The present invention is directed to a lipid-based ophthalmic emulsion. The emulsion has an increased amount of a mucoadhesive galactomannan polymer that promotes a long-lasting protection against desiccation and moisture retention.

A method for preparing a non-hydrogenated, non-palm emulsifier composition, comprises the steps of:providing a fatty acid composition comprising at least 80% by weight free fatty acids, andreacting the fatty acid composition with glycerol, wherein the emulsifier composition comprises: at least 20% by weight monoglycerides; less than 60% by weight of diglycerides; and and from 0-80% by weight triglycerides, wherein the weight % is with respect to the total of monoglycerides, diglycerides and triglycerides, and wherein the fatty acid residues bound to the monoglycerides, diglycerides and triglycerides in the emulsifier composition comprise: from 5% to 80% by weight stearic acid (C18:0); from 10% to 80% by weight oleic acid (C18:1); and from 1% to 10% by weight palmitic acid (C16:0), based on the total weight of C8 to C24 fatty acids.

The present invention is directed to a lipid-based ophthalmic emulsion. The emulsion has an increased amount of a mucoadhesive galactomannan polymer that promotes a long-lasting protection against desiccation and moisture retention.

An embodiment of a CBD Nano-Emulsion material and process comprises a formulation comprising at least a lecithin or mixed lecithin, one or more carrier oils, and a Vitamin E TPGS from a sunflower version and a soy version. Among either version, the versions may further comprise mixed tocopherols, and still further comprise at least one of; an LCT oil, an olive oil, and a coconut oil. Any one of the versions may further comprise at least one of; sodium benzoate, potassium sorbate, and sorbic acid; and even yet further comprise purified water. Some embodiments may comprise a Vitamin E acetate.

The use of surfactant formulations comprising long-chain alcohols as additives in aqueous polymer dispersions for production of porous polymer coatings, preferably for production of porous polyurethane coatings, is described.

A method of making an invert oil-based mud (OBM), a composition for an invert OBM, and a method of using an invert OBM are provided. The invert OBM includes an oil-based fluid, an emulsifier comprising a calcium salt of an alkyl esterified fatty acids from a vegetable oil, an emulsion activating agent, and a water-based fluid.

The present subject matter illustrates a method for accelerated in-situ chemical reduction of subsoil matter. The method comprises supplying a mixture comprising ferrous sulfide into soil pathways to biologically react with dissolved contaminates in the groundwater. Further, an organic hydrogen donor is supplied into the soil-pathways to produce anerobic-conditions to cause indigenous anaerobic bacteria to biodegrade residual concentrations of the contaminates.

The present invention relates to a dispersant derived from anhydride functionalized polyester derived from carboxylic acid functionalized polyester. The anhydride functionalized polyester is then reacted with a multi-amine species forming amide and salt bonds. The technology allows lower reaction temperatures when the multi-amine species is present. The lower reaction temperature allows the use of a broader selection of polyester repeat units.

Low concentration surfactant emulsions and methods of making and using the same are disclosed herein. The emulsions have the benefit of employing less surfactant than conventional emulsions. Further, the emulsions are dilutable and retain their stability upon dilution. A benefit of the emulsions is that they leave a low residue, preferably no residue, on a surface after contact.
