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).
Hypromellose , short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used in eye drops, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products.

Vegetable capsules, introduced in 1989, [5] are made from cellulose, a structural component in plants. The main ingredient of vegetarian capsules is hydroxypropyl methyl cellulose. In the 21st century, gelatin capsules are more broadly used than vegetarian capsules because the cost of production is lower. [citation needed]

E464 is hydroxypropyl methylcellulose [6] and more soluble in water. [7] Methyl cellulose, as a gel, has the unique property of setting when hot and melting when cold. [8] In some meat analogues that are intended to replicate the texture of meat, methyl cellulose is used as an ingredient, typically in concentrations less than 2%. [9] [10]
