A composition for treating or caring keratin fibers comprising:
- (a) at least one negatively charged amino acid or a derivative thereof in an amount of at least about 1% by weight;
- (b) at least one positively charged amino acid or a derivative thereof in an amount of at least about 1% by weight;
- (c) at least one silicone copolymer;
- and
- (d) at least one nonionic emulsifier;
- wherein all amounts are relative to the total weight of the composition;
- wherein the composition is in the form of an emulsion.
A method of treating or caring for keratin fibers, comprising:
- (1) applying to the keratin fibers a comprising:
- (a) at least one negatively charged amino acid or a derivative thereof in an amount of at least about 1% by weight;
- (b) at least one positively charged amino acid or a derivative thereof in an amount of at least about 1% by weight;
- (c) at least one silicone copolymer;
- and
- (d) at least one nonionic emulsifier;
- wherein all amounts are relative to the total weight of the composition;
- and
- (2) optionally rinsing the composition from the keratin fibers.
A packaging system comprising a container containing a composition for treating keratin fibers, the composition being in the form of an emulsion and comprising:
- (a) at least one negatively charged amino acid or a derivative thereof in an amount of at least about 1% by weight;
- (b) at least one positively charged amino acid or a derivative thereof in an amount of at least about 1% by weight;
- (c) at least one silicone copolymer;
- and
- (d) at least one nonionic emulsifier;
- wherein all amounts are relative to the total weight of the composition.
A kit comprising:
- a first container comprising a first composition for treating keratin fibers, the first composition being in the form of an emulsion and comprising:
- (a) at least one negatively charged amino acid or a derivative thereof in an amount of at least about 1% by weight;
- (b) at least one positively charged amino acid or a derivative thereof in an amount of at least about 1% by weight;
- (c) at least one silicone copolymer;
- and
- (d) at least one nonionic emulsifier;
- wherein all amounts are relative to the total weight of the composition.
