Abstract
The present invention relates to a process for increasing the persistence of at least one cosmetic and/or care effect of a cosmetic composition comprising an oily phase. This process comprises the incorporation into this oily phase of at least one linear or cyclic polyorganosiloxane which comprises at least two organosiloxy units and at least two side and/or end groups which are each capable of forming at least one hydrogen bond with one or more partner groups. The process may be applied, for example, to lipsticks, mascaras or eyeliners to increase the persistence of their coloring effect and/or gloss, to foundations, powders, blushers and eyeshadow to increase the persistence of the matt effect, and to care products such as moisturizing products, deodorants or antiperspirants to increase the persistence of their active care agents. The invention also relates to a cosmetic composition, the persistence of at least one cosmetic and/or care effect of which is increased, and which is intended to be used on the skin, the lips and superficial body growths.
