How to evaluate detergent performance
Foam appearance alone does not measure cleaning power; testing should match real use.
Read article01 / THE IDEA
Powder performance depends on particle distribution, dissolution, moisture and the surfactant system.
Powder is a multi-ingredient system
Laundry powder can combine surfactants, water-hardness control ingredients and flow aids depending on product design. Granule size and distribution affect dissolution and movement through filling equipment. Moisture exposure can cause caking, inconsistent dosing and a poor wash experience. Powder color or fragrance alone cannot demonstrate stain-removal ability.
Test washing and storage together
Run trials on representative stains and textiles while controlling wash cycle, dose, water temperature and hardness. Inspect remaining particles and fabric appearance after the wash. Separately examine powder flow and caking after storage in the intended pack. Removing one laboratory stain does not establish that the powder will work consistently in a machine or on the shelf.
How would this be tested?
For two candidate laundry powders, record granule condition and flow immediately after production. Store packed samples under relevant humidity conditions and inspect for caking. In washing trials, use matched stained textiles at the same detergent dose, cycle and water temperature, checking both stain removal and undissolved residue. If a problem appears, investigate moisture, particle size and powder addition before concluding that the surfactant concentration is too low.
Practical evaluation checklist
01
Monitor flow and caking in storage.
02
Test dissolution across water temperatures.
03
Distinguish lab results from washing-machine performance.
