Description

The present invention relates to compositions in the form of reclaimed water (W / O) emulsions, more particularly cosmetic compositions for making up and / or caring for the skin.

The use of W / O emulsions is a known practice in the field of cosmetics or dermatology. These emulsions, which consist of an aqueous phase dispersed in the fat phase, have an outer fat phase, so cosmetic / dermatological products based on W / O emulsions can provide a comfortable sensation. can.

On the other hand, there are cosmetics (eg WO2013 / 105804 and WO2013 / 002523) in which liquid cosmetics are impregnated in a carrier such as a sponge in a container. The user of the cosmetic can use the puff, for example, to suck the liquid cosmetic from the carrier. The use of carriers can make the use of liquid cosmetics easier.

Walter Noll, Chemistry and Technology of Silicones (1968), Academic Press Cosmetics and Toiletries, Vol. 91, January 1976, pp. 27-32, Todd & Byers "Volatile Silicone Fluids for Cosmetics" ASTM Standard 445 Appendix C CTFA (6th edition, 1995)

However, it is often difficult to retain liquid cosmetics in the carrier. In particular, W / O emulsions can be difficult to retain in carriers because their outer phase is substantially made up of fluid-prone oils. If a liquid cosmetic such as a W / O emulsion cannot be retained in the carrier, the liquid cosmetic may leak from the carrier, or even from the container.

Leakage may be reduced by thickening the oil in the W / O emulsion. However, thickening the oil will substantially reduce the fresh sensation.

An object of the present invention is from a carrier or from a container containing a carrier while retaining good cosmetic properties such as a comfortable feel, smooth ductility and a natural finish with a good coverage of defects on the skin.
