Hydroxypropyl Methyl Cellulose - HPMC Powder
Hydroxypropyl Methyl Cellulose (HPMC) is made from pulverized refined cotton, alkalized with sodium hydroxide (liquid caustic soda) solution, etherified with methyl chloride and propylene oxide, then neutralized, obtained after filtering, drying, crushing and sieving.
Product Description
Functionality: HPMC is a multifunctional compound used as a lubricant, foam enhancer, stabilizer, thickener, emulsion stabilizer, and film-forming agent in hair and skin care products.
Surfactant Compatibility: Particularly useful in surfactant systems, enhancing foam formation and durability.
Resistance: Exhibits high tolerance to salt and alcohol.
General Properties of HPMC:
Polymer: HPMC is a polymer derived from chemically modified natural cellulose fibers, presenting as a slightly off-white to transparent synthetic polymer.
Solubility: It is a powder that is soluble in water and some organic solvents.
Applications: Widely used as a thickener, adhesive, emulsifier, stabilizer, and suspending agent in industries such as rubber and textiles.

Chemical Advantages of HPMC:
Versatility: Acts as a superior thickener at low concentrations, producing transparent solutions. At high concentrations, it has low viscosity.
Compatibility: Compatible with various substances and non-irritating, non-toxic, and environmentally friendly.
Application Benefits:
Thickening Agent: Used in adhesives, coatings, and paints.
Water Retention: Effective in maintaining water content, beneficial in areas such as cement, gypsum, and mortar.
Film Formation: Dissolves in water to form a thin, semi-transparent, flexible film. Valuable in the production of capsules, tablets, cosmetics, and personal care products.
Emulsifier: Improves the texture and viscosity of emulsion-dependent products like creams and lotions.
Binder: Enhances strength and stability by bonding particles or components in formulations.
Suspending Agent: Maintains particle suspension in liquids, applicable in the production of paints, inks, and coatings.
Applications in Various Industries:
Construction Industry:
Basic additive for cement-based materials to improve performance, including workability, water retention, adhesion, and durability.
Used in tile adhesives, self-leveling compounds, plastering, and rendering.
Pharmaceutical Industry:
Coating agent for tablets and capsules.
Binding agent for wet granulation.
Component in eye solutions and oral formulations for controlled release.
