White Oil[2]
Overview
White Oil is a premium-grade mineral oil derived from petroleum through extensive refining processes, including hydrotreatment and distillation. It is free from impurities like sulfur, aromatics, and unsaturated hydrocarbons, making it suitable for sensitive applications such as personal care and food contact. Its versatility stems from its inert nature, ensuring compatibility with diverse formulations without causing oxidation or degradation. Industries value White Oil for its consistent performance in extreme temperatures and resistance to microbial growth.
Physical and Chemical Properties
White Oil is characterized by its transparency, low viscosity (for lightweight grades) to high viscosity (for heavy grades), and negligible volatility. It exhibits excellent dielectric properties and remains stable under UV exposure, making it ideal for electrical insulation and outdoor applications. The oil's hydrocarbon composition (primarily alkanes and cycloalkanes) ensures minimal reactivity, even in aggressive chemical environments. Its flash point typically exceeds 200°C, enhancing safety in high-temperature operations.
Main Applications
In cosmetics, White Oil serves as a base for creams, lotions, and baby oils due to its hypoallergenic properties. Pharmaceutical grades are used in laxatives and ointments, while food-grade variants lubricate machinery in food processing plants. Industrially, it acts as a release agent in plastics manufacturing, a dust suppressant in textiles, and a corrosion inhibitor in metalworking. Its water-repellent nature also benefits agricultural sprays and adhesive formulations.
Safety and Storage
Food-grade White Oil complies with FDA 21 CFR §172.878 and EU Directive 2008/84/EC, ensuring safe ingestion or topical use. Industrial grades may require PPE (gloves, goggles) to prevent prolonged skin contact. Storage tanks should be constructed from carbon steel or polyethylene, with nitrogen blanketing recommended for long-term preservation. Avoid contamination with water or particulates to maintain purity.
B2B Procurement Guide
Buyers should prioritize suppliers with ISO 9001 certification and batch-specific analysis reports. Key specifications include viscosity index, pour point, and UV absorbance (for USP grades). Bulk purchases (drums, totes) offer cost savings, while smaller quantities (bottles, cans) suit niche applications. Negotiate MOQs and lead times, especially for customized viscosities or additives like antioxidants.
