Toilet-Cleaner Claims: From Marketing Line to Test Brief
A credible cleaning, environmental or fragrance claim begins with a defined method and acceptance criterion.
Claims such as fast-acting, long-lasting, biodegradable or safer imply different evidence requirements. Define soil, substrate, dose, contact time, water conditions, method and measurement. Ingredient screening does not itself grant a finished-product certification. Write website and label claims after evidence is available.
