What is instant hydroxypropyl methylcellulose

Instant Hydroxypropyl Methylcellulose (Instant Hydroxypropyl Methylcellulose, referred to as S in China) is a special form of hydroxypropyl methylcellulose. Compared with ordinary HPMC, instant HPMC dissolves faster in water and can be quickly dispersed in water. But it didn’t dissolve.

The cold water instant type of HPMC is surface-treated with glyoxal, and it disperses quickly in cold water, but it does not really dissolve. Only when the viscosity increases, it dissolves. Ordinary HPMC has not been treated with glyoxal. If the amount of glyoxal is large, the dispersion will be fast, but the viscosity will increase slowly, and if the amount is small, the opposite will be true.

Instant hydroxypropylmethylcellulose (HPMC) is a modified cellulose polymer used primarily in the detergent and personal care industries. It is a white or off-white powder that dissolves in cold water to form a clear, viscous solution.

The “instant” in instant HPMC means that it dissolves quickly and easily in cold water without high shear mixing or heating. This makes it a popular choice for detergents and personal care products.
