Hydroxypropyl methylcellulose (HPMC)
Identification:
Chemical Name: Hydroxy Propyl Methyl Cellulose
Synonyms: Hypromellose; Methocel ;Walocel
CAS No.: 9004-65-3
Molecular Formula: C12H20O10
E-Code: E464
Properties:
HPMC is a solid, and is a slightly off-white to beige powder in appearance and may be formed into granules. The compound forms colloids when dissolved in water. This non-toxic ingredient is combustible and can react vigorously with oxidising agents
