PREPARATION OF A PULVERULENT/PASTY COMPOSITION COMPRISING A SILICONE ELASTOMER GEL, SOLID PARTICLES AND A BINDER PHASE, AND LIP TREATMENT PROCESS

摘要

The present invention relates to a process for preparing an anhydrous composition in powder form or in paste form, in which the following steps are performed:
from 30% to 65% by weight, relative to the weight of the composition, of organic, mineral or composite solid particles, and also mixtures thereof, are prepared,10% to 40% by weight, relative to the weight of the composition, of a mixture comprising at least one organopolysiloxane elastomer conveyed in at least a first silicone or hydrocarbon-based non-volatile oil is prepared,10% to 45% by weight, relative to the weight of the composition, of an organic binder phase comprising at least a second hydrocarbon-based or silicone non-volatile oil, identical to or different from the first oil, is prepared; at least one pasty compound having a content of between 5% and 25% by weight, relative to the weight of the composition, optionally at least one wax and optionally at least one volatile oil; the wax content not exceeding 5% by weight, relative to the weight of the composition,the binder phase and said conveyed organopolysiloxane elastomer are introduced into the solid particles with stirring; the conveyed organopolysiloxane elastomer being introduced with the binder phase or separately therefrom.;The invention also relates to a process for making up and/or caring for the lips, in which the abovementioned composition is applied.

1. A process for preparing an anhydrous composition in powder form or in paste form, the process comprising:
preparing from 30% to 65% by weight, relative to the weight of the composition, of organic, mineral or composite solid particles, or any mixture thereof; preparing 10% to 40% by weight, relative to the weight of the composition, of a mixture comprising at least one organopolysiloxane elastomer conveyed in at least a first silicone or hydrocarbon-based non-volatile oil; preparing 10% to 45% by weight, relative to the weight of the composition, of an organic binder phase comprising at least a second hydrocarbon-based or silicone non-volatile oil, identical to or different from the first oil, at least one pasty compound having a content of between 5% and 25% by weight, relative to the weight of the composition, optionally at least one wax and optionally at least one volatile oil, the wax content not exceeding 5% by weight, relative to the weight of the composition; introducing the binder phase and said conveyed organopolysiloxane elastomer into the solid particles with stirring, wherein the conveyed organopolysiloxane elastomer is introduced with the binder phase or separately therefrom.
