The invention describes a cosmetic composition formulated to provide artificial tanning of the skin and containing a tanning agent and a derivative of an amino-substituted 2-hydroxybenzophenone. <??>The cosmetic composition formulated to provide artificial tanning of the skin contains: <??>(i) a tanning agent; and <??>(ii) derivative of an amino-substituted 2-hydroxybenzophenone of formula (I). <??>R<1>, R<2> = 1 - 20C alkyl, 2 - 10C alkenyl or 3 - 10C cycloalkyl or cycloalkenyl (R<1> and R<2> may form a 5 - 6 membered ring with the N atom); <??>R<3>, R<4> = 1 - 20C alkyl, 2 - 10C alkenyl, 3 - 10C cycloalkyl or cycloalkenyl, 1 - 12C alkoxy, 1 - 20C alkoxycarbonyl, 1 - 12C alkyl or dialkyl-amino, aryl or heteroaryl, optionally substituted, or carboxylate, sulfonate or ammonium; <??>X = H, COOR5 or CONR<6>R<7>; <??>R<5>, R<6>, R<7> = H, 1 - 20C alkyl, 2 - 10C alkenyl, 3 - 10C cycloalkyl or cycloalkenyl, a group -(YO)o-Z or aryl; <??>Y = -(CH2)2-, -(CH2)3 -(CH2)4 or -CHCH3-CH2-; <??>Z = -CH2CH3, -CH2CH2CH3, -CH2CH2CH2CH3 or -CH(CH3)CH3; <??>m = 0 - 3; <??>n = 0 - 3; and <??>o = 1 - 2. <??>Independent claims are also included for the use of the composition and process of artificial tanning.
