  • The applicant did not provide new studies on the safety of HPMC, but made reference to previous assessment of celluloses (as a group) performed by other scientific bodies. Cellulose and cellulose derivatives were evaluated for their safety by JECFA (1990), which allocated a group ADI of ‘not specified’. The last comprehensive evaluation of cellulose and cellulose derivatives, including HPMC, for their use as food additives was done in 2017 by the ANS Panel (EFSA ANS Panel, 2018), which concluded that there was no need to set a numerical ADI. Although the data set available for the different celluloses is not complete and most of the studies were old and do not meet the current requirements of toxicological testing, the ANS Panel considered that the physico-chemical, structural, biological and kinetic similarities between the modified celluloses make it possible to apply a read-across approach among the different celluloses.

  • After spray-drying, the polymer particles are often coated with a protective layer to enhance their stability and redispersibility
  • Spray drying, for instance, is a popular method for producing redispersible powders because it allows for precise control over particle size and morphologyredispersible powder. The process involves spraying a liquid feedstock into a hot gas stream, which evaporates the solvent and leaves behind small, spherical particles. Coagulation, on the other hand, involves the aggregation of smaller particles into larger, more stable particles. This method is often used when a specific particle size distribution or shape is required. Fluidized bed granulation, finally, is a technique that combines drying and granulation in a single step. It is particularly useful for producing redispersible powders with good flow properties and high compactibility.
