Abstract (en)
This invention relates to a detergent-dispersant composition for lubricating or fuel oils, The composition consists essentially of (a) an amount effective as a detergent-dispersant of a hydrotalcite having a specific surface area, determined by the BET method, of up to about 60 m<2>/g and an average secondary particle size of up to about 5 microns, the hydrotalcite particles being untreated or surface-treated with an anionic surface-active agent, and the hydrotalcite being represented by the following formula MgxAl2(OH)6+2x-2y(CO3)y.mH2O wherein x is a positive number represented by 3 < x < 20, y is a positive number represented by 0 < y < 2, and m is a positive number of up to 7, and (b) a hydrophobic dispersant or diluent.
