Abstract

The invention discloses a new application of kaempferol extractive and a sunscreen cosmetic containing kaempferol extractive, belonging to the technical field of Chinese traditional medicine and cosmetic, wherein kaempferol extractive has strong ultraviolet absorption in UV-B range, has strong absorption strength, can effectively absorb ultraviolet of sunlight so as to prevent human skin from sunred, sunburn and tanning, can heal photosensitive dermatitis, and can be used as sun screening component of sunscreen cosmetic to be combined with variable sun screening agents to prepare sunscreen skin-care cosmetic. The produced cosmetic has high sunscreen index and is safer than chemical sun screening agent, and has small possibility of allergy effectively. Kaempferol is special medicinal and edible plant at south area, having wide source and plantation in Guangdong, Guangxi and Yunnan.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicines and cosmetics, in particular to a new application of medicinal plant kaempferia extract in sunscreen cosmetics and sunscreen cosmetics containing the kaempferia extract. Background technique [0002] In recent years, due to the random emission of Freon and other gases, the atmospheric ozone layer has become increasingly thin, the intensity of ultraviolet rays reaching the ground has increased, and the damage of ultraviolet rays to the human body has become more and more serious. Ultraviolet rays are a segment of solar radiation, with wavelengths ranging from 230-400nm, and are divided into UV-A (320nm-400nm), UV-B (290nm-320nm) and UV-C (200nm-290nm) according to wavelength, which can reach the earth. There are only very low doses of UV-A and very small doses of UV-B, while UV-C cannot reach the surface of the earth. Among them, UV-B is the most harmful to living beings and is the main...
