Abstract
The present invention relates to compositions delivering enhanced visual benefits to the skin with specific optical attributes. These are delivered using specific deposition systems (where oil/emollient comprises part of deposition system) and/or by ensuring dispersion of particles.
Claims12
A rinse-off bar or liquid composition for delivery of enhanced visual benefits to the skin with specific optical attributes consisting of:
- a) from about 0.5% to about 90% by wt. surfactant system comprising C10-C24 fatty acids, alkyl taurates, and oxyalkylene ethers;
- b) from 0.1 to 35% by wt. of solid particulate optical modifier which exhibits a specific set of optical properties, defined by ΔL, Δa*, Δb*, change in reflectivity and/or change in opacity, and which, in combination with a deposition enhancement system, provides at least 5% change in at least one of said optical properties being targeted when said composition is applied to the skin;
- c) from 0.1 to 25% by wt. of a deposition enhancement system comprising (i) 0.1 to 10% by wt. of a cationic polyquaternium 6 polymer or polymers having an average charge density of about 6.2 meq/g;
- and (ii) anionic surfactant and optionally (iii) about 0.1 to 30% by wt. of a granular anionic polymer which is a natural alkaloid polymer which forms precipitate with said cationic polymer or polymers upon dilution and selected from the group consisting of C10 to C24 fatty acid soap, alkyl taurates, and mixtures thereof;
- and
- d) from about 0.1 % to 90% of a hydrophilic structural dispersant comprising alkylene glycol, maltitol and glycerin;
- wherein the deposition enhancement system further comprises oil/emollient enveloping/surrounding said optical modifier;
- and/or comprises oil/emollient which forms an emulsion system in which optical modifier particles are emulsified in the oil/emollient or are enveloped by the oil/emollient during dilution with water.
