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). Detergent formulations, such as laundry detergents, softeners, and other materials, containing any of these materials are disclosed. Laundry methods employing these formulations are also disclosed. These formulations are useful as laundry detergents and can be biodegradable, heavy duty liquids, 2X or 3X and up to 6X concentrates, low foaming, and/or effective in a high efficiency wash-ing machine. Methods for laundering fabrics with the compositions are also disclosed.
L'invention porte sur des sulfo-estolides et sur leurs procédés de fabrication. Des procédés utiles comprennent le blanchiment côté acide, l'hydrogénation partielle de l'acide gras, le prétraitement de l'acide gras pour fournir une inhibition de la couleur, l'hydrolyse côté acide des sulfo-estolides ou la conversion de SHP en un produit sensiblement totalement hydrolysé (HSHP) ou un produit partiellement hydrolysé (PHSHP). L'invention porte également sur des formulations détergentes, telles que des détergents pour lessive, des assouplissants et autres matières contenant n'importe laquelle de ces matières. L'invention porte aussi sur des procédés de blanchissage employant ces formulations. Ces formulations sont utiles comme détergents pour lessive et peuvent être des liquides à usage industriel, biodégradables, des concentrés 2X ou 3X et jusqu'à 6X, à faible moussage et/ou efficaces dans une machine à laver à haut rendement. L'invention porte enfin sur des procédés de blanchissage de tissus par les compositions.
