants that includes propylene glycol, mineral oil, lanolin and emulsifiers with the fatty phase of the emulsion being 5 to 60 percent of the total weight.
U.S. Pat. No. 5,639,449 to Syed et al. describes a hair strengthening composition for hair that has been exposed to relaxer, the composition containing a water-dispersible polyquaternary ammonium cationic polymer that is applied after a hair swelling component has been added to the hair. Relaxer compositions examples contain up to 18% mineral oil and 12% petrolatum.
None of the prior art compositions and methods teach the present invention or attain the objects provided herein below
SUMMARY OF INVENTION
It is an object of the present invention to provide a composition and a method of use that substantially reduces the incidence to split ends of excessively curly hair that has been subjected to a straightening process or straight hair that has been to a curling process.
It is a further object of the present invention to provide a composition and a method of use that substantially increases the tensile strength and greatly reduces the breakage of excessively curly hair that has been subjected to a straightening process, both immediately and for extended periods of time after treatment.
It is an additional object of the present invention to provide a composition and a method of use that substantially improves the condition of excessively curly hair that has been subjected to a straightening process without introducing chemicals that cause side effects to the health of the hair and scalp.
It is a further object of the present invention to provide a method of producing and applying a composition that, when applied to excessively curly hair that has been subjected to a straightening process, substantially improves the health of the hair, including increasing the elasticity of the hair shaft and enhancing the color of the hair, both indicating restructuring of the hair shaft.
It is an additional object of the present invention to provide a method of producing and applying a composition that, when applied to excessively curly hair that has been subjected to a straightening process, improves the health of the hairline allowing it a chance to develop and avoid breaking off during subsequent washing with soap and with wash cloths.
It is a further object of the present invention to provide a method of producing a composition that, when applied to excessively curly hair that has been subjected to a straightening process, allows the person to go longer without the need of using conditioners.
It is an additional
