Which Enzymes Do I Need for a Detergent Formulation?

Choose detergent enzymes by the soil you need to remove: protease for protein, amylase for starch, lipase for suitable fats and mannanase for mannan-based residues. Mixed soils can justify a blend, but performance must be measured in the complete formulation.

Define the cleaning job

List the dominant soils, surface or fabric, wash temperature, contact time and water conditions. A laundry formulation and an industrial surface cleaner can require different enzyme balances. Decide how improvement will be measured: stain reflectance, residual soil mass or a validated application-specific endpoint.

Compare a blend with targeted additions

The Scientific & Technical liquid detergent blend lists amylase, cellulase, protease, mannanase and lipase. It is a practical screening candidate for mixed soils. Individual enzymes are useful when one soil class dominates or when you need to identify which component adds value. Confirm compatibility with the intended material, including sensitivity of protein-based fibres to protease.

Separate concentrate stability from wash performance

An enzyme may work when freshly added to a diluted wash and still lose activity during storage in the concentrate. Evaluate both stages. Surfactants, pH, oxidants, preservatives and other ingredients can affect the outcome. Do not assume a successful first-day cleaning test establishes shelf life.

Keep dose denominators explicit

Percentage enzyme concentrate in a finished detergent is different from enzyme concentration in the diluted wash liquor. Record both the formulation inclusion rate and the end-use dilution. This avoids accidentally screening a much stronger wash than the customer will use.

Frequently asked questions

Can an enzyme cleaner replace disinfection?

Soil removal does not by itself demonstrate disinfection. Any antimicrobial claim needs its own validated evidence.

Is one blend best for every stain?

No. Choose against the actual stain panel and formulation, and check that the added components improve the required outcome.

Troubleshooting

• Fresh detergent works but stored detergent does not: investigate concentrate compatibility and retained activity.
• A stain remains after one component is removed: identify the remaining soil before adding more of the same enzyme.

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.
