Abstract

The present invention relates to a cosmetic and/or dermatological composition comprising, in a physiologically acceptable medium containing at least one oil:

(a) at least one compound of general formula (Ia):

and
(b) an efficient amount of at least one solvent chosen from:

• • (i) isononyl isononanoate;
  • (ii) dimethyl isosorbide;
  • (iii) the amino acid esters of formula (II):

R′₁(CO)N(R′₂)CH(R′₃)(CH₂)_n(CO)OR′₄  (II)

• • (iv) and a mixture thereof.

Claims
