Title: CONCENTRATE FOR KERATIN FIBER TREATMENT COMPOSITIONS
Abstract:
1 Concentrate for Keratin Fiber Treatment Compositions The present invention is a versatile cosmetic composition in form of a liquid concentrate which is useful as additive or ingredient for conventional keratin fiber treatment compositions. It can be used as ready to use additive to conventional yet damaging treatments to which it is added at the time of the treatment. Such treatments are typically hair bleaches, hair colorants or permanent wave compositions. The concentrate comprises a combination of ingredients intended to reduce damage during treatments and/or to prevent undesired deposits on fibers. Such a composition comprises at least a thiol and a polymer or copolymer comprising cystine units. Such a composition is further useful as additive or ingredient for a keratin fiber caring or repairing composition to reduce damage caused by prior treatments and/or reduce undesired deposits on fibers by using the concentrate directly after treatments causing such deposits.
