The disclosed technology relates to structurant polymers based on polyurethane/polyurea chemistry, which efficiently thicken or gel (i.e., provide structure to) oils and oil mixtures. The disclosed technology further relates to structurant polymers based on polyurethane/polyurea chemistry that are oil soluble or oil dispersible and that provide beneficial properties, such as, for example, desirable clarity and/or feel. In addition, the technology relates to cosmetically and/or household acceptable formulations containing an oil as well as a structurant polymer based on polyurethane/poly-urea chemistry.

An encapsulated perfume composition in the form of a slurry comprising one or more core-shell capsules, dispersed in an aqueous dispersing medium, wherein the core contains a perfume and the shell contains a polyurea resin, and wherein the capsules are in the form of a stable suspension having a viscosity of up to 3000 centipoise, and more particularly about 150 to 3000 centipoise when measured on a rheometer, using rotating disks at a shear rate of 21 s.sup.−1 at a temperature of 25° C.

The present disclosure is directed to a microbiostatic cleansing composition for use on skin and hard surfaces that reduces microbe resistance. The cleansing composition may be, for example, bacteriostatic or virostatic and includes a release agent that entangles the microbes without killing them allowing them to be removed from skin and hard surface in an inactive state.

A subject matter of the present invention is a composition comprising: a) at least multilayer spherical composite particles comprising i) a core comprising at least one material A having a refractive index ranging from 1.3 to 1.8; and ii) at least one layer covering said core, comprising at least one material B having a refractive index ranging from 1.9 to 3.1; and iii) optionally at least one second layer covering the material B, comprising at least one material C having a refractive index ranging from 1.3 to 1.8; said composite particles being present in an amount less than 28.0% by weight relative to the total weight of the composition; and b) at least one UV-screening agent.

This composition is for topical use and is more particularly intended for the photoprotection of the skin and/or hair against ultraviolet (UV) radiation.
