  • Patent number: 5391788
    Abstract: The present inventions provides a process for preparing a C.sub.14 -C.sub.22 fatty acid alkaline earth metal salt product which is essentially free of C.sub.14 -C.sub.22 fatty acid or C.sub.14 -C.sub.22 fatty acid glyceride. The glyceride content of C.sub.14 -C.sub.22 fatty acid starting material is hydrolyzed with a water-soluble basic compound such as sodium carbonate in the first step of the process. The C.sub.14 -C.sub.22 fatty acid salt aqueous dispersion formed in the first step is converted to an alkaline earth metal salt in a subsequent process step. A biologically active constituent such as methionine hydroxy analog can be incorporated as an additional ingredient during the processing.

  • Patent number: 5389386
    Abstract: The present invention provides a method for controlling fungal disease in cultivated crops. The aqueous fungicide formulation which is applied to pre-harvest and post-harvest crops contains ingredients which are biocompatible for purposes of agricultural and horticultural applications. Illustrative of a formulation which is harmless to animals and humans is an aqueous solution having a content of potassium bicarbonate, potassium carbonate, nonionic surfactant and xanthan gum. The combination of nonionic surfactant and xanthan gum functions as an effective spreader-sticker medium for forming a film-like coating on plant surfaces. The adherent coating exhibits both immediate and long duration fungicidal activities.

  • Patent number: 5382678
    Abstract: This invention provides an improved process for the production of a fatty acid alkaline earth metal salt product which have little or no content or glyceride ingredient. An essential feature of the process is the pre-blending of glyceride-containing fatty acid feedstock and basic alkaline earth metal compound, before mixing with water and heating the mixture to initiate salt-forming and glyceride-hydrolyzing reactions. The fatty acid alkaline earth metal salt product can be recovered in the form of tackless free-flowing dust-free granules.

  • Patent number: 5376300
    Abstract: A powdered laundry detergent composition is provided comprising an active surfactant, at least about 70 wt. % of a water soluble alkaline carbonate salt, e.g., sodium carbonate, about 0.1 to 2 wt. % of a phosphorus-containing sequestering agent, e.g., sodium tripolyphosphate, about 0.1 to 2 wt. % of a polymeric polycarboxylate, e.g., a polyacrylate, and about 1-12 wt. % water.Use of the foregoing detergent composition provides excellent cleaning and whitening of fabrics while avoiding the problem of eutrophication which occurs when a substantial amount of a phosphorus containing builder such as STPP is present in the composition, and while minimizing the problem of fabric encrustation often present when the composition contains a large amount of carbonate builder.
