Comprehensive Overview

Toilet soaps, laundry soaps, liquid hand washes, dishwashing liquids, and detergent powders are evaluated based on cleansing efficiency, mildness, and total active ingredient concentration. We test Total Fatty Matter (TFM %) for soap grade classification (Grade 1, 2, 3 under IS 2888), free caustic alkali, active detergent matter, and phosphates.
