GLUCURONOLACTONE DERIVATIVES AS SELF-TANNING SUBSTANCES

摘要

The invention relates to the use of specific glucuronolactone derivatives as self-tanning substances, as tanning enhancers for dihydroxyacetone or for a mixture of self-tanning substances comprising dihydroxyacetone, for modulation of the hue achieved in the case of tanning with dihydroxyacetone or by the mixture or preparation comprising dihydroxyacetone, as contrast-reduction agents or for colouring keratin-containing fibres, and to preparations or compositions for colouring keratin-containing fibres comprising these specific glucuronolactone derivatives.

1. A method for tanning skin, comprising tanning said skin by administering these to an effective amount of at least one compound of the formula IwhereR1 and R2 each, independently of one another, denotea straight-chain or branched alkyl group having 1 to 30 C atoms,andeither R1 or R2 may denote H,orR1 and R2 together form an unsubstituted or substituted five-membered ring, which may be substituteda) by at least one straight-chain or branched alkyl group having 1 to 30 C atoms and/orb) by at least one aryl group having 6 to 12 C atoms,where the aryl group having 6 to 12 C atoms may be substituted by alkyl, OH, Oalkyl, NH2, NHalkyl, N(alkyl)2, C(O)alkyl, O—C(O)alkyl and/or C(O)Oalkyl,R3 denotes a straight-chain or branched alkyl group having 1 to 30 C atomsoran aryl group having 6 to 12 C atoms, where the aryl group having 6 to 12 C atoms may be substituted by alkyl, vinyl, OH, Oalkyl, NH2, NHalkyl, N(alkyl)2, C(O)alkyl, O—C(O)alkyl and/or C(O)Oalkyl ora straight-chain or branched alkenyl group having 2 to 30 C atoms, which may be substituted by an aryl group having 6 to 12 C atoms, where the aryl group having 6 to 12 C atoms may be substituted by alkyl, OH, Oalkyl, NH2, NHalkyl, N(alkyl)2, C(O)alkyl, O—C(O)alkyl and/or C(O)Oalkyl, andalkyl denotes a straight-chain or branched alkyl group having 1 to 30 C atoms,and/or salts, tautomers, stereoisomers and/or solvates thereof, including mixtures thereof in all ratios, as self-tanning substance.
