Specification of HPMC/Hydroxypropyl methyl cellulose hpmc e5 e15 chemical, cas 9004-65-3

Hydroxypropyl Methyl Cellulose (HPMC)– Technical Grade E5 & E15

Item Overview

Hydroxypropyl methyl cellulose (HPMC), CAS No. 9004-65-3, is a semi-synthetic, water-soluble polymer made from cellulose. It is commonly used in construction, pharmaceuticals, food, and individual care products. The E5 and E15 qualities are standard technical kinds understood for their reputable efficiency and constant high quality.

Secret Qualities

HPMC E5 and E15 look like white to beige powders. They liquify easily in chilly water yet not in hot water. As soon as mixed with cold water, they form clear, thick solutions. These qualities provide good film-forming capacity, water retention, and thickening power. They continue to be steady across a broad pH range (generally 3– 11) and do not support microbial development.

Typical Applications

In the building sector, HPMC E5 and E15 are included in cement-based items like floor tile adhesives, renders, and self-leveling compounds. They improve workability, extend open time, and lower water loss during healing. In drugs, these qualities serve as binders, finishings, or controlled-release agents in tablet computers. Food manufacturers utilize them as stabilizers or thickeners. They also appear in cosmetics for appearance enhancement and dampness control.

Handling and Storage

Shop HPMC in a trendy, dry location far from straight sunlight and wetness. Maintain containers snugly closed when not in use. Stay clear of breathing dust during handling. Use typical safety equipment such as gloves and shatterproof glass. The shelf life is generally 24 months if saved effectively.

Applications of HPMC (Hydroxypropyl Methyl Cellulose)

Secret Utilizes Throughout Industries

HPMC, or hydroxypropyl methyl cellulose (CAS 9004-65-3), is a versatile, water-soluble polymer commonly made use of in many markets. It serves as a thickener, binder, film previous, and stabilizer. Its qualities– such as E5 and E15— are picked based on viscosity and efficiency needs.

In the building market, HPMC improves workability and water retention in cement-based products like floor tile adhesives, provides, and self-leveling substances. This helps guarantee solid bond and decreases splitting during drying.

In pharmaceuticals, HPMC E5 and E15 act as essential excipients. They are utilized in tablet coatings to manage medication release. They also work as binders in granulation and as thickness enhancers in eye decreases. Their safety and compatibility with energetic components make them excellent for dental and topical solutions.

The food market usages food-grade HPMC as an emulsifier, thickener, or foam stabilizer. It helps maintain structure and consistency in products like gelato, sauces, and gluten-free baked items. HPMC is authorized by significant food safety authorities worldwide.

In individual care and cosmetics, HPMC supplies smooth appearance and security. It is located in hair shampoos, lotions, and tooth pastes, where it aids suspend fragments and enhance spreadability.

HPMC additionally plays a role in farming. It is made use of in chemical solutions to enhance bond to plant surfaces and regulate the release of active components. This boosts effectiveness while decreasing waste.

Its capability to liquify in cool water, kind clear movies, and continue to be secure throughout a variety of pH levels makes HPMC a reputable choice for formulators. Whether in building products, medications, food, or cosmetics, HPMC delivers consistent performance with very little influence on final product high quality.
