Modern women's makeup is very common. It is human nature to love beauty. In addition, makeup can give us a lot of benefits, such as: 1 The first time people meet each other is often impressive. And everyone can't be perfect, now we can use makeup to make up for some of our natural defects, make ourselves more beautiful, and at the same time make people more confident. 2 make up beautiful and make your life full of enthusiasm and positive energy. 3, business women, learn to wear light makeup, meet with customers, is also a kind of respect and courtesy to the other party, dressed neatly, talk generously, naturally will show the connotation of temperament and self-confidence. However, there are also many skin problems caused by makeup: dull skin caused by stimulation, residual cosmetics, incomplete makeup removal, excessive cleaning, etc. Have you been recruited for these problems? Make-up of skin dull, heavy metal residues, skin color deepen we and want to beautiful do? Cosmetic manufacturer oem takes you to understand the role of chitosan. Chitosan, also known as chitosan, deacetylated chitin, deacetylated chitin, soluble chitin and soluble chitin. Amorphous solid than optical rotation [Alpha]D11-3 ° ~ 10 °. Tasteless, non-toxic, easy to degrade, is a rare natural cationic polyelectrolyte. It is soluble in low acidity aqueous solution, has good biocompatibility and no antigenicity. Chitosan is widely used in medicine, mainly including: ① killing parasites and inhibiting bacterial activity; (2) making medical fibers and membranes, such as surgical sutures, Medical fiber paper and membranes, artificial kidney membranes, artificial skin, etc; (3) used as drug carrier, such as sustained-release film and sustained-release gel; ④ Anti-tumor; ⑤ As coagulant and anticoagulant; 6 for ophthalmic materials, such as contact lenses, contact lenses; ⑦ Lipid-lowering and cholesterol-lowering; ⑧ Acid and anti-ulcer. Chitosan has a wide range of antibacterial effects, and its antibacterial effects mainly include the following two mechanisms: One is that chitosan forms a polymer membrane by adsorbing on the cell surface to prevent the transportation of nutrients into cells, thereby playing a bacteriostatic and bactericidal role; Another mechanism is that chitosan penetrates into the cell body, adsorbs the cytoplasm with anions in the cell body, and flocculates to disturb the normal physiological activities of the cell, thus killing bacteria. Because the cell wall structures of gram-positive bacteria and gram-negative bacteria are different, the two effects have different degrees of influence on them, so chitosan with different relative molecular weights has different antibacterial mechanisms. Chitosan is the only basic amino polysaccharide that exists in large quantities in natural polysaccharides. It has a series of special functional properties and has extensive and important application value in agriculture and food. It is rich in sources, the preparation and film formation are simple and the preservation performance is superior, which will play an increasingly important role in food preservation and other aspects. In addition, chitosan has the functions of enhancing human immunity, removing excess fat in the body, inhibiting harmful bacteria, reducing blood lipid, regulating blood sugar, non-toxic anti-cancer effect and serving as biomedical materials. Studies have shown that chitosan can adsorb heavy metals such as cadmium, mercury and copper, and can be used as flocculating various colloidal particles for Juice Clarification, sucrose purification, wastewater treatment, protein mycelium flocculation, etc. In addition, chitosan has good application prospects in medicine due to its advantages of biofunctionality, safety, non-toxicity, biodegradability and biocompatibility. Chitosan has the functions of improving immunity, activating cells, preventing cancer, reducing blood lipid, lowering blood pressure, resisting aging, regulating body environment, etc. It can be used in the fields of medicine, health care and food. In the field of environmental protection, chitosan can be used for sewage treatment, protein recovery, water purification, etc. In the field of functional materials, chitosan can be used for membrane materials, carriers, adsorbents, fibers, medical materials, etc.
