Abstract

The invention relates to a skin protectant and a preparation method thereof and solves the technical problems of irritation, low volatility, slow film formation speed and insufficient adhesion force of the existing reagent. The skin protectant is specifically prepared from the following components in percentage by weight: 80-95% of siloxane, 2-15% of siloxy silicate, 0.2-3% of polysiloxane, 0.2-3%of an ultraviolet light absorber and the balance of auxiliary components. The invention provides the preparation method of the skin protectant. The skin protectant can be widely used in the field ofthe skin protectants.

Description

technical field [0001] The invention relates to the field of biochemical industry, in particular to a skin protectant and a preparation method thereof. Background technique [0002] Skin protectants are usually used for the protection needs of the more sensitive skin of the human body. They are usually used to solve the damage to the skin when the medical tape is peeled off, and to prevent the feces and urine from the stoma site from polluting and corroding the intact skin. It can also be added by adding other Active ingredients provide additional functions. [0003] The skin protection function is mainly achieved by attaching a layer of barrier ingredients to the skin. In order to achieve a uniform protection function, the main forms of the product include spray spray, wet sheet wipe, and cream application. Common product compositions include water / ethanol solution system, organic solvent system, carbomer gel system and multi-composition cream cosmetics. [0004] The dama...
