The subject invention provides biological emulsifying agents for use in formulating metalworking fluids, methods for formulating the metalworking fluids, and enhanced metalworking fluids.

Provided are an emulsifier derived from sugar polymer capable of successfully emulsifying even unsaturated oil, a production method therefore, and a production method for emulsion using the emulsifier. This emulsifier can be obtained by a production method including an emulsification improving step of improving the emulsification of sugar polymer particles dispersed in water. In this emulsification improving step, the emulsification of sugar polymer particles can be improved by an action of an emulsification aid that is at least water-soluble one kind selected from salts, an amphiphilic agent, saccharides, an organic acid, and an amino acid. Alternatively, the emulsification of sugar polymer particles can be improved by storing the sugar polymer particles dispersed in water at a low temperature of 10 C. or lower.

The present invention relates to esterified glycerylated alkyl glycoside and to a process for making same. The esterified glycerylated alkyl glycoside have one or more polyglyceryl moieties and one or more acyl moieties, wherein all of the one or more acyl moieties are situated on the one or more polyglyceryl moieties via an ester linkage. These compounds have been found to be useful as emulsifiers and coemulsifiers in the formulation of a phase stable emulsions suitable for use in personal care, home care, industrial and institutional, and health care applications.

A process is described by which the solid waste of grape resulting from processes such as vinification, is treated with hot steam, then is treated with alcoholic solutions, the alcohol being removed, then the oil residues present in the solid residue are removed. The said solid residue is then subjected to aqueous extractions, the aqueous medium is separated from the remaining solids, and this aqueous medium is concentrated. The said material is also described, being capable of emulsifying oil-in-water emulsions and provide stability to colloids.

This invention relates to stabilizer concentrates which improve the stability of mono- and/or diesters of mono- and/or diethylene glycol wax dispersions in personal care compositions, wherein the stabilizer concentrates comprising hydrogenated castor oil and betaines and are free of anionic surfactants.

A method for producing water-soluble or water-dispersible microparticles, which includes preparing a solution or dispersion that contains a protein and an anionic polysaccharide and that has a pH higher than the isoelectric point of the protein, and mixing the solution or dispersion to set the pH of the solution or dispersion to a value closer to the isoelectric point.
