Personal Care Products

Used as adhesive and sizing agent in fabric printing and dyeing slurries and latex paints; used as thickener for sizing materials on the back of carpets. Used as molding agent and binder in glass fiber; used as modifier and binder in leather pulp. Providing these coatings or adhesives with a wider viscosity range allows the coating to settle more evenly and quickly, and improves print clarity.

HPMC grades are categorized based on their viscosity, typically measured in centipoise (cP) at a specific concentration and temperature. Common grades include

Hydroxypropyl Methyl Cellulose (HPMC) Suppliers in China

HPMC is widely used in the food industry as a food additive and thickening agent. It is designated as E464 in the European Union and is recognized for its ability to enhance texture and moisture retention in food products. HPMC is often found in gluten-free baked goods, sauces, and dressings, where it serves to improve consistency and mouthfeel. Its emulsifying properties help stabilize oil and water mixtures, ensuring uniformity in products.
