Description

STABLE, LIQUID DETERGENT WITH RENEWABLE INHIBITION PERFORMANCE

The invention relates to a liquid washing or cleaning agent with a graying-inhibiting polymer.

In order to increase the cleaning performance, washing or cleaning agents are generally added, in addition to the surfactants and builder materials indispensable for the washing process, to further constituents which can be combined under the term "washing assistants." The washing assistants include, for example, foam regulators, soil release polymers, bleaching agents, bleach activators and Other wash auxiliaries are substances which prevent the redeposition of previously separated dirt in a finer distribution (redeposition) .These substances are referred to as graying inhibitors.

Graying inhibitors known in the art are often graying-inhibiting polysaccharides, such as, for example, carboxymethyl cellulose, and in particular

Sodium.

From EP 054325 A1 a detergent with carboxymethyl cellulose known as graying inhibitor.

For some years, liquid detergents or cleaners have increasingly been offered in transparent bottles. Due to the low solubility of carboxymethylcellulose in liquid detergents or cleaners, turbidity occurs when incorporating carboxymethylcellulose into liquid detergents or cleaners. This leads to an aesthetically unappealing product, especially if it is offered in a transparent bottle.

Another problem is that stable dispersions of graying-inhibiting polymers, especially graying-inhibiting polysaccharides, in the matrix of a liquid detergent or cleaning agent are very difficult to obtain.

Accordingly, it was an object of the present invention, a liquid washing or

To provide cleaning agent with a graying-inhibiting polymer, which is stable and aesthetically pleasing.

This object is achieved by a liquid washing or cleaning agent comprising

a) a branched alkoxylated fatty alcohol having 5 to 12 alkoxy units and

b) a graying-inhibiting polymer. It has surprisingly been found that the combination of branched alkoxylated fatty alcohols with 5 to 12 alkoxy units with a graying-inhibiting polymer leads to stable washing or cleaning agent. Liquid detergents or cleaners with the combination of branched alkoxylated fatty alcohols with 5 to 12 alkoxy units and graying-inhibiting polymer show a high cleaning power and a very good grayness inhibition.

A particularly high cleaning performance and a particularly good grayness inhibition is when using branched alkoxylated fatty alcohols with 7 to 9 alkoxy units and especially when using 2-propylheptanol with 7 EO, 2-propylheptanol with 8 EO or a mixture of these two alcohols in the liquid washing or cleaning agents.

It is further preferred that the graying-inhibiting polymer is a graying-inhibiting polysaccharide, in particular a cellulose or a cellulose derivative. Graying-inhibiting polysaccharides, and in particular cellulose or cellulose derivatives, can be incorporated particularly well and stably into liquid detergents or cleaners containing a branched alkoxylated fatty alcohol having 5 to 12 alkoxy units. In addition, graying-inhibiting polysaccharides have particularly good graying-inhibiting properties.

In a preferred embodiment, the cellulose derivative is selected from the group consisting of carboxymethyl cellulose (CMC), an ether sulfonic acid salt of cellulose, an acidic sulfuric ester salt of cellulose, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, methyl hydroxyethyl cellulose,

Methylcarboxymethylcellulose, ethylhydroxyethylcellulose and a mixture of these

Cellulose derivatives. Particularly preferred cellulose derivatives include carboxymethylcellulose, hydroxypropylmethylcellulose, methylhydroxyethylcellulose or mixtures of two or more of these cellulose derivatives.

Other suitable graying-inhibiting polysaccharides include polyethylene glycol-modified celluloses and cellulose derivatives, especially polyethylene glycol-modified ones

Hydroxypropyl methylcellulose.

It may be preferable that the graying-inhibiting polysaccharide is acid-treated. By an acid treatment, the incorporation of the graying-inhibiting polysaccharide into a liquid matrix of a washing or cleaning agent can be further improved without losing the graying-inhibiting property of the graying-inhibiting polysaccharide. In a preferred embodiment, the washing or cleaning agent is packaged in a water-soluble wrapper.

Portion packs containing liquid detergents or cleaners on the one hand meet the consumer's desire for simplified dosage and on the other hand more and more consumers prefer liquid detergents or cleaners.

It may be preferred that the liquid washing or cleaning agent contains up to 10 wt .-%, based on the total detergent or cleaning agent, water.

Low-water liquid washing or cleaning agents are particularly advantageous for packaging in water-soluble wraps, since the risk of dissolution or dissolution of the water-soluble coating is minimized before using the liquid detergent or cleaning agent.

It is also preferred that the detergent or cleaning agent contain an amine neutralized anionic surfactant. The neutralization with amines does not lead to the formation of water and thus highly concentrated and / or low-water detergents or cleaning agents can be prepared, which are suitable for example directly for use in water-soluble coatings or can be offered in smaller packaging units.

Another object of the invention is the use of a branched alkoxylated fatty alcohol having 5 to 12 alkoxy units in a liquid detergent or cleaning agent with

graying-inhibiting polymer for increasing the stability of the liquid washing or

Detergent.

Particularly preferred cellulose derivatives include carboxymethyl cellulose, Hydroxypropylmethylcellulose, methylhydroxyethylcellulose or mixtures of two or more of these cellulose derivatives.

In a preferred embodiment, the cellulose or cellulose derivative is added before

** CMC 8036 R MV 350 (ex Chimibase SpA) To determine the graying inhibition, various test fabrics were used five times

Washed successively with 35 g each of the liquid detergent or cleaning agent E1, E2, V1 or V2 to be tested in a household washing machine (Miele W 1514) with 5 SBL 2004 wipes with standardized dirt load (32 g dirt ballast) at 40.degree.

After hanging drying and mangling of the laundry their whiteness was determined spectrophotometrically. The results clearly showed that by using a combination of a graying-inhibiting polymer and a branched alkoxylated fatty alcohol having 5 to 12 alkoxy units, no deterioration of graying-inhibiting performance compared to a liquid detergent or cleaning agent with a 7 EO C ₂ -8 fatty alcohol occurs, but all four detergents or cleaners have a very good graying-inhibiting performance.

However, the detergents V1 and V2 already showed a yellow sediment after one day while the detergents E1 and E2 after 12 weeks storage at 20 ° C. and 40 ° C. were stable and showed no turbidity or sediment. The washing or cleaning agent E2 had a particularly high transparency.

The "cloud points" of the liquid washing or cleaning agents E2 and V2 were determined according to DIN EN 23015. The cloud point is the highest temperature at which a cloud of crystals

(Turbidity) first occurs in a liquid when it is cooled under the specified test conditions.

The cloud point of the liquid detergent or cleaning agent E2 is 3 ° C while the sample of liquid detergent V2 remained cloudy at 40 ° C, 50 ° C, 60 ° C, 70 ° C and 80 ° C.

To produce a water-soluble packaging with the detergent or cleaning agent E1, a film of the type M 8630 (ex Monosol) with a thickness of 76 μητι was drawn to form a bulge by means of vacuum in a trough. Subsequently, the bulge was filled with 30 ml of liquid detergent or cleaning agent E1. After covering the agent filled bulges with a second layer of M 8630 film, the first and second layers were sealed together. The sealing temperature was 150 ° C and the sealing time 1, 1 seconds.

After 4, 8 and 12 weeks storage time of the water-soluble packaging with the detergent or cleaning agent E1 under various climatic conditions no arrival or dissolution of the water-soluble coating could be observed. In addition, no pores or holes, which would also lead to product leakage or leaks, were found.

Water-soluble packaging with the detergent or cleaning agent E1 dissolved in

Washes at temperatures ranging from 20 to 95 ° C, without residue on and showed a very good graying-inhibiting performance.
