An alkaline earth alkylaryl sulfonate having a BN of at least 250, wherein the arylnradical is not phenol, wherein the alkyl chain is a linear chain that contains betweenn14 and 40 carbon atoms, and wherein the mole % of the aryl-sulfonate radical fixednon position 1 or 2 of the linear alkyl chain is between 13% and 30%. Such annalkaline earth alkylaryl sulfonate has improved compatibility, solubility, and foamingnperformances while having low color and no skin formation. The starting alkylatenhas a low iodine number, a very high level of monoalkylate, and, as a consequence,na high yield at the sulfonation step. |
