Problems solved by technology

Generally, moist heat sterilization requires a temperature higher than 115 °C and lasts for a long time, which cannot be satisfied by general cosmetic production equipment; while for irradiation sterilization, many ingredients in skin care products are prone to discoloration, odor irritation, extreme pH and raw materials after irradiation. changes in body properties
[0005] Patent CN201810708974.3 discloses a neutral preservative-free exfoliating composition, including a film-forming copolymer, a pH regulator, and carbomer. No preservatives are added, but a relatively high content of pentylene glycol and ethanol is added. The two ingredients are highly irritating to sensitive skin; in addition, there is no effective sterilization method in the product preparation process, and reliable sterilization cannot be achieved only by heating the material to 80-85°C and keeping it warm for 10 minutes

Abstract

The invention belongs to the technical field of skincare products and particularly relates to a skincare composition and a preparation method thereof. The skincare composition comprises, by weight, 2-20 parts of polyol moisturizing agent, 0.05-0.4 part of sodium hyaluronate, 0-0.2 part of xanthan gum, 0.5-2.5 parts of trehalose and 0-0.6 part of antioxidant. The skincare composition is sterile, free of preservatives, high in moisturizing and anti-oxidation effect, simple in preparation method and applicable to skincare products such as moisturizing spray, toner, essence and lotion.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and in particular relates to a skin care composition and a preparation method thereof. Background technique [0002] Dry skin is one of the very common skin problems in daily life, which can be relieved by moisturizing and hydrating. Existing moisturizing products on the market include moisturizing water, moisturizing spray, moisturizing cream, moisturizing milk and so on. [0003] Moisturizing products often achieve the effect of sterilization and prolonging the shelf life by adding preservatives. Patent CN201610816339.8 provides a skin care spray that can adjust the water-oil balance of the skin, adding preservatives such as methylparaben and phenoxyethanol. However, while preservatives kill microorganisms, they can cause different degrees of irritation and damage to human skin, which brings risks to skin safety. [0004] In addition to adding preservatives to inhibit the growth o...
