Detergents
Hydroxypropyl Methylcellulose (HPMC)
Formula:
C₅₆H₁₀₈O₃₀
GOST/CAS:
CAS 9004-65-3
Hydroxypropyl Methylcellulose (a highly effective non-ionic water-soluble polymer derived from cellulose) is a specialized component acting as a key agent for thickening, stabilizing, moisture retention, and rheology control in liquid and gel systems. The product is a white to off-white powder or granulates, readily soluble in cold water (forming a transparent, viscous colloidal solution). Due to its high compatibility with surfactants and its ability to generate stable, dense foam, HPMC is indispensable in the formulation of household detergents, cosmetics, liquid cleaning agents, and construction chemicals.
Applications
Household Detergents & Cosmetics: Used as a primary thickener and viscosity modifier in liquid hand soaps, shower gels, shampoos, dishwashing liquids, and laundry detergents. It enhances foam stability and prevents phase separation of ingredients.
Auto Care & Car Wash Chemicals: Incorporated into touchless car wash shampoos, glass cleaners, and polishes. It ensures optimal cling of the formulation to vertical surfaces (rich, "clinging" foam effect) for deep cleaning action.
Industrial Cleaners: Added to concentrated degreasers, heavy-duty cleaning gels, and soot removers. It improves wetting ability and extends the contact time of active agents with the contaminants.
Construction Chemicals & Adhesives: Applied as a water-retention additive and thickener in tile adhesives, plasters, and wall putties. It prolongs open time and improves sag resistance.
Key Advantages
Excellent Thickening & Rheology Control: Effectively boosts viscosity even at low dosages, ensuring a smooth, controlled pour for liquid products and providing a premium appearance to the final formulation.
Foam & Emulsion Stabilization: Exhibits surface activity, thereby stabilizing rich foam in detergents and preventing syneresis (water separation) during long-term storage.
High Compatibility & Salt Tolerance: The non-ionic nature of the polymer guarantees flawless compatibility with anionic, cationic, and non-ionic surfactants, maintaining stability across a wide pH range and in the presence of electrolytes.
Safety & Biodegradability: Environmental-friendly, non-toxic, hypoallergenic, and biodegradable, posing no negative impact on the ecosystem upon disposal when handled correctly.
