Abstract

The present invention relates to the use of an α,ω-substituted oxyalkylenated silicone, in particular of formula (I) below: 1 in which: R=—(CH2)pO—(C2H4O)x(C3H6O)yR1 where: R1 represents H, CH3 or CH2CH3, p is an integer ranging from 1 to 5, x ranges from 1 to 100 and y ranges from 0 to 50, it being possible for the units (C2H4O) and (C3H6O) to be distributed randomly or in blocks, the radicals R2 represent a C1-C3 alkyl radical or a phenyl radical, and 5≦m≦300, in a composition for cosmetic, pharmaceutical, dermatological or hygiene use, in order to limit, reduce and/or eliminate the transfer and/or migration of the said composition. The invention also relates to a stable water-in-oil emulsion for cosmetic, pharmaceutical, dermatological or hygiene use, comprising an aqueous phase and a fatty phase comprising a silicone oil, characterized in that it comprises at least one α,ω-substituted oxyalkylenated silicone chosen from those defined above in combination with dyestuffs.
