HPMC - Everything you need to know

Skin care formula:

The applicant claims that the feed additive HPMC is specified to be manufactured to meet the specifications set for its use as a food additive. The main specifications as food and feed additive are: methoxyl groups ≥ 19 and ≤ 30%, hydroxypropoxyl groups ≥ 3 and ≤ 12%, loss on drying < 10%, sulfated ash < 1.5% (for products with viscosities of 50 mPa.s or above) or < 3% (for products with viscosities below 50 mPa.s). Five batches of the additive were analysed for some of the above specifications, resulting in: methoxyl groups (four batches) 23.5–29.2%, hydroxypropoxyl groups (four batches) 5.2–8.4%, loss on drying (one batch) 1.2% and sulfated ash (one batch) 0.6%. Only statements, without figures, of compliance with the specifications for some impurities (heavy metals, arsenic, solvents, microbial purity) were provided. Information on other impurities ((pesticides, dioxins, dioxin-like and non-dioxin-like polychlorinated biphenyls, mycotoxins, botanical impurities) was not provided.

Pharmaceuticals:

No data are available concerning the ADME of modified celluloses in the target animal species. However, the absence of significant metabolism in the rat and the human indicates that, despite an increase of water solubility, the etherification of cellulose would strongly limit the action of microbial cellulases. Consequently, the FEEDAP Panel considers that the lack of digestibility of these compounds in monogastric mammals, poultry and fish is likely to occur. In ruminants and hindgut animals (rabbit and horse), it cannot be excluded that the rich and complex microbiota would allow a limited enzymatic attack of these structures.
