Hydroxypropyl Methyl Cellulose (HPMC)– CAS 9004-65-3

Item Introduction

Hydroxypropyl methyl cellulose (HPMC) is a semi-synthetic, water-soluble polymer made from cellulose. It appears as a white to off-white powder. HPMC dissolves conveniently in cool water however does not liquify in warm water or most organic solvents. This product is extensively made use of across numerous sectors due to its stability, non-toxicity, and outstanding thickening properties.

Secret Includes

HPMC works well as a thickener, binder, film former, and water-retention representative. It remains steady over a wide pH range (typically 3– 11). The material does not sustain microbial development and stays clear in remedy. Its viscosity can be adjusted based upon molecular weight, which enables customization for different applications. HPMC also reveals great compatibility with lots of salts and other water-soluble polymers.

Common Applications

In building, HPMC improves workability and water retention in cement-based products like ceramic tile adhesives and renders. In pharmaceuticals, it functions as a binder in tablets and as a controlled-release matrix. The food industry makes use of HPMC as an emulsifier, stabilizer, or thickener under the E number E464. It is likewise found in personal treatment items such as hair shampoos, creams, and tooth pastes for texture and consistency. Repaint and finishing producers include HPMC to prevent sagging and improve application level of smoothness.

Applications of HPMC (Hydroxypropyl Methyl Cellulose)– CAS 9004-65-3

Building And Construction and Structure Products

HPMC is commonly made use of in building and construction products like tile adhesives, self-leveling compounds, and renders. It helps control water retention so cement can moisten properly. This improves workability and avoids cracks. The material also enhances attachment and makes mixing less complicated on site.

Drugs

In the drug sector, HPMC function as a binder, finishing representative, or controlled-release matrix. It is secure for human usage and liquifies slowly in the digestive system system. That allows medications to launch their energetic ingredients gradually. You will certainly find it in tablets, capsules, and eye drops.

Food Industry

HPMC serves as a thickener, emulsifier, or stabilizer in numerous processed foods. It keeps ingredients blended uniformly and provides items a smooth appearance. Typical usages include sauces, milk alternatives, and gluten-free baked items. It brings the food-grade label and meets international security standards.

Paints and Coatings

Paint makers add HPMC to water-based paints to improve consistency and avoid drooping. It assists pigments stay suspended and makes application smoother. The outcome is better coverage and fewer brush marks. It likewise minimizes splatter throughout splashing.

Cosmetics and Personal Care

In lotions, shampoos, and creams, HPMC jobs as a film-former and thickness modifier. It offers items an abundant feel without greasiness. It additionally helps energetic ingredients stick to skin or hair longer. The substance is gentle and compatible with a lot of aesthetic solutions.

Agriculture

Farmers usage HPMC in seed finishings and pesticide solutions. It secures seeds throughout growing and helps chemicals stay with plant surface areas. This boosts performance and minimizes waste. The product breaks down normally in dirt in time.

5 FAQs of HPMC / Hydroxypropyl methyl cellulose CAS 9004-65-3

Frequently Asked Questions About HPMC (Hydroxypropyl Methyl Cellulose)

What is HPMC?

HPMC stands for Hydroxypropyl Methyl Cellulose. It is a white or off-white powder made from natural cellulose. People use it in many industries because it dissolves in water and forms a clear, thick solution. It is safe and widely accepted for use in food, medicine, and building materials.

Is HPMC safe to use?

Yes, HPMC is safe. Regulatory bodies like the FDA and EFSA have approved it for use in food and pharmaceuticals. It does not get absorbed by the body when taken orally. Instead, it passes through the digestive system unchanged. In construction, it poses no health risk when handled properly.

What are the main uses of HPMC?

HPMC works as a thickener, binder, and water-retaining agent. In food, it improves texture and stability. In medicines, it helps control how fast a drug dissolves. In construction, it keeps cement and tile adhesives workable longer by holding water. It also appears in cosmetics and paints for similar reasons.

How should HPMC be stored?

Store HPMC in a cool, dry place. Keep it away from moisture and direct sunlight. Use sealed containers to prevent clumping. If stored correctly, it stays stable for up to two years. Always check the label for specific storage instructions from the manufacturer.

Can HPMC be mixed with other chemicals?

HPMC mixes well with most common ingredients. However, strong acids, bases, or high salt levels may reduce its performance. Always test small batches first when combining it with new substances. This helps avoid unexpected reactions or loss of viscosity.
