Description

Powder laundry and cleaning detergent ingredients

FIELD OF THE INVENTION The present invention relates to powdered laundry and cleansing detergent components and methods of making and uses thereof.

Commonly used detergents and detergents contain components that perform a series of functions. The quality of these detergents and detergents depends on the nature, amount and manner of addition and order of ingredients used.

For example, the main components of current textile detergents are, in particular, surfactants, bleaches, cleaning alkalis and builders. Thus, the main components of detergents and dishwashing agents are mainly builders, bleaches, alkalis, dispersants and enzymes.

The ideal builder of textile detergents has a series of actions that soften water. In addition, the builder must be good at transporting liquid components and adequately buffer the tax solution.

The builders used here are mainly crystalline silicates such as sodium tripolyphosphate (NaTPP), zeolites A and P, and Na ₂ Si ₂ O ₅ called SKS-6.

The aforementioned builders can be used to soften the water in several ways (removal or binding of calcium and / or magnesium ions that cause the water to cure). For example, sodium tripolyphosphate dissolves with calcium ions and magnesium ions to form soluble complexes that do not interfere with the cleaning action.

On the other hand, zeolite and filamentous silicate react with calcium ions and magnesium ions to form insoluble complexes. Zeolites produce quite a lot of these insoluble complexes. These particles, which are present in solid form in the liquor, must be suspended with additional detergent ingredients to prevent them from sticking to the fibers. This also applies to other (solid) contaminants and precipitation components that cure water.

Automatic dishwashing detergents also consist of components that can suspend dissolved contaminants and prevent the contaminants from sticking back to the dishes.

Suitable additive detergent components are cobuilders, also called polyelectrolyte compounds. These include homopolymers and copolymers of citric acid, nitrilotriacetic acid, acrylic acid, polyaspartic acid, and starch oxidation products. The above ingredients can also be used in detergents and dishwashing agents.

Of particular interest are polycarboxylates used as polymers having a molecular weight of about 2,000 to 100,000. It consists of various carboxylates and corresponding monomers. In pulverulent fiber detergents and dishwashing agents, polycarboxylates are mainly used in the form of natural sodium salts as solids or aqueous solutions.

In conventional fiber detergents, the amount of builders is 10 to 40% by weight and the amount of auxiliary builders is 1 to 10% by weight based on the total amount of powdery fiber detergent. In the case of cleaners and dishwashers, the amount added is proportional to the grade.

Powdered fiber detergents comprising crystalline silicate as builders should contain less auxiliary builders than fiber detergents containing zeolite A. However, because zeolite A is insoluble, it cannot be used in dishwashing agents and soluble ingredients are suitable for dishwashing agents.

The quality and mode of operation of builders / assistant builders in textile detergents can be measured by secondary washability. Secondary washability particularly indicates the extent to which the builder / assistant builder system can prevent deposits of contaminants on the fibers. To measure secondary washability, the laundry fibers are incinerated and the quantity of ash is measured with a hydrometer.

In the case of dishwashing agents, the mode of action of the builder / assistant builder system is to visually grade the recontamination of the dishes.

In a conventional method, sodium polycarboxylate is added in the form of an aqueous solution or powder when producing detergent powder. Aqueous solutions are sprayed onto other solid detergent components for flowability of the powder product. A particularly good absorbent component is the foliar silicate SKS-6 manufactured by Hoechst AG, Frankfurt am Main, which improves the fluidity of the detergent powder.

Although the washing performance of pure powder mixtures mixed with sodium salts of SKS-6 and polycarboxylates is excellent, the above mentioned builders are not satisfactory mainly in secondary washability with sodium tripolyphosphate and zeolites. Likewise, the use of this mixture as a dishwashing agent has the disadvantage that limestone deposits occur due to the low solubility of SKS-6.

It is therefore an object of the present invention to solve the above mentioned problems and to provide a composition having excellent laundering and cleaning results, particularly with regard to secondary washability.

It is preferable to include 2 to 50% by weight of the copolymer consisting of 0 to 10% by weight of other monomers which is 70%.
