Abstract
The present invention relates to a wax-based composition comprising at least about 0.5-30% water in a water-in-oil emulsion, wherein water is encapsulated in a lamellar lipid vesicle capable of withstanding wax melting point temperatures. The composition is useful in delivering water soluble actives in an anhydrous base, and is particularly well-adapted for uses in lipsticks and lip-care products.
Claims31
A wax-based composition comprising at least about 0.5-30% water in a water-in-oil emulsion, wherein water is encapsulated in a lamellar lipid vesicle capable of withstanding wax melting point temperatures.
An anhydrous lipstick base comprising from at leastl10-40% waxes, from at least 30-80% oils, and an emulsifier, wherein at least 50% of the oil comprises one or more polar oils.
A cosmetic or pharmaceutical wax-based composition which is a water-in-oil emulsion, the emulsion comprising at least about 50% polar oils, from about 10-30% waxes, from about 0.5-5% emulsifier, and about 0.5-30% water.
A cosmetic or pharmaceutical composition for application to the lips comprising, in a water-in oil emulsion, from about 0.5-30% water, wherein water is encapsulated in a lamellar lipid vesicle which comprises at least one high-melting point polyoxyethylene fatty ether, and from 10-30% waxes, from 40-70% oils, and from 0.5-5% emulsifier, wherein at least about 50% of the composition as a whole comprises one or more polar oils selected from the group consisting of vegetable oils, triglycerides, fatty esters, or mixtures thereof.
