Slaked Lime BP Grade | Calcium Hydroxide BP Standard

In the pharmaceutical world, trust is built on standards. When a raw material complies with the British Pharmacopoeia (BP), it means it has passed strict quality benchmarks recognized internationally.

Slaked Lime – BP Grade, also known as Calcium Hydroxide BP, is a highly purified form of hydrated lime manufactured and tested according to British Pharmacopoeia specifications. It is widely used in pharmaceutical, dental, and regulated chemical applications where precision, safety, and compliance are essential.

This is not ordinary lime — it is a carefully processed pharmaceutical-grade ingredient designed for industries where quality cannot be compromised.

What is Slaked Lime – BP Grade?

Slaked Lime is chemically known as Calcium Hydroxide (Ca(OH)₂). It is produced by adding water to quicklime under controlled conditions:

CaO + H₂O → Ca(OH)₂

When manufactured as BP Grade, it must meet defined parameters for:

• Assay (purity level)

• Heavy metal limits

• Insoluble matter

• Chlorides and sulfates

• Loss on drying

• Controlled alkalinity

Each batch is tested and documented to ensure compliance with British Pharmacopoeia standards.

Why BP Grade Matters

For pharmaceutical companies supplying to international markets, BP compliance provides:

✔ International credibility
✔ Regulatory acceptance
✔ Export suitability
✔ Consistent chemical performance

When exporting finished medicines to Europe or Commonwealth countries, using BP-compliant raw materials simplifies regulatory approvals and audits.

Key Features of BP Grade Calcium Hydroxide

• High chemical purity

• Strict impurity control

• Heavy metals within defined limits

• Fine and uniform particle size

• Strong alkaline stability

• Batch-to-batch consistency

• COA (Certificate of Analysis) with BP reference

Applications of Slaked Lime – BP Grade

1. Pharmaceutical Formulations

Used in:

• Antacid preparations

• pH adjustment systems

• Medicinal chemical synthesis

• Controlled neutralization reactions

Its alkaline nature makes it effective for acidity control and formulation stability.

3. Dental Applications

BP Grade Calcium Hydroxide plays a critical role in:

• Root canal treatments

• Pulp capping procedures

• Dental cement formulations

• Cavity lining materials

Its high pH creates an antibacterial environment, helping protect dental pulp.

3. Regulated Chemical & Laboratory Use

Because of its defined purity, BP Grade Slaked Lime is suitable for:

• Analytical laboratory testing

• Pharmaceutical R&D

• Controlled manufacturing environments

Manufacturing Process of BP Grade Slaked Lime

Producing BP Grade material requires precision at every step:

1. Selection of high-purity limestone

2. Controlled calcination to produce high-quality quicklime

3. Precision hydration process

4. Micronization for uniform particle size

5. Multi-stage laboratory testing

6. Moisture-proof hygienic packaging

Every batch is validated before release.

Difference Between Industrial & BP Grade Lime

Choosing the correct grade protects your product quality and brand reputation.

Packaging & Supply
