Abstract
Skin care emulsion compositions are disclosed comprising an oil-in-water emulsion comprising phospholipid-stabilized, submicron triglyceride particles, botanical material selected from the group consisting of a vegetal material, a marine material and combinations thereof; a polycarboxylate polymer and a phosphate ester-type emulsifier. The skin care compositions can be topically applied to the skin before, and surprisingly, together with, and/or after applying a skin colorant (i.e., pigmented) cosmetic composition to moisturize the skin and achieve, augment, and/or maintain a visibly desirable cosmetic appearance.
Claims19
An aqueous topical, cosmetic skin care composition consisting essentially of the following components
- (a) an effective skin-moisturizing amount of an oil-in-water nano-emulsion comprising phospholipid-stabilized submicron triglyceride particles having a unimolecular shell of phospholipid having a phosphatidylcholine stabilizer to encapsulate an oil core comprising triglyceride and auxiliary lipophilic skin conditioning agents, water, and cosmetically acceptable water-soluble solvents selected from the group consisting of alcohol, liquid polyol and a combination thereof, the amount of oil-in-water nano-emulsion being about 0.005 to 5 parts by weight based on a total weight of the cosmetic skin care composition;
- (b) an effective skin-conditioning amount of a botanical material provided in its own individual hydroglycolic vehicle, the botanical material being selected from the group consisting of a vegetal material, a marine material, and a combination thereof, the amount of botanical material being about 0.25 to 10 parts by weight based on a total weight of the cosmetic skin care composition, the individual hydroglycolic vehicle having a pH of about pH4 to PH7;
- (c) a polycarboxylate polymer selected from the group consisting of a copolymer of two or more monomers of acrylic acid, methacrylic acid or one of their simple esters, the polycarboxylate polymer being present in the cosmetic skin care composition in an amount of 0.1 to 2 parts by weight based on a total weight of the cosmetic skin care composition;
- (d) an effective emulsifying amount of a phosphate ester-type emulsifier selected from the group consisting of a C8-C22 fatty alcohol phosphate diester, and a salt of the foregoing, the phosphate ester-type emulsifier comprising about 2 to about 20 moles of alkoxylating moieties for each fatty alcohol moiety, the amount of phosphate ester-type emulsifier being about 1 to 5 parts by weight based on a total weight of the cosmetic skin care composition;
- (e) a cosmetically acceptable auxiliary skin conditioning agent, the conditioning agent being present in the cosmetic skin care composition in an amount equal to or greater than 10 parts by weight based on a total weight of the cosmetic skin are composition;
- and
- (f) water;
- wherein the composition is an opaque emulsion in the form of a lotion or substantially semi-solid cream or paste,
- wherein the composition is a leave-on cosmetic preparation, which, on topical application to the skin, provides a lasting, water-resistant, moisturizing, conditioning film or coating thereon,
- wherein the composition has a pH of about pH 6 to pH 6.5,
- wherein the composition has a viscosity of about 50,000 to 150,000 (mPa*s) measured at temperature of about 25° C., and
- wherein the cosmetically acceptable auxiliary skin conditioning agent includes a combination of isodecyl oleate, dimethicone and cyclopentasiloxane.
