– hrana: As a thickener or stabilizer (kjer je dovoljeno).
– Individual treatment: V šamponih za lase, losjoni, and tooth paste for texture control.

Storage needs to remain in an amazing, dry location in secured containers to prevent moisture uptake. Service life is usually 24 months under appropriate problems.

Applications of Chemical Raw Material Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Uporaba hidroksipropil metil celuloze (HPMC)– CAS 9004-65-3

Gradbeništvo in gradbeni izdelki

HPMC is commonly made use of in cement-based products like tile adhesives, samorazlivne mase, in obliži. It enhances workability by retaining water throughout the healing procedure. This aids prevent cracks and makes certain strong bonding. Building contractors rely on HPMC for constant performance in dry-mix mortars.

Farmacevtski izdelki

V medicini, HPMC work as a binder, predstavnik filmskih premazov, ali matriko z nadzorovanim sproščanjem v tabličnih računalnikih. It liquifies gradually in the digestive system system, permitting drugs to launch continuously over time. The compound is safe and approved for use in oral medicines worldwide.

Živilska industrija

HPMC služi kot zgoščevalec, emulgator, and stabilizer in lots of refined foods. It assists keep appearance and protects against component splitting up in items like sauces, sladoled, in pekovskih izdelkov brez glutena. Regulative agencies acknowledge it as risk-free for consumption under particular use degrees.

Barve in premazi

Repaint producers include HPMC to water-based formulations to regulate thickness and enhance application. It stops pigments from working out and offers a smooth surface. The additive additionally boosts open time, allowing painters function much longer prior to the covering dries out.

Kozmetika in osebna nega

V losjonih, šamponi, and toothpaste, HPMC supplies structure and stability. It produces a pleasant feeling on the skin or hair without triggering irritability. Its ability to form clear gels makes it suitable for clear cosmetic items.
