This article compares HPMC and HEMC for industrial degreasers operating under high-surfactant loads. It explains how cellulose ether selection affects viscosity stability, salt tolerance, surfactant compatibility, anti-settling behavior, vertical cling, thermal resistance, and product processing. HPMC is especially suitable for structured gels and cling-oriented degreasers, while HEMC is often preferred for concentrated, salt-containing, and high-active liquid cleaning formulations. The article also provides a practical testing method, common formulation mistakes, application examples, and guidance for selecting the right cellulose ether based on the complete degreaser formula.
