A proper identification and characterisation of HPMC as required for a feed additive is not available and the occurrence of potential toxic impurities cannot be assessed.
11. What is related to the gel temperature of hydroxypropyl methyl cellulose?
But, there are some potential disadvantages that are not immediately obvious. HPMC is listed as a food ingredient — E464 — which means that recommended daily maximum quantities must be defined. HPMC undergoes a rigorous manufacturing process involving the synthetic — and not natural — alteration of cellulose. During production, various highly reactive, harmful or toxic substances are used that must be removed and disposed after production, including propylene oxide (which is considered to be carcinogenic) and chloromethane.


High viscosity (150,000-200,000) is mainly used for polystyrene particle insulation mortar powder and vitrified microbead insulation mortar. The higher viscosity helps prevent mortar from dusting and sagging, improving the construction process.
