Hydroxyethyl Cellulose (HEC)– Product Requirements

Fundamental Information

Chemical Call: Hydroxyethyl Cellulose
CAS Number: 9004-62-0
Molecular Formula: C₂H₆O₂· C₆H₇( OH)₃O₂ (repeating unit).
Ordinary Molecular Weight: Varies by grade (usually 90,000– 1,300,000 g/mol).

Physical Qualities

HEC appears as a white to off-white, free-flowing powder. It is odorless and non-ionic. The material dissolves quickly in cool water to create clear, viscous options. It does not dissolve in a lot of organic solvents like ethanol, acetone, or chloroform. HEC options remain stable across a large pH variety (typically 3– 11). The viscosity of the solution relies on focus, molecular weight, and temperature level.

Trick Includes

HEC supplies outstanding thickening, suspending, and water-retention residential properties. It functions well in both acidic and alkaline systems. The product reveals excellent compatibility with salts, surfactants, and various other water-soluble polymers. It additionally supplies film-forming ability and boosts attachment in several formulas. HEC is non-toxic and biodegradable under ideal conditions.

Common Applications

This quality of HEC is widely made use of in building materials such as floor tile adhesives, concrete renders, and self-leveling compounds. It is likewise common in paints and layers to control flow and stop pigment settling. Personal care products like shampoos, lotions, and tooth pastes use HEC for texture and security. Various other uses include drugs (as a binder or controlled-release agent), agricultural chemicals, and oilfield exploration liquids.

Storage space and Handling

Store HEC in a trendy, completely dry location away from dampness. Keep containers firmly shut when not being used. Prevent direct exposure to high humidity, which might trigger clumping. Use conventional industrial health methods throughout handling. Wear gloves and eye defense if long term contact is anticipated.

Applications of HEMC, HPMC, and Hydroxyethyl Cellulose (HEC)– CAS 9004-62-0

Building And Construction and Building Materials

HEC, HPMC, and HEMC are commonly used in building and construction products. They boost water retention in cement-based products like floor tile adhesives, makes, and self-leveling substances. This aids the cement moisturize effectively, which results in more powerful bonds and less cracks. These cellulose ethers also make mixes simpler to work with by giving them a smooth, regular appearance.

Paints and Coatings

In water-based paints, hydroxyethyl cellulose (HEC) serves as a thickener. It manages exactly how the paint flows and spreads on surface areas. This protects against sagging on wall surfaces and makes certain also insurance coverage. HEC likewise maintains pigments and other solids equally combined, so the paint remains secure with time and does not different in the can.

Personal Treatment and Cosmetics

These cellulose derivatives prevail in shampoos, creams, and creams. They offer items an abundant, luscious feeling without being oily. HEC and HPMC aid put on hold fragments, support solutions, and control thickness. They are gentle on skin and compatible with numerous other components utilized in personal treatment solutions.

Drugs

In medicine, HPMC and HEC function as binders, film formers, and controlled-release agents. They are utilized in tablet computers, eye drops, and lotions. Their capacity to swell or liquify at details prices makes them suitable for timed medication distribution. These products are safe and approved for use in numerous regulated health and wellness products.

Other Industrial Uses

Beyond these fields, cellulose ethers discover functions in cleaning agents, agrochemicals, and ceramics. In cleaning products, they aid suspend dirt and improve cling to upright surface areas. In chemicals, they guarantee also spreading and sticking to plant leaves. In ceramic lusters, they help in application and decrease splitting throughout drying out.

5 FAQs of Hemc Hpmc Hydroxyethyl Cellulose Hec 9004-62-0

Frequently Asked Questions About HEMC/HPMC (Hydroxyethyl Methyl Cellulose)

What is HEMC/HPMC?

HEMC or HPMC stands for Hydroxyethyl Methyl Cellulose. It is a water-soluble polymer made from natural cellulose. People use it in many industries like construction, pharmaceuticals, and food. Its chemical ID is CAS 9004-62-0.

Why is HPMC used in construction materials?

HPMC helps control water retention in cement-based products. This means tiles, plasters, and mortars stay workable longer. It also improves adhesion and reduces cracking. Builders rely on it to get smooth, strong results.

Is HPMC safe for use in food or medicine?

Yes. When made to meet food-grade or pharma-grade standards, HPMC is safe. It acts as a thickener, stabilizer, or binder. Regulatory bodies like the FDA approve it for these uses. Always check the product specification to confirm its grade.

How does HPMC dissolve in water?

HPMC dissolves easily in cold water but not in hot water above a certain temperature. Mix it slowly to avoid lumps. Stirring helps it form a clear, viscous solution. The final viscosity depends on the grade and concentration used.

What makes HEMC different from regular HEC or HPMC?

HEMC is a hybrid that includes both hydroxyethyl and methyl groups. This gives it better stability over a wide pH range and improved performance in high-salt environments. Compared to pure HEC or HPMC, HEMC often offers more balanced properties for demanding applications.
