Wie gefährlich ist HPMC?

Hydroxypropyl Methylcellulose is non-ionic cellulose mixed ether made from refined cotton by alkaline treatment and then by a series of reactions with propylene epoxide and methyl chloride as etherifying agents. The degree of substitution is generally 1.2-2.0. Its properties are varied depending on the difference of the proportion of methoxy content and hydroxy-propyl content.
