摘要:
The disclosure relates to sunscreen compositions having a synergistic combination of titanium dioxide filtering agents that provide a high sun protection factor (SPF). Compositions according to the disclosure have high SPF values without requiring high overall amounts of titanium dioxide filtering agents. Also, the sunscreen compositions are less opaque and white than traditional sunscreens making them aesthetically appealing to consumers. Finally, the disclosure relates to methods of using the described compositions for protecting keratinous substances such as skin and hair from UV radiation.

The application describes a process for producing microcapsules which contain a shell made of polyurea and which surround in their interior a fragrance oil core, where the shell is obtained by the reaction of two structurally different diisocyanates in emulsion form.
摘要:
Disclosed are oral care compositions, for example dentifrice compositions, comprising an orally acceptable vehicle, metal oxide particles having an average particle size of no greater than a dentin tubule and a polymeric adherent material for adhering the metal oxide particles in the dentin tubule. The metal oxide particles have a median particle size of 5 microns or less, and may comprise zinc oxide.
摘要:
The present invention provides a sunscreen cosmetic comprising: (1) an UVA absorbent selected from one, two or more from hexyl diethylaminohydroxybenzoylbenzoate, 2,4-bis{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine, 4-tert-butyl-4-methoxydibenzoylmethane, and 2-hydroxy-4-methoxybenzophenone, and (2) resin spherical powder containing inside 35% or more of hydrophobicized ultra fine particles of titanium oxide.The object of the present invention is to provide a sunscreen cosmetic containing an UVA absorbent and ultrafine particles of titanium oxide wherein staining of clothing due to secondary adhesion is prevented.
摘要:
A composition comprising a pigment particle that is coated with Polyquaternium-67. The pigment particle can be included in a cleansing composition for deposition on a surface, such as skin.
摘要:
Cosmetic agent for temporarily deforming keratin fibers, comprising a polysilicic acid in a cosmetically acceptable carrier, wherein the polysilicic acid is coated with at least one copolymer A formed from at least one monomer A1 according to Formula (A1) wherein R1 is H or CH3, R2 and R3 each independently of each other mean H, OH, C1-10-Alkyl or C1-10-Alkoxy, under the provision that at least one of the radicals R2 or R3 is OH, and n is a whole number from 0 to 20, and at least one monomer A2 according to Formula (A2) wherein R4 is H or CH3, Z is O or NH, and R5 is C1-30-alkyl or C1-30-alkylene-C1-30-alkylether group, use of the agent for temporarily deforming keratin fibers, and method of deforming hair using such agent.
摘要:
Silicone-free compositions including hydrocarbons of widely different structures and origins combined with coated particles are provided which have both aesthetic and volatility properties similar to cyclopentasiloxane dispersions. The compositions are useful as full or partial replacement products for dispersions of cyclopentasiloxane, or “volatile silicones.” The compositions are useful in UV-attenuating formulations including skin care products, color cosmetics, pharmaceutical products and especially sun care products such as sunblocks, sunscreens, tanning lotions, and the like.
摘要:
An object of the present invention is to provide a core-shell-type cerium oxide microparticle, a dispersion solution comprising the microparticle, and a process for production of the microparticle or dispersion solution, and to achieve the object, the present invention provides a core-shell-type cerium oxide microparticle which has an average particle diameter of 30 to 200 nm and a coefficient of variation therein no greater than 0.25, and in which the secondary particle forming the core portion is spherical in shape and a polymer is attached to its surface, a dispersion solution of this cerium oxide microparticle and a dry powder from the cerium oxide microparticle dispersion solution, and a process of producing a core-shell-type cerium oxide microparticle or a dispersion solution thereof, which comprises the steps of: mixing a cerium salt and a polymer in an organic solvent to obtain a mixture; and heating this mixture under reflux at a prescribed temperature to precipitate core-shell-type cerium oxide microparticles, wherein the cerium salt is cerium nitrate and the particle diameter of the microparticles is adjusted using the molecular weight of the polymer.
