Water Retention Agent HPMC/ Hydroxypropyl Methylcellulose CAS 9004-65-3 For Construction Industry

 

 

Description:
Hydroxypropyl Methylcellulose is a white or off-white powder that is odorless and tasteless. It is produced by modifying cellulose with both hydroxypropyl and methyl groups. The degree of substitution (DS) of HPMC refers to the average number of hydroxypropyl and methyl groups per glucose unit in the cellulose chain. HPMC is available in different DS values, which influence its solubility, gelation, and viscosity properties.

Specifications:

 

• Appearance: White or off-white powder
• Assay: ≥ 99%
• Moisture Content: ≤ 5%
• pH value: 5.0-8.0

Application:
Hydroxypropyl Methylcellulose has a wide range of applications in various industries, including:

1. Construction Industry: HPMC 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.

2. Pharmaceutical Industry: HPMC is widely utilized in pharmaceutical formulations as a binder, film-former, sustained-release agent, and viscosity enhancer. It is commonly used in tablet coatings, controlled-release matrices, ophthalmic solutions, and topical gels.

3. Personal Care Products: HPMC is used in cosmetics and personal care products, including shampoos, body washes, creams, and lotions. It acts as a thickener, emulsion stabilizer, and moisture retention agent, improving the texture, stability, and sensory attributes of these formulations.

4. Food Industry: HPMC finds application as a food additive, primarily as a thickener, stabilizer, and emulsifier. It is used in various food products such as sauces, dressings, bakery items, and beverages to enhance texture and provide stability.

Features:

• Water Solubility: HPMC 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: HPMC exhibits excellent thickening and rheology control properties. It can increase viscosity, improve sag resistance, and enhance the stability of formulations.

• Pseudoplastic Behavior: HPMC solutions display shear-thinning behavior, where the viscosity decreases under shear stress, facilitating easy application and spreading.

• Compatibility: HPMC is compatible with a wide range of other ingredients commonly used in formulations, including various salts, surfactants, and polymers.

• pH Stability: HPMC remains stable over a wide pH range, making it suitable for use in acidic and alkaline formulations.

• Film-Forming: HPMC can form flexible and transparent films, providing barrier properties and moisture retention.

 

Hydroxypropyl methyl cellulose(hpmc)/ hypromellose,

hypromellose (inn), short for hydroxypropyl methylcellulose (hpmc), is a semisynthetic, inert, viscoelastic polymer used as an ophthalmic lubricant, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products.as a food additive, hypromellose is an emulsifier,thickening and suspending agent, and an alternative to animal gelatin.its codex alimentarius code (e number) is e464.
