Abstract

The invention discloses a novel composite sun-screening agent nano-structure lipid carrier. The carrier is loaded with two active ingredients, i.e., ethylhexyl triazone and diethylaminohydroxylbenzoylhexyl benzoate, and is characterized in that: the nano-structure lipid carrier comprises the following components in percentage by weight: 1-10 percent of ethylhexyl triazone, 2-20 percent of diethylaminohydroxylbenzoylhexyl benzoate, 3-15 percent of an emulsifying agent, 10-15 percent of a composite lipid material and the balance of deionized water, wherein the composite lipid material is a mixture of a solid lipid material and a liquid lipid material, and is selected from at least one of the following compounds: caprylic capric triglyceride, acetylated monoglyceride, glycerin monostearate, grape seed oil and glyceride L. The nano-structure lipid carrier has high stability; and a preparation method of the nano-structure lipid carrier is simple and controllable, has high repeatability, and can be applied to preparation of a cosmetic containing ethylhexyl triazone and diethylaminohydroxylbenzoylhexyl benzoate.

Description

technical field [0001] The invention belongs to the technical field of carrier systems in cosmetics preparation technology, relates to a nano-scale carrier and a preparation method thereof, in particular to a drug active drug containing ethylhexyl triazone and diethylamino hydroxybenzoyl hexyl benzoate Ingredient nanostructured lipid carriers and methods for their preparation. Background technique [0002] Sunscreen cosmetics are a hot spot in the development of the global cosmetics industry in recent years. With the improvement of people's living standards, the requirements for the design of sunscreen products have also developed from UVB protection to organic molecule protection that takes into account UVA. [0003] SPF is the protection against UVB in sunscreen cosmetics. Generally speaking, the SPF of the lowest sunscreen products is SPF2-6, the medium sunscreen product is SPF6-8, the high-end sunscreen product is SPF8-12, and the products with SPF value in the range o...
