Abstract
Official abstract text for this publication.
A grease composition is disclosed, having from 75 to 85 weight percent of a lubricating base oil, from 15 to 25 weight percent of a thickener component including one or more of (i) one or more natural oil derivatives comprising octadecanedioic acid dimethyl esters, (ii) one or more carboxylic acids and/or derivatives thereof, comprising 12-hydroxystearic acid, and (iii) one or more of a metal base compound comprising lithium hydroxide, and from 1 to 15 weight percent of one or more optional additives. Processes for making grease compositions are also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A grease composition comprising: (a) about 75 to 85 weight percent of a lubricating base oil comprising a polyalphaolefin base oil, and (b) about 15 to 25 weight percent of a thickener component comprising dimethyl 1,18-octadecanedioate and lithium hydroxide. 2. The grease composition of claim 1 , wherein the lubricating base oil comprises a mineral oil, a synthetic oil, a natural oil, or a natural oil derivative, individually or in combinations thereof. 3. The grease composition of claim 2 , wherein the lubricating base oil comprises a polyalphaolefin base oil. 4. The grease composition of claim 1 , wherein the thickener component further comprises 12-hydroxystearic acid and or ester derivatives thereof. 5. The grease composition of claim 4 , wherein the thickener component comprises 12-hydroxystearate esters.
