When sourcing super-cleaning laundry powder, prioritize formulas containing active matter (surfactants) levels of at least 15% to 25% for professional grade cleaning. Look for the inclusion of multi-enzyme systems (protease, amylase, lipase) which are essential for breaking down organic stains. Additionally, ensure the product features optical brighteners for fabric vibrancy and zeolites or sodium tripolyphosphate (STPP) for water softening, though STPP must be checked against local environmental regulations regarding phosphates.
