How to evaluate detergent performance
Foam appearance alone does not measure cleaning power; testing should match real use.
Read article01 / THE IDEA
Liquid laundry development balances stain removal, stability and rinsing.
Different stains require different tests
Greasy stains, particulate soil and food residues behave differently, as do textiles and dyes. Design liquid laundry detergent for its intended wash cycle, dose and user, then test representative stains and fabrics against a benchmark. Assess removal without overlooking textile appearance or remaining detergent after rinsing.
Stability, dose and water
Perfume, salts, temperature and storage can change viscosity or cause separation. Calcium and magnesium may affect some detergent systems. Compare performance across water hardness levels and test actual packaging for accurate dosing, recognizing that automatic washing and handwashing can require different foam behavior.
How would this be tested?
Prepare sets of textiles bearing an oily stain and a particulate soil, then run an identical wash cycle at fixed detergent doses with a benchmark. Record stain removal, fabric appearance and rinsing. Recheck viscosity after storage and dosing from the actual bottle because wash performance is tied to practical dispensing over time. Repeat at relevant water-hardness levels to establish the intended operating range.
Practical evaluation checklist
01
Test varied stain and fabric types.
02
Track viscosity after storage.
03
Balance scent with use and sensitivity requirements.
