Soothing and repairing composition and preparation method thereof

Abstract

The invention provides a soothing and repairing composition and a preparation method thereof. The soothing and repairing composition is prepared from the following raw materials in parts by weight: 0.5 to 3.0 parts of tetrahydrocurcumin or curcumin, 0.01 to 0.5 part of paeonol, 0.01 to 3 parts of glycyrrhizic acid or 18 beta-glycyrrhetinic acid, 0.01 to 1 part of an extract of Glycyrrhiza inflata Bat., 0.1 to 10 parts of bisabolol, 0.2 to 10 parts of 4-tert-butyl cyclohexanol, 0.5 to 20 parts of panthenol and 0.001 to 1.5 parts of water-soluble protein, wherein the purity of the water-soluble protein is 90 to 98%. According to the soothing and repairing composition provided by the invention, the ratio is adjusted; a soothing agent dissolved by the water-soluble protein and polyol is used; a mixing technology of the soothing agent and a water-soluble protein solution is improved; under a proper stirring condition, the temperature is controlled so that the soothing agent dissolved by the polyol and the water-soluble protein can be dissolved very well and are not separated out, and the effect of the composition is facilitated; the soothing and repairing composition can be used for soothing subjective symptoms including inflammation, stabbing pain and the like and has a relatively strong anti-allergic effect; and effective active components in the composition are scientifically proportioned and have a synergistic effect.

Problems solved by technology

[0008] In actual experiments, it was found that the above-mentioned active ingredients could not be added in an amount of 20mg / ml at room temperature at 25°C, and crystals would precipitate out. If you want to add a high content to the product, you need a large amount of polar solvents, such as dipropylene glycol , DMSO, which is difficult to apply in the actual development process of the formula, and because the active ingredient is slightly soluble in water or insoluble in water, it is necessary to add a higher content of ethanol or DMSO and other polar solutions, such solvents will make sensitive skin The skin barrier damage of people with sensitive skin is more serious, and this solution is difficult to apply to the formulation development of skin care products, and it is not suitable for the skin characteristics of sensitive skin groups
