Sulfo-estolides and methods of making them are described. Useful methods include acid side bleaching, partial hy-drogenation of the fatty acid, pretreatment of the fatty acid to provide color inhibition, acid side hydrolysis of the sulfo-estolides, or conversion of SHP to an essentially fully hydrolyzed product (HSHP) or a partially hydrolyzed product (PHSHP). Formulations and concentrated formulations of automatic dishwasher detergent or machine wash detergent compositions containing ulfo-es-tolides, among others, are also included.
L'invention concerne des sulfo-estolides et leurs procédés de production. Les procédés utiles comprennent : le blanchiment côté acide, l'hydrogénation partielle de l'acide gras, le prétraitement de l'acide gras pour inhiber une couleur, l'hydrolyse côté acide des sulfo-estolides, ou la conversion de SHP en un produit sensiblement totalement hydrolysé (HSHP) ou en un produit partiellement hydrolysé (PHSHP). L'invention concerne également des formulations et des formulations concentrées de détergent pour lave-vaisselle automatique ou des compositions détergentes pour lavage en machine contenant, entre autres, des sulfo-estolides.
