Document Type and Number:
WIPO Patent Application WO/2024/066643
Kind Code:
A1
Abstract:
Provided is a sun-screening composition, which comprises the following components in parts by weight: 0.1-5 parts of polyglutamic acid, 2-5.5 parts of a sophora flower extract, 20-40 parts of a physical sun-screening agent, 0.5-5 parts of ascorbic acid and/or an ascorbic acid derivative, and 0.1-0.3 parts of sodium copper chlorophyllin. The physical sun-screening agent is at least one of nano titanium dioxide and nano zinc oxide. When the polyglutamic acid, the sophora flower extract, the physical sun-screening agent, the ascorbic acid and/or the ascorbic acid derivative and the sodium copper chlorophyllin have a synergistic effect, the prepared sun-screening composition has a very good function of resisting ultraviolet UVA (320-400 nm) and ultraviolet UVB (290-320 nm) and a very good blue light protection effect.
