摘要： A paste-like silicone composition includes (A) crosslinked organopolysiloxane and (B) oil in a liquid state at 25° C. The component (A) includes a hydrosilylated reaction product of (A-1) organohydrogenpolysiloxane having at least two hydrogen atoms bonded to a silicon atom per molecule, and (A-2) alkenyl group-containing organopolysiloxane having at least two alkenyl groups having 2 to 10 carbon atoms and being bonded to a silicon atom per molecule. Octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane contained in the paste-like silicone composition are each less than 2,000 ppm. It is therefore possible for a stable paste-like silicone composition that has small changes over time such as plasticization return and emit less uncomfortable odor.

摘要： This disclosure describes broad-spectrum mineral sunscreen compositions (e.g., in the form of a cosmetic compact or stick), which may be untinted or tinted. Such compositions can comprise effective amounts of (a) two photoprotective metal oxides that detectably or significantly block, reflect, refract, or otherwise attenuate ultraviolet radiation, including (i) at least one zinc oxide particle, possibly an uncoated particle, and having an average particle size of greater than about 100 nanometers (ii) and at least one titanium dioxide particle, possibly a coated particle, (b) an amorphous spherical silica and (ii) material comprising light-altering frustules derived from at least one diatomaceous algal species. In some aspects, the algal material is capable of reflecting or absorbing light in a manner distinct from the zinc/titanium dioxide particles. In some aspects, the compositions are characterizable based on the composition's low water content. Such compositions can offer high SPF, water resistance, and non-skin-whitening properties.

摘要： Described herein is a crosslinked organosilicone resin that has a crosslinked structure formed by reacting a silicone or hydrocarbon having an alkenyl group at both ends thereof with a hydrosilyl group-containing organosilicone resin, is soluble with a liquid oil at room temperature, and forms a film by volatilization of the oil. Also described herein is a method for preparing a crosslinked organosilicone resin and cosmetics containing a crosslinked organosilicone resin.
