The invention discloses a quick-drying adhesive and a preparation method thereof. The quick-drying adhesive consists of the following raw materials in parts by weight: 20 to 60 parts of modified ester cyanopentadienoate, 40 to 70 parts of isononyl isononanoate, 8 to 10 parts of aluminum starch octenylsuccinate, 10 to 20 parts of polypropylsilsesquioxane, 10 to 20 parts of lauroyl lysine, 6 to 10 parts of silane coupling agent, 1 to 8 parts of phenolic compound and 20 to 60 parts of deionized water. The preparation method includes the following steps: the modified ester cyanopentadienoate, the isononyl isononanoate, the aluminum starch octenylsuccinate and the deionized water are mixed and heated to 30 DEG C to 50 DEG C; the silane coupling agent and the phenolic compound are added, reaction takes place under 70 DEG C to 75 DEG C for 5 to 6 minutes, the other components are added and uniformly mixed, reaction takes place under 30 DEG C to 50 DEG C for 20 to 30 minutes, and cooling is carried out. The adhesive disclosed by the invention has good anti-freezing property, can be put under the condition of -30 DEG C for seven days without being frozen, and can be quickly dried and solidified.

The present invention relates to spherical zinc oxide, a manufacturing method thereof and a cosmetic composition comprising the same. More specifically, the present invention relates to a spherical zinc oxide powder coated with natural materials, comprising a spherical zinc oxide powder having an aspect ratio of 1 to 1.5; a tetraethyl orthosilicate (TEOS) coating layer coated with TEOS on the surface of the spherical zinc oxide powder; and a natural material coating layer coated on the surface of the TEOS coating layer, wherein the TEOS coating layer is a uniform single layer, and the naturalsubstance coating layer is a coating layer formed by coating one or more substances selected from a group consisting of lauroyl lysine, cocoa butter, lecithin and stearic acid. According to the present invention, it is possible to provide the spherical zinc oxide powder coated with natural materials having excellent UV blocking effect as well as excellent usability, dispersibility, stability and safety for the human body; a manufacturing method thereof; and a cosmetic composition comprising the same.

The invention relates to a preparation method of epsilon-N-lauroyl lysine. In the method, lysine or a salt thereof and lauroyl chloride are taken as raw materials. The method comprises the following steps of: making lysine or a salt thereof and a divalent metal ion form a chelate for protecting alpha-amino and carboxyl; undergoing an amidization reaction on the chelate and lauroyl chloride; and damaging a chelate structure through acid hydrolysis, and deprotecting alpha-amino and carboxyl to obtain the epsilon-N-lauroyl lysine. According to the method disclosed by the invention, an entire operating process is simple and convenient, reaction directional property is definite, a small quantity of side products are produced, high-purity epsilon-N-lauroyl lysine (more than or equal to 98.5 percent) can be obtained, and the obtained product can be applied in the field of cosmetics.
