Definition & Composition
Solvent Oil is a refined petroleum distillate primarily composed of aliphatic and aromatic hydrocarbons.
- Key Properties:
- Low viscosity (typically 1–10 cSt at 40°C)
- High solvency power
- Low toxicity (non-carcinogenic grades)
- Flash point >60°C (non-flammable variants)
