Colloidal products are described which contain an element selected from sulphur, phosphorus and possibly boron, as well as an element chosen from metal alkalis, alkaline earth metals and zinc, micellized in at least one detergent agent. They can be obtained in micelle form by reaction of at least one mineral acid or organic acid, containing sulphur and/or phosphorus and possibly an acid containing boron, these acids being directly introduced or formed in situ with at least one basic derivative containing a alkali metal and/or an alkaline earth metal and/or zinc, in the presence of at least one surface active agent. The colloidal products can be used as wear resistance and extreme pressure additives for lubricants.
