Description:
Hydroxyethyl Methylcellulose is a white or off-white powder that is odorless and tasteless. It is produced by modifying cellulose with both hydroxyethyl and methyl groups. The degree of substitution (DS) of HEMC refers to the average number of hydroxyethyl and methyl groups per glucose unit in the cellulose chain. HEMC is available in different DS values, which influence its solubility and viscosity properties.
Specifications:
Application:
Hydroxyethyl Methylcellulose has a wide range of applications in various industries, including:
Construction Industry: HEMC is commonly used as a thickener, water retention agent, and rheology modifier in cement-based products such as tile adhesives, mortar, gypsum-based plasters, and self-leveling compounds. It improves workability, adhesion, and sag resistance of these formulations.
Paints and Coatings: HEMC is employed as a thickener, binder, and stabilizer in water-based paints, coatings, and adhesives. It enhances viscosity control, film formation, and reduces spattering during application.
Personal Care Products: HEMC is utilized in cosmetics and personal care products, including shampoos, body washes, and creams. It acts as a thickener, emulsion stabilizer, and moisture retention agent, improving the texture, stability, and sensory attributes of these formulations.
Pharmaceutical Industry: HEMC is used as a binder, film-former, and controlled-release agent in pharmaceutical tablets and capsules. It provides tablet integrity, controlled drug release, and improved patient acceptability.
Features:
Water Solubility: HEMC readily dissolves in water, forming clear and viscous solutions. The solubility can vary depending on the degree of substitution and viscosity grade.
Thickening and Rheology Control: HEMC exhibits excellent thickening and rheology control properties. It can increase viscosity, improve sag resistance, and enhance the stability of formulations.
Pseudoplastic Behavior: HEMC solutions display shear-thinning behavior, where the viscosity decreases under shear stress, facilitating easy application and spreading.
Compatibility: HEMC is compatible with a wide range of other ingredients commonly used in formulations, including various salts, surfactants, and polymers.
pH Stability: HEMC remains stable over a wide pH range, making it suitable for use in acidic and alkaline formulations.
Film-Forming: HEMC can form flexible and transparent films, providing barrier properties and moisture retention.
