Embodiment 1

[0181] Example 1: Glycerin as a Hydrophilic Benefit Agent

[0182] Add 1 mL of 0.01 N HO to the container containing the tape strips 2 SO 4 aqueous solution and 9 mL of methanol, vortexed for 1 min, sonicated for 10 min, allowed to stand for 30 min, and filtered using a 0.45 μm pore size syringe filter. The total volume of the filtrate was concentrated to 1 mL using a gentle nitrogen stream. Using a high-performance liquid chromatograph (HPLC, model 2595, Waters Corp., Milford, MA) equipped with a differential refractometer detector (model 2414, Waters Corp.), the following conditions were used: 1OA-1000 chromatographic column (300mm ×7.8mm, Alltech Associates, Inc., Deerfield, IL), 0.01N H at 65°C 2 SO 4 The isostatic flow rate of the aqueous solution is 0.6ml min -1 , and the injection volume was 10 μL.

Embodiment 2

[0183] Example 2: Using dihydroxyacetone as a hydrophilic benefit agent

[0184] Add 1 mL of 0.005 N H to the container containing the tape strips 2 SO 4 aqueous solution and 9 mL of methanol, vortexed for 1 min, sonicated for 10 min, allowed to stand for 30 min, and filtered using a 0.45 μm pore size syringe filter. The total volume of the filtrate was concentrated to 1 mL using a gentle nitrogen stream. Using HPLC (model 2595, Waters Corp.) equipped with differential refractometer detector (model 2414, Waters Corp.), apply the following conditions: 10A-1000 chromatographic column (300mm * 7.8mm, Alltech Associates, Inc.), 0.005N H at 65°C 2 SO 4 The isostatic flow rate of the aqueous solution is 0.6ml min -1 , and the injection volume was 40 μL.

Embodiment 16 to 18

[0204] The above compositions can be prepared by conventional formulation and mixing techniques. Additional aqueous phase compositions were prepared by forming the following premixes: citric acid was added to water at a 1:1 ratio to form a citric acid premix, and polyox WSR-301 was added to glycerin at a 1:3 ratio to form polyox-glycerin premix, and cosmetic pigments were added to glycerin at a ratio of 1:20 to form a pigment-glycerin premix and mixed well using a high shear mixer. Then, add the following ingredients to the main mixing vessel in the following order: water, N-Hance 3196, polyox premix, citric acid premix, edetate disodium, and Miracare SLB-365. Stir for 30 minutes, then begin heating the batch to about 49°C. Add CMEA and stir until homogeneous. The batch was then cooled to ambient temperature and the following ingredients were added: sodium chloride, 1,3-dimethylol-5,5-dimethylhydantoin, cosmetic pigment premix, and fragrance. The batch was stirred fo...

Abstract

A personal care composition that comprises a sunless tanning active, a surface active, a lipid, and an aqueous phase; wherein the lipid, the sunless tanning active, and the surface active form a lipid phase; wherein the sunless tanning active and the surface active are on the surface of the lipid, within the domain of the lipid, or both on the surface and within the domain of the lipid in the lipid phase. These compositions deposit sunless tanning actives on keratinous surfaces as well as provide improved skin moisturization, appearance, aesthetics and skin feel during and/or after application. The present invention is further directed to a method of using the personal care composition.

Description

field of invention [0001] The present invention relates to the field of personal care compositions for delivering sunless tanning actives to keratinous surfaces and improving keratinous surface moisturization as well as appearance and feel. More specifically, the present invention relates to rinse-off personal care compositions that deposit hydrophilic benefit agents containing sunless tanning actives on keratinous surfaces and provide superior skin moisturizing, conditioning, Adds color and shimmer. Background of the invention [0002] Personal care compositions are well known and widely used. These compositions have long been used to clean and moisturize the skin, deliver actives, conceal blemishes and reduce oiliness and shine associated with sebum. While the compositions and disclosures of the prior art provide useful developments in the field of personal care compositions, there remains a need for improved personal care compositions that provide improved skin moisturi...
