SHORT DESCRIPTION

Paraffin Wax Extra Pure is a refined, high-purity hydrocarbon compound derived from petroleum. It appears as a white, odorless, and tasteless solid with a smooth, waxy texture and a relatively low melting point, making it easy to mold and blend with other substances.

This Extra Pure grade is especially suited for laboratory use, cosmetic formulations, pharmaceutical applications, and specialized industrial processes. It is commonly employed in the preparation of ointments, candles, sealing agents, and coating materials due to its excellent insulating, water-repellent, and moisture-barrier properties. Its chemical inertness also makes it a safe choice for embedding biological samples and for use as a lubricant or mold-release agent. Paraffin Wax should be stored in a cool, dry place, away from heat sources, and handled with care to prevent unwanted melting or contamination.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Wear a lab coat, heat-resistant gloves (if handling molten wax), and safety goggles.
Use a dust mask or ensure good ventilation if heated or processed.

Handling:

Handle with care to avoid spills and splashes.
Avoid inhalation of vapors or fumes when heated.
Do not overheat to avoid thermal decomposition.
Wash hands after handling.

Storage:

Store in a cool, dry, and well-ventilated area.
Keep the container tightly closed.
Protect from open flames, high heat, and direct sunlight.
Keep away from oxidizing agents.

FIRST AID MEASURES

Inhalation:

Move the person to fresh air.
If respiratory symptoms occur, seek medical advice.

Skin Contact:

For solid wax: Wash with soap and water.
For molten wax: Cool affected area with water, do not remove wax forcibly.
Seek medical attention for burns or irritation.

Eye Contact:

Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do.
Seek medical attention if irritation persists.

Ingestion:

Rinse mouth with water.
Do not induce vomiting.
Seek medical attention if symptoms occur.

FIRE FIGHTING MEASURES

Flammability:

Combustible solid—can catch fire at high temperatures.

Extinguishing Media:

Use dry chemicals, CO₂, or foam.
Do not use a direct water jet on molten wax—it may cause splattering.

Hazardous Combustion Products:

May emit carbon monoxide and carbon dioxide when burned.

Firefighter Protection:

Wear self-contained breathing apparatus (SCBA) and full protective gear.
