Novel cosmetic compositions for artificial skin tanning, including a cosmetically acceptable carrier such as a water-in-silicone carrier containing dihydroxyacetone as the tanning agent, are disclosed. The compositions further include a mono- or dihydric alcohol and a silicone emulsifier consisting of a polydimethylsiloxane having one of formulae (I) and (II), wherein 1 <= a <= 500 (where a is an integer), 1 <= b <= 100 (where b is an integer), and R is a radical -C¿n?H¿2n?-(-OC¿2?H¿4?)¿x?-(-OC¿3?H¿6?)¿y?-O-R', where R' is H or a straight or branched C¿1-12? alkyl radical, and O <= x <= 50 (where x is an integer), O <= y <= 50 (where y is an integer), x + y >= 1, and 2 <= n <= 12 (where n is an integer). Said compositions are useful for artificially tanning and/or darkening skin.

La présente invention concerne de nouvelles compositions cosmétiques destinées au bronzage artificiel de la peau, comprenant, dans un support cosmétiquement acceptable de type eau-dans-silicone, de la DHA à titre d'agent autobronzant, caractérisées en ce qu'elles comprennent en outre un alcool mono ou dihydrique et un émulsionnant siliconé constitué d'un polydiméthylsiloxane de formule (I ou II), dans lesquelles 1 <= a <= 500 (a étant un nombre entier, 1 <= b <= 100 (b étant un nombre entier), R représente un radical -CnH2n-(-OC2H4)x-(-OC3H6)y- O-R', dans lequel R' représente H ou un radical alkyle linéaire ou ramifié en C1-C12 et 0 <= x <= 50 (x étant un nombre entier), 0 <= y <= 50 (y étant un nombre entier), x+y >= 1, 2 <= n <= 12 (n étant un nombre entier). Application au bronzage et/ou brunissage artificiels de la peau.
