Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on hydroxypropyl methyl cellulose as a feed additive for all animal species. Hydroxypropyl methyl cellulose is intended for use as a technological additive (functional group: stabiliser) in premixtures and feedingstuffs for all animal species with no minimum and maximum content. A proper identification and characterisation of hydroxypropyl methyl cellulose as required for a feed additive is not available and the occurrence of potential toxic impurities cannot be assessed. The following conclusions apply only to hydroxypropyl methyl cellulose meeting the food additive specifications. The FEEDAP Panel concluded that hydroxypropyl methyl cellulose is considered safe for all animal species. The use of hydroxypropyl methyl cellulose in animal nutrition is of no concern for consumer safety. In the absence of data, the FEEDAP Panel was not in the position to conclude on the safety of hydroxypropyl methyl cellulose for the user. The use of hydroxypropyl methyl cellulose as a feed additive is considered safe for the environment. The additive is considered to be efficacious in feedingstuffs for all animal species.

In general, HPMC is more soluble in hot water than in cold water. This is because the increased temperature causes the polymer chains to become more flexible, allowing them to entangle less and dissolve more easily. However, even at room temperature, HPMC can still dissolve in water to some extent, although the dissolution rate may be slower.

Moreover, HPMC enhances the cleaning performance of detergents by improving their wetting ability. It facilitates the penetration of water and cleaning agents into fabrics, thereby increasing the removal of dirt and stains It facilitates the penetration of water and cleaning agents into fabrics, thereby increasing the removal of dirt and stains
