Hypromellose – Wikipedia

Hypromellose (), short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used as eye drops, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products.. As a food additive, hypromellose is an emulsifier, thickening and suspending agent, and an alternative to animal gelatin.E number: E464 (thickeners, …)

Hydroxypropyl cellulose – Wikipedia

Chemistry. HPC is an ether of cellulose in which some of the hydroxyl groups in the repeating glucose units have been hydroxypropylated forming -OCH 2 CH(OH)CH 3 groups using propylene oxide.The average number of substituted hydroxyl groups per glucose unit is referred to as the degree of substitution (DS). Complete substitution would provide a DS of 3. Because the hydroxypropyl group …E number: E463 (thickeners, …)

What is Hydroxypropyl Methyl Cellulose? (with pictures)

Hydroxypropyl Methyl Cellulose product is a non-ionic cellulose ether made through a series of chemical processes, with the natural polymer cellulose as the raw material. The product is a non-ionic cellulose ether in the shape of white powder, odorless and tasteless. In cold water, it swells into a clear or slightly turbid colloidal solution.

Jul 29, 2019· Hydroxypropyl methyl cellulose also carries code E464 in the European Union, making it a known and listed food additive. HPMC is a semi-synthetic compound that is non-toxic to humans. It must be treated carefully, however, as it does react strongly if …

The LD50 was reported to be greater than 5000 mg/kg/day. Dermal irritancy of hydroxypropyl cellulose has also been evaluated in human subjects (I4CTFA, 1962). Repeated application of a 10% aqueous solution of hydroxypropyl cellulose to the backs of 50 subjects for 24 hours did not elicit any signs of irritancy following a total of 10 exposures.
