AI Technical Summary

Technical Problem

Existing cosmetic compositions, particularly water-in-oil emulsions, face challenges in stabilization and environmental compatibility due to the use of silicones, while consumers seek silicone-free formulations with good coverage, sensory properties, and environmental friendliness.

Method used

A silicone-free water-in-oil emulsion comprising a continuous oily phase with C12-C22 dialkyl carbonate, C8-C10 carboxylic acid esters from coconut oil, volatile hydrocarbon oil, and a non-ionic emulsifying surfactant polyethylene glycol di-polyhydroxystearate, along with an aqueous phase and powdered coloring materials, to achieve stable and homogeneous application.

Benefits of technology

The composition provides stable, silicone-free emulsions with good coverage, ease of application, non-greasy feel, and improved environmental compatibility, offering a homogeneous and pleasant user experience.

Abstract

Title: Emulsion with a dialkyl carbonate, coconut oil esters, a hydrocarbon volatile oil and a polyoxyethylenated fatty acid and glycol ester polymer. This application relates to a silicone-free water / oil emulsion comprising at least A) a continuous oily phase comprising: i) at least one C12-C22 dialkyl carbonate; and ii) at least one mixture of C8-C10 carboxylic acid(s) esters and fatty alcohols derived from coconut oil; and iii) at least one hydrocarbon volatile oil; and B) an aqueous phase dispersed in said oily phase; C) at least one non-ionic emulsifying surfactant of the type polyoxyethylenated fatty acid and glycol ester polymer.The invention also relates to a method of coating keratinous materials, more particularly for makeup and / or care of keratinous materials, such as skin, characterized in that it comprises the application on keratinous materials of a composition as defined above.
