Lipase for Grease Removal: Choosing and Testing a Cleaning Enzyme

Detergent lipase is a candidate for soils containing hydrolysable fats such as triglycerides. It is not a universal solvent for every material described as grease, so identify the soil and compare performance in the actual cleaning formulation.

Identify what the grease contains

Food oils, body soils and industrial lubricants differ chemically. A lipase reaction relies on suitable ester bonds; performance on a triglyceride-rich food soil does not establish performance on a mineral-oil lubricant. Record the soil composition and ageing history before interpreting a trial.

Why formulation and contact matter

Lipase acts at an oil–water interface, and access to that interface depends on how the soil is dispersed and presented. Cleaning also requires released material to leave the surface and remain dispersed. Test lipase with the intended surfactant system, agitation and rinse rather than in water alone.

Use a grade intended for cleaning

The enzyme identity does not establish stability in a detergent concentrate. Scientific & Technical offers a detergent lipase and a mixed detergent enzyme blend as candidates. Choose the product format around formulation compatibility and the way it will be handled and dosed.

Look beyond a visually improved stain

Assess residual grease, odour and redeposition after washing and drying. Match the wash liquor ratio and mechanical action between treatments. If the enzyme helps only at an unrealistic contact time, the result may not translate to the intended product.

Frequently asked questions

Will lipase remove engine oil?

That cannot be assumed. Many lubricants contain components outside the main substrate range of triglyceride lipase.

Does adding lipase always reduce surfactant demand?

Only a controlled formulation comparison can establish that while maintaining the required cleaning performance.

Troubleshooting

• Food grease responds but industrial oil does not: check whether the second soil contains suitable ester substrates.
• Grease is released but redeposits: review surfactant, rinse and suspension performance.

Evidence and scope

These are proposed development comparisons, not validated production recipes or guaranteed performance results. Use current grade-specific technical data for the starting dose and operating conditions. Record the enzyme lot and assay definition, and confirm performance in the finished process before scale-up.
