Title
(EN) PREPARATION METHOD FOR ESTERQUATS BASED ON OIL
(FR) PROCÉDÉ DE PRÉPARATION D'ESTERQUATS À BASE D'HUILE
Abstract
(EN)
The present invention relates to a process for producing an esterquat by a transesterification reaction of a fatty acid oil or a mixture comprising one or more fatty acid oils and one or more fatty acids with a tertiary hydroxy amine and then a quaternization reaction. Esterquats obtained by the method of the invention show beneficial properties in particular when used as active component in fabric softener materials.
(FR)
La présente invention concerne un procédé de production d'un esterquat par une réaction de transestérification d'une huile d'acides gras ou d'un mélange comprenant une ou plusieurs huiles d'acides gras et un ou plusieurs acides gras avec une hydroxy amine tertiaire suivie d'une réaction de quaternisation. Les esterquats obtenus par le procédé de l'invention présentent des propriétés bénéfiques en particulier lorsqu'ils sont utilisés en tant que composant actif dans des matières adoucissantes pour tissus.
