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, which comprises the following components: cyclopentasiloxane, polydimethylsiloxane crosslinked polymer, 1,3-propylene glycol, glycerin, retinol Palmitate, Ubiquinone, Lauryl PEG‑10 Tris(trimethylsiloxy)silylethyl Methicone, Squalane, Resveratrol, Grape Seed Oil, Peony Seed Oil. The present invention also provides a preparation method for the above vitamin A anhydrous emulsion. The vitamin A anhydrous emulsion and the preparation method thereof of the present invention adopt an alcohol-in-oil system as a solvent of cosmetics, which can reduce the inactivation of active ingredients that are easily oxidized or volatile when encountering water, and improve the utilization rate of active ingredients; Raw materials can effectively use preservatives, thereby improving the safety of the product, reducing the risk of irritation, and can also have good anti-oxidation and anti-aging effects and the effect of brightening the complexion.

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 realise. 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...
