Abstract

The invention discloses a sun-screening composition containing sucrose acetate iso-butyrate. The sun-screening composition containing sucrose acetate iso-butyrate comprises the following raw materialsin percentage by mass of 30-70% of a solid inorganic sun-screening agent, 10-67% of an organic sun-screening agent and 3-20% of a dispersing agent, wherein the dispersing agent is sucrose acetate iso-butyrate. The invention also discloses a preparation method of the sun-screening composition. The preparation method comprises the steps of respectively pouring the organic sun-screening agent and the dispersing agent to a reaction kettle, raising the temperature to 45-60 DEG C, performing uniform stirring, then pumping the solid inorganic sun-screening agent, performing uniform stirring, performing homogenizing, performing filtration, and performing impurity removal so as to obtain the sun-screening composition. The sun-screening composition disclosed by the invention is low in cost and simple in preparation method, and is suitable for large-scale industrial production; and when the sun-screening composition is applied to emulsifying type cosmetics, the phenomenon of oil seepage of an instable formula can be improved, and the product stability can also be correspondingly increased.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a sunscreen composition containing sucrose acetate isobutyrate and a preparation method thereof. Background technique [0002] Sucrose Acetate Iso-butyrate, English name: Sucrose Acetate Iso-butyrate, SAIB, a sucrose derivative, in the sucrose molecule, 8 hydroxyl groups are substituted by isobutyryl and acetyl sucrose ester, that is, isobutyryl and acetyl Mixed sucrose ester of (acid) containing several different isomers. Because the ratio of acetate to isobutyrate is about 2:6, it is also called Sucrose Diacetate Hexaisobutyrate. It is a clear viscous liquid with a mellow taste and smell. It solidifies below 30°C, becomes a semi-fluid viscous liquid at 30-40°C, and becomes a flowable liquid above 40°C. Insoluble in water, easily soluble in most organic solvents, such as aromatic hydrocarbons, aliphatic ketones, ketones, etc. Relative density 1.14-1.15, is an excellent den...
