Potassium isomerized linoleate satisfies EPA MB-35-00 for surface disinfection of Candida auris (AR-0381)

Abstract

Four distinct lots of Potassium Isomerized Linoleate, 442 mM or 141 mg/ml (within the cosmetic-cleanser and commercial-soap acceptable concentration ranges but much greater than physiologic conditions), showed greater than 5 log kill rates (total) for Candida auris (AR-0381) for all carriers during 5 separate procedural runs of EPA MB-35-00. After exposing the inoculated stainless-steel carriers to the plant-oil soap for 1, 2, or 10 minute(s), we recovered no Candida auris on these tested carriers. Control carriers with phosphate-buffered saline applied, recovered 5.0-6.8 Log of colony-forming units per carrier.
