Base Oil SN 70 – Light Neutral Oil for Lubricant Blending

Base Oil SN 70 in red steel drums prepared for export with quality inspection by Basekim.

Base Oil SN 70 is a light neutral mineral base oil designed for industries that need smooth flow, high clarity, and stable performance at an affordable cost. Because it has low viscosity, pale color, and excellent oxidation resistance, manufacturers widely use Base Oil SN 70 in lubricants, hydraulic fluids, cosmetic oils, textile oils, and blending formulations. This grade works especially well when products must remain fluid at lower temperatures and maintain consistent quality over time. As a result, SN-70 Base Stock plays a key role in both industrial production and consumer-grade oil formulations.

Unlike heavier base oils, SN 70 flows easily, mixes quickly with additives, and supports clean, stable finished products. Therefore, it is a practical and reliable choice for companies that value performance, flexibility, and commercial efficiency.

What Is Base Oil SN 70?

Base Oil SN 70 is a Group I solvent neutral base oil produced from carefully selected crude oil fractions. Refineries manufacture it through solvent extraction, hydrotreating, and dewaxing processes. These steps remove impurities such as aromatics, sulfur, and waxes, resulting in a clear, stable, and light base oil.

The term SN stands for Solvent Neutral, while 70 refers to its low viscosity grade. Because of this light structure, SN 70 offers:

  • Smooth flow at low and moderate temperatures

  • Easy blending with additives and heavier base oils

  • Clean appearance suitable for sensitive applications

For this reason, manufacturers use SN-70 Base Stock as a foundation oil in many formulations where purity and flow matter most.

Key Technical Properties of Base Oil SN 70

Although Base Oil SN 70 is light, it still provides dependable performance across many applications. Its balanced structure allows it to perform consistently in both technical and consumer products.

Main Characteristics

  • Low viscosity – ideal for thin-film lubrication and fast circulation

  • Good viscosity index – stable performance across temperature changes

  • Excellent oxidation stability – resists degradation during use

  • Low volatility – reduces evaporation and oil loss

  • Pale color and clear appearance – suitable for white oils and cosmetics

  • Strong additive compatibility – blends easily with chemical packages

Because of these qualities, SN-70 Base Stock supports long service life and stable product behavior.

Typical Specifications of Base Oil SN 70

While exact values may vary slightly by refinery, SN-70 Base Stock generally meets international industry expectations.
