Hydroxypropyl Methylcellulose for daily care

Hydroxypropyl Methyl Cellulose, abbreviated as HPMC, is divided into cold-water instant type and slow-dissolving type, and the difference between them is quite big. Let's talk about the difference between them from the aspects of technology, application field and their respective functions: the cold-water instant hydroxypropyl methyl cellulose is mainly treated with glyoxal, and if it is put in cold water, it will dissolve quickly, and the viscosity will come up, and the aqueous solution will become clear and transparent, so it can be regarded as real dissolution. As for the slow-dissolving hydroxypropyl methylcellulose, it is also called hot-dissolving type, mainly because it has not been treated with glyoxal. When the amount of glyoxal is large, it will disperse faster, but the viscosity will come up slowly. If the amount of HPMC is small, it will disperse slowly, but the viscosity will come up quickly.
