Abstract

The invention discloses nano-zinc oxide sun-blocking cream. The sun-blocking cream comprises the following components in parts by mass: 6-10 parts of zinc oxide powder with grain diameter of 100-285nm, 8-13 parts of titanium dioxide powder with grain diameter of 297-500nm, 10-30 parts of monostearate glyceride, 10-13 parts of white oil, 4-6 parts of vaseline, 4-8 parts of dehydrated sorbitan sesquioleate, 7-9 parts of cetanol, 3-7 parts of bee wax, 5-13 parts of glycerinum, 7-10 parts of deionized water, 4 parts of triethanolamine, 1-3 parts of methylparaben and 10-13 parts of traditional Chinese medicine extracted essential solution, wherein the traditional Chinese medicine extracted essential solution with mass percentage of 40 percent is prepared from Chinese angelica, polygonum multiflorum, ginseng, saffron, angelica root, cassia twig and coix seed through superfine grinding, decocting, filtering and concentrating steps.

Description

technical field [0001] The invention relates to a nano-zinc oxide sunscreen, in particular to a nano-zinc oxide sunscreen which blocks ultraviolet rays harmful to skin and retains ultraviolet rays beneficial to human beings. Background technique [0002] Sunscreen refers to cosmetics that add sunscreen agents that can block or absorb ultraviolet rays to prevent skin from being tanned and sunburned. [0003] Specifically, sunscreens that block ultraviolet rays generally refer to physical sunscreen ingredients. Its principle is like wearing an umbrella and hat, which can reflect the ultraviolet rays irradiating the human body. The main ingredients are zinc oxide, titanium dioxide, and physical sunscreen powder 280- 370nm (protects UVA), physical sunscreen powder 250-340nm (protects UVB). UV-absorbing sunscreens generally refer to chemical sunscreen ingredients, which can absorb the energy of ultraviolet rays and undergo chemical reactions. [0004] Ultraviolet rays in sunlig...
