Patent number: 12370135Abstract: An anhydrous composition for caring for and/or making up keratin materials may include: (a) 10 to 40 wt. % of at least one non-volatile non-phenyl silicone oil, relative to the total weight of the composition; (b) at least one non-volatile hydrocarbon-based oil and/or phenyl silicone oil; (c) at least one high viscosity ester; and (d) reaction product of an unsaturated-functional silicone resin, an Si—H functional organopolysiloxane crosslinker bearing pendant hydrido functionality and optionally, an unsaturated hydrocarbon having four or more carbon atoms, in a low viscosity organopolysiloxane. A process for caring for and/or making up keratin materials, such as the skin and the lips, preferably the lips, make include applying such and anhydrous composition to the keratin materials.Type: GrantFiled: December 27, 2018Date of Patent: July 29, 2025Assignee: L'OREALInventors: Tu Luan, Di Wu, Chunyan Lei, Saijuan Ni

Publication number: 20120196022Abstract: Disclosed herein is a composition (composite thickener) that generally contains about 1 wt % to about 99 wt % (e.g., 1 wt % to 99 wt %) corn fiber gum (CFG) and about 99 wt % to about 1 wt % (e.g., 99 wt % to 1 wt %) polymer thickener. The polymer thickener may be anionic polysaccharides, cationic polysaccharide, neutral polysaccharides, or mixtures thereof. When applied to aqueous solutions, CFG produced synergistic effects with one or more polymer thickener components and showed a superior thickening effect than individual CFG and other polymer thickener components.Type: ApplicationFiled: January 18, 2012Publication date: August 2, 2012Inventors: Madhav P.
