产品介绍

Hydroxypropyl methylcellulose (HPMC), also known as hypromellose, is a semisynthetic, inert, viscoelastic polymer. It is a derivative of natural cellulose, typically sourced from plant materials like wood pulp or cotton fibers. HPMC is produced by chemically treating cellulose with methyl chloride and propylene oxide.

用途

Common Uses and Applications:

HPMC is highly versatile and used across a wide range of industries due to its multi-functional properties:

• 制药行业：

  • 赋形剂： Used in tablets and capsules as a binder, disintegrant, film-former, and controlled-release agent to delay drug release.
  • Capsule Shells: A popular vegetarian/vegan alternative to gelatin capsules.
  • Ophthalmic Applications: Viscosity enhancer and lubricant in eye drops for dry eyes.
  • Bioavailability Enhancement: Can improve the solubility and absorption of poorly soluble drugs.

• 食品工业：

  • 增稠剂： Used in sauces, soups, dressings, and other food products to achieve desired viscosity and texture.
  • Stabilizer: Helps maintain consistency and uniformity in food products.
  • 乳化剂： Prevents separation of oil and water in products like salad dressings.
  • Gluten-Free Baking: Provides structure and texture in gluten-free baked goods, acting as a gluten substitute.
  • Fat Replacer: Can act as a lubricant to maintain a creamy mouthfeel in low-fat products.

• Construction Industry:

  • Mortars and Plasters: Improves workability, water retention, sag resistance, and adhesion in cement-based mortars, gypsum-based plasters, tile adhesives, and self-leveling compounds.
  • Rheology Modifier: Adjusts the flow properties of building materials.

• Personal Care and Cosmetics:

  • 增稠剂： Adds viscosity to lotions, creams, shampoos, and gels.
  • Film-former: Provides a smooth film on skin or hair, enhancing the feel and appearance of products.
  • Stabilizer: Ensures uniformity and stability of cosmetic formulations.

• Paints and Coatings:

  • Thickening Agent: Adjusts the viscosity of paints for better application and finish.
  • Stabilizer: Prevents pigment settling and improves storage stability.

• Other Applications:

  • Textile Industry: Used as a sizing agent.
  • Detergents and Cleaners: Enhances viscosity.
  • Agriculture: Acts as a binder and stabilizer in pesticide and herbicide formulations.
