Composite plant extract and application thereof

Abstract

The invention discloses a composite plant extract and an application thereof. The composite plant extract comprises, by mass, 0.01-3.00 parts of Cassia alata leaf extract, 0.01-3.00 parts of Cuscuta japonica Choisy extract, 0.01-3.00 parts of Stephania cepharantha Hayata root extract, 0.01-3.00 parts of Melothria heterophylla root extract and 0.01-5.00 parts of Inula britannica extract. The synergistic compatibility of the plant extracts of the components enhances the UVA and UVB indexes of sun protection and obviously enhances the sunscreen effect of the composition, so the dosage of a sun-screening agent is reduced; and the plant extracts are fresh, cool and rapid to absorb, and can be mutually dissolved with various chemical sun-screening agents, so that the stability of the compositionsystem is enhanced, the greasy feeling of the system is reduced, the physical sun-screening agent is well dispersed, the spreadability is good, the SPF value and PA value of the composition are further improved, and the after-sun repair effects of diminishing inflammation, resisting oxidation and scavenging free radicals are achieved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, more specifically, to a compound plant extract and its application. Background technique [0002] The ultraviolet rays in the sun have been proven to be able to directly irradiate the skin and cause skin sunburn, erythema, tanning, and even cause skin photoaging and skin cancer. However, ultraviolet rays are everywhere no matter in sunny or cloudy days. The skin is being damaged by ultraviolet rays every moment. With the improvement of living standards, sunscreen products have become a must-have skin care product throughout the year in people's lives. At present, sunscreen products on the market often achieve a higher SPF by increasing the content of sunscreen agents. However, if the amount of physical sunscreen is increased, the spreading rate of the product will decrease, it will be difficult to push it away on the skin, and even the problem of rubbing mud will appear, which will greatly re...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects and deficiencies of existing sunscreen products, such as high chemical composition content, difficult absorption, and low spreading rate, and provide a composite plant extract, which can not only significantly improve the SPF and PA values ​​of sunscreen products, Spreading rate, also has the effect of anti-inflammatory, anti-oxidation and scavenging free radicals, which can significantly improve the effect of after-sun repair
