Dried Aluminium Hyroxide Gel

Whatsapp Order

Dried Aluminium Hyroxide Gel is a highly purified, finely dispersed aluminum hydroxide product obtained by drying aluminum hydroxide gels. It is a white, amorphous, odorless powder with excellent adsorptive and neutralizing properties. This material serves as an effective antacid, a flame retardant filler, and an adsorbent in pharmaceutical, cosmetic, and industrial applications. Its gel form ensures high surface area and porosity, making it highly reactive and efficient in acid neutralization and catalysis. Dried Aluminum Hydroxide Gel is widely used for its buffering capacity and chemical inertness in various formulations.

Dried Aluminium Hyroxide Gel

Primary Uses

Pharmaceuticals

Used as an active antacid ingredient for neutralizing gastric acid in formulations such as tablets, suspensions, and gels.
Functions as a buffering agent to maintain pH stability in oral and topical pharmaceutical products.
Acts as an adsorbent for toxins and gases in gastrointestinal treatments.

Cosmetics & Personal Care

Utilized as an opacifying and bulking agent in creams, lotions, and powders.
Used for its skin-soothing and mild astringent properties in deodorants and antiperspirants.
Functions as a thickener and stabilizer in gel and cream formulations.

Industrial Applications

Acts as a flame retardant filler in plastics, rubber, and coatings, enhancing fire resistance by releasing water on heating.
Used as a pigment and filler in paints and coatings to improve durability and coverage.
Serves as a catalyst support or component in chemical syntheses and water treatment processes.

Food Industry

Employed as an anti-caking agent or processing aid (only when food-grade specifications are met).
Used to neutralize acidity in certain food processing applications.

Secondary Uses

Water Treatment

Used as a coagulating agent and flocculant to remove impurities and heavy metals from wastewater.

Rubber & Plastics

Acts as a reinforcing agent to improve mechanical properties and weather resistance of elastomers.

Paper Industry

Used as a coating pigment and filler to enhance brightness and opacity of paper products.
