TRANS-2112, AMS Powdered Silicone Anti-Foaming Agent

As an antifoaming agent, TRANS-2112 finds utility in biotechnology/fermentation applications, food processing, brewing, pharmaceuticals and water treatment applications. It is especially useful when blended with other powdered or dry products subject to foam formation when the consumer reconstitutes them with water. Examples include: dehydrated soup mixes, instant beverages, powdered detergents and fertilizers. When used in biotechnology applications, TRANS-2112 will not alter microbial growth rates or lower yields. It is compatible in most applications involving ultrafiltration membranes and is non-toxic and autoclavable.
To control foam, the recommended method of application is to add TRANS-2112 directly to the foaming product or process. Pre- diluted aqueous dispersions of TRANS-2112 are not recommended. Each foaming problem is unique and requires different treatment levels of antifoam. Use only the minimum amount of TRANS-2112 required to control the foam. Trial testing will be necessary to optimize the amount of antifoam used in a given process. A good starting point is 0.010% by weight in an industrial aqueous system or fermentation. Food-grade applications are subject to a federally defined legal maximum permissible level of 50 parts per million (ppm) residual TRANS-2112 remaining in the finished foodstuff. In the unlikely event that ultrafiltration membrane fouling should occur, the antifoam can be flushed out and the system cleaned with an appropriate cleaning agent. As with any antifoam or defoamer, thorough testing should always be conducted to determine the suitability and compatibility of the antifoam with the foaming system and processing equipment.
