Paraffin wax is one of the most widely used industrial waxes in the world. From candle manufacturing to packaging, rubber, cosmetics, and adhesives, its applications span across industries.
But for procurement professionals, product developers, and business owners, the key question is not what paraffin wax is — it’s which type is right for your application, and how to source it reliably.
In this guide, we’ll cover:
What paraffin wax is
Key parameters to evaluate
Common applications
How to choose the right grade
What to look for in a supplier
Paraffin wax is a crystalline, solid hydrocarbon derived from petroleum refining. It consists mainly of straight-chain alkanes (n-alkanes) and is characterized by its white, odorless, and tasteless nature.
It is valued for:
Thermal stability
Controlled melting points
Moisture resistance
Low cost relative to natural waxes
Not all paraffin wax is the same. The most common classification is based on oil content:
| Grade | Oil Content | Typical Applications |
|---|---|---|
| Fully Refined | ≤0.5% | Candles, food packaging, cosmetics, rubber |
| Semi-Refined | 0.5–2.0% | Industrial coatings, matchboxes, fiberboard |
| Scale Wax / Slack Wax | >2% | Base for further refining, low-cost industrial use |
Within fully refined paraffin, you’ll also encounter specifications like:
Melting point (e.g., 58–60°C, 60–62°C)
Needle penetration (hardness)
Oil content
Color (Saybolt color scale)
This is the largest consumer segment. Different candle types require different wax properties:
Pillar candles: High melt point, low oil content (e.g., 60–62°C fully refined)
Container candles: Lower melt point, often blended with additives
Tealights & votives: Hardness and burn consistency matter
Paraffin wax is used in moisture-proof coatings for food packaging, corrugated cardboard, and cheese coatings.
Used as a ozone-protection agent, paraffin wax migrates to the surface to prevent cracking in tires and industrial rubber goods.
High-purity, fully refined paraffin is used in lip balms, creams, and ointments as a thickening and occlusive agent.
Paraffin wax modifies viscosity and setting time in hot melt adhesives for packaging and woodworking.
When evaluating paraffin wax for a specific application, consider these five parameters:
Melting Point
Higher melt point = better thermal stability, suitable for pillars and molded products. Lower melt point = easier processing.
Oil Content
Lower oil content means higher hardness and cleaner burn — critical for candles and food contact applications.
Color & Purity
Fully refined wax should be water-white (Saybolt +25 or higher). Off-color wax may indicate impurities.
Needle Penetration
Measures hardness. Harder waxes (lower penetration) are better for molded candles; softer waxes work well for blends.
Regulatory Compliance
For food, cosmetic, or pharmaceutical use, ensure the wax meets FDA, Halal, Kosher, or other applicable standards.
Buyers often compare paraffin wax with microcrystalline wax.
| Property | Paraffin Wax | Microcrystalline Wax |
|---|---|---|
| Crystal structure | Large, coarse | Small, fine |
| Oil content | Lower | Higher |
| Flexibility | Brittle | Flexible, tacky |
| Applications | Candles, packaging, rubber | Adhesives, cosmetics, pipe coatings, investment casting |
In many cases, the two are blended to achieve specific performance characteristics.
A reliable supplier should provide:
Consistent specifications from batch to batch
COA (Certificate of Analysis) for each shipment
Clear documentation on oil content, melt point, and purity
Flexibility in packaging (slabs, pastilles, liquid)
Supply chain transparency — especially important for B2B buyers managing production schedules
If you are sourcing for export, also verify:
Packaging suitable for ocean freight
Availability of Halal, Kosher, or food-grade certifications if required
Lead times and MOQ (Minimum Order Quantity)
