Hydroxypropyl methylcellulose is a white, odorless and tasteless powder with different solubility in cold water and hot water. Products with high methoxyl content are insoluble in hot water above 85°C. Products with medium methoxyl content are insoluble in hot water above 65°C. Products with low methoxyl content are insoluble in hot water above 60°C. Ordinary

According to the application needs of the product, there are usually very wide requirements for the viscosity and purity of HPMC. Under the same degree of substitution, the viscosity has a certain effect on the gel temperature: the lower the viscosity, the higher the gel temperature; the higher the viscosity, the lower the gel temperature.

Ash content and quality of hydroxypropyl methylcellulose

What is the ash content of hydroxypropyl methylcellulose? Ash, also known as scorch residue, is simply understood to be the impurities contained in the product. It occurs naturally during the production process. After the product has come out of the etherification reactor, it enters the neutralisation kettle, where the pH value is first adjusted to
