pvp is polyvinylpyrrolidone. Polyvinylpyrrolidone (PVP) is a kind of non-ionic polymer compound. PVP is made from vinyl pyrrolidone (NVP) by bulk polymerization and solution polymerization. In the process of bulk polymerization, due to the viscosity of the reaction system, the polymer is not easy to diffuse, and the polymerization heat is not easy to remove, resulting in local overheating. Therefore, the obtained product has low molecular weight, high content of residual monomer, and is mostly yellow, and has no great practical value. Solution polymerization is generally used to synthesize PVP in industry. There are two main routes for the production of PVP polymerization, the first is the solution polymerization of N-2-pyrrolidone (NVP) in organic solvents, followed by steam stripping. The second route is aqueous polymerization of NVP monomer with water-soluble cation, anionic or non-ionic monomer. A crosslinked homopolymer of pure vinylpyrrolidone. Polyvinylpyrrolidone (PVP) has the ability to bind to a…

The main role of polyvinylpyrrolidone in cosmetics is to increase the stability, consistency and moisturizing effect of the product. It is a non-ionic polymer compound with good water solubility and high viscosity, which can increase the viscosity and adhesion of cosmetics, making it easier for cosmetics to adhere to the skin. ‌ Polyethylene pyrrolidone is generally used in cosmetics, has a good affinity, can help adjust the state of the skin, the stimulation of the skin is relatively small, but also can achieve the role of moisturizing, can effectively help improve the state of the skin, can adjust the personal skin condition. Polyvinylpyrrolidone is widely used, is a kind of separation of polymer compounds, if they belong to the allergic physique, in the first use may have an allergic reaction, should be closely observed the use of the situation, but also to avoid long-term use, polyvinylpyrrolidone can also be added…

I. Chemical properties of polyvinylpyrrolidonePolyvinylpyrrolidone is a colorless and odorless linear polymer, white powder at room temperature. Its chemical structure contains rich pyrrolidone ring, has a fairly stable hydrophilicity, can absorb the surrounding water molecules, form a moisturizing film, effectively improve the skin moisture protection. In addition, polyvinylpyrrolidone also has good solubility and adhesion, and does not clog pores. Second, the application of polyethylene pyrrolidone in skin care cosmeticsPolyvinylpyrrolidone is widely used in cosmetics, usually as a moisturizer, adhesive, thickener, emulsifier and other functional ingredients. Adding polyvinylpyrrolidone to skin care products can have the following effects: 1. Moisturizing effect Polyvinylpyrrolidone has the property of absorbing surrounding water molecules, which can form a moisturizing film and effectively reduce water loss. Therefore, adding it to products such as creams, lotions, and facial masks can improve the moisturizing properties of products. 2. Antioxidant effect Polyethylpyrrolidone also has certain antioxidant capacity, which can prevent…

At present, about 40% of the drugs used on the market are insoluble drugs, because they are difficult to absorb and utilize in the human body, and the use of drugs is limited to a certain extent. In order to increase the dissolution and absorption of insoluble drugs, researchers have developed many methods from various aspects of pharmaceutical and pharmaceutical, such as drug salting, micropulverization, cyclodextrin inclusion, preparation of amorphous, Solid dispersion, and Co-crystal (co-precipitation Co-precipitate). Among the preparation of drug co-precipitation, drug-polyvinylpyrrolidone co-precipitation is one of the most studied.
