Abstract: A water-based lubricating grease composition includes at least 40 wt% water; a salt-based thickener; a polymer-based thickener; and optionally, an inorganic solid- based thickener. A process for preparing the water-based lubricating grease composition may include blending a suitable amount of water with a salt-based thickener to provide a thickened water-based grease, wherein the salt-based thickener is obtained from contacting a base with a fat; and adding a polymer-based thickener to the thickened water-based grease.

Abstract: The present invention provides a water/glycol-based hydraulic fluid that includes a total fatty acid and dimer acid of more than 0.4 and no more than 1.2 mass % as a fatty acid lubricant, and also a phosphate ester at between 0.01 and 0.07 mass %. The phosphate ester has the following structure (1) here R1 and R2 each represent a hydrogen atom or a hydrogen group with a carbon number between 1 and 30, and may either be mutually identical or mutually different; R3 represents a hydrocarbon group with a carbon number between 1 and 20; R4 represents a hydrogen atom or a hydrocarbon group with a carbon number between 1 and 30; and X1, X2, X3, and X4 each indicate an oxygen atom or a sulfur atom, where these may either be mutually identical or mutually different.

Abstract: L'invention concerne une composition lubrifiante aqueuse, comprenant au moins : - de l'eau; - de 0,01 % à 10 % massique d'au moins un polysaccharide; - de 0,1 % à 10 % massique d'au moins une huile de ricin alcoxylée; - de 0,1 % à 10 % massique d'au moins un composé anti-usure soufré et/ou phosphoré. Elle concerne également l'utilisation de la combinaison d'au moins une huile de ricin alcoxylée et d'au moins un composé anti-usure phosphoré et/ou soufré, dans une composition lubrifiante aqueuse comprenant au moins un polysaccharide, pour améliorer ses propriétés anti-usure et/ou extrême-pression.
