Overview
Food Grade White Oil 50# is a highly refined mineral oil derived from petroleum through extensive hydrotreatment to remove impurities. It is classified as a food-grade lubricant and processing aid, meeting stringent regulatory standards such as FDA 21 CFR §178.3620 and NSF H1. Its purity and inertness make it safe for incidental food contact, ensuring no contamination or alteration of taste, odor, or appearance of consumable products. This oil is distinguished by its viscosity grade (50#), which indicates its flow characteristics at specific temperatures. The 'food-grade' designation signifies it contains no additives harmful to human health, making it suitable for applications in food processing equipment, pharmaceuticals, and personal care products.
Physical and Chemical Properties
Food Grade White Oil 50# exhibits a colorless and odorless appearance, with a viscosity that ensures smooth lubrication under moderate to high temperatures. Its density ranges between 0.86-0.89 g/cm³, and it remains stable up to boiling points exceeding 300°C, making it suitable for thermal processes. The oil is insoluble in water but miscible with most organic solvents, enhancing its versatility in formulations. Key chemical properties include high oxidative stability, which prevents rancidity or degradation over time, and low volatility, minimizing evaporation losses. These traits ensure consistent performance in applications like bakery release agents or conveyor belt lubricants, where prolonged exposure to heat is common.
Main Applications
In the food industry, Food Grade White Oil 50# serves as a lubricant for machinery (e.g., mixers, slicers) to prevent wear while complying with hygiene standards. It acts as a release agent in baking molds and confectionery equipment, ensuring easy separation without residue. The oil also coats fruits and vegetables to extend shelf life by reducing moisture loss. Beyond food, it is used in pharmaceutical tablet coatings and cosmetic creams for its emollient properties. Industrial applications include textile fiber processing and rust prevention for metal equipment in food plants. Its non-reactive nature makes it ideal for sensitive environments where contamination risks must be eliminated.
Safety and Storage
Food Grade White Oil 50# is non-toxic when handled properly, but prolonged skin contact should be avoided to prevent irritation. Storage requires airtight containers in cool, dry areas (below 40°C) to maintain stability. Direct sunlight or extreme temperatures can degrade quality over time. For safety, ensure workspaces are well-ventilated to avoid mist inhalation. Spills should be contained with absorbent materials to prevent slips. Regulatory compliance (e.g., FDA, NSF) must be verified during procurement, as uncertified oils may pose health risks. Always follow manufacturer guidelines for disposal to minimize environmental impact.
B2B Procurement Guide
When sourcing Food Grade White Oil 50#, prioritize suppliers with certifications like NSF H1 or ISO 21469, which validate food-safe production processes. Bulk purchases (drums or totes) typically offer cost savings, with prices ranging ~$1,200-$1,800/ton depending on purity and quantity. Request technical datasheets to confirm viscosity, flash point, and other specs match your needs. Evaluate lead times and logistics, as some grades may require cold-weather shipping precautions. Establish long-term contracts with reliable vendors to ensure consistent quality. For niche applications (e.g., halal/kosher certification), specify requirements upfront. Sampling before large orders is advisable to test compatibility with your equipment or formulations.
