Oil-in-water emulsion having improved sensory properties

Abstract

An oil-in-water emulsion includes, for 100 wt % thereof: a) 0.1 to 10 wt % of an emulsifying system including, for 100 wt % thereof: (i) 5 to 95 wt % of the mixture of the reaction products of a reducing sugar and 1,12-octadecanediol essentially consisting of hydroxyl-octadecyl polyglycosides of formula (I): HO—R—O-(G) n -H (I) and of polyglycosyl octadecyl polyglycosides of formula (II): H-(G) m -O—R—O-(G) p -H (II), where, in formulas (I) and (II), G is the remainder of the reducing sugar and R is the divalent radical octadecane-diyl-1,12, and where n, m and p, identical or different, each are, independently of each other, a decimal number between 1 and 5; (ii) 95 to 5 wt % of 1,12-octadecanediol; b) 0.01 to 5 wt % of at least one thickening and/or gelling agent; c) 10 to 50 wt % of an oil phase; and d) 89.89 to 35 wt % of an aqueous phase.

1 . A method for artificial bronzing and/or tanning the skin of an individual, which comprises applying to the skin of said individual an effective amount of a composition that is in the form of an oil-in-water emulsion comprising per 100% of its weight:
 a)—From 0.1 to 10 wt.% of an emulsifying system (A) consisting per 100% of its weight of:   (i) from 5 to 95 wt. % of the mixture of reaction products of a reducing sugar and of 1,12-octadecanediol constituted essentially of hydroxyoctadecyl polyglycosides of formula (I):
   HO—R—O-(G) n -H  (I)
 
   and of polyglycosyloctadecyl polyglycosides of formula (II):
   H-(G) m -O—R—O-(G) p -H  (II),
 
   where, in formulas (I) and (II), G represents the residue of said reducing sugar and R represents the 1,12-octadecane-diyl divalent radical and where n, m and p, which may be identical or different, each represent, independently of one another, a decimal number between 1 and 5;   (ii) from 95 to 5 wt. % of 1,12-octadecanediol;   b) from 0.01 to 5 wt. % of at least one thickener and/or gelling agent selected from thickeners and/or gelling agents of natural origin;   c) from 10 to 50 wt. % of a fatty phase (P2) consisting of one or more vegetable oils based on monoglycerides and/or diglycerides and/or triglycerides;   d) from 89.89 to 35 wt. % of a cosmetically acceptable aqueous phase (P1); and   e) from 0.5 to 10 wt. % of dihydroxyacetone.   
     
     
         2 . A method of cosmetic treatment for artificial bronzing and/or tanning of the skin, comprising applying a composition that is in the form of an oil-in-water emulsion comprising per 100% of its weight:
 a)—From 0.1 to 10 wt.% of an emulsifying system (A) consisting per 100% of its weight of:   (i) from 5 to 95 wt. % of the mixture of reaction products of a reducing sugar and of 1,12-octadecanediol constituted essentially of hydroxyoctadecyl polyglycosides of formula (I):
   HO—R—O-(G) n -H  (I)
 
   and of polyglycosyloctadecyl polyglycosides of formula (II):
   H-(G) m -O—R—O-(G) p -H  (II),
 
   where, in formulas (I) and (II), G represents the residue of said reducing sugar and R represents the 1,12-octadecane-diyl divalent radical and where n, m and p, which may be identical or different, each represent, independently of one another, a decimal number between 1 and 5;   (ii) from 95 to 5 wt. % of 1,12-octadecanediol;   b) from 0.01 to 5 wt. % of at least one thickener and/or gelling agent selected from thickeners and/or gelling agents of natural origin;   c) from 10 to 50 wt. % of a fatty phase (P2) consisting of one or more vegetable oils based on monoglycerides and/or diglycerides and/or triglycerides;   d) from 89.89 to 35 wt. % of a cosmetically acceptable aqueous phase (P1); and   e) from 0.5 to 10 wt. % of dihydroxyacetone.
