    • New overbased colloidal products that comprise a core of micellized alkali metal or alkaline-earth metal carbonate, surrounded by a ring of at least one surfactant compound that is selected from among the dihydrocarbyl-dithiophosphoryl-alkane-sulfonic acids, and their salts of alkali metals or alkaline-earth metals are described. They are derived from the carbonation of at least one oxide or hydroxide of an alkali metal or alkaline-earth metal that is carried out within an oily medium that contains hydrocarbon in the presence of at least one dihydrocarbyl-dithiophosphoryl-alkane-sulfonic acid that corresponds to general formula: ##STR1## in which R represents a monovalent aliphatic, cycloaliphatic or aromatic radical that contains 1 to 30 carbon atoms and x has a value of 3 to 6, or an alkali metal or alkaline-earth metal salt of such an acid. These colloidal products can be used as detergent additives notably providing anti-wear and extreme-pressure properties in lubricants. Because of the presence in their molecule of dihydrocarbyl-dithiophosphoric groups, they also exhibit anti-oxidizing properties.

    • Novel (poly)sulfurized carboxylic compounds, their preparation, and their use as additives to lubricating oils are disclosed. Such novel carboxylic compounds are more particularly esters of the general formula:[R.sup.3 --OC(O)--].sub.q R.sup.2 {--C(O)O--(CH.sub.2).sub.m --CH.sub.3-z [--(CH.sub.2).sub.n --S.sub.x --R.sup.1 ].sub.z }.sub.p (1)wherein R.sup.1 is a saturated or unsaturated monovalent aliphatic radical with 1 to 30 carbon atoms; the number x is equal to or greater than 1; z equals 1 or 2; when z equals 1, n is an integer from 0 to 5 and m an integer from 0 to 0.5, with m+n an integer from 1 to 10; when z equals 2, n is an integer from 1 to 5 and m an integer from 0 to 5, with m+n an integer from 1 to 10; R.sup.2 is a hydrocarbon radical with 1 to 31 carbon atoms and a valency of p+q; R.sup.3 is a hydrogen atom or an aliphatic radical with 1 to 30 carbon atoms; p is an integer from 1 to 4; and q is an integer from 0 to 3, with p+q being an integer from 1 to 4. They are obtained by esterifying carboxylic acid R.sup.2 (--COOH).sub.p+q with a (poly)sulfurized monoalcohol:[R.sup.1 --S.sub.x --(CH.sub.2).sub.n --].sub.z CH.sub.3-z --(CH.sub.2).sub.m --OHand possibly an alcohol R.sup.3 OH.
