摘要 |
<p>The invention relates to a composition, comprising: at least one basic alkali metal salt of at least one hydrocarbyl-substituted acidic organic compound, wherein the hydrocarbyl group is derived from a polyalkene having an M &cir& NOt n of at least 600, provided that when the organic compound is a sulfonic acid, the polyalkene has an M &cir& NOt n of at least 900; and provided that when the acidic organic compound is a mixture of acidic organic compounds containing a carboxylic acid and a sulfonic acid which has a hydrocarbyl group derived from a polyalkene having an M &cir& NOt n of less than 900, then the carboxylic acid comprises at least 10 % of the equivalents of the mixture.</p> |
