Molecular weight: 59.0871
category
Food additives: thickeners and gelling agents
Appearance: A propylene glycol ether of methylcellulose, in which both hydroxypropyl and methyl groups are bound by ether bonds to the anhydrous glucose ring of cellulose. Different types of products, the proportion of methoxy and hydroxypropyl content is different. White to off-white fibrous powder or particles. Soluble in water and some organic solvents. Insoluble in ethanol, the aqueous solution has surface activity, forms a film after drying, and undergoes a reversible transformation from sol to gel after heating and cooling.
