Title (DE) FETTALKOHOL(ETHER)SULFATE MIT VERBESSERTEM KÄLTEVERHALTEN
(EN) FATTY ALCOHOL (ETHER) SULPHATES WITH IMPROVED LOW-TEMPERATURE BEHAVIOUR
(FR) SULFATES (D'ETHER) D'ALCOOL GRAS A COMPORTEMENT A FROID AMELIORE
Abstract:
(DE) Es werden neue Fettalkohol(ether)sulfate vorgeschlagen, die man erhält, indem man Mischungen von (a) Fettalkoholen mit 6 bis 22 Kohlenstoffatomen und (b) Fettalkoholethoxylaten mit 6 bis 22 Kohlenstoffatomen und 1,9 bis 3,9 Ethylenoxideinheiten im Gewichtsverhältnis 20:80 bis 80:20 in an sich bekannter Weise cosulfatiert und anschließend mit wäßrigen Basen neutralisiert. Die Stoffe weisen gegenüber Ethersulfaten mit vergleichbaren Ethoxylierungsgraden ein deutlich besseres Kälteverhalten auf.
(EN) The invention relates to novel fatty alcohol (ether) sulphates which are obtained in that mixtures of (a) fatty alcohols with 6 to 22 carbon atoms and (b) fatty alcohol ethoxylates with 6 to 22 carbon atoms and 1.9 to 3.9 ethylene oxide units in a ratio 20:80 to 80:20 by weight are sulphated in a manner known per se. Said mixtures are subsequently neutralised with aqueous bases. In comparison with ether sulphates with comparable ethoxylation levels the low-temperature behaviour of the substances is clearly improved.
(FR) L'invention concerne de nouveaux sulfates (d'éther) d'alcool gras obtenus par cosulfatation de manière connue en soi de mélanges (a) d'alcools gras ayant entre 6 et 22 atomes de carbone et (b) d'éthoxylates d'alcool gras ayant entre 6 et 22 atomes de carbone et entre 1,9 et 3,9 unités d'oxyde d'éthylène dans un rapport en poids de 20: 80 à 80: 20, et par neutralisation avec des bases aqueuses. Comparativement aux sulfates d'éther à niveaux d'éthoxylation comparables, ces substances présentent un comportement à froid nettement meilleur.
