Versatile Industrial Applications

Calcium Hydroxide (USP Grade) serves as a critical ingredient in pharmaceuticals, food manufacturing, chemical synthesis, cosmetics, and water treatment. Its unique alkaline properties and low toxicity make it essential for products that require stabilization, pH adjustment, or neutralization.

Outstanding Chemical Stability

This product remains stable under normal temperature and pressure, while its ability to absorb CO2 from air ensures consistent efficacy for sensitive industrial and laboratory operations. Its compliance with USP requirements guarantees high purity and safety.

Safe Packaging and Storage

Packaged in 25 or 50 kg HDPE bags with inner liners, Calcium Hydroxide is protected from moisture and carbon dioxide, preserving its quality and prolonging shelf life. Proper storage ensures up to two years of usability.

FAQs of Calcium Hydroxide (USP Grade):

Q: How is Calcium Hydroxide (USP Grade) commonly used across industries?

A: Calcium Hydroxide (USP Grade) is widely employed as an antacid, pH adjuster, food additive (E526), water softener, and stabilizer. It finds applications in pharmaceuticals, food processing, water treatment, cosmetics, and various chemical industries.

Q: What are the benefits of using USP Grade Calcium Hydroxide in formulations?

A: The main benefits include its high purity (min. 95%), low toxicity, excellent alkalinity, and compliance with stringent heavy metal limits as per USP requirements. It provides reliable pH control and stabilization in pharmaceutical and food products.

Q: Where and how should Calcium Hydroxide be stored for maximum shelf life?

A: Store the powder in tightly sealed 25/50 kg HDPE bags with inner liners, in a dry, cool environment away from acids, moisture, and incompatible materials. Proper storage maintains its efficacy for up to two years.

Q: When should Calcium Hydroxide not be used in a process?

A: It should be avoided in reactions involving acids, ammonium salts, aluminum, or in humid conditions, as these can initiate unwanted reactions or compromise its stability.

Q: What safety measures are recommended during handling and usage?

A: While Calcium Hydroxide is non-poisonous and has low toxicity, it is strongly alkaline and highly reactive. Use standard protective equipment, avoid inhalation or contact with eyes and skin, and handle in well-ventilated areas.

Q: How does Calcium Hydroxides reactivity with CO2 in air affect its storage or use?

A: Calcium Hydroxide readily absorbs CO2 from air, forming calcium carbonate. This may decrease its active concentration, so it should always be stored in airtight containers to maintain product effectiveness.
