The present invention relates to a composition, notably an aqueous cosmetic composition, comprising at least one screening agent chosen from water-soluble or water-dispersible screening agents that are capable of absorbing UV rays from 320 to 400 nm (UVA), water-soluble or water-dispersible screening agents that are capable of absorbing UV rays from 280 to 320 nm (UVB), and mixtures thereof; at least one hydrophilic thickener; and at least one surfactant with an HLB of greater than or equal to 7.
The present invention also relates to a non-therapeutic cosmetic process for treating keratin materials, preferably the skin, comprising the application, to said keratin materials, of a composition according to the invention.
Inorganic sunscreen agents with higher UV radiation protection
Ultraviolet radiation sun protective compositions are reported which feature micronized metal oxide inorganic particles selected from zinc oxide, titanium oxide and mixtures thereof, the inorganic particles being coated with poly[C.sub.8-C.sub.20 hydroxycarboxylic acid], the coated particles measured at a 10% loading in dodecane and 1 minute elapsed time having a Zeta Potential ranging from 2 to 10 mv, amounts of the poly[C.sub.8-C.sub.20 hydroxycarboxylic acid] to the inorganic particles being in a relative weight ratio of 1:100 to 1:10.
Personal Care Compositions
Described herein are personal care compositions that may include from about 0.1 to about 5 wt. % of a polysaccharide; from about 0.01 to about 12 wt. % of a fatty alcohol; and from about 0.5 to about 7 wt. % of a post-biotic blend, wherein all weight percentages are based on the total weight of the personal care composition. Methods of making and using these personal care compositions are also described herein.
RAW MATERIAL FOR COSMETIC AND OIL-IN-WATER EMULSION COSMETIC COMPRISING CORE-CORONA POLYMER PARTICLE
Provided are: a core-corona polymer particle excellent in emulsion stability and feeling of use, and a raw material for a cosmetic and an oil-in-water emulsion cosmetic comprising the particle. The present invention provides a core-corona polymer particle obtained by radical-polymerizing a polyethylene oxide macromonomer represented by the formula (1) and one or two or more of hydrophobic monomers represented by the formulas (2) and (3) under the following conditions (A) to (D).
Encapsulated fragrance compounds based on natural amino acids
The present invention relates to a process for the production of multilayer microcapsules, in particular multilayer odiferous substance capsules or fragrance compound capsules, which have improved stability and odiferous substance release or fragrance compound release compared to prior art capsules. In addition, the present invention relates to multilayer microcapsules comprising at least one hydrophobic odiferous substance or fragrance compound obtainable by the process of the invention. In another aspect, the invention described herein relates to multilayer microcapsules comprising a core comprising at least one hydrophobic odiferous substance or fragrance compound, and a capsule shell.
