Colloidal products containing calcium and/or magnesium plus sulfur and nitrogen are obtained by at least partial neutralization of the basicity reserve of at least one overbasic sulfonate charged with calcium carbonate and/or with magnesium carbonate dispersed within micelles. The neutralization is by means of at least one functional dicarboxylic acid of the formula: <IMAGE> where each symbol a is a whole number from 1 to 8, x and z are each a number from 1 to 4, y is a whole number from 0 to 4 and n is 1 or 2.
