  • Patent number: 5503836
    Abstract: A method is provide for controlling the proliferation of molluscs in target habitat by applying to the habitat a compound or mixture of compounds which are fatty acid amides, disubstituted fatty amides, fatty acid alkanolamides and ethoxylated or propoxylated derivatives of amides, alkyl and aryl polyethoxylated or polypropoxylated primary and secondary alcohols, block copolymers of ethylene oxide and propylene oxide, fatty acid substituted alkyl-aminocarboxylic acids, substituted amido and aminosulfates and aminosulfonates, alkylphenoxy polyethoxy ethanols, and ethoxylated tallow diamines. The above compounds are generally classified as surfactants, penetrants, wetting agents, detergents or emulsifiers having either nonionic or amphoteric properties. The performance of these compounds and their mixtures are further defined by their hydrophilic to lipophilic ratio or HLB and by their solubility as defined by their cloud point temperature.
