Preparing method of composition with natural sun screen performance

Abstract

The invention provides a preparing method of a composition with natural sun screen performance. The preparing method comprises the steps that A-phase raw materials are sterilized, the temperature is adjusted to 75-85 DEG C, and stirring is conducted until the materials are dissolved and the mixture becomes transparent, wherein the A-phase raw materials comprise water and carbomer; B-phase raw materials are heated to 80-90 DEG C and stirred evenly, wherein the B-phase raw materials comprise one or two of glycerol monostearate and PEG-100 stearate and one or two of cetearyl olivate and sorbitanolivate; the B-phase raw materials and the A-phase raw materials are mixed evenly at 75-85 DEG C; homogeneous emulsification is conducted; C-phase raw materials are added and stirred evenly, wherein the C-phase raw materials comprise triethanolamine, a dendrobium officinale extract, a ginger extract, a magnoliae officmalis cortex extract and an angelicae sinensis radix extract. The preparing method is simple and easy to implement, and supercritical CO2 is adopted to extract natural plants, so that the extraction effect is good, and the preparing method is economical and environmentally friendly and saves energy. The prepared composition has high safety and high sun screen capacity.

Description

technical field

[0001] The invention relates to a sunscreen product, in particular to a preparation method of a composition with natural sunscreen performance. Background technique

[0002] In recent decades, the continuous destruction of the ozone layer has led to a gradual increase in the amount of ultraviolet radiation. As we all know, ultraviolet rays are divided into three categories, including short-wave ultraviolet rays (UVC) at 200-200nm, medium-wavelength ultraviolet rays (UVA) at 280-320nm, and long-wavelength ultraviolet rays (UVB) at 320-400nm. UVC can be completely absorbed by the atmosphere, while UVA and UVB through the atmosphere pose a hazard to human health, especially UVB can lead to skin pigmentation, keratin growth, photoaging, and even skin cancer and immune suppression of the body, excessive UVA ultraviolet rays Light exposure can promote the formation of wrinkles and even cause phototoxic reactions. How to reduce the occurrence of skin diseases effe...
