Double-layer water preparation containing oil-controlling starch particles, and preparation method thereof

Abstract

The invention discloses a double-layer water preparation containing oil-controlling starch particles. According to a preparation method, two kinds of starch particles with different densities and hydrophilic performance are adopted, so that suspension of the oil-controlling starch particles in the double-layer water preparation is realized, deposition of starch is not easily caused, and excellent oil controlling effect is realized. The invention also discloses the preparation method of the double-layer water preparation containing oil-controlling starch particles. According to the preparation method, cassava starch, polymethylsilsesquioxane, and hydroxypropyl starch phosphate are add at last so as to prevent starch gelatinization, control the stirring time of hydroxypropyl starch phosphate, ensure complete powder hydration, and avoid generation of excess foam, and it is convenient for filling in a later period.

Description

technical field [0001] The invention relates to a composite preparation, in particular to a double-layer water preparation containing oil-controlling starch granules and a preparation method thereof, which is suitable for the fields of medicine and personal care. Background technique [0002] Acne vulgaris is a chronic inflammatory disease of the pilosebaceous glands, characterized by comedones, papules, pustules, nodules, cysts, and scars. It is often accompanied by seborrhea and occurs mostly in adolescent men and women. Timely treatment can improve skin beauty and prevent secondary infection. The onset of acne is related to the increased secretion of androgen in the body during puberty, hypersecretion of sebaceous glands, keratinization of the infundibulum of hair follicles and ducts of sebaceous glands, and the proliferation of Propionibacterium acnes in hair follicles. [0003] Mechanism and formation process of acne: [0004] 1. The formation of acne The increase of ...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a double-layer water formulation containing oil-controlling starch granules. By introducing oil-controlling starch, the formula cost is more advantageous under the premise of achieving a good oil-controlling effect, and it also solves the problem of Simple addition of starch, sinking, agglomeration, and technical problems that cannot be dispersed. The formula is designed from the four aspects of correcting abnormal keratinization of pores, antibacterial, anti-inflammatory, and oil control. It has the effects of oil control and acne removal.
