Premium HPMC Cellulose Ether Factory Leading China Suppliers of Hydroxypropyl Methylcellulose
Hydroxypropyl Methylcellulose (HPMC) is a high-performance non-ionic cellulose ether derived from natural polymer materials. Engineered for versatility, our HPMC is categorized into two primary dissolving types—Instant Dissolving and Hot Dissolving—to meet the stringent requirements of diverse industrial applications ranging from personal care detergents to heavy-duty construction materials.
Whether utilized as a thickener, water retention agent, or emulsifier, our HPMC ensures superior stability and workability. By optimizing the molecular structure, we provide a product that prevents cracking in mortars, enhances the texture of cosmetic gels, and ensures consistent viscosity, making it an essential additive for manufacturers seeking professional-grade chemical solutions.

Frequently Asked Questions
Instant dissolving HPMC is soluble at room temperature, making it ideal for cosmetics and detergents. Hot dissolving HPMC requires water above 60°C and is primarily used in construction and ceramics for better water retention.
By burning a sample, you can observe the ash residue. A high-quality HPMC should have an ash ratio of less than 5%. The less residue left after burning, the purer the product.
Higher density generally correlates with higher purity. You can test this by weighing the same volume of powder in a measuring cup; the heavier the sample, the purer the material.
Hot dissolving HPMC is recommended for these applications. It acts as a powerful water retention agent, prevents drooping, and ensures the mortar is anti-cracking.
Yes, the instant dissolving type is widely used in the detergent and cosmetic industries for shampoos, liquid soaps, and toothpaste due to its high permeability and thickening properties.
Yes, we provide free samples from different batches to help you verify quality stability. The buyer is only responsible for the air shipping costs.
