## Abstract

A colored fragrancing composition is provided that comprises, in a cosmetically acceptable medium: a) at least 2% by weight of a fragrancing substance relative to the total weight of the composition; b) at least one derivative of benzylidene camphor containing a sulphonic function or a benzotriazole silicone of particular formula (1) that will be defined below in detail; c) at least one dye that is soluble in said medium; said composition not containing an alkyl β,β′-diphenylacrylate compound or an alkyl α-cyano-β,β′-diphenylacrylate compound. Also provided is a cosmetic method for fragrancing human keratin substances and in particular the skin, lips and integuments, comprising the application to the keratin substances of the composition defined previously.

## Claims

### Claim 1

Coloured fragrancing composition comprising, in a cosmetically acceptable medium:
a) at least 2% by weight of a fragrancing substance relative to the total weight of the composition;
b) at least one derivative of benzylidene camphor with a sulphonic function which is benzene-1,4-di(3-methylidene-10-camphorsulphonic) acid, and/or one of its salts and their isomeric forms of formula (IX) below:
in which F denotes a hydrogen atom, an alkali metal or an NH(R3)3+radical in which the R3 radicals, which may be identical or different, denote a hydrogen atom, a C1-C4 alkyl or hydroxyalkyl radical or a group Mn+/n, Mn+denoting a multivalent metal cation in which n is equal to 2, 3 or 4,
or a benzotriazole silicone of following formula (7):
with 0≦r≦10,
1≦s≦10,
and where E represents the divalent radical:
c) at least one dye that is soluble in said medium; said composition not containing an alkyl β,β′-diphenylacylate or alkyl α-cyano-β,β′-diphenylacrylate compound; and whereby said composition has improved stability of colour and organoleptic properties due to the at least one derivative of benzylidene camphor or benzotriazole silicone.
