Slaked Lime IP Grade | Calcium Hydroxide IP Standard

In the pharmaceutical industry, compliance with pharmacopoeial standards is essential. Every raw material must meet defined specifications to ensure safety, purity, and consistency.

Slaked Lime – IP Grade, also known as Calcium Hydroxide IP, is manufactured and tested according to the standards defined in the Indian Pharmacopoeia (IP). It is specially processed for use in pharmaceutical formulations, dental applications, and regulated industries where strict quality control is mandatory.

IP Grade Slaked Lime is not just hydrated lime — it is a precision-tested pharmaceutical ingredient.

What is Slaked Lime – IP Grade?

Slaked Lime is chemically known as Calcium Hydroxide (Ca(OH)₂). It is produced by controlled hydration of quicklime (calcium oxide):

CaO + H₂O → Ca(OH)₂

When manufactured as IP Grade, the product is:

• Tested as per Indian Pharmacopoeia specifications

• Controlled for heavy metals

• Checked for acid insoluble matter

• Verified for assay purity

• Monitored for loss on drying

• Supplied with Certificate of Analysis (COA)

Key Features of IP Grade Calcium Hydroxide

• High chemical purity

• Low impurities

• Strict heavy metal limits

• Fine particle size

• Stable alkaline properties

• Batch-to-batch consistency

• Regulatory documentation support

These properties make it suitable for sensitive pharmaceutical applications.

Applications of Slaked Lime – IP Grade

1. Pharmaceutical Formulations

Used in:

• Antacid preparations

• pH adjustment in medicinal formulations

• Chemical intermediates

• Topical pharmaceutical solutions

Its alkaline nature helps neutralize acidity and maintain product stability.

2. Dental Applications

IP Grade Calcium Hydroxide is widely used in:

• Root canal treatments

• Pulp capping

• Dental liners

• Cavity filling materials

Its high pH provides antibacterial properties, helping in infection control.

3. Laboratory & Research Use

• Chemical reagent applications

• Controlled experiments

• Analytical testing

Because of its defined purity, it ensures predictable results.

Why IP Grade Matters

In pharmaceutical manufacturing, even small deviations can cause:

• Product rejection

• Regulatory non-compliance

• Safety risks

• Financial losses
