Abstract

The invention relates to a preparation method of temperature-sensitive type chitosan-based anti-acne aquagel for cosmetics. The method is characterized by comprising the following steps of (1) preparing a chitosan water solution; (2) preparing a beta-sodium glycero-phosphate water solution; (3) under the 3-5 DEG C water bath condition, mixing the chitosan water solution and the beta-sodium glycero-phosphate water solution according to the mass ratio of (1 to 5):1 to obtain the chitosan / beta-sodium glycero-phosphate water solution; (4) preparing an alpha-mangostin ethanol solution; (5) preparing a genipin-aucubin water solution; (6) mixing the chitosan / beta-sodium glycero-phosphate water solution and the alpha-mangostin ethanol solution according to a mass ratio of (20 to 100):1 to preparethe alpha-mangostin-chitosan / beta-sodium glycero-phosphate water solution; (7) performing crosslinking on the alpha-mangostin-chitosan / beta-sodium glycero-phosphate water solution and the genipin-aucubin water solution according to the mass ratio of (100 to 200):1 at 78 to 80 DEG C to obtain the anti-acne aquagel. The preparation method has the advantages that the preparation process is simple; safety and nontoxicity are realized; the obtained anti-acne aquagel has a good anti-acne effect and high safety; the use is convenient, and the like.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a preparation method of a temperature-sensitive chitosan-based acne-removing hydrogel for cosmetics. Background technique [0002] Modern people have various skin problems due to climate problems, environmental pollution, sub-health problems and many other factors, among which acne problems account for a large proportion. According to authoritative statistics from the Ministry of Health in 2017, consumers with acne problems in my country are With an increase of 4-6 million person-times per year, effective acne treatment has become an important topic in the study of problematic skin in recent years. [0003] Excessive sebum secretion, abnormal keratinization of hair follicles, and stimulation of anaerobic bacteria in hair follicles can lead to acne. The current methods of treating acne mainly contain oral drug method and topical application method. The oral drug method is mainl...
