摘要：
The invention provides a process for preparing a neutral or an overbased detergent, the process by: reacting (a) a pre-prepared suspension comprising (i) a metal base with a mean particle size of 10 micrometres or less; (ii) a surfactant; and (iii) an organic medium in which the metal base is suspended typically by a physical process. An overbased detergent may be formed with a further reaction with acidifying overbasing agent. The invention further provides a lubricant composition containing said neutral and overbased detergent.
