    Abstract: An overbased calcium sulfonate grease composition comprising a reduced amount of overbased calcium sulfonate, calcium hydroxyapatite, base oil, one or more converting agents, and one or more complexing acids if a complex grease is desired. The calcium sulfonate grease composition improves thickener yield and expected high temperature utility as demonstrated by dropping point. A method of making the composition comprising the steps of mixing the calcium sulfonate and base oil, adding the calcium carbonate either before or after conversion, adding one or more converting agents, and adding one or more complexing acids. All or a portion of one or more of the complexing acids may be added with or prior to the one or more converting agents.

    Abstract: A grease composition for use in resin lubrication wherein at least one amine salt of an unsaturated or saturated fatty acid is incorporated in a grease base material which includes a base oil and a thickener, preferably wherein at least one fatty acid amine salt of the following general formula (1) is incorporated: RCOO−R′NH3′ wherein either (i) R is an unsaturated by hydrocarbon group having from 15 to 21 carbon atoms, and R′ is a saturated or unsaturated linear or branched hydrocarbon group having from 8 to 22 carbon atoms; or (ii) R is a linear saturated hydrocarbon group having from 5 to 21 carbon atoms, and R′ is an unsaturated hydrocarbon group having from 16 to 18 carbon atoms. The grease composition of the- present invention improves the lubricity between resin and resin or resin. and another material such as a metal.
