Problems solved by technology

[0005] At present, there are two difficulties in the anhydrous system: 1. Replacing the best solvent "water" in nature with "polyol" puts forward higher technological requirements for the solubility of active substances; 2. Different from traditional water agents Or cream products, using "polyol" to replace "water", the best solvent in nature, also poses a higher challenge to product stability

Abstract

The invention provides an anhydrous vitamin A emulsion. The anhydrous vitamin A emulsion comprises decamethylcyclopentasiloxane, a polydimethylsiloxane cross-linked polymer, propan-1,3-diol, glycerinum, retinyl palmitate, ubiquinone, lauryl PEG-10 tris(trimethylsiloxy) silylethyl dimethicone, squalane, resveratrol, grape seed oil and peony seed oil. The invention further provides a preparation method of the anhydrous vitamin A emulsion. According to the anhydrous vitamin A emulsion and the preparation method thereof, an alcohol-in-oil system serves as a solvent of cosmetics, inactivation of active ingredients which are easily oxidated or denatured in water can be reduced, and the utilization rate of the active ingredients is increased. By using the natural and safe raw materials, a preservative can be effectively prevented from being used, the safety of the product is improved, and the risk of irritation is reduced; the anhydrous vitamin A emulsion can have good anti-oxidant and anti-aging effects and further can have an effect of brightening the skin color.

Description

technical field [0001] The invention relates to an emulsion and a preparation method thereof, in particular to an anhydrous vitamin A emulsion and a preparation method thereof. Background technique [0002] Water is an indispensable basic raw material in cosmetics; at the same time, it is also the best solvent in nature. Water, as the most important raw material in cosmetics, usually accounts for 60%-80%, or even higher. [0003] However, when water is used as a solvent for cosmetics, chemical modification, microencapsulation or process improvement are usually required for active ingredients that are easily oxidized and attenuated when exposed to water, or polypeptide ingredients that need to be effective within a specific pH range to fulfill. Among them, the safety risk caused by the residual by-products of chemical modification cannot be underestimated; microcapsule encapsulation and process improvement have correspondingly increased the timeliness of product development...
