Embodiment Construction

[0102] For the preparation of the copolymers of the present invention, the following linear aminosiloxanes are used, which are obtained from the method described in US5486634 by converting the corresponding α,ω-SiH-poly Dimethylsiloxane hydrosilation:

[0103]

[0104] The diepoxy compound used was from DOW Epoxy Systems ( The polypropylene glycol diglycidyl ether of R19) has an epoxy equivalent weight of 329 g / mol and an epoxy value of 171 mg KOH / g.

[0105] Viscosity was measured according to DIN 53019 at 25°C using a Brookfield (type LVT) rotary viscometer.

[0106] Determining the quaternary ammonium nitrogen content of the siloxane:

[0107] Determination of quaternary ammonium nitrogen by potentiometric titration using a dodecyl sulfate solution as titrant with a special solvent-resistant sensor electrode such as the Surfactrode Resistant (Metrohm AG) and a reference electrode (Ag / AgCl bridge double junction , Metrohm AG) composed of electrode combinations.

Abstract

Linear polydimethylsiloxane polyether copolymers having amino and / or quaternary ammonium groups obtainable by the reaction of organopolysiloxanes functionalised with secondary aminoalkyl groups with the reaction products from compounds containing epoxy groups and amines, to the use thereof and to a method for producing same.

Description

technical field [0001] The present invention relates to novel linear polydimethylsiloxane-polyether copolymers having amino and / or quaternary ammonium groups. The invention also relates to these polymers as fabrics, for example woven fabrics, in particular textile woven fabrics, tissue, nonwovens and / or fibers of natural and / or synthetic origin and / or leather, hair or Use of softeners for raw hides and related to their use in cosmetic applications, for example in hair care, skin care and personal hygiene. Background technique [0002] Softeners for fabrics, for example woven fabrics, in particular textile woven fabrics, knitted fabrics, nonwovens and / or fibers of natural and / or synthetic raw materials, are substances which give the material a soft hand. Particularly suitable softeners are polysiloxanes with quaternary ammonium groups. The ionic groups anchor the silicone to the fiber by virtue of electrostatic attraction. In this way friction is reduced and the desired so...
