White oil 15 manufacturers

White Oil 15 is defined by its kinematic viscosity, which should be approximately 13-18 cSt at 40°C. Buyers must verify the purity levels, ensuring the oil is colorless, odorless, and tasteless. Key parameters include a flash point above 170°C for safety and a pour point below -10°C for stability in cold environments. Always request a Certificate of Analysis (COA) to confirm the specific gravity (typically 0.820–0.860) and the absence of fluorescence under UV light.

For food-grade applications, the oil must meet FDA 21 CFR 172.878 or 178.3620(a) regulations. For pharmaceutical or cosmetic use, compliance with USP (US Pharmacopeia), BP (British Pharmacopeia), or EP (European Pharmacopeia) standards is essential. If the product is intended for the EU market, ensure the supplier is REACH compliant to avoid customs seizures. Additionally, NSF H1 registration is required if the oil is used as a lubricant with incidental food contact.

The quality is determined by the degree of hydro-treatment. High-grade White Oil 15 undergoes severe hydro-cracking to remove aromatic hydrocarbons, sulfur, and nitrogen impurities. This results in a high UV absorbance stability, meaning the oil will not yellow or degrade when exposed to light. For B2B buyers, it is critical to distinguish between Technical Grade (used in plastics/polymers) and Medical/Food Grade (highly refined) to ensure the product is fit for the intended usage scenario.

White Oil 15 is highly versatile. In the cosmetics industry, it serves as a base for baby oils, lotions, and creams due to its non-comedogenic properties. In the food industry, it is used as a release agent for dough or a coating for fruits. In plastics manufacturing, it acts as an external lubricant and plasticizer for polystyrene and thermoplastic elastomers. It is also widely used in textile fiber lubrication and as a carrier for agricultural insecticides.

The primary risk is specification mismatch, where the delivered viscosity or purity does not match the sample. To mitigate this, use third-party inspection services (like SGS or Intertek) to test the cargo at the loading port. Another risk is leakage during transit; ensure the supplier uses UN-approved steel drums or ISO tanks with proper sealing. Lastly, be aware of fluctuating crude oil prices, which directly impact the cost of mineral oil derivatives.

When sourcing via Made-in-China.com, prioritize Audited Suppliers with verified production capacities. Negotiate based on volume-tiered pricing; for example, ordering a full 20ft container (FCL) can reduce unit costs by 15-20% compared to LCL. Request a long-term supply contract to lock in prices against market volatility. Always clarify the Incoterms (e.g., FOB vs. CIF) to understand exactly who covers the insurance and freight costs.

You must ensure the supplier provides a comprehensive Material Safety Data Sheet (MSDS) that aligns with the GHS (Globally Harmonized System). Other essential documents include the Commercial Invoice, Packing List, Bill of Lading, and the Certificate of Origin. For chemical products, customs may also require a Non-Hazardous Chemical Declaration if the flash point is high enough to classify it as non-flammable for transport.

Utilize secure payment methods such as Letters of Credit (L/C) for large volumes or Escrow services provided by the platform to ensure funds are only released upon proof of shipment. Regarding logistics, for liquid chemicals, Flexitanks are often the most cost-effective method for bulk shipping compared to traditional drums, as they maximize the volume within a standard container. Ensure the shipping line is experienced in handling liquid bulk cargo to prevent delays.
