Daily chemical grade hydroxypropyl methylcellulose HPMC
Hydroxypropyl methylcellulose is a non-ionic cellulose ether made from natural polymer material (cotton) cellulose through a series of chemical processes. It is an odorless, tasteless white powder that swells into a clear or slightly cloudy colloidal solution in cold water. It has thickening, bin...Read more -

Quality Identification of Hydroxypropyl Methyl Cellulose
one. The difference between adulterated hydroxypropyl methylcellulose (HPMC) and pure hydroxypropyl methylcellulose (HPMC) 1. Appearance: Pure hydroxypropyl methylcellulose HPMC looks fluffy and has a low bulk density, ranging from 0.3-0.4g/ml; adulterated hydroxypropyl methylcellulose HPMC has b...Read more -
Application of Carboxymethyl Cellulose in Food Industry
Carboxymethylcellulose (CMC) is synthesized from fibers (fly/short lint, pulp, etc.), sodium hydroxide, and monochloroacetic acid. According to different uses, CMC has three specifications: pure product purity ≥ 97%, industrial product purity 70-80%, crude product purity 50-60%. CMC has excellent...Read more -
Functional Properties of CMC (Carboxymethyl Cellulose)
Carboxymethyl cellulose (sodium carboxyme thyl cellulose, CMC) is a carboxymethylated derivative of cellulose, also known as cellulose gum, and is the most important ionic cellulose gum. CMC is usually an anionic polymer compound prepared by reacting natural cellulose with caustic alkali and mono...Read more -
Preparation of carboxymethyl cellulose
Carboxymethyl Cellulose (English: Carboxymethyl Cellulose, CMC for short) is a commonly used food additive, and its sodium salt (sodium carboxymethyl cellulose) is often used as a thickener and paste. Carboxymethyl cellulose is called industrial monosodium glutamate, which is widely used in indus...Read more -
Dissolution and Dispersion of Carboxymethyl Cellulose
The quality of carboxymethyl cellulose CMC mainly depends on the solution of the product. If the product solution is clear, there are less gel particles, less free fibers, and less black spots of impurities. Basically, it can be determined that the quality of carboxymethyl cellulose is very good....Read more
