What is White Oil

White oil, often misunderstood due to its name, is actually a crystal clear substance. It is known variously as liquid paraffin wax, mineral oil, or by scientific names like paraffinum perliquidum. In addition, it stands out for being colorless, odorless, and tasteless. It is a blend of saturated paraffinic and naphthenic hydrocarbons, refined meticulously to achieve purity and stability. With a viscosity range of 50-370 SUS at 100°F, white oil is notable for its near absence of nitrogen, sulfur, oxygen, and aromatic hydrocarbons.

Properties of White Oil

• Chemical Inertness: Remarkably free from reactive elements like nitrogen, sulfur, and oxygen.
• Purity: Its refining process eliminates almost all impurities.
• Thermal Stability: Can withstand varying temperatures without altering its chemical structure.
• Odorless and Tasteless: Lacks any distinct smell or taste.
• Viscosity: Maintains a consistent viscosity within a specific range.
• Colorless: Contrary to its name, white oil is crystal clear.

Production Process

White oil is produced through a sophisticated refining process. Starting with various feedstocks, ranging from conventional base stocks to Vacuum Gas Oils (VGO), it undergoes either the older acid treatment process or the more modern two-stage hydrotreating method. Both methods are dedicated to removing detrimental components like aromatics and sulfur, ensuring the oil’s purity and thermal stability.

Identifying White Oil

To correctly identify white oil, look for its characteristic features: a colorless, odorless liquid with a smooth, non-greasy texture. It should be free from impurities and not react with other substances, indicative of its high refinement level.

Applications in Different Industries

White oil finds its utility in a wide range of industries due to its unique properties like purity, stability, and inertness. 

1. Cosmetics Industry

White oil is a popular ingredient in cosmetic products due to its non-toxic and non-irritating nature.
