    摘要: The present invention provides an anhydrous sunscreen composition comprising: (a) at least about 15% by weight based on the total weight of the sunscreen composition of a combination of titanium dioxide and zinc oxide, wherein the weight ratio of zinc oxide to titanium dioxide in the composition is about 0.5 to about 1.5; (b) at least about 50% by weight based on the total weight of the sunscreen composition of a carrier oil, wherein the carrier oil comprises at least 50% by weight Helianthus Annuus (Sunflower) Seed Oil; (c) about 10% to about 20% by weight based on the total weight of the sunscreen composition a combination of Isododecane and Diisopropyl Adipate; and (d) about 2% to about 6% by weight based on the total weight of the sunscreen composition of a film former comprising triacontanyl PVP.

    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: The inventive cosmetic includes; (A) organosiloxane represented by the following formula (1), and having a boiling point in a range of 205 to 255° C. and a kinematic viscosity at 25° C. of less than 5 mm2/s; and (B) volatile oil having a kinematic viscosity at 25° C. of 2 mm2/s or less, excluding the component (A).




    wherein, R each independently may be identical to or different from one another and represents a group selected from the group consisting of a hydrogen group, a hydroxy group, and a monovalent hydrocarbon group having 1 to 3 carbon atoms. “a” is an integer from 1 to 5. It is provided that at least one of R is a monovalent hydrocarbon group having 2 or 3 carbon atoms. This cosmetic can provide a light feeling, good spreadability and a uniform cosmetic film, and exhibit excellent stability over time and excellent cosmetic durability.
