Problems solved by technology

Turmeric (CURCUMA LONGA) root extract (CAS No.: 84775-52-0) is obtained by extracting the turmeric oil fraction from turmeric tubers. The main active ingredient is curcumone, which has significant antioxidant and anti-inflammatory capabilities, and weakens UV rays. Redness and swelling caused by irradiation, but it is easy to change color and taste, which affects its use in formulas; Rutin (RUTIN, CAS No.: 153-18-4), which belongs to flavonoids, has an absorption effect on ultraviolet rays. It can also remove active oxygen free radicals produced by cells, but its solubility is poor and it is easy to change color; 350nm ultraviolet light has a strong absorption effect, and also has anti-oxidation and anti-inflammatory effects. It is easy to decompose when exposed to light and heated, and it is inconvenient to use; caffeic acid (CAFFEIC ACID, CAS No.: 331-39-5), in the form of chlorogenic acid It exists in plants such as coffee, can absorb ultraviolet rays, and has a wide range of antibacterial, anti-inflammatory, and anti-oxidative activities, but it has disadvantages such as easy inactivation and change of taste

Abstract

The invention relates to a sun-proof and synergistic microcapsule powder which is characterized by comprising the following components in percent by mass: 40.0 to 48.0 percent of a wall material, 20.0to 24.0 percent of a compound emulsifier, and 32.0 to 36.0 percent of a sun-proof and synergistic composition, wherein the wall material is composed of maltodextrin, acacia senegal gum and gelatin ina mass ratio of 3.0-5.0 to 5.0-8.0 to 12.0-17.0; the compound emulsifier is composed of sucrose polystearate, sodium stearoyl lactylate and polyglyceryl-10 pentastearate in a mass ratio of 2.5-4.0 to0.1-0.3 to 1.5-2.5; the sun-proof and synergistic composition is composed of a turmeric root extract, rutin, ferulic acid and caffeic acid in a mass ratio of 5.0-10.0 to 8.0-15.0 to 15.0-25.0 to 3.0-8.0. The sun-proof and synergistic microcapsule powder provided by the invention can load the turmeric root extract, the rutin, the ferulic acid and the caffeic acid simultaneously and improve the stabilities thereof, has a sun-proof effect, and has the advantages of high stability and convenience in use.

Description

technical field [0001] The invention relates to the technical field of sunscreen cosmetics, in particular to a sunscreen synergistic microcapsule powder and a preparation method thereof. Background technique [0002] Ultraviolet (UV) wavelengths can be divided into three types: UVC (100nm-280nm), UVB (280nm-320nm) and UVA (320nm-400nm). UVC is completely absorbed when it passes through the ozone layer. UVB can penetrate the ozone layer and enter the earth's surface, mainly acting on the epidermis of the skin to cause erythema. [0003] Some of the chemical sunscreens currently used in cosmetics have poor photostability, and are prone to photoinduced degradation when exposed to sunlight, reducing UV protection efficiency and causing some skin discomfort. The sunscreen synergistic ingredients derived from natural plants are not only highly safe, but also have a sunscreen synergistic effect. Turmeric (CURCUMA LONGA) root extract (CAS No.: 84775-52-0) is obtained by extracting...
