Problems solved by technology

[0003] However, some difficulties are sometimes encountered when incorporating retinoids into personal care compositions, for example, after long-term storage at high temperatures, the viscosity of the composition may be affected, which may be due to the relationship between retinoids and formulations. The interaction of the components in the

Embodiment 1

[0071] This example demonstrates the preparation of a skin care composition.

[0072] Table 1

[0073]

[0074] As shown in Table 1, a series of skin care compositions were formulated.

Embodiment 2

[0076] This example demonstrates that the compositions of the invention have less viscosity change after prolonged storage.

[0077] Samples were packaged in equal quantities into identical clear jars. These packaged samples were placed in a cabinet at a preset temperature of 50°C for three months. The viscosity of the samples before and after storage was measured at 25 °C by a stress-controlled MCR 501 rheometer (Anton Paar, Physica MCR501, Austria) equipped with a blasting parallel geometry (PP25s) at a shear rate of 3.98 1 / s. The viscosity maintenance ratio was calculated by using (viscosity of sample after storage) / (viscosity of sample before storage)×100%.

[0078] Table 2

[0079] sample

[0080] Table 2 shows the viscosity retention ratios of the samples after storage at 50°C for three months. Surprisingly, it was found that by incorporating both porous silica and silicone elastomer (Sample 1) , compositions containing retinyl propionate had less viscosit...

Embodiment 3

[0082] This example demonstrates the haze performance of the personal care compositions of the present invention.

[0083] (1) The glossiness of the artificial skin was measured before and after application of the personal care composition.

Abstract

Disclosed is a personal care composition comprising retinoid, porous silica, silicone elastomer, and a cosmetically acceptable carrier.

Description

technical field [0001] The present invention relates to personal care compositions. In particular, the personal care compositions comprise retinoids which are more stable in long-term storage and have higher blurring efficacy. Background technique [0002] Retinoids, such as retinol and retinyl esters, are common ingredients used in personal care products. Retinol (vitamin A) is an endogenous compound that occurs naturally in the human body and is essential for normal epithelial cell differentiation. Natural and synthetic vitamin A derivatives have been used extensively in the treatment of various skin conditions and have been used as skin repair or renewal agents. Retinoic acid has been used to treat various skin conditions such as acne, wrinkles, psoriasis, age spots and discoloration. [0003] However, some difficulties are sometimes encountered when incorporating retinoids into personal care compositions, for example, after long-term storage at high temperatures, the ...
