Hydroxypropyl Methyl Cellulose (HPMC)– Product Specifications

Chemical Identity

Hydroxypropyl Methyl Cellulose (HPMC) iku semi-sintetik, polimer larut banyu digawe saka selulosa. It appears as a white to beige powder. The material has no odor and is non-toxic. HPMC satisfies food, pharmaceutical, and industrial grade standards.

Panggenan Fisik

The powder flows easily and dissolves conveniently in cool water. It forms a clear to slightly over cast thick remedy. HPMC does not liquify in warm water above 70 ° C but will gel when heated up. As soon as cooled, it redissolves. Its thickness ranges from 5 mPa · s to over 100,000 mPa · s, gumantung ing kualitas.

Pureness and Structure

Regular HPMC consists of:
– Methoxy groups: 19%– 30%.
– Hydroxypropoxy groups: 4%– 32%.
– Isi udan: ≤ 5%.
– Konten web awu: ≤ 1.5%.
– pH (2% solusi): 4.0– 8.0.

Hefty metals and microbial limits comply with pertinent pharmacopeial demands (contone., USP/NF, EP, JP).

Functional Performance

HPMC dianggo uga minangka thickener, pengikat, movie previous, lan agen penylametan banyu. In construction products like floor tile adhesives and provides, it aids maintain water in the mix much longer, enhancing workability and attachment. Ing obatan, it controls drug launch and functions as a tablet binder. Ing panganan, it stabilizes solutions and enhances appearance.

Panyimpenan lan Penanganan

Store HPMC in an amazing, panggonan garing adoh saka Kelembapan. Maintain containers securely shut. The service life is generally 24 months when saved correctly. Avoid call with strong oxidizing representatives. Use common industrial health practices throughout handling.

Bahan Konstruksi

HPMC is widely made use of in building items like ceramic tile adhesives, cement plasters, lan zat self-leveling. It assists control water retention so cement can heal properly. This enhances workability and minimizes splitting. Contractors depend on HPMC to make mixes smoother and easier to spread out.

Obat-obatan

Ing obat, HPMC tumindak minangka binder, layer representative, or controlled-release component. It is secure for human usage and liquifies slowly in the body. Medication manufacturers include it to tablet computers to assist them hold form or launch medicine in time. Eye decreases likewise make use of HPMC to keep wetness on the eye surface area.

Pasar Pangan

HPMC jobs as a thickener, penstabil, or emulsifier in numerous foods. You can find it in sauces, dairy products alternatives, lan barang panggang. It aids maintain textures consistent and avoids active ingredients from dividing. Because it is plant-based and non-digestible, it matches vegan and low-calorie diet regimens.

Produk Perawatan Pribadi

Toothpaste, sampo, and creams usually consist of HPMC. It gives these products a smooth feeling and assists them remain combined. In toothpaste, it holds water and maintains the paste from drying out. Ing lotion, it develops a light movie that locks in dampness.

Agriculture

Panggunaan petani HPMC in seed finishes and pesticide formulas. It aids active ingredients adhere to plants and release gradually. This increases performance and cuts down on waste. Seed treatments with HPMC likewise sustain much better germination in dry conditions.

Paint lan Coatings

Paint manufacturers include HPMC to enhance structure and application. It quits pigments from settling and makes paint circulation uniformly. Wall surfaces obtain an uniform finish without drips or brush marks. The additive also assists paint withstand splashing during use.
