Abstract
Overview
ISO 21703:2019 - "Surface active agents - Microbiology - Microbiological test methods for liquid hand dishwashing" - is an ISO standard (first edition 2019) that defines microbiological test methods for liquid hand dishwashing products. The standard specifies procedures for , and for and in liquid hand dishwashing detergents. Key principles include use of non‑selective agar for counts and enrichment culture for presence/absence testing, plus mandatory neutralization of antimicrobial activity in products before analysis.
