Abstract
A lubricant composition includes (a) a hydrocarbon oil including at least 30% wt of isoparaffins, based on the total weight of the hydrocarbon oil, and (b) an alkoxylated natural oil. A method of using the lubricant composition in a water-based composition, in particular a water-based mud, to improve the lubricity and/or to reduce the foaming properties of the water-based composition is also disclosed.
