Neutralizing a surfactant which is comprised of an alkaline-catalyzed reaction product between a monomeric of polymeric alcohol having at least one active hydrogen group and an alkylene oxide with a fatty acid allows the cloud point of the surfactant to be adjusted.
Selon l'invention, la neutralisation d'un agent tensioactif, qui comprend un produit d'une réaction catalysée par un milieu alcalin entre un alcool monomère ou polymère ayant au moins un groupe hydrogène actif et un oxyde d'alkylène ayant un acide gras, permet de régler le point de trouble de l'agent tensioactif.
