Patent

CA 2397811

The present invention relates to ternary surfactant blends comprising a mixture of at least one cationic surfactant, at least one anionic surfactant and at least one "bridging surfactant" selected from semi-polar nonionic, ethoxylated alkanolamide, and amphoteric/zwitterionic surfactants, and mixtures thereof. More specifically, the invention relates to stable, synergistic mixtures of cationic, anionic, and bridging surfactants that are useful as bulk surfactant blends. Surfactant blends of the present invention are useful for preparing a variety of finished consumer cleaning products, including for example, liquid dish detergents, laundry detergents, automatic dishwasher detergents, hand soaps, laundry bars, personal cleansing bars, multi-purpose cleaners, multi-functional shampoos, body washes, and textile treatment compositions. Surfactant blends of the present invention also may be employed as surfactants in agricultural and pesticide applications. Additionally, the surfactant blends may be utilized in antimicrobial detergent formulations (e.g., antimicrobial hard surface cleaners, hand soaps, shampoos, and dish detergents), soft-terg delivery systems and pre-spotter compositions.

L'invention concerne des mélanges de tensioactifs ternaires comprenant au moins un tensioactif cationique, au moins un tensioactif anionique et au moins un <= tensioactif de pontage >= sélectionnédans les tensioactifs semi-polaires non ioniques, alcynolamides éthoxylés, et amphotériques/zwitterioniques, et des mélanges de ceux-ci. De manière plus spécifique, l'invention concerne des mélanges synergiques stables de tensioactifs cationiques, anioniques et de tensioactifs de pontage, qui sont utiles en tant que mélanges de tensioactifs en vrac. Ces mélanges de tensioactifs conviennent pour la préparation de divers produits de nettoyage finis destinés à la consommation, notamment des détergents de vaisselle liquides, des détergents de lessive, des détergents de lave-vaisselle, des savons pour les mains, des pains de lessive, des pains de toilette, des produits de nettoyage universels, des shampooings multi fonctionnels, des gels douche et des compositions de traitement de textiles. Ces mélanges de tensioactifs conviennent également pour les applications de l'agriculture et des pesticides. Ils peuvent en outre être utilisés dans des formulations détergentes anti-microbiennes (p. ex. nettoyants antimicrobiens pour surfaces dures, savons à main, shampooings et détergents de vaisselle), dans des systèmes vecteurs de détergents doux et dans des compositions de prétraitement des taches.
