Food grade additives for chain oils

Types of food contact lubricants

The United States Department of Agriculture (USDA) has created 3 original food-grade classifications which are still used, today.

• H1 lubricants (finished lubricants) are used in food processing environments where there is the possibility of incidental food contact. They differ from edible food or food ingredients

• HX-1 lubricants are ingredients used in the formulation of H1 lubricants

• H2 lubricants are used on equipment and machine parts where there is no possibility of contact with food

• H3 lubricants are typically edible oils, used to prevent rust on hooks, trolleys and similar equipment, and where there will be direct food contact.

We have a range of high-performance Priolube™ ester base fluids and lubricity additives which are suitable for use as HX-1 ingredients. 

Additives for incidental food contact lubricants

Our food grade chain oil esters are highly versatile and can provide special performance benefits: 

• They allow for formulation of lubricants in the viscosity range 68 – 220 mm²/s
• They are safe for use in food operations
• They provide high oxidative stability
• They have low volatility below 230°C
• They leave low deposits upon decomposition
• They provide excellent lubricity.

Our synthetic esters help to deliver improved productivity through reduced downtime for equipment repairs, lower maintenance costs and prolonged equipment lifetime. 

We also have a wide range of water soluble and insoluble polyalkylene glycols (PAGs), which are particularly suited as carriers for solid lubricants in high temperature applications such as ovens. 

At elevated temperatures (>600°C), PAGs will evaporate cleanly, without the formation of harmful residues.
