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 sun red, 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 medicine and cosmetics, in particular to the new application of medicinal plant kaempferia extract in sunscreen cosmetics and the sunscreen cosmetics containing the kaempferum extract. Background technique [0002] In recent years, due to the random discharge of Freon and other gases, the atmospheric ozone layer has become increasingly thinner, the intensity of ultraviolet rays reaching the ground has increased day by day, and ultraviolet rays have become more and more harmful to the human body. Ultraviolet light is a section of solar radiation with a wavelength of 230-400nm. According to the wavelength, it is divided into UV-A (320nm-400nm), UV-B (290nm-320nm) and UV-C (200nm-290nm), 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 organisms, and it is the main...
