Synchronous repair and sunscreen composite nano emulsion for skin injury from ultraviolet A radiation and ultraviolet B radiation and method for preparing same

Abstract

The invention relates to a synchronous repair and sunscreen composite nano emulsion for skin injury from ultraviolet A radiation and ultraviolet B radiation and a method for preparing the same. The product is prepared from the following raw materials in percentage by mass: 9.0 to 13 percent of isopropyl myristate, 25.0 to 33 percent of caprylocaproyl macrogolglyceride, 8.5 to 15 percent of polyglyceryl fatty acid ester, 33 to 46 percent of triple distilled water, 0.002 to 0.004 percent of superoxide dismutase, 0.25 to 0.4 percent of glutathione, 1 to 3 percent of vitamin E, 1.5 to 3 percent of coenzyme Q10, 0.8 to 1.6 percent of 1-(4-tert-butylphenyl)-3-(4-methoxyphenyl)propane-1,3-diketone, 2.0 to 5.0 percent of ethylhexyl methoxycinnamate, 0.6 to 2.0 percent of 4-methyl benzylidene camphor, 0.03 to 0.2 percent of ethylene diamine tetraacetic acid, 0.05 to 0.3 percent of citric acid and 0.5 to 2.0 percent of sodium citrate. The composite nano emulsion greatly improves the stability, safety and sunscreen effect of the sunscreen functional ingredient, can prevent the skin from being further damaged by the ultraviolet radiation and synchronously achieve the repair effect while serving as sunscreen.

Description

technical field [0001] The invention relates to the preparation of sunscreen and repair products after the new preparation technology is improved, especially refers to the synchronous repair of mid- and long-wave ultraviolet skin damage and sunscreen composite nanoemulsion and its preparation method. Background technique [0002] Atmospheric ozone layer blocks 99% of ultraviolet radiation in sunlight, protecting all creatures on the earth from strong ultraviolet rays. Since the Antarctic ozone hole was first reported in 1985, atmospheric ozone depletion has become one of today's global environmental problems. The chemical stability of chlorofluorocarbons released into the environment is high, and the retention time in the atmosphere can be as long as 40 to 150 years. After these compounds reach the stratosphere through the troposphere, they are decomposed by high-energy ultraviolet radiation, and the chlorine atoms produced by the decomposition react with ozone molecules to...

AI Technical Summary

Problems solved by technology

[0018] 1. In order to overcome the shortcomings existing in the current background technology: (1) chemical sunscreens will decompose and fission under the action of ultraviolet rays, and the photostability is not high. For example, benzophenone and its derivatives have general oxygen resistance and need to be added Antioxidants; methane derivatives, suitable for products with higher sun protection factor, but poor photostability, greatly degraded after ultraviolet irradiation, greater irritation to the skin, and strong allergies
