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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to novel compositions in the form of oil-in-water emulsions, and the methods of preparation thereof.BACKGROUND OF THE INVENTION[0002]The invention preferably finds application in the cosmetic and dermocosmetic field, in the dermopharmaceutical and pharmaceutical field, notably for use in the care, protection and cleaning of the skin, hair and scalp, but also in the field of the textile industry, for example for the treatment of woven or knitted, synthetic or natural textile fibers, or in the field of the papermaking industry, for example for the manufacture of paper for sanitary or household use.[0003]In the development of formulations intended for treating and / or protecting the skin and / or the mucous membranes and / or the scalp, and generally for body care products, the sensory properties constitute an important criterion for their commercial success. In fact, the end user's choice is based as much on sensory criteria and cri...

AI Technical Summary

Benefits of technology

The patent describes the development of new skincare products that use natural ingredients and have improved sensory properties. They should be consistent and easy to apply, have a softness index, and be non-soaping during use. These products should be evaluated and found satisfactory by a trained panel of people.

Problems solved by technology

However, when cosmetic formulations comprising fats of vegetable origin and / or thickeners and / or gelling agents and / or stabilizers of natural origin, and / or emulsifiers derived from sugars and fatty alcohols of vegetable origin, and / or emulsifiers derived from sugars and fatty acid of vegetable origin, and / or emulsifiers based on esters of fatty acids of vegetable origin and of glycerol, are applied on the skin, the sensory results are unsatisfactory.

However, these technical solutions have the drawback that they introduce constituent ingredients of the cosmetic formulations that are not of natural origin.
