Common Uses

This HPMC grade works well as a thickener, binder, film-former, and water-retention agent. In construction, it improves workability and adhesion in tile adhesives, plasters, and self-leveling compounds. In pharmaceuticals, it serves as a controlled-release matrix in tablets and as an ingredient in eye drops. The food industry uses it as a stabilizer and emulsifier. It also appears in cosmetics for texture and moisture control.

Storage and Handling

Store HPMC in a cool, dry place away from direct sunlight and moisture. Keep the container tightly closed when not in use. Avoid contact with strong acids or bases. Use standard safety practices when handling—wear gloves and eye protection if needed. The shelf life is typically 24 months when stored properly.

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

Building and Construction

HPMC 9004-65-3 is widely used in cement-based products like tile adhesives, self-leveling compounds, and renders. It helps control water retention so cement hydrates properly. This leads to stronger bonds and fewer cracks. The polymer also improves workability, making the mix easier to spread and shape.

Pharmaceuticals

In medicine, HPMC acts as a binder, thickener, or film-forming agent. It is common in tablets, capsules, and eye drops. The material is safe for human use and dissolves slowly in the body. This allows drugs to release at a steady rate. Many over-the-counter and prescription medicines rely on HPMC for consistent performance.

Food Industry

HPMC serves as a stabilizer and emulsifier in various foods. You can find it in low-fat spreads, baked goods, and gluten-free products. It helps maintain texture and moisture without altering taste. Because it is plant-based and non-toxic, it meets strict food safety standards worldwide.

Paints and Coatings

Paint makers add HPMC to water-based paints to prevent sagging and improve coverage. It keeps pigments evenly mixed and stops them from settling. The result is a smooth finish with better adhesion to walls and surfaces. HPMC also boosts open time, giving painters more room to work before the paint dries.

Cosmetics and Personal Care

In lotions, shampoos, and creams, HPMC creates a rich, creamy feel. It holds water well, which helps keep skin and hair hydrated. The polymer is gentle on the skin and does not cause irritation. Its natural origin makes it a popular choice in clean-label beauty products.

5 FAQs of Hydroxypropyl Methyl Cellulose HPMC 9004 65 3 Natural Polymers

Frequently Asked Questions About Hydroxypropyl Methyl Cellulose (HPMC) 9004-65-3

What is HPMC 9004-65-3?

HPMC 9004-65-3 is a natural polymer made from cellulose. It comes from plant fibers, usually wood or cotton. This substance is modified to dissolve in water and form clear, thick solutions. People use it in many industries because it works well and is safe.

Where is HPMC used?

HPMC is common in construction, food, pharmaceuticals, and cosmetics. In building materials, it helps keep water in mortar and tile adhesives so they set evenly. In pills, it controls how fast medicine is released. In food, it acts as a thickener or stabilizer. You’ll also find it in lotions and creams to improve texture.

Is HPMC safe?

Yes. HPMC has been tested and approved for use in food and medicines by major health agencies like the FDA and EFSA. It does not get absorbed by the body. Instead, it passes through the digestive system unchanged. That makes it very safe for most people.

How does HPMC work in construction products?

In cement-based mixes, HPMC holds water so the mixture stays wet longer. This gives workers more time to work with the material. It also stops the mix from separating and helps it stick better to surfaces. The result is a stronger, smoother finish.

Can HPMC be mixed with other ingredients?

Yes. HPMC mixes well with many common ingredients. It works with salts, acids, and other thickeners. Still, you should test small batches first. Some combinations might affect how thick or stable the final product becomes. Always follow recommended usage levels for best results.
