Heavy Liquid Paraffin: Applications and Properties

High-quality heavy liquid paraffin with wide-ranging applications in hygiene, pharmaceutical, textile, candle-making, and lubrication industries. Discover the characteristics and uses of this heavy petroleum product with high viscosity

and guaranteed purity.

What is Heavy Liquid Paraffin?

Heavy Liquid Paraffin is a petroleum distillate classified as a type of mineral oil. It is a colorless, odorless, transparent substance with high density and viscosity. Unlike light paraffin, it is derived from heavier petroleum cuts, making it

more suitable for applications requiring durability, thicker coating, or stronger lubrication.

This paraffin—also known as heavy paraffin oil, heavy mineral oil, or industrial-grade heavy liquid paraffin—is widely used across various industries due to its stable properties. In many cases, its refined grade is also used in edible or

pharmaceutical applications.

Physical and Chemical Properties of Heavy Liquid Paraffin

Heavy paraffin possesses distinct properties that set it apart from other types of paraffin. The most notable characteristics include:

High density: Typically greater than 0.86 g/cm³, which enhances surface adhesion and longevity.
High viscosity: Enables more effective lubrication compared to light paraffin.
High flash point: Usually over 200°C, making it safer for industrial use.
Colorless and odorless: Ideal for use in cosmetics, healthcare, and pharmaceuticals.
High chemical stability: Resistant to oxidation and highly non-reactive.
Free of sulfur and aromatics: In medical and pharmaceutical grades, it contains no sulfur compounds or aromatic hydrocarbons.

Types of Liquid Paraffin by Viscosity

Liquid paraffin is generally classified into two main types:

Light Liquid Paraffin:
Lower viscosity, more fluid, used in pharmaceutical, cosmetic, and light industrial applications.
Heavy Liquid Paraffin:
Higher viscosity and density, suitable for industrial, hygienic, emollient, and stronger lubricant applications.

This classification is sometimes referred to as light and heavy paraffin or, in some sources, as macrocrystalline (light) and microcrystalline (heavy) paraffin, though these terms are more commonly used for solid paraffin.

Applications of Heavy Liquid Paraffin
Due to its unique properties, heavy liquid paraffin plays a key role in many industries and manufacturing processes:

Cosmetic and Personal Care Industry:
Used as an oil base, moisturizer, and stabilizer in creams, lotions, massage oils, ointments, and skin softeners. Its high skin compatibility makes it a preferred choice in hygiene products.
Pharmaceutical Industry:
In pharma-grade form, it is used as a carrier in laxatives, topical ointments, gels, and suppositories. It must comply with pharmaceutical standards and be free of harmful impurities.
Industrial Lubrication:
Serves as a lubricant for light industrial machinery, moving chains, precision tools, and metalworking processes. Its high viscosity helps reduce friction and prolong component life.
Textile and Leather Industry:
Functions as a lubricant and softener during textile fiber processing and in synthetic leather production or natural leather finishing.
Candle and Match Production:
Used as an additive in specialized candles to improve burn quality, extend burn time, and reduce soot.
Rust Prevention and Coating:
Provides temporary protection for metal parts against moisture and corrosion by forming a thin yet stable coating layer.
