Efficient foam control agent, higher thermal and chemical stability, low toxicity, with a low pour point. A viscous liquid at room temperature with a low pour point. It is an efficient foam control agent by having low foam characteristics and inverse water solubility, higher thermal and chemical stability, and low toxicity. It is particularly efficient as low temperature foam control agent for operations running at room temperature. It is used in such processes as fermentation, food processing, potato washing, food washing and pulp and paper processing.
