Hydroxypropyl methylcellulose can be used in daily chemical products such as toothpaste, shampoo, shower gel, hand soap, shoe polish, etc. It has the function of thickening and preventing precipitation.
Products similar to hydroxypropyl methylcellulose HPMC include hydroxymethylcellulose CMC, ethylcellulose EC, hydroxypropylcellulose HPC, methylhydroxyethylcellulose MHEC, methylhydroxypropylcellulose MHPC , Hydroxyethylcellulose HEC. Among these products, hydroxyethyl cellulose ether has the best effect in the field of daily chemicals. Why? The technical department now provides the following explanation.
Daily chemical grade 200,000S viscosity hydroxypropyl methylcellulose is white or slightly yellow powder, odorless, tasteless and non-toxic. Soluble in cold water and mixed with organic solvents to form a transparent viscous solution. The aqueous solution has surface activity, high transparency and strong stability, and is not affected by the pH value when dissolved in water. Daily chemical grade hydroxypropyl methylcellulose has thickening and antifreeze properties in shampoos and shower gels, and has water-retaining and film-forming properties for hair and skin. With the substantial increase in basic raw materials, cellulose (antifreeze thickener) can also be used in shampoos and shower gels, greatly reducing costs and achieving ideal results. From the perspective of stability and basic performance, HEC is stronger than other products in the application of daily chemical products.
Hydroxypropyl methylcellulose as nonionic surfactant. It has the functions of thickening, suspension, bonding, flotation, film formation, dispersion, water retention and providing protective colloid. These properties include the protective and water-retaining effects of colloids. The application in the field of daily chemicals is very important.
Daily chemical grade special 200000S viscosity is soluble in hot and cold water, but generally insoluble in most organic solvents. It does not settle at high temperatures or boiling, giving it a wide range of solubility and viscosity properties. Also non-thermally gelable. The effect of thickening is minimal. HPMC stability is excellent.
In the application of hydroxypropyl methylcellulose ether in the field of daily chemicals, HPMC is widely used as a thickener, emulsifier and adhesive in daily necessities due to its excellent properties. When using mother liquor, HPMC should be sieved into a certain amount of water during the mixing process and should not be shoveled or poured out. Do not stop stirring until a clear, smooth stock liquor is obtained. Do not add other substances to avoid affecting the pH value of the system. Want to better improve product quality. It is recommended to appropriately increase the temperature and pH value of the system.
