In the pharmaceutical industry, purity is not optional — it is mandatory. Every ingredient must meet strict standards for safety, consistency, and regulatory compliance.

Slaked Lime – Pharma Grade, also known as Pharmaceutical Grade Calcium Hydroxide (Ca(OH)₂), is a highly purified alkaline compound manufactured under controlled conditions and tested as per IP, BP, and USP standards.

Since 1948, Vigyan Lime has been a trusted manufacturer of high-purity lime and industrial minerals, supplying regulated industries across India and overseas markets.

What is Slaked Lime – Pharma Grade?

Slaked lime is produced by hydrating quicklime (Calcium Oxide) with controlled water addition:

CaO + H₂O → Ca(OH)₂

Pharma grade calcium hydroxide differs from industrial grade due to:

• High assay purity

• Strict heavy metal control

• Low insoluble impurities

• Microbiological safety

• Controlled particle size

• Full documentation & traceability

This ensures suitability for pharmaceutical and regulated applications.

Why Pharma Grade Quality is Critical

In pharmaceutical manufacturing:

• Even minor impurities can affect product stability

• Heavy metals must remain within strict limits

• Batch consistency is essential

• Compliance documentation is mandatory

Pharma Grade Slaked Lime undergoes:

• Assay testing

• Loss on drying test

• Acid insoluble matter test

• Heavy metal analysis

• Microbial testing

• COA verification before dispatch

Applications of Pharma Grade Slaked Lime

1. Pharmaceutical Formulations

Used in:

• Antacid preparations

• pH adjustment in formulations

• Chemical intermediate manufacturing

• Topical solutions

Its strong alkaline nature helps maintain controlled pH environments.

2. Dental Applications

Calcium hydroxide is widely used in:

• Root canal treatment

• Pulp capping

• Dental cement

• Cavity lining

Its antibacterial properties help protect tooth pulp and prevent infection.

3. Regulated Food & Processing Applications

Where permitted by regulatory standards, pharma grade lime may be used in:

• Sugar refining

• Pickling processes

• Corn processing (nixtamalization)

• Food-grade processing environments
