1, 2-hexadiol is a kind of polyol, the appearance is colorless and transparent, has a mild sweet fragrance, as a cosmetic raw material, has a good bactericidal and moisturizing effect (antibacterial mechanism: can enter the cell membrane of microorganisms, and then destroy the integrity of the cell membrane, let the cell fluid penetrate out, and finally lead to the death of microorganisms), while no sensitive side effects on human skin. 1, 2-hexadiol structural formula 1, 2-hexadiol has good miscibility with other substances (easily soluble in water, ethanol, etc.), and can be well combined with other anti-microbial substances to play an antibacterial and anti-sensitive role. In addition, there are also reports that 1, 2-hexanediol is used in deodorant, which has obvious deodorizing and antiperspirant effect on human skin, and is gentle to the skin. It is precisely because 1, 2-hexadiol has antibacterial effects and is not on the list of preservatives…

Polyvinylpyrrolidone acts as a moisturizing agent for the skin. Polyethylpyrrolidone (PVP for short) is a non-ionic polymer compound, which has good affinity to the skin and can form a non-occlusive film on the skin surface, thus playing the role of moisturizing and moisturizing. If PVP is added to the mask, it can reduce the greasy feeling, and has a good soft and smooth feeling, which can speed up the penetration of the mask ingredients and extend the retention time of the ingredients. Polyvinylpyrrolidone knowledge expansion Polyvinylpyrrolidone is the most distinctive and widely studied fine chemical among n-vinylamide polymers. Has developed into non-ionic, cationic, anion 3 categories, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular mass from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used. PVP is divided into four stages according to its…

First, medicine and health; Second, food processing; Third, detergent; Fourth, paints and pigments; Fifth, polymer technologyMedicine and health PVP has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility, and does not form any irritation to the skin, mucous membranes, eyes, etc. 2 Food processing PVP itself is not carcinogenic, has good food safety, can form complexes with specific polyphenol compounds (such as tannins), and is mainly used as a food clarifying agent and stabilizer in food processing such as beer, juice, wine. 3 abluent PVP has anti-fouling reprecipitation performance, can be used to prepare transparent liquid or heavy dirt detergent, adding PVP in detergent has a good anti-color effect, and can enhance the cleaning ability, washing fabrics can prevent synthetic detergent on the skin stimulation, especially for synthetic fibers, this performance is more prominent than carboxymethyl cellulose (CMC) detergent.

Polyvinylpyrrolidone (PVP) was first synthesized by the German company BASF during World War II as an artificial plasma solubilizer. In the pharmaceutical industry, PVP and cellulose derivatives, acrylic compounds are currently internationally recognized as the most important three kinds of synthetic pharmaceutical excipients, whose average molecular weight is generally expressed by the K value of K-15, K-30, K-60, K-90 and other representative molecular weight of about 10,000, 40,000, 160,000, 360,000. PVP has many excellent properties such as solubility, solubilization, film forming, complexation, adhesion and certain surface activity, especially good biocompatibility without any irritation to the skin, mucous membranes and eyes, so it is widely used in the field of medicine. 1 Used as an adhesive Because PVP is soluble in both water and some common organic solvents, such as ethanol, it can be used in a variety of formulations. For example, the influence of water and heat can be eliminated…
