Stable cosmetic composition containing a monoglyceride, a tartaric ester of monoglyceride, and a coated filler

Abstract

The invention relates to a composition, especially a cosmetic composition, characterized in that it comprises at least one monoglyceride and at least one tartaric ester of monoglyceride, and at least one coated pigment and/or mineral filler. The invention also relates to the use of a coated pigment and/or coated mineral filler for improving the stability of a composition, especially a cosmetic composition comprising at least one monoglyceride and at least one diacetyl tartaric ester of monoglyceride. The invention further relates to a cosmetic treatment method that implements the composition of the invention

 triisostearyl isopropyl titanate; isostearyl sebacate; plant or animal natural waxes, synthetic waxes polar; fatty esters; fatty alcohols; phospholipids, and mixtures thereof.   
     
     
         9 . Composition, according to  claim 1 , wherein the composition comprises a pigment and/or mineral filler content coated from 0.1% to 4% by mass based on the total mass of said composition. 
     
     
         10 . Composition according to  claim 1 , wherein the treatment agent represents from 0.1 to 50% by mass of the total mass of the coated pigment and the coated mineral filler. 
     
     
         11 . Composition according to  claim 1  which comprises a least one sequestering agent. 
     
     
         12 . Composition according to  claim 1  which comprises a least one sequestering agent from among the following or any combination thereof: ethylene diamine tetraacetic acid (EDTA), glucono delta-lactone, sodium gluconate, potassium and/or calcium; citric acid, phosphoric acid, tartaric acid, potassium bitartrate, sodium acetate, and sorbitol. 
     
     
         13 . Composition, according to  claim 1 , wherein the composition comprises a sequestering agent from 0.01% to 1% by mass based on the total mass of said composition. 
     
     
         14 . Composition, according to  claim 1  which comprises a lipogel phase. 
     
     
         15 . Use of at least one coated pigment and/or at least one coated mineral filler, optionally in combination with at least one sequestering agent, for improving the stability of a composition comprising at least one monoglyceride and at least one diacetyl tartaric ester of monoglyceride. 
     
     
         16 . Cosmetic treatment method, which comprises applying of a composition such as defined according to  claim 1  on an area of skin, in particular to limit the gloss or shiny appearance of the skin at the area of application, especially in a tropical climate.
