Abstract:
PURPOSE: Polymer capsules containing an ultraviolet absorber and a preparation method thereof, and cosmetics containing the same polymer capsules are provided, which polymer capsule has improved stability in cosmetic formulations without loss of ultraviolet blocking effect, so that it can be useful for production of ultraviolet blocking cosmetics. CONSTITUTION: The polymer capsules contains 0.01 to 90 wt.% of the ultraviolet absorber in hydrophobic polymer, wherein the polymer capsule has the size of 0.01 to 1,000 micrometer. The method for preparing the polymer capsules containing ultraviolet absorber comprises the steps of: (1) dissolving polymer in solvent; (2) dispersing the ultraviolet absorber in the polymer solution; (3) emulsifying the ultraviolet absorber containing polymer solution in the presence of a dispersion stabilizing agent to prepare emulsion; and (4) removing solvent from the emulsion and recovering the soft polymer capsules, wherein the dispersion stabilizing agent is one or more selected from gellatin, starch, hydroxyethylcellulose, carboxymethylcellulose, polyvinylpyrrolidone, polyvinyl alkyl ether, polyvinyl alcohol and polydimethylsiloxane/polystyrene block copolymer.
Abstract:
PURPOSE: Provided are novel retinoid derivatives and methods for preparation thereof, thereby increasing stability of the retinoid derivatives, allowing them to be easily dispersed, controlling their absorption into the skin and decreasing the skin irritation. CONSTITUTION: Novel retinoid derivatives are characteristically manufactured by covalent bond of retinoid with an aromatic polyester based polymer. The retinoid-polyester copolymer inhibits the inactivation and crystallization of retinoid, therefore, it increases stability of the retinoid derivatives, allows them to be easily dispersed, controls their absorption into the skin and decreases the skin irritation.
