Abstract

A study was conducted of an emulsion plant to find the source of bacterial contamination in the emulsion and to develop a method to control it. An organism similar to the one in the end product was found in a raw material. The growth of the "Proxel1-resistant" organism was controlled by storing the emulsion at 65°C. Combinations of low levels of Squelch2 220 were effective in preserving emulsions A, B, and C. Combinations of Dowicil3 75 and Kathon4 LX were also effective.
