Hydroxypropylmethylcellul ose - China

HPMC Powder

Hydroxypropylmethylcel lulose (HPMC) is multifunctional and can be used as a lubricant, foam booster and stabilizer, thickener, emulsion stabilizer, and film-former in hair and skin care products.

HPMC is particularly useful in surfactant systems because of its foam-enhancing properties, which help to form a bubbly structure, resulting in richer, longer-lasting foams.

HPMC is highly tolerant to salts and alcohols.

HPMC has a high tolerance to salt and alcohol.

Techniques for Dispersion

The preferred method is to begin by heating approximately 1/3 of the total formulation water to 167°F (75°C) or higher.

Add the HPMC to the vortex of agitated and heated water.

Mix until fully dispersed.

HMPC will not dissolve at this temperature.

After complete dispersion, add the remaining water at room temperature or colder and continue mixing for 30 minutes after the total solution has cooled to 77°F.

(25°C) or less.

Proceed with the formulation.

If heating is impossible, it is preferred to slurry the HPMC in a non-solvating media, such as glycerin or PEG, then add the slurry to the vortex of vigorously agitated water.

Adding HPMC directly to cold water is not preferred, but if necessary, must be done very slowly under vigorous agitation.

Expect longer mixing times for complete dissolution.

Hydroxypropylmethylcel lulose (HPMC) is a cellulose ether in which the hydroxyl group on the cellulose chain has been replaced by either methoxy or hydroxypropyl groups.

HPMC is used as a thickener, binder, and film-former in agrochemicals, coatings, ceramics, adhesives, inks, and a wide variety of other applications.

An aqueous solution of HPMC undergoes a reversible gelation on exposure to heat to controllably increase the raw strength of raw ceramics bodies.
