Hydroxypropyl methyl cellulose (HPMC) is a cellulose derivative that was first developed and used in industrial and food applications starting in the 20th century. Its exact origin in terms of discovery and initial development is difficult to attribute to a single individual or organization, as research and development of cellulose derivatives has involved many scientists and companies at different times.

HPMC is produced through a chemical process known as etherification, in which natural cellulose is treated with hydroxypropyl chloride and sodium methoxide. This process alters the chemical structure of cellulose, making it water-soluble and giving it desired properties as a thickener, stabilizer and film-forming agent.

Production and Use over Time:

The use of HPMC in industrial and food applications has grown significantly since the mid-20th century, when researchers began to more fully explore the potential uses of cellulose derivatives. Its ability to act as a thickener, emulsifier and stabilizer has increased its adoption in a variety of industries, including pharmaceuticals, cosmetics and food.

• Answer: HPMC can be divided into instant type and hot dissolve type, instant products, in cold water quickly dispersed, disappeared in water, at this time the liquid has no viscosity, because HPMC is just dispersed in water, no real dissolution. After about 2 minutes, the viscosity of the liquid gradually increases, forming a transparent, sticky gel. Hot soluble products, in cold water, can quickly disperse in hot water, disappear in hot water, when the temperature drops to a certain temperature, viscosity slowly appear, until the formation of transparent viscous colloid. Hot soluble type can only be used in putty powder and mortar, in liquid glue and paint, there will be clumping phenomenon, can not be used. Instant type, a wide range of applications, in putty powder and mortar, as well as liquid glue and paint, can be used, there is no taboo。
