Hydroxy Propyl Methyl Cellulose (HPMC)

Hydroxy Propyl Methyl Cellulose (HPMC) is a versatile, non-ionic cellulose ether derived from natural sources like wood or cotton fibers. HPMC is widely used as a thickening, emulsifying, film-forming, and stabilizing agent across multiple industries, including pharmaceuticals, cosmetics, food, and construction. It dissolves easily in water, forming transparent or milky solutions, and is valued for its excellent water retention properties and high pH stability.

Applications

• Pharmaceuticals: Used as a binder in tablets, a film-forming agent for coatings, and a controlled-release agent in drug formulations.
• Cosmetics: Incorporated into creams, lotions, and gels for thickening, emulsifying, and improving the texture of formulations.
• Food industry: Acts as a stabilizer, emulsifier, and thickener in products like sauces, creams, and baked goods (with regulatory approval).
• Construction: Used as a water-retaining agent in cement, plaster, and mortar formulations to improve workability and prevent cracking.
• Paints and coatings: Provides film-forming and thickening properties in water-based paints, helping to enhance texture and stability.
• Detergents: Acts as a thickening and stabilizing agent in liquid detergents and household cleaning products.

Handling and Storage

• Handling:
  • Use appropriate protective equipment, such as gloves and a dust mask, to avoid inhalation and skin contact.
  • Work in a well-ventilated area to minimize exposure to dust.
  • Avoid contact with strong oxidizing agents.
• Storage:
  • Store in a cool, dry place, away from direct sunlight and moisture.
  • Keep the container tightly closed to prevent contamination and moisture absorption.
  • Ideal storage temperature: Between 5°C and 30°C.
  • Protect from high humidity, as HPMC is hygroscopic and may clump if exposed to moisture.

Safety

• HPMC is generally regarded as safe for use in various applications, including pharmaceuticals, cosmetics, and food products.
• Avoid ingestion or inhalation of the powder.
• In case of eye contact, rinse immediately with water.
• If skin irritation occurs, discontinue use and seek medical advice.
• Keep out of reach of children.
