Abstract

Compositions are provided for lightening skin and toning down pigment disorders which include, as active substances, at least one of the compounds of the general formula (I) and/or salts thereof in which R 1 is H, alkyl, hydroxyalkyl, or a carboxyalkyl radical having 2 to 30 carbon atoms; and R 2 is H or a hydrocarbon radical having 1 to 30 carbon atoms which may be branched or unbranched and may or may not contain double bonds.

Claims (24)

1 . A method for lightening skin and toning down pigment disorders which comprises applying to skin an effective amount of a composition that comprises, as a skin lightening active substance, at least one compound of formula (I) and/or salts thereof

in which

R 1 is H, alkyl, hydroxyalkyl, or a carboxyalkyl radical having 2 to 30 carbon atoms; and

R 2 is H or a hydrocarbon radical having 1 to 30 carbon atoms.

2 . The method of claim 1 wherein R 1 and/or R 2 have 2 to 20 carbon atoms.

3 . The method of claim 1 wherein R 1 and/or R 2 are hydrogen.

4 . The method of claim 1 wherein 0.05 to 10.0% by weight of at least one of the compounds of the general formula (I) is present as the active substance.

5 . The method of claim 1 wherein 0.2 to 5.0% by weight of at least one of the compounds of the general formula (I) is present as the active substance.

6 . The method of claim 1 wherein R 2 is a branched hydrocarbon radical.

7 . The method of claim 1 wherein R 2 is a hydrocarbon radical that contains double bonds.

8 . The method of claim 1 wherein the composition further comprises:

a) 0.05 to 10 parts by weight of at least one of the compounds of the general formula (I), and

b) 1 to 10 parts by weight of at least one surfactant selected from the group consisting of nonionic, amphoteric, zwitterionic, and ionic surfactants.

9 . The method of claim 8 wherein the composition further comprises:

c) 2 to 10 parts by weight of vegetable, mineral, or ester oils,

d) 1 to 5 parts by weight of bodying agents,

e) 0.5 to 5.0 parts by weight of fragrances, dyes, plant extracts, preservatives, and

f) add 100% with water.

10 . The method of claim 1 wherein the composition comprises a cosmetic formulation.

11 . The method of claim 1 wherein the composition comprises a dermatological formulation.

12 . A method for lightening skin and toning down pigment disorders, which comprises applying to skin an effective amount of a composition that comprises, as a sole skin lightening active substance, at least one compound of formula (I) and/or salts thereof

in which

R 1 is H, alkyl, hydroxyalkyl, or a carboxyalkyl radical having 2 to 30 carbon atoms; and

R 2 is H or a hydrocarbon radical having 1 to 30 carbon atoms.
