Problems solved by technology

[0005] However, after applying the cosmetic composition, the skin may be subjected to washing and abrasion by hands, and thus the film formed on the skin by the film-forming polymer may be easily removed Washes away and / or erases, thus losing firming benefits
At the same time, benefit agents can be easily washed off and / or rubbed off, thus not providing long-lasting benefits

Embodiment 1

[0111] This example demonstrates that the inclusion of cholesterol in compositions comprising different silicone resins improves the wash-off resistance, abrasion resistance and thus deposition of benefit agents of the films.

[0112] A series of cosmetic compositions were formulated as shown in Table 1 below. The formulations were prepared by the following method. The optical particles are thoroughly dispersed in the oil phase along with the other ingredients and the silicone resin and / or cholesterol (when present) and mixed thoroughly. The resulting oil-based mixture was gradually added to the water phase. The resulting mixture was emulsified at 65° C. for 10 minutes under a shear stress of 9,000 rpm, and gradually stirred and cooled to room temperature.

[0113] The deposition rate of the samples was measured by the following wash-off / abrasion resistance performance test.

Embodiment 2

[0124] This example demonstrates that compositions containing varying amounts of silicone resin and cholesterol improve film wash-off resistance, abrasion resistance and thus deposition of benefit agents.

[0125] The formulations in Table 3 were prepared and tested for deposition rate by following a procedure similar to that described in Example 1.

[0126]

[0127]Table 4 shows the deposition rates of compositions comprising silicone resin and cholesterol having different concentrations and weight ratios. Compositions of the invention (samples 4, 5, 6, 7 and 8) had improved deposition by the addition of cholesterol, which means that compositions comprising silicone resin and cholesterol in different ratios and / or concentrations can improve resistance. Wash-off, rub resistance and deposition of optical particles. A composition comprising silicone resin and cholesterol in a silicone resin to cholesterol weight ratio of 1:2 (sample F) did not show improved deposition.

Abstract

Disclosed is a cosmetic composition comprising a film-forming polymer having a contact angle of at least 85 degrees, a steroid, and cosmetically acceptable carrier, wherein the weight ratio of the film-forming polymer to the steroid is at least 5:9, wherein the film-forming polymer is selected from silicone resin, non-silicone resin film-forming polymer or a mixture thereof. The composition is capable of forming a film on skin to improve the benefits of skin firming, wash-off resistance, abrasion resistance, and / or long-lasting deposition of beneficial agent.

Description

Area of invention [0001] The invention involves a cosmetic composition.Specifically, the present invention involves a cosmetic composition, which contains a film polymer with at least 85 ° contact angle, the puppet compound and cosmetics acceptable carrier.The weight ratio of compounds is at least 5: 9, wherein the membrane polymer is selected from silicone resin, non -silicone resin film polymer or mixture.The composition can be used to apply local application to the skin, especially to form a membrane that has improved skin firming, washing resistance, abrasion resistance, and accumulation of beneficial reagents, and the long -lasting sedimentation of beneficial reagents. Invention background [0002] Under normal circumstances, consumers have some skin problems including dryness, wrinkles and fine lines, relaxation / drooping skin and old spots.For consumers, cosmetic compositions containing film polymer may be a solution for these problems.After local application, the film pol...
