Benecel™ methylcellulose and hydroxypropyl methylcellulose INCI Name: Methylcellulose and Hydroxypropyl Methylcellulose

Benecel methylcellulose (MC) is made by reacting methyl chloride with alkali-cellulose under rigidly controlled conditions. The resultant nonionic polymer is purified, dried and ground to a fine white powder, which is readily soluble in cold water. It is also possible to graft a hydroxypropyl group onto the MC polymer backbone, creating Benecel hydroxypropyl methylcellulose (HPMC).

Also a nonionic, cold water-soluble polymer, HPMC is a good film-former and varies somewhat in physical and chemical properties from MC. Benecel MC and HPMC are quite hydrophilic and readily soluble in cold water.

As the water temperature is raised, polymers pass through a thermal gelation phase, where solution viscosity rises rapidly, followed by flocculation and precipitation of the polymer out of solution. This precipitation is thermally reversible and occurs at different temperatures, depending on type and degree of substitution. Benecel MC and HPMC are compatible with most personal care surfactant systems.
