Abstract: The present invention relates to a composition for reshaping keratin fibers with heat, comprising: (a) at least one organic alkaline agent having a pKa value of from 8.0 to 13.5; and (b) at least one polymeric thickener, (c) at least one organic acidic agent having pKa value of less than 3.5, and/or (d) at least one alkaline agent; wherein the composition has a pH of from 8.0 to 12, preferably from 8.5 to 11.5, and more preferably from 9.0 to 11.0. The composition according to the present invention is preferably a cosmetic composition, for keratin fibers, such as hair, and can be used for a process for reshaping the keratin fibers with heat. The composition according to the present invention can provide the keratin fibers with a sufficient reshaping efficiency such as strong wave intensity of the curled keratin fibers and good usability.

Abstract: The present invention relates to a composition for reshaping keratin fibers, preferably the hair, having a specific range of a pH and including at least one specific active compound in an amount of 8% by weight or more relative to the total weight of the composition. The composition according to the present invention is preferably a cosmetic composition, for keratin fibers, such as hair, and can be used for a process for reshaping the keratin fibers with heat. The process according to the present invention can be used to deform or reshape keratin fibers, preferably hair, and can provide the keratin fibers with sufficient reshaping efficiency such as strong wave intensity of the curled keratin fibers and excellent hair conditioning effects (less damage to the keratin fibers), in a relatively short period of time as compared to a conventional process which uses a reducing agent and an oxidizing agent.

Abstract: The present invention relates to a process for reshaping keratin fibers, preferably hair, comprising the steps of: (i) applying onto the keratin fibers a composition comprising (a) at least one diol selected from C4-5 diols, wherein the composition has a pH of from 8.0 to 13.5, preferably from 8.5 to 12.0, and more preferably from 9.0 to 11.0; (ii) heating the keratin fibers; and (iii) optionally rinsing and/or drying the keratin fibers. The present invention can reshape keratin fibers without reducing and oxidizing the keratin fibers, and can provide superior reshaping efficiency, such as strong wave intensity and many curls.
