What are food-grade lubricants?
Food-grade lubricants are specially formulated for safe use in the food and beverage industry. They reduce friction and protect production equipment from corrosion, moisture, and contaminants.
While their manufacturing process is similar to that of conventional lubricants, food-grade variants use carefully selected, high-quality raw materials that are free from harmful substances. These lubricants are rigorously tested and certified to meet strict safety and performance standards.
Interflon's food-grade lubricants and cleaners are specifically designed to withstand the demanding conditions of food processing plants and beverage factories. They are capable of enduring daily cleaning routines involving pressure washers, hot water, and even aggressive chemicals.

Frequently Asked Questions about food-grade lubricants
NSF 537 matters because it is NSF International’s PFAS-free certification standard for lubricants, introduced in 2025. It independently verifies that a lubricant contains no intentionally added PFAS substances. Unlike a supplier’s own PFAS-free claim, NSF 537 certification is publicly verifiable via NSF’s online listings and provides documentation that supports supplier approval processes, HACCP audits, and GFSI-aligned quality systems.
Interflon is the world’s first lubricant supplier to achieve NSF 537 certification across a complete H1 and 3H food-grade range.
The NSF classification categorizes lubricants into distinct classes based on their intended use within the food processing industry.
- NSF H1 Classification: Incidental Food Contact
Lubricants suitable for situations where incidental contact with food may occur. The trace level of the lubricant in the final product may not exceed 10 ppm. - NSF H2 Classification: No Food Contact
These lubricants are permitted for use within the food processing industry, but only in areas where no potential for food contact exists. - NSF H3 Classification: Direct Food Contact
Designed for scenarios where contact with food during production is unavoidable,. These lubricants must solely contain edible oils (soybean, corn, cottonseed) or specific mineral and Generally Recognized As Safe (GRAS) oils. - NSF 3H Classification
Applies to release agents, substances with the potential for incidental food contact (up to 100 ppm). Common applications include treatment of knives, meat grinders, and similar equipment to prevent food adhesion.
Yes. But manufacturers must demonstrate they have taken measures to prevent contamination. In the absence of such measures, H1 lubricants are generally recommended.
No, an NSF registration does not automatically mean a product is safe for human consumption or the environment. It indicates that the product meets specific standards and guidelines for its intended use in food processing environments, significantly reducing health risks.
“Food grade” refers to materials and products that are safe for direct contact with food. They comply with specific standards and regulations set by regulatory agencies based on intended use. Examples of food-grade materials include stainless steel, glass, certain plastics, and NSF registered lubricants.
“Food safe” is a broader term that refers to anything that is safe for use with food. It can apply to materials, products, equipment, or processes that have no harmful effects on human health.
While "food grade" specifically refers to materials suitable for food contact, "food safe" can also apply to other aspects, such as food preparation methods, storage conditions, and food processing techniques.
