Abstract
Stable photoprotective cosmetic emulsions, notably water-in-oil emulsions well suited for the UV-photoprotection of the skin, lips, mucous membranes and/or hair, contain at least one aqueous phase, at least one oily phase, an effective UV-photoprotecting amount of at least one coated or uncoated metal oxide UV-blocking agent and an effective stabilizing amount of at least one amphiphilic oligomer or polymer derived from a polyolefin which also comprises at least one polar moiety, formulated into a physiologically acceptable medium therefor.
Claims27
A photoprotective cosmetic emulsion comprising at least one aqueous phase, at least one oily phase, an effective UV-photoprotecting amount of at least one metal oxide UV-blocking agent and an effective stabilizing amount of at least one amphiphilic oligomer or polymer derived from a polyolefin which also comprises at least one polar moiety, formulated into a physiologically acceptable medium therefor.
A regime or regimen for the UV-photoprotection of the skin, lips, mucous membranes and/or hair, comprising topically applying thereon a photoprotective cosmetic emulsion which comprises at least one aqueous phase, at least one oily phase, an effective UV-photoprotecting amount of at least one metal oxide UV-blocking agent and an effective stabilizing amount of at least one amphiphilic oligomer or polymer derived from a polyolefin which also comprises at least one polar moiety, formulated into a physiologically acceptable medium therefor.
A method for stabilizing a photoprotective emulsion comprising at least one UV-blocking metal oxide, which comprises formulating therein an effective stabilizing amount of at least one amphiphilic oligomer or polymer derived from a polyolefin and which also comprises at least one polar moiety.
