Problems solved by technology

However, it is limited to the study of chemical sunscreens formed by coating with a single methoxycinnamate, and its photostability and ability to absorb ultraviolet rays still cannot achieve the effect of high-efficiency sunscreens
[0005] However, regarding the coated sunscreen composition obtained by compounding ethylhexyl methoxycinnamate, hexyl diethylaminobenzoyl benzoate, and ethylhexyl triazone according to specific compounding weight parts, its light There is no relevant report on the research on the stability and the ability to absorb ultraviolet rays that have been significantly improved.

Abstract

The invention discloses a coated sunscreen composition, which is characterized by comprising the following components in parts by weight: 26-30 parts of ethylhexyl methoxycinnamate, 6 to 10 parts of diethylamino hydroxybenzoyl hexyl benzoate; and 3 to 5 parts of ethyl hexyl triazinone. The coating sunscreen composition is prepared by compounding the ethylhexyl methoxycinnamate, the diethylaminohydroxybenzoyl hexyl benzoate and the ethyl hexyl triazinone according to the specific parts by weight, the light stability and the ultraviolet ray absorption capacity are obviously improved, the coated sunscreen composition is added into a sun-screening cream formula, and the specific contents of the DNA-containing emollient, the emulsifier, the thickener, the common sun-screening agent, the skin conditioner, the humectant, the preservative and the antioxidant are compounded, the SPF value and the PA value of the prepared sun-screening cream are obviously increased, and the biological sun-screening effect is achieved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a coating sunscreen composition and a sunscreen composed thereof. Background technique [0002] Sunscreen has always been a topic of concern in the field of cosmetics, and the stability, safety, and effectiveness of sunscreens are issues that must be solved for sunscreens. Commonly used sunscreens mainly include chemical sunscreens and physical sunscreens according to the mechanism. Chemical sunscreens achieve sun protection by absorbing ultraviolet rays, converting them into energy and releasing them; physical sunscreens achieve sun protection by shielding ultraviolet rays through reflection. Chemical sunscreens are divided into UVA (320-400nm) and UVB ultraviolet absorbers (290-320nm) according to the different ultraviolet absorption bands. Most chemical sunscreens are ostracized by the public because they are unstable and irritating to the skin. By using solid lipid nanop...
