Abstract

Detergent with antistatic effect is intended for washing, cleaning and cleaning textile materials made of synthetic fibers and plastic objects, where static electricity can cause a number of undesirable effects. The detergent composition with antistatic activity is based on the synergistic effect and the weight ratio of surfactants, characterized by the formula where = 2 CH, ..I J R- K-(C2H4O)n-H X" (Ó2H4°)m-H R = alkyl with 6 to 22 carbons; n, m = up to 20; X = Cl", Br", CH.jSO4 and the formula R-HHCOCH, XOOCCH, \ X «-CH2-CH2-Hz ^\;h, ,ch2coox COOX where R = alkyl with 6 to 22 carbons: X = alkali metal, e.g. Ka+, ammonium group, monoethanolamine to triethanolamine group or Ir, the weight ratio of their mixture to the other active ingredients of the recipe being 1:0.2 to 100 and the weight ratio of components A:B being 1:1 to 20.

Description

The invention relates to a detergent composition with antistatic activity, in which the combination of substances causing this property is chosen so as not to reduce other useful properties of the detergents.

Most plastic objects and fibers produced to date do not have a permanent antistatic treatment. The formation of static electricity has a number of negative effects. It accelerates dusting and further soiling of objects, and can also have an adverse effect on the user.

Ordinary detergents and cleaning agents do not have antistatic effect. The reduction of static charge is ensured by the action of special antistatic agents applied to the surface after the washing or cleaning process. For these purposes, cationic surfactants alkyltrimethylammonium chloride, dialkyldimethylammonium chloride or alkylimidazoline derivatives are commonly used. These are mostly substances that are liquid, that is, their dry matter is sticky and their residue on the treated surface facilitates refilling despite the antistatic effect they cause. This property is particularly unfavourable in carpet shampoos, where even a relatively small content of cationic surfactants sharply increases the stickiness of the dry matter, against which the composition of the entire formula is aimed by the choice of all basic components, such as, in particular, special alkyl sulfosuccinates and dispersion polymers. For this reason, the issue of antistatic effect in carpet shampoos remains practically unresolved.

The essence of a detergent composition with antistatic activity containing a surfactant with activating capabilities together with other surfactants and optionally activating, softening, filling, fragrance, coloring, disinfectant and biologically active substances or mixtures thereof is that it contains a mixture of surfactants characterized by formula A,

The proposed combination of surfactants has a number of special advantages, among which, first and foremost, is the synergistic effect of substances A and substances characterized by formula g, which allows reducing the content of the antistatic component A itself to a minimum that does not yet cause stickiness and adhesion of the dry matter of the detergent composition, while the antistatic effect is at least as good as if the content of substance A in the formula was at least tenfold.

The substance characterized by formula B is a non-sticky solid in itself and its presence in the formula significantly increases the detergent efficiency of the product. It is therefore not added to the detergent in addition, but can effectively replace some of the substances used so far.

Another advantage of the combination of substances of type A and B is that they can be mixed with anionic surfactants, which achieves a high detergent effect of the entire formula. The combination also brings a fungistatic effect to the product.

For further clarification, examples are given below, which, however, do not limit the scope of the invention in any way.
