Foamer HS is a cocamidopropyl hydroxysultaine, and belongs to the class of amphoteric surfactants. It is used in a variety of applications, including formulation of drilling foam bases, foam flooding and gas well unloading. Foamer HS has a low pour point and high flash point, making it an excellent surfactant choice across a broad range of uses. Brine tolerance for this product is excellent. Foams produced with Foamer HS tolerate both condensate and high temperature well. Excellent foam production and half-life are seen in both fresh water and NACE brine. Foam production may be enhanced with the addition of a carefully chosen cosolvent in small quantity. Foamer HS is manufactured with Harcros patented technology.
