Name: Dow METHOCEL 40-0202 Hydroxypropyl Methylcellulose
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow METHOCEL 40-0202 Hydroxypropyl Methylcellulose

Highly water-soluble nonionic polymer with excellent cold-water dispersion and rapid hydration kinetics.
Provides robust thermal gelation behavior, forming reversible gels upon heating and re-dissolving upon cooling.
Delivers consistent viscosity performance across broad pH range (3–11) and in presence of moderate electrolytes.
Offers superior film-forming capability with good flexibility, clarity, and low residual odor.
Complies with USP/NF, EP, JP, and FDA 21 CFR 172.874 for use in pharmaceutical and food applications.

Typical Applications Of Dow METHOCEL 40-0202 Hydroxypropyl Methylcellulose

Immediate-release and sustained-release oral solid dosage forms (tablets, granules, matrix tablets).
Topical gels, creams, and ointments requiring thermoreversible rheology and water retention.
Food-grade thickener and stabilizer in dairy alternatives, sauces, and plant-based beverages.
Construction adhesives and tile-setting mortars where open time extension and sag resistance are critical.
Personal care formulations including toothpaste, shampoos, and hand sanitizers for viscosity control and suspension.
