Hydroxypropyl Methylcellulose CAS#9004-65-3
High purity and consistent quality – Hydroxypropyl methylcellulose is a white or off-white powder that is odorless and tasteless, with uniform particle size, ensuring reliable performance in various applications.
Excellent handling properties – The powder exhibits good fluidity and contains no mechanical impurities, making it easy to process, measure, and mix without clogging or contamination.
Rapid solubility in cold water – It dissolves quickly when stirred in cold water at 20–30℃, allowing for efficient preparation and saving time in production or formulation processes.
Forms a clear, uniform, and viscous solution – Upon dissolution, it creates a transparent and consistent viscous solution, ensuring high performance and stability in end-use applications.
Hydroxypropyl methylcellulose appears as a white to off-white powder that is both odorless and tasteless, featuring uniform particle size, excellent flowability, and free from mechanical impurities. Its main advantage is its rapid solubility in cold water while remaining insoluble in hot water — it quickly dissolves when stirred in cold water at 20–30℃, producing a clear, consistent, and viscous solution.

Product Usage
Hydroxypropyl methylcellulose (HPMC) finds extensive applications across multiple industries. In construction, it is used as an additive to improve material performance. In the pharmaceutical field, it serves various formulation purposes. Within the food industry, HPMC functions as a water-retaining agent in baking, a stabilizer for frozen products, and a thickener for beverages. In the daily chemical sector, it is employed as a thickener in cosmetics and as an anti-redeposition agent in detergents. Additionally, HPMC is applied in papermaking for sizing, in textile processing for fabric sizing, and in the bonding of ceramic materials.
