  • Patent number: 6492317
    Abstract: Hard surface cleaning formulations include an associative thickener and a blend of at least two nonionic surfactants selected from the group consisting of ethoxylated alcohols and ethoxylated fatty acids. The formulations exhibit an advantageously high foam volume of at least about 150 cc when a 100 ml aqueous solution containing about 0.1 wt. % of the formulation is agitated at 2,500 rpm for a cumulative agitation period of about 1200 seconds. The formulations also exhibit satisfactory foam stability sufficient to clean at least about 25 plates (ASTM D4009-92). Preferably, the associative thickener is the reaction product of a C6 or greater epoxide compound with a polyoxyalkylene polyol. The ethoxylated alcohols and ethoxylated fatty acids each most preferably contain C8 to C18 carbon chains which are ethoxylated with between about 3 to about 20 moles of ethylene oxide.

  • Patent number: 6472440
    Abstract: Defoamers are the products of the reaction of epichlorohydrin and compounds having the formula II R3(EO)n(PO)mOH  (II) wherein R3 is an alkyl, alkenyl or arenyl group having from 4 to 22 carbon atoms; a substituted alkyl or alkenyl group having from 4 to 22 carbon atoms wherein; n is a number from 0 to 50 and m is a number from 0 to 10; wherein the mole ratio of epichlorohydrin to (II) is from about 0.60/1 to about 2/1 are extremely efficient defoamers for aqueous surfactant systems. The defoamers are added to a surfactant in an amount sufficient to reduce or eliminate foam and have the advantage of being totally dispersible in water, are readily biodegradable, contain no organic solvents and do not affect the detergency of surfactants with which they are used because they are nonionic surfactants in themselves.

  • Patent number: 6468957
    Abstract: The invention relates to a neutralization and granulation method wherein a neutralizing foam is used as granulation adjuvant. The neutralizing foam was previously obtained by mixing an anionic surfactant in its acid form, which was expanded using a gaseous medium, and a highly concentrated, aqueous alkaline component, which was expanded using a gaseous medium. The neutralizing foam has an average pore size of less than 10 mm, preferably less than 5 mm and especially less than 2 mm.
