    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 comprising at least one lipophilic thickener and at least one silane corresponding to formula (I) below and/or oligomers thereof: R1Si(OR2)z(R3)x(OH)y (I) in which: *R1 is a linear or branched, saturated or unsaturated C1-C22 hydrocarbon-based chain, which may be substituted with a hydroxyl group, a thiol group, an aryl group (more particularly benzyl), which is substituted or unsubstituted; R1 possibly being interrupted with a heteroatom (O or S) or a carbonyl group (CO), *R2 and R3, which may be identical or different, represent a linear or branched alkyl group comprising from 1 to 6 carbon atoms, *y denotes an integer ranging from 0 to 3, and *z denotes an integer ranging from 0 to 3, and *x denotes an integer ranging from 0 to 2, * with z+x+y=3, the silane(s) of formula (I) and/or oligomers thereof being present in an active material content ranging from 2% to 20% by weight relative to the total weight of the composition. The invention also relates to a cosmetic process for making up and/or caring for keratin materials comprising a step of applying a composition according to one of the preceding claims to the said materials.

    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 cosmetic composition comprising: from 0.5% to 15% by weight, relative to the total weight of the composition of one or more fatty-chain silanes of formula (I) below and/or oligomers thereof: R1Si(OR2)z(R3)x(OH)y (I) in which formula (I): R1 represents a linear or branched alkyl or alkenyl group comprising from 7 to 18 carbon atoms, R2 and R3, which may be identical or different, represent a linear or branched alkyl group comprising from 1 to 6 carbon atoms, y denotes an integer ranging from 0 to 3, z denotes an integer ranging from 0 to 3, preferentially from 1 to 3 and better still equal to 3, and x denotes an integer ranging from 0 to 2, with z+x+y=3, one or more fixing polymers chosen from anionic, amphoteric and non-ionic fixing polymers. The invention also relates to the use of said composition for shaping and/or fixing keratin fibres, such as human keratin fibres and in particular the hair, and also to a cosmetic treatment process for keratin fibres using such a composition.
