Claims19
A cosmetic composition comprising a water phase having solubilized 4-hydroxyacetophenone with niacinamide and an oil phase, the cosmetic composition being formed by the steps consisting essentially of providing an oil composition comprising at least one branched or linear, liquid alkane with carbon chain length of C11 to C20 comprising isohexadecane, at least one polar emollient with molecular weight of 400 g/mol or less, and at least one alkylated glycerol ester surfactant comprising PEG-7 glyceryl cocoate and combining the oil composition with an aqueous composition having each of 4-hydroxyacetophenone and niacinamide to form the cosmetic composition,
- wherein:
- the cosmetic composition is free of essential oils other than fruit extracts, aloe vera extract, and seaweed extract;
- one or more humectants may be present in the cosmetic composition;
- the at least one polar emollient with molecular weight of 400 g/mol or less comprises isopropyl myristate present in an amount from about 4% to about 12% by weight, based on the total weight of the cosmetic composition;
- the total amount of the one or more humectants is 5.5% by weight or less, based on the total weight of the cosmetic composition;
- the niacinamide is present in an amount of 1% to 3.5%, based on the total weight of the cosmetic composition;
- and
- the isohexadecane is present in an amount from about 4% to about 12% by weight, based on the total weight of the cosmetic composition.
A cosmetic composition including a water phase and an oil phase, the oil phase comprising at least one branched or linear, liquid alkane with carbon chain length of C11 to C20 comprising isohexadecane, and at least one alkylated glycerol ester surfactant comprising PEG-7 glyceryl cocoate, and the water phase comprising solubilized 4-hydroxyacetophenone with niacinamide, wherein the weight ratio of niacinamide to 4-hydroxyacetophenone in the water phase is at least 3.0, and wherein one or more humectants may be present in the cosmetic composition, and:
- the 4-hydroxyacetophenone is present in an amount from about 0.15% to 0.6%, by weight, based on the total weight of the cosmetic composition;
- the total amount of the one or more humectants is 5.5% by weight or less, based on the total weight of the cosmetic composition;
- the niacinamide is present in an amount from about 1% to about 2.2%, by weight, based on the total weight of the cosmetic composition and
- the isohexadecane is present in an amount from about 4% to about 12% by weight, based on the total weight of the cosmetic composition,
- wherein the cosmetic composition is free of essential oils other than fruit extracts, aloe vera extract, and seaweed extract.
A makeup removal and cleansing article, comprising:
- a. a water-insoluble substrate;
- and
- b. impregnated in the water-insoluble substrate a cosmetic composition including a water phase, the water phase comprising solubilized 4-hydroxyacetophenone with niacinamide, wherein the weight ratio of niacinamide to 4-hydroxyacetophenone in the water phase is at least 3.0,
- wherein:
- the cosmetic composition is free of essential oils other than fruit extracts, aloe vera extract, and seaweed extract;
- one or more humectants may be present in the cosmetic composition;
- the total amount of the one or more humectants is 5.5% by weight or less, based on the total weight of the cosmetic composition;
- and
- the niacinamide is present in an amount of about 1% to about 2.2%, based on the total weight of the cosmetic composition.
