Abstract
There are provided compositions for improving the washfastness and color intensity of colored fibers, especially keratin fibers, which comprise a) at least one sugar surfactant chosen from the group consisting of alkyl and alkenyl oligoglycosides or fatty acid N-alkylpolyhydroxyalkylamides and b) at least one fatty acid partial glyceride.
Claims20
A method of increasing the washfastness and color intensity of colored fibers which comprises applying to said fibers a composition comprising
- a) at least one sugar surfactant selected from the group consisting of alkyl and alkenyl oligoglycosides and fatty acid N-alkylpolyhydroxyalkylamides;
- b) at least one fatty acid partial glyceride of the Formula IV:
- wherein at least one of R4, R5, and R6, is a C6-22 acyl radical, at least one of R4, R5, and R6 is H, and the remaining group is H or C6-22 acyl radical, and the sum (m+n+q) is 0;
- and
- c) a surfactant.
A method of increasing the washfastness and color intensity of colored fibers, comprising:
- applying a composition comprising at least one sugar surfactant selected from the group consisting of alkyl and alkenyl oligoglycosides and fatty acid N-alkylpolyhydroxyalkylamides and at least one fatty acid partial glyceride to said fibers;
- and
- allowing the composition to remain on the fibers for longer than one hour.
A method of increasing the washfastness and color intensity of colored fibers, comprising:
- applying to said fibers a composition comprising
- at least one alkyl oligoglycoside, alkenyl oligoglycoside, or fatty acid N-alkylpolyhydroxyalkylamide;
- and
- oleic acid monoglyceride.
