  • Publication number: 20060241011
    Abstract: A detergent blend stable in strong oxidizing solutions such as sodium hypochlorite or hydrogen peroxide is prepared by admixing together a fluorinated surfactant and an amine oxide or anionic surfactant. This blend can then be formulated into a detergent concentrate which includes a caustic stabilizing compound and possibly other adjuvants to enable the concentrate to be used as is or diluted into a use solution for use. The use solution prepared from the detergent blend is particularly useful in food and beverage production equipment, delivery lines and general hard surfaces such as consumer bathroom, kitchen, floor and general hard surfaces and other applications where strong oxidizing solutions are used for cleaning.

  • Publication number: 20060199757
    Abstract: A detergent blend is prepared by admixing together a fluorinated surfactant and an amphoteric-based sultaine surfactant hydrotrope. This blend can then be formulated into a detergent concentrate which includes a caustic compound, a chelant, a descaler, and other adjuvants to enable the concentrate to be diluted into a use solution for use in either an acid or base environment. The use solution prepared from the detergent blend is particularly useful in cleaning draft beer lines, dairy lines, and other applications where highly concentrated alkaline or acid-based solutions are used for cleaning.
