Description
Paraffin wax is a white or colorless, soft solid wax made from petroleum. It is odorless, tasteless, and highly water-resistant. It melts easily and is widely used in candles, cosmetics, polishes, waterproof coatings, packaging, crayons, and spa treatments. Its smooth texture and stable burning make it one of the most common industrial and household waxes

Uses
Candle Industry
Paraffin wax is one of the primary materials for making candles. Its smooth texture, colorless/white appearance, and stable burning make it ideal for tealights, decorative candles, and household candles. It can be easily blended with dyes and fragrances for customized candles.
Cosmetics & Personal Care
In the cosmetics industry, paraffin wax is used in lip balms, creams, lotions, ointments, and hair care products. It provides a protective barrier on the skin, retains moisture, and improves texture and consistency of formulations.
Packaging Industry
Paraffin wax is used to coat paper, cardboard, and corrugated sheets to make them moisture-resistant and grease-proof. It is also used in food packaging, such as candy wrappers and waxed paper for fruits and cheese.
Rubber & Tire Industry
Paraffin wax is added to rubber and tire formulations to enhance elasticity, prevent cracking, and improve durability. It also acts as a processing aid during manufacturing.
Textile Industry
In textiles, paraffin wax is applied to fabrics, threads, and yarns to make them water-resistant. It is used in fabric finishing and sizing operations to improve feel and handling.
Pharmaceutical Industry
Paraffin wax serves as a tablet coating, suppository base, and ointment ingredient. Its inert and stable nature ensures drug stability and controlled release in medicinal formulations.
Polishes & Coatings
Paraffin wax is a key component in floor polish, shoe polish, furniture wax, and protective coatings. It provides a smooth finish, water repellency, and gloss.
Art Supplies
It is used in making crayons, wax crayons, encaustic paints, and wax-based modeling materials due to its non-toxic and moldable properties.
Food Industry
Paraffin wax is applied as a coating on cheese, fruits, candies, and chocolates to prevent moisture loss, maintain freshness, and protect from external contamination.
Electrical & Electronics Industry
Paraffin wax is used for insulating wires and components and as a sealing agent in transformers and other electrical equipment due to its non-conductive and stable nature.
Lubricants & Greases
It acts as an additive in greases, lubricants, and mold-release agents, improving smoothness, stability, and water resistance
Industrial Protection
Paraffin wax is applied for corrosion prevention, metal coating, and mold casting, protecting surfaces from moisture and chemical damage.
Grades of Paraffin wax
Fully Refined Paraffin Wax
Purity: Very high; oil content <0.5%
Appearance: White or colorless, odorless
Melting Point: 46–68°C depending on type
Uses: Candles, cosmetics, food coatings, polishes
Notes: Highly stable, non-toxic, and preferred for applications requiring safety and aesthetic quality
Semi-Refined Paraffin Wax
Purity: Moderate; oil content 0.5–1.5%
Appearance: Slightly yellowish
Melting Point: 46–68°C
Uses: Industrial coatings, packaging, adhesives, general industrial applications
Notes: Less expensive than fully refined; may have slight odor and color
Slack Wax
Purity: Low; contains a high percentage of oil and unrefined hydrocarbons
Appearance: Yellow to dark, semi-solid or sticky
Melting Point: Variable
Uses: Raw material for refining into fully or semi-refined paraffin; used in industrial lubricants, coatings, and rubber processing
Notes: Requires further processing for food or cosmetic use
Microcrystalline Wax
Purity: Variable; higher oil content than normal paraffin wax
Appearance: Fine, small crystals; soft and flexible
Melting Point: 60–90°C
Uses: Cosmetics, adhesives, flexible coatings, rubber additives, ointments
Notes: More flexible than normal paraffin wax due to smaller crystals; excellent binding properties
Hard Wax (High Melting Point)
Purity: Refined
Appearance: Hard and brittle
Melting Point: 60–70°C or higher
Uses: Candles, waterproof coatings, industrial applications
Notes: Stable at higher temperatures; provides structural strength in candles and coatings
Soft Wax (Low Melting Point)
Purity: Refined
Appearance: Soft, pliable
Melting Point: 46–58°C
Uses: Cosmetics, ointments, food coatings
Notes: Easy to blend with oils and other ingredients; melts at low temperature for skin or food applications
