[0074] The second aspect of the present invention provides a method for preparing the retinol-based coating according to the first aspect, including the step of mixing the components of the retinol-based coating.

[0075] Further, the preparation method of the retinol-based coating includes the step of mixing the components of the retinol-based coating at room temperature.

[0076] In some specific embodiments, the preparation method of the retinol-based coating comprises the following steps:

[0077] mixing the retinol-based oil blend with the first thickener;

[0078] mixing the retinol-based mixed oil with the mixture of the first thickener, the second thickener and the third thickener to obtain a blend;

[0079] The blend was dispersed in dimethicone to obtain a retinol-based coating.

[0080] For mixing the retinol-based mixed oil with the first thickener, it means mixing the retinol-based mixed oil with the first thickener of the powder, and stirring until the first th...

Embodiment 1-3

[0136] The three groups of retinol-based wraps in Examples 1-3 were prepared according to the component contents provided in Table 1, and the preparation method of each group of retinol-based wraps specifically included the following steps:

[0137] (1) Mix retinol or retinyl palmitate with polydimethylsiloxane with a viscosity of 6η at a ratio of 1:1 at room temperature to obtain a retinol-based mixed oil.

[0138] Among them, retinyl palmitate is added in Example 1, retinol is added in Example 2, and a mixture of retinol and retinyl palmitate is added in Example 3, wherein retinol and retinol palmitate The mass ratio of esters is 1:1.

[0139] (2) Mix the retinol mixed oil obtained in step (1) with vinyl polydimethylsiloxane / polymethicone silsesquioxane crosslinked polymer into powder to absorb the oil body Dry.

[0140] (3) Mix the mixture obtained in step (3) with polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer, hydroxyethyl acrylate / sodium acryloyldi...

Abstract

The invention relates to a retinol inclusion as well as a preparation method and application thereof, and belongs to the field of cosmetics. The invention provides a retinol inclusion. The retinol inclusion comprises the following components of retinol mixed oil, a thickening agent, and a polydimethylsiloxane; the thickening agent comprises a first thickening agent, a second thickening agent and athird thickening agent; the mass ratio of the retinol mixed oil to the first thickening agent is (2-4): 1; and the first thickening agent, the second thickening agent, and the third thickening agentmay be the same or different. The retinol inclusion disclosed by the invention can form stable inclusion for retinol compound, so that slow release of the retinol compound is realized, and damage to the retinol compound cannot be caused; and furthermore, the retinol inclusion disclosed by the invention is applied to a skin care product, so that the utilization rate of the retinol compound in the skin care product can be increased, and the skin care product achieves the effects of effectively removing wrinkles and resisting aging.

Description

technical field [0001] The invention relates to a retinol-based wrap and its preparation method and application, in particular to a retinol-based wrap and its preparation method and application, and belongs to the field of cosmetics. Background technique [0002] Retinoic acid (also known as vitamin A acid, retinoic acid) is an intermediate product of vitamin A metabolism in the body, and plays an important regulatory role in the process of human growth, development and cell differentiation. Retinoic acid can not only promote the synthesis of collagen, but also promote the formation of elastin fibers, which has a good anti-wrinkle effect. However, retinoic acid is irritating to the skin, and symptoms such as redness and itching may appear after application. Compared with vitamin A acid, vitamin A alcohol (also known as: retinol) and vitamin A alcohol ester (also known as: retinol ester) are less irritating, and are usually used in cosmetics instead of vitamin A acid.
