Description

The present invention relates to the cleaning of textiles, as well as the provision of liquid compositions for this purpose.

Usually, liquid detergents are provided in a sufficient amount for several wash loads in storage containers. To carry out a washing process, the consumer removes the necessary for a wash dose liquid detergent from this reservoir. The necessary dose is usually determined by measuring the liquid detergent in a measuring cup and then transferred, for example, in the dosing drawer of a washing machine, or placed together with the measuring cup directly into the washing drum of the washing machine.

To increase the sustainability of the liquid detergent products, a reduction of the CO ₂ balance per wash load (reduction of the packaging volume and material with a constant number of wash loads, reduction of the energy input for transport) is aimed at. This can be done by providing more concentrated liquid detergent compositions. However, the concentration of the liquid detergents leads to a reduction in the emptying, in particular the residual emptiness, the reservoir. Typically, to solve this problem, the packaging specialist recommends using a container with an outlet at the bottom of the booth.

In the publication WO 2007/130562 liquid compact detergents are described, which can be assembled in a squeeze container with outlet on the floor.

When removing the detergent from the container, often the beginning and the end of the removal can not be planned accurately, i.e., they can not be planned accurately. either the detergent runs out of the container too early and is spilled, or the addition is delayed by late completion of the flow, resulting in overdosing. Since, when using concentrates, said time delays in fluidity or said spotting result in greater wastage due to the higher concentration, it was an object of the present invention to combine the container and liquid detergent into a detergent product, which does not have these disadvantages. Another problem with the preparation of liquid detergent concentrates was to ensure optimal emptying.

Compositions which are preferred according to the invention comprise water in an amount of from 0 to 50% by weight, in particular from 5 to 50% by weight, particularly preferably from 5 to 45% by weight, based in each case on the total weight of the composition. It is preferred that the detergent more than 5 wt .-%, preferably more than 15 wt .-% and particularly preferably more than 25 wt .-%, each based on the total amount of detergent, water.

In addition to the compelling components according to the invention, organic solvents can be added to the liquid composition according to the invention. Organic solvents are liquid, dissolve at 20 ° C to at least 1 g in 100 g of distilled water and have at least one covalent bond between carbon and hydrogen in the molecule. It is essential according to the invention, based on the weight of the composition, to use amino-group-free organic solvents in a total amount of from 0 to 10% by weight, in particular from 0 to 7.5% by weight. Suitable amino-free organic solvents include mono- or polyhydric alcohols or glycol ethers, provided that they are miscible with water in the specified concentration range.

The composition according to the invention necessarily has a viscosity of at least 1000 Pas (rotational rheometer, cone plate (40 mm diameter, 2 ° cone angle), 0.5 rpm, 20 ° C.) and a yield point of at least 10 Pa (20 ° C.).

It is preferred according to the invention if the composition has a viscosity of at least 2000 Pa.s, more preferably of at least 3000 Pas.

The yield stress refers to the smallest stress (force per area) above which a plastic substance behaves rheologically like a liquid. It is therefore given in Pascal (Pa). It is preferred according to the invention if the composition has a yield point of at least 20 Pa, more preferably of at least 30 Pa.

The yield point is determined on a shear stress controlled rheometer AR G2 from Texas Instruments at a temperature of 20 ° C with a cone-plate measuring system with 40mm diameter and 2 ° cone angle. The samples were loaded in the rheometer with a time-increasing shear stress s (t). For example, within 10 minutes, the shear stress may range from the lowest possible value (e.g., 2 mPa) to e.g. 10 Pa can be increased. As a function of this shear stress, the deformation γ of the sample is measured. The deformation is plotted against the shear stress in a log-log plot. If the examined sample has a yield point, clearly two areas can be distinguished in this plot. Below a certain shear stress, one finds a purely elastic deformation. The slope of the curve γ (σ) (log-log plot) in this area is one. Above this shear stress, the flow range begins and the slope of the curve is suddenly higher. The shear stress at which the bending of the curve takes place, ie the transition from the elastic to a plastic deformation, marks the yield stress. A convenient determination of the break point is possible by applying tangents to the two curve parts. Samples without yield point do not show a characteristic kink in the function γ (σ).

In addition, the compositions according to the invention may contain further ingredients which further improve the performance and / or aesthetic properties of the detergent. In the context of the present invention, the composition according to the invention preferably additionally contains one or more substances from the group of enzymes, bleaching agents, complexing agents, builders, electrolytes, pH adjusters, perfumes, perfume carriers, fluorescers, dyes, hydrotropes, foam inhibitors, silicone oils, antiredeposition agents, anti-shrinkage agents , Anti-caking agents, color transfer inhibitors, antimicrobial agents, germicides, fungicides, antioxidants, preservatives, corrosion inhibitors, antistatic agents, bittering agents, ironing aids, repellents and impregnating agents, swelling and anti-slip agents, plasticizing components and UV absorbers.

The compositions according to the invention already provide the viscosity profile according to the invention without the use of polymeric thickeners. A polymeric thickener is understood according to the invention to mean a polymeric compound which has an average molecular weight (weight average Mw) of more than 1000 g / mol and which increases the viscosity of the composition according to the invention by at least 500 mPas in an amount of 0.1% by weight ,

As a polymeric thickener according to the invention in particular polyacrylates. The polyacrylates include polyacrylate or polymethacrylate thickeners, such as, for example, the high molecular weight homopolymers of acrylic acid crosslinked with a polyalkenyl polyether, in particular an allyl ether of sucrose, pentaerythritol or propylene (INCI name according to "International Dictionary of Cosmetic Ingredients", The Cosmetic, Toiletry and Fragrance Association (CTFA) ": carbomer), also referred to as carboxyvinyl polymers.

Suitable builders which may be present in the composition according to the invention are in particular silicates, aluminum silicates (in particular zeolites), carbonates, salts of organic di- and polycarboxylic acids and mixtures of these substances.

Organic builders which may be present in the composition according to the invention are, for example, the polycarboxylic acids which can be used in the form of their sodium salts, polycarboxylic acids meaning those carboxylic acids which carry more than one acid function. For example, these are citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, and mixtures of these. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures thereof.

For example, a hole in a container wall is an outlet. For thicker walls, this outlet can also be tubular. The outlet may also be designed in the form of a tube leading to the outside, which extends beyond the dimension of the wall of the container. This tube also forms a filling aid. The tube may for example be a flexible tube (eg made of silicone), which can be compressed when closing the container with a closure.

Lotrecht means that the container is oriented in such a way that the direction of flow of the liquid composition within the part of the cavity of the outlet to be considered points vertically downwards to the ground.

The cross-sectional area of the narrowest point of the flow is a cross section of the outlet cavity having the smallest cross-sectional area which is perpendicular to the vertical direction of flow of the liquid detergent composition through the cavity of the outlet. The perimeter is the perimeter of this cross-sectional area Q (cross-sectional area of the outlet at the narrowest point of the flow).
