Why HPMC has thickening ability?
What is hydroxypropyl methyl cellulose?
Hydroxypropyl methyl cellulose is a semi-synthetic, inactive, viscoelastic polymer, often used as a lubricant in ophthalmology or as an adjunct or excipient in oral medicine—white or quasi-white fibrous or granular powder. Solid is flammable and incompatible with strong oxidants. Solubility: soluble in water and some solvents, such as the appropriate proportion of ethanol/water, propanol/water, etc. The aqueous solution has surface activity, high transparency, and stable performance. The gel temperature of products of different specifications are different, and the solubility changes with the viscosity. The lower the viscosity, the greater the solubility. The performance of HPMC of different specifications is somewhat different, and the dissolution of HPMC in water is not affected by the pH value.
Is HPMC harmful to human body?
Hydroxypropyl methylcellulose (HPMC) is a cellulose derivative with many uses. As a pharmaceutical excipient, it has been used as a framework material for drug release alone or as an auxiliary material for regulating drug release in recent years. It has also been used as a coating material for drugs. In addition, it has also been used as a tackifier, adhesive, etc. Hydroxypropyl methylcellulose added to drugs is the standard of pharmaceutical grade, so there is no need to worry.
The role of HPMC in chemical industry
1. Polymerization of vinyl chloride and vinylidene: as a suspension stabilizer and dispersant during polymerization, it can be used together with vinyl alcohol (PVA) hydroxypropyl cellulose (HPC) to control particle shape and particle distribution
2. Adhesive: As the adhesive for wallpaper, instead of starch, it can usually be used together with vinyl acetate emulsion paint
3. Pesticide: added to pesticides and herbicides, it can improve the adhesion effect during spraying
4. Latex: emulsifying stabilizer for improving asphalt latex, thickener for styrene-butadiene rubber (SBR) latex
5. Binder: used as the forming adhesive for pencils and crayons.
Price of hydroxypropyl methyl cellulose
Hydroxypropyl methylcellulose particle size and purity will affect the product's price, and the purchase volume can also affect the cost of hydroxypropyl methylcellulose. A large amount of large amount will be lower. The price of hydroxypropyl methylcellulose can be found on our company's official website.
