The preparation for permanently deforming hair has a pH of 6.5 to 9.5 and contains, as keratin-reducing agent, a 2-mercaptopropion-amide of the formula (I): in which Rand R, independently of one another, represent H, a linear or branched alkylaminoalkyl group with 2 to 8 carbon atoms, or a morpholinoalkyl group with 2 to 3 carbon atoms in the alkyl portion of the morpholinoalkyl group, with the proviso that Rand Rare not simultaneously H, or that Rand R, together with the nitrogen atom, form a five-or six-membered heterocyclic ring, which optionally contain an additional N or O and are optionally substituted with one or two OH and/or methyl groups.

The composition for hardening, strengthening and restructuring keratin-containing materials and/or for increasing the volume of keratin-containing fibers, such as hair, contains from 0.3 to 50.0% by weight of one or more reductones, each having a &mdash;(HO)C&boxH;C(OH)&mdash; group. The reductone ingredient is preferably ascorbic or isoascorbic acid, a salt of ascorbic or isoascorbic acid, such as an alkali metal or alkaline earth metal salt, an ester of ascorbic or isoascorbic acid, 6-O-palmitoyl ascorbate, ascorbyl phosphate, 2,3-dihydroxy-2-propenal and hydroxypropanedial. A method of treating keratin-containing materials or fibers to harden, strengthen and restructure keratin-containing materials and/or to increase the volume of the keratin-containing fibers by applying this composition and allowing it to act is described. A method of pre-treating keratin-containing material that is to be subjected to a chemical or physical treatment, such as dyeing or permanent shaping is also described.

The permanent shaping composition for permanent shaping of hair includes from 2 to 25 percent by weight of a conventional keratin-reducing compound and from 0.02 to 5 percent by weight of certain diquaternary polysiloxanes. The permanent wave-pretreatment composition includes from 0.02 to 5 percent by weight of the diquaternary polysiloxanes. The permanent shaping composition advantageously includes mercaptocarbonic acid reducing agents and has a pH of from 6 to 10 and may include conventional cosmetic additives. Methods for using the permanent shaping composition and the permanent wave-pretreatment composition are described which provide a more uniform permanant wave from the hair roots to the hair tips.

Methods and compositions for permanent shaping of hair

The new keratin-reducing substances useful in compositions for permanent shaping of hair are glyceryl esters of cysteine, especially the monoglyceryl esters. As monoglyceryl esters of cysteine 2-amino-3-mercaptopropionic acid-(2',3'-dihydroxypropyl)ester and 2-amino-3-mercaptopropionic acid-(1',3'-dihydroxyisopropyl)ester are particularly preferred. A preferred embodiment of the compositions for permanent shaping of hair consists of a ready-to-use mixture of a water-free component including at least one glyceryl ester of cysteine and at least one other component which is kept physically separately from the water-free component until the mixture is prepared. The compositions also can include other conventional ingredients normally used in permanent shaping compositions such as surfactants and thickeners. The compositions have a preferred pH range of 6.0 to 8.5 and contain from 8 to 28 percent by weight of the glyceryl esters of cysteine.

A cosmetic composition is disclosed for the treatment of hair or skin, based upon 0.05 to 10% by weight of chitosan, and characterized by a content of 0.05 to 20% by weight of an ampholytic copolymerizate of formula (I) ##STR1## wherein m=0.5 to 0.9, n=0.1 to 0.5, m+n=1 and p being such that the ampholytic copolymerizate has a molecular weight of from 1,000 to 3,000,000. wherein m=0.1 to 0.9 and n=0.5 to 0.9. The composition provides clear, smooth films, which are neither sticky in moist climate, nor brittle in dry climate. Also disclosed are new chitosan/polyampholyte salts, obtained by reaction of chitosan with an ampholytic copolymerizate of formula (I).
