CS252441B1 - Detergent with fabric softener - Google Patents

Abstract

The solution relates to new types of detergents with fabric softening effect, which exhibit antistatic efficiency and improved feel of washed fabrics without the need for additional dosing of special fabric softeners in the washing process. The essence of the detergent with fabric softening effect is the content of 0.7 to 12% by weight of a combination of alkyl alkoxylated quaternary ammonium salt and a mixture of branched olefins with a carbon number of Cg to 890, with a molecular weight of 450 to 1190, while the weight ratio of the components is 0.125 to 40 to 1, preferably 2 to 6 to 1. The main advantages of the detergent with fabric softening effect are that it provides a fabric softening effect simultaneously with the detergent process, thereby simplifying and saving the washing process.

Description

The invention relates to:. Detergents with anti-static effect and improved feel of washed fabrics without additional dosing of special fabric softeners in the washing process.

The fabrics lose their original softness during use, the soft touch and synthetic textile materials acquire a static charge due to the adherence of the garment to the body. This is particularly striking and undesirable in outerwear, which is mainly made of polyester fibers. These undesirable properties increase during washing.

Therefore, special agents, so-called fabric softeners consisting of cationic, ampholytic, non-ionic surfactants, possibly containing deincrustants or mixtures of branched olefins, are applied in the last rinse bath to suppress the build-up of static charge and regain pleasant feel of the fabrics after washing. The maintenance of textiles by washing becomes complicated and expensive by using fabric softeners.

So far, little success in the art is the production of detergents which, in addition to the detergent effect, also provide the fabric softener function. They are characterized by the content of such types of cationic surfactants which do not react with commonly used anionic surfactants to form a precipitate and special oils. However, the softening effect of these detergents is greatly reduced by the necessary subsequent rinsing.

By rinsing more resistant to the formation of an electrically conductive film and the hydrophilization of the fabric surface, the fabric softener principle, it is possible to provide the invention with a fabric softener with antistatic effect and improved feel of washed fabrics based on 0.7 to 12 % wt. a combination of an alkylalkoxylated quaternary ammonium salt and a mixture of branched olefins having a carbon number of Cg to 0 _ο θ, a molecular weight of 450 to 1190, having an average content of 1 to 1.5 double bonds per molecule, the weight ratio of alkylalkoxylated quaternary ammonium salt to the branched olefin mixture 0.125 to 40 to 1, preferably 2 to 6 to 1.

The main advantages of a fabric softener detergent are that it provides a fabric softener effect at the same time as the detergent process, ie without the need for additional dosing of special fabric softeners. This makes the washing process simpler and more economical.

Examples:

1. A detergent composition of 10 wt. % sodium dodecylbenzenesulfonate, 3 wt. sodium soap, 35 wt. % sodium triphosphate, 40 wt. % sodium sulfate, 1 wt. dry weight of water glass, 5 wt. water, 2 wt. % K-cocoamidopropyl-H, N-dimethyl-H-carboxymethylammonium betaine, 0.3 wt. % of perfume, 2.7 wt.% cocospentaethoxymethylammonium methosulfate and 1 wt. mixtures of branched olefins with an average molecular weight of 560. · *

A detergent powder is obtained which provides, in addition to a detergent effect, an antistatic effect.

The performance parameters of the product of Example 1, compared to a foreign detergent of a similar design, comprising 30% triphosphate, 6% sodium alkylbenzenesulfonate, 1.5% oxyethylated fatty. alcohol, 6.5% cationic surfactant, 5% sodium silicate, 24% sodium sulfate, 13% sodium perborate, the rest of the adjuvant and water wt.

- 3 The antistatic effect was evaluated by the amount of surface resistance of the polyester fabric washed in a conventional automatic washing machine, Koncen — 1 trace detergents 5 g.l ·

Washing ability was evaluated by measuring the change in optical remission of a standard soiled polyester fabric washed under the same conditions.

2. In a boiling kettle equipped with a stirrer, a liquid detergent for synthetic fabrics of 10% by weight is prepared. sodium lauryl sulfate, 4 wt.% sulfosuccinate, 5 wt. % alkylamidobetaine, 10 wt. % potassium pyrophosphate, 3 wt. % sodium cumene sulfonate, 0.3 wt. % of perfume, 3 wt.% cocospentaethoxymethylammonium methosulfate, 0.5 wt. mixtures of branched olefins with an average molecular weight of 560 and up to 100 wt. water.

A liquid detergent is obtained which provides a very good anti-static and softening effect with potency values at the level of Example 1.
