Dried Aluminium Hyroxide Gel

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.

Description

SAFETY HANDLING PRECAUTIONS

Safety Handling Precautions

PPE Required:

  • Dust mask or respirator (to prevent inhalation of fine powder)

  • Safety goggles

  • Gloves (nitrile or latex)

  • Protective clothing or lab coat

Handling Guidelines:

  • Avoid creating dust clouds during handling

  • Use dust extraction or local exhaust ventilation when handling bulk powder

  • Do not ingest or inhale powder

  • Avoid contact with eyes and skin

Storage Measures:

  • Keep containers tightly closed and dry

  • Store away from acids and moisture to prevent chemical reactions

  • Avoid exposure to heat sources

Hygiene Practices:

  • Wash hands thoroughly after handling

  • Do not eat, drink, or smoke in areas where the product is handled

  • Clean work surfaces regularly to minimize dust accumulation

First Aid Measures

  • Inhalation: Move to fresh air; seek medical attention if breathing difficulty or irritation occurs

  • Skin Contact: Wash skin with soap and water; seek medical advice if irritation develops

  • Eye Contact: Rinse eyes with plenty of water for at least 15 minutes; seek medical attention if irritation persists
