POUDRE COMPOSITE FONCTIONNELLE BLOQUANT LES UV ÉLABORÉE PAR LE DOUBLE ENROBAGE D'UNE POUDRE INORGANIQUE AVEC UN AGENT BLOQUANT LES UV INORGANIQUE ET UN ABSORBEUR UV ORGANIQUE, ET COMPOSITION COSMÉTIQUE BLOQUANT LES UV ASSOCIÉE
The present invention relates to a UV blocking functional composite powder prepared by doubly coating an inorganic powder with an inorganic UV blocking agent and an organic UV absorbent, and a UV blocking cosmetic composition using the same. More specifically, a UV blocking organic-inorganic composite powder is completed by primarily coating an inorganic powder such as talc and sericite, as a coating base material, with titanium oxide and zinc oxide which are inorganic UV blocking agents, secondarily coating the inorganic powder by liposomizing ethylhexyl methoxycinnamate or butyl methoxydibenzoylmethane which are organic UV absorbents, and then tertiarily coating the inorganic powder with triethoxycaprylylsilane. The UV blocking organic-inorganic composite powder effectively blocks ultraviolet rays in UV-A and UV-B ranges and simultaneously prevents the organic UV absorbent from being directly applied and absorbed into the skin by encapsulating the organic UV absorbent, which may cause skin irritation, through a liposomation process, and also prevents an outflow of the coated organic absorbent, thereby maximizing a UV blocking capability without being harmful to the human body.
