Plan a trial for your application
Liquid laundry detergents
Using the same formulation, measure cleaning of protein-stained fabric initially and after storage.
Laundry powders
Compare granule blend uniformity and low-temperature cleaning.
Purchase specifications and incoming inspection
Review these properties for the intended application grade. Example figures refer to the cited grade or source. Confirm the offered specification, packaging and lead time in the quotation. Novonesis · Enzymatic laundry powder and protein stains ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Enzyme activity | Units/g by supplier method | Agree for the grade and end use | State the substrate, pH, temperature and reaction time. |
| Activity retention | % | Agree for the grade and end use | Specify the formulation, storage temperature and sample retention interval. |
| Stain removal on test fabric | Change in reflectance | Agree for the grade and end use | Use protein-stained swatches from one batch and a blank control. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
Specify liquid or low-dust granules and sealed packaging. Follow the SDS to minimise dust or aerosol exposure.
Storage and handling
Check transit temperature, remaining shelf life at delivery and batch activity.
Sample and order lead times
Compare quotations by active matter, as-supplied net weight and packaging. State destination and receiving facilities and request MOQ, sample dispatch and commercial arrival dates.
Questions from the plant
Can enzyme activities be converted from their numbers alone?
Compare directly only when method, substrate and unit definition match.
Why does a retained formulation lose activity after a successful fresh trial?
Separate raw enzyme storage from storage in formulation. Test residual activity at the same temperature.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check Enzyme activity, Activity retention, Stain removal on test fabric.
