Abstract

The invention relates to improved Weichspueler for textile Flaechenfasergebilde, which are prepared by the addition of certain sulfobetaines in known as Weichspueler mixtures of quaternary ammonium salts and excipients in a concentration of 0.05-10%, preferably from 0.1 to 5%. Suitable sulfobetaines are represented by the general formulas in which R1, R2 and R3 are identical or different alkyl groups having 1-25 C atoms and / or 1-12 oxethylene units and / or, in the R1 and R2 alkyl groups having 1-3 C atoms and R 3 is an alkyl group having 1-25 C atoms and / or oxethylene units and / or, in the R 1 and R 2 are identical or different alkyl groups having 1-25 C atoms and / or 1-12 oxethylene units, where the alkyl groups are also present via NH- CO groups can be attached to the central nitrogen, represent, characterized. The mixtures according to the invention give the textiles improved soft feel and improve the antistatic equipment as well as the absorbency. formulas

Description

Imidazolinium derivatives have become known (J. Amer. Oil Chemists Soc. 55 [1978] 118-121.) Triethanolaminostearatmethasulfat is in mixture with certain excipients as active ingredient for softener (DD-PS 159263).

Although the first two types of active ingredient not only have a good soft-grip effect but also antistatic properties, but have disadvantages in the form of low water dispersibility or solubility and limited cold dissolving power.

Triethanolaminostearate methasulfate has better solubility and dispersibility, but causes only moderate soft-grip effects and hardly any antistatic effect.

In addition to fragrances, nonionic surfactants based on ethylene oxide, glycols and salts of fatty amine with 14-22 C atoms and their oxyethylation products have become particularly well known as additives. These substances result in a better distribution of the active ingredients, but hardly any improvement in the fabric softening effect. They often only represent an additional expense without significant effect.

The absorbency of treated textiles is generally to be criticized, which means that the wearing properties of the textiles are significantly reduced.

Object of the invention

The object of the invention is to improve the properties of fabric softeners and fabric softening concentrates with regard to effective distribution in the concentrated solution as well as in the ready-to-use liquor and to increase the effectiveness with respect to softness, antistatic effects and fiber absorbency.

Explanation of the essence of the invention

The invention has the object of finding chemically readily available additional active ingredients as components for improving the fabric softening effect and to develop appropriate efficacy improved fabric softener on this basis. According to the invention, this object is achieved in that to known per se drug or active ingredient mixtures on the basis of quaternary ammonium salts with conventional additives 0.05-10Ma .-%, preferably 0.1-5 Ma .-%, sulfobetaines of general formulas I, II and III

in which R ₁ and R _{2 are} identical or different alkyl groups having 1-25 C atoms, in which also a CO-NH group may be present as a functional group, or 1-12 represent oxethylene units, are added.

The addition of the sulfobetaines causes a greatly improved homogenization even in concentrated fabric softener solutions.

As a result, a significantly improved cold and hot water solubility and an improved distribution of active ingredients in the application is given.

Furthermore, the textiles treated with the fabric softeners improved according to the invention have significantly improved antistatic properties, increased absorbency of the fibers and an outstanding softening effect.

The addition according to the invention of the sulfobetaines also makes it possible to produce highly concentrated textile finishing agents which can be diluted as desired with cold water.

embodiment

example 1

Preparation of the Weichspülkonzentrate The preparation of the fabric softener is done by mixing the components at 20 to 100 ⁰ C, preferably at 30 to 80 ° C, which requires a time of 10 to 60 minutes, depending on the technology for the mixture. Thereafter, it is perfumed at room temperature. Main recipe components are quaternary ammonium compounds, nonionic surfactants, solubilizers, sulfobetaines, dyes and perfumes.

According to this method, formulations were prepared according to the invention and corresponding comparative samples were omitted, omitting sulfobetaines.
