Influences of some Adjuvants on Lethal Activity of Ultraviolet (254nm) Radiation

Abstract

The lethal efficacy of UV 254nrn radiation has been assessed against a common microbial organism in the presence of a wide variety of chemical compounds which by themselves are either antimicrobiologically inert (Polysorhate-80), mildly active (chloroquine phosphate) or distinctly active (phenol and chlorocresol). Irrespective of their antimicrobial status, every one of the adjuvants adversely affected the lethal efficacy of UV radiation. The underlying cause was found to be due principally to absorption.
