Description

"Verdickter Weichspüler"  "Thickened fabric conditioner"
Die Erfindung betrifft einen verdickten Weichspüler. Die Erfindung betrifft auch die Verwendung des Weichspülers sowie ein Verfahren zu seiner Herstellung. The invention relates to a thickened fabric softener. The invention also relates to the use of the fabric softener and to a method for its production.
Weichspüler werden der Wäsche im letzten Spülgang der Maschinenwäsche zugesetzt, um den bei trocknender Wäsche auftretenden Effekt der„Trockenstarre" zu unterbinden. Die Trockenstarre hat ihre Ursache in der Ausbildung von Wasserstoffbrückenbindungen zwischen den Fabric softeners are added to the laundry in the last rinse of the machine wash in order to prevent the effect of "dry drying" which occurs during drying laundry
Cellu losefasern. Die kationischen Tenside des Weichspülers dringen in die Faser ein bzw. legen sich auf die Faseroberfläche, verbinden sich mit den negativen Ladungen und schwächen so die Wechselwirkungen. Durch die so verminderte Steifheit des Wäschestücks vermindert sich der Kraftaufwand beim Bügeln und der Tragekomfort wird erhöht. Cellu loose fibers. The cationic surfactants of the softener penetrate into the fiber or lie on the fiber surface, combine with the negative charges and weaken the interactions. Due to the reduced stiffness of the garment, the force required for ironing is reduced and the wearing comfort is increased.
Flüssige Weichspüler werden in zwei Typen unterteilt:„normale" Weichspüler mit einem Gehalt von 1 bis 5 Gew.-% an weichmachenden Verbindungen und„konzentrierte" Weichspüler mit einem Gehalt von 5 bis 80 Gew.-% an weichmachenden Verbindungen. Liquid fabric softeners are divided into two types: "normal" fabric softeners containing from 1 to 5% by weight of softening compounds and "concentrated" fabric softeners containing from 5 to 80% by weight of softening compounds.
Die Akzeptanz eines Weichspüler-Produkts durch die Anwender wird neben der eigentlichen Leistung auch stark von der Viskosität des Produkts bestimmt, wobei mittlere bis hohe Viskositäten von den Anwendern bevorzugt werden. Für normale Weichspüler werden Viskositäten im Bereich von 100 bis 500 mPas (bestimmt mit einem Brookfield-Viskosimeter RV DV II + P; Spindel 2 bei 20 rpm und 20 °C) angestrebt. The acceptance of a fabric softener product by the users is determined not only by the actual performance but also strongly by the viscosity of the product, with medium to high viscosities preferred by the users. For normal fabric softeners, viscosities in the range of 100 to 500 mPas (determined using a Brookfield viscometer RV DV II + P, spindle 2 at 20 rpm and 20 ° C.) are aimed for.
Insbesondere bei normalen Weichspülern ist nach der Herstellung die Viskosität oft zu niedrig und es werden den Produkten Verdicker zur Erhöhung der Viskosität zugesetzt. In der EP 0763592 A1 wird beispielsweise die Verwendung von Fettsäuren, insbesondere von ungesättigten Fettsäuren, als Verdicker in Weichspülern beschrieben. Especially with normal fabric softeners, the viscosity is often too low after preparation and thickeners are added to the products to increase the viscosity. For example, EP 0 763592 A1 describes the use of fatty acids, in particular of unsaturated fatty acids, as thickeners in fabric softeners.
Allerdings besteht weiterhin ein Bedarf an möglichst effektiven und preiswerten Verdickungsmitteln für normale Weichspüler. Eine Aufgabe dieser Erfindung war daher, die Bereitstellung eines verdickten Weichspülers mit 1 bis 5 Gew.-% weichmachender Verbindung, der preiswert herzustellen ist. However, there is still a need for most effective and inexpensive thickening agents for normal fabric softeners. It was therefore an object of this invention to provide a thickened fabric softener with 1 to 5% by weight softening compound which is inexpensive to produce.

Es hat sich überraschenderweise gezeigt, dass der Einsatz eines der genannten, gesättigten d6- Fettmaterialien bei geringeren Mengen zu höheren Viskositätswerten in normalen Weichspülern führt, als bei Verwendung ungesättigter Fettmaterialien oder von Fettmaterialien mit längeren oder kürzeren Alkylketten. Die Verwendung gesättigter Ci6-Fettmaterialien hat weiterhin den Vorteil, dass diese während der Lagerung des Weichspülers, insbesondere nach der ersten Benutzung, nicht zu schlecht riechenden Verbindungen oxidiert werden können. b) a Ci 6 fatty material which is selected from the group comprising palmitic acid, palmitic acid methyl ester, palmitic acid ethyl ester, isopropyl palmitate, hexadecanol, palmitic acid amide, hexadecanal, palmitic acid ethanolamide, palmitic acid propanolamide and mixtures thereof. It has surprisingly been found that the use of one of the mentioned, saturated d 6 - fatty materials at lower levels leads to higher viscosity values in normal fabric softeners, than when using unsaturated fatty materials or fatty materials with longer or shorter alkyl chains. The use of saturated C 6 -Fettmaterialien has the further advantage that it may be oxidized during the storage of the fabric softener, particularly after the first use, not too bad smelling compounds.

Diese Hexadecanol, palmitic acid amide and mixtures thereof. In a particularly preferred embodiment, the fabric softener contains palmitic acid as a thickening agent. These
Verdickungsmittel bewirken bereits in sehr geringen Mengen eine ausreichend hohe Verdickung des Weichspülers und sind somit preiswerte und effektive Verdickungsmittel.

Da das Parfüm auch Einfluss auf die Viskosität nimmt, wurde in allen Weichspülern ein identisches Parfüm eingesetzt.  Since the perfume also influences the viscosity, an identical perfume was used in all softeners.

Die Proben E1 bis E3 waren über mehrere Wochen lagerstabil und zeigten keinerlei unerwünschte Veränderungen. Insbesondere zeigten die Proben E1 bis E3 nur sehr geringe Viskositätsänderungen bzw. -Schwankungen während der Lagerung. Zur Bestimmung der Lagerstabilität wurden die Zusammensetzungen in elektronisch gesteuerten Wärmekammern gelagert. Die Lagerzeit bei 40 °C betrug 4 Wochen und bei 23 °C 12 Wochen. Danach erfolgte eine visuelle und olfaktorische Abmusterung der Zusammensetzungen. Samples E1 to E3 were storage stable for several weeks and showed no undesirable changes. In particular, samples E1 to E3 showed very little Viscosity changes or fluctuations during storage. To determine the storage stability, the compositions were stored in electronically controlled heating chambers. The storage time at 40 ° C was 4 weeks and at 23 ° C for 12 weeks. This was followed by visual and olfactory matching of the compositions.
Die Ergebnisse zeigen deutlich, dass Palmitinsäure bessere Verdickerleistungen zeigt als ungesättigte Fettsäuren (siehe V2) sowie als gesättigte Fettsäuren mit kürzeren (siehe V4) und längeren (siehe V3) Alkylketten. The results clearly show that palmitic acid shows better thickening performance than unsaturated fatty acids (see V2) as well as saturated fatty acids with shorter (see V4) and longer (see V3) alkyl chains.
