CS252305B1 - Detergent for wool washing - Google Patents

Abstract

The solution concerns special detergents intended for washing wool. The essence of powder and liquid detergent for washing wool is, in addition to common raw materials, the use of 3 to 30% by weight. A combination of alkylamidobetaine and alkylalkoxylated quaternary ammonium salt, while the combination is composed of 5 to 80% by weight. alkylamidobetaine and 20 to 95% by weight. alkylalkoxylated quaternary ammonium salt, which ensures a gentle effect on wool. The main advantages of powder and liquid detergent intended for washing wool are that it allows trouble-free maintenance of woolen textiles and has a dermatologically favorable effect.

Description

The invention relates to laundry detergents for washing wool.

Woolen fabric is one of the most delicate textile materials in terms of washing maintenance due to the composition and structure of the woolen fiber. Wool washing is accompanied by deterioration in which a number of physicochemical factors are involved. The consequence of their interaction is especially irreversible clotting and felt fabric of washed textiles. These undesirable effects are particularly noticeable when using conventional detergents and while maintaining gentle conditions, i.e. low mechanical action temperatures.

Weakening of these negative effects is achieved by the application of special detergents, which are characterized by a special composition of the surfactant part of the recipe and the presence of plasticizers. The most commonly used substances include ampholytic surfactants based on imidazoline, cationic surfactants (Japan PV 5056197), salts of partial phosphoric acid esters (UK 1515792), soluble zirconium salts (Switzerland 488800).

The more dimensional stability of woolen fabrics, especially after multiple washes, has been made possible by the invention of a powder and liquid detergent for washing wool comprised of surfactants, complexing, filling, fragrance and auxiliary agents, which is based on the fact that 30% wt. a combination of alkylamidobetaine and alkylalkoxylated with quaternary ammonium salts, wherein the combination is comprised of 5 to 80 wt. % dimethylcarboxymethyl-propylamidoammoniumbeteine fatty acids (Cg to ΰ ^ ₂ ) and 20 to 95 wt. di- to oktadekaetoxyálkylamoniummethosulfétu fatty acids, C 22 to ^C _g *

The main advantages of powdered and liquid wool scouring agents are that they allow the woolen fabrics to be washed without difficulty, and another advantage is the dermatologically beneficial effect achieved by the presence of alkylamidobetaine and branched olefins.
