Description

"Performance Enhanced Detergents or Detergents with Complexing Agents II"

The invention relates to performance-enhanced detergents or cleaners that certain

Complexing agent included.

The most important constituents of the water hardness are salts of calcium and magnesium, in particular chlorides, sulfates and bicarbonates, which are known as so-called hardness images. Since the bicarbonates are converted into carbonates under thermal stress, a part of the calcium salts precipitates as poorly soluble CaC0 ₃ , especially in washing and cleaning operations at elevated temperatures. At high magnesium concentrations, basic magnesium carbonates are also formed. Contain the detergents and cleaning agents themselves carbonates, for example in the form of alkali metal carbonates or other precursors such

For example, percarbonates, which can release carbonate during the washing process, this carbonate content promotes the formation of insoluble calcium and magnesium carbonate residues.

The removal of hardness-forming Ca / Mg ions from aqueous solutions by ion exchange or complexation is therefore an important step in washing and cleaning processes.

Conventional complexing agents commonly used in detergents and cleaners are

Phosphonates, polycarboxylates, gluconates, NTA and EDTA. These products are not or only partially produced on the basis of renewable raw materials, which phosphonates, NTA and EDTA can still lead to an environmentally harmful contamination of the wastewater.

For some complexing agents, it has been demonstrated that they can increase the cleaning performance of detergents and cleaners. For example, EP 0 970 167 B1 discloses processes for improved cleaning of hard and textile surfaces by using tetrasodiumiminodisuccinate (also: iminodisuccinate tetrasodium salt, Λ- (1,2-dicarboxyethyl) aspartic acid tetrasodium salt, and the salts are also called iminodisuccinates (IDS) ).

Fabric detergents which contain 0.5 to 5% by weight of alkali metal salts as bleaching agents and 0.05 to 5% by weight of IDS or OH-substituted IDS (HIDS) are disclosed in WO 2001/88077 A1. This paper also mentions the bleach-stabilizing effect of IDS.

Despite these findings, detergents containing IDS or HIDS are still

improvement. In particular, so-called "enzymatic soiling" (ie Stains that are removed by enzymes such as milk, egg, starch, etc.) are still in need of improvement.

Water.

In addition, nonaqueous solvents can be added to the washing or cleaning agent. Suitable non-aqueous solvents include mono- or polyhydric alcohols, alkanolamines or glycol ethers, provided that they are miscible with water in the specified concentration range.

In addition to these constituents, a liquid washing or cleaning agent may contain dispersed particles whose diameter along their greatest spatial extent is preferably 1 to 2000 μm.

For the purposes of the present invention, particles may be capsules, abrasives as well as powders, granules or compounds of compounds which are insoluble in the washing or cleaning agent, with capsules being preferred.

The term "capsule" on the one hand understood aggregates with a core-shell structure and on the other hand aggregates with a matrix. Core-shell capsules contain at least one solid or liquid core which is enclosed by at least one continuous shell, in particular a shell of polymer (s).

Inside the capsules, sensitive, chemically or physically incompatible as well as volatile components (= active ingredients) of the liquid washing or cleaning agent can be enclosed stable in storage and transport. In the capsules, for example, optical brighteners, surfactants, complexing agents, bleaching agents, bleach activators, dyes and fragrances, antioxidants, builders, enzymes, enzyme stabilizers, antimicrobial agents, grayness inhibitors,

Anti redeposition agents, pH adjusters, electrolytes, detergency boosters, vitamins, proteins, Foam inhibitors and UV absorbers are located. The fillings of the capsules may be solids or liquids in the form of solutions or emulsions or suspensions.

The capsules may have any shape in the production-related framework, but they are preferably approximately spherical. Their diameter along their largest spatial

Expansion can be between 1 [im and 2000 μητι depending on the components contained in its interior and the application.

Alternatively, it is also possible to use particles which have no core-shell structure but in which the active substance is distributed in a matrix of a matrix-forming material. Such particles are also referred to as "matrix particles".

The matrix formation in these materials takes place for example via gelation, polyanion-polycation interactions or polyelectrolyte-metal ion interactions and is well known in the art as well as the production of particles with these matrix-forming materials. An exemplary matrix-forming material is alginate. For the production of alginate-based speckles is an aqueous alginate solution, which also includes the active ingredient or the

containing active ingredients, dripped and then cured in a Ca ²⁺ -ions or Al ³⁺ ions-containing precipitation bath. Alternatively, other, matrix-forming materials can be used instead of alginate.

The capsules can be stably dispersed in the liquid detergents or cleaners. Stable means that the detergents or cleaning agents are stable at room temperature for a period of at least 4 weeks, and preferably for at least 6 weeks, without the particles in the medium creaming or sedimenting.

The release of the active ingredients from the capsules is usually carried out by destruction of the shell or the matrix due to mechanical, thermal, chemical or enzymatic action.

In a preferred embodiment, the liquid detergents or cleaners contain capsules in which one or more fragrances are contained.

Alternatively, the particles may comprise abrasives such as plastic or calcium carbonate beads as well as powders, granules or compounds of compounds insoluble in the detergent or cleaning agent.

In a preferred embodiment of the invention, the liquid washing or contain

Detergent identical or different particles in amounts of 0.05 to 10 wt .-%, in particular 0.1 to 8 wt .-% and most preferably 0.2 to 5 wt .-%. A further subject of the present invention relates to the use of compounds of the formula (I)

in the

R ^{1 is} -H, -CH ₃ , -CH ₂ -CH ₃ , - (CH ₂ ) ₂ -CH ₃ , -CH- (CH ₃ ) ₂ or - (CH ₂ ) _n -CH ₃ where n =

4, 5, 6, 7, 8, 9, 10 or 11;

X represents a hydrogen atom, a monovalent cation or the n-th part of an n-valent cation,

Improvement of stain removal.

A further subject of the present invention relates to the use of compounds of the formula (I)

in the

4, 5, 6, 7, 8, 9, 10 or 11;

Improvement of the removal of enzymatic soiling.

With respect to preferred embodiments of the uses according to the invention mutatis mutandis applies to the surfactant systems according to the invention and liquid washing or

Detergents said. Examples:

Example 1 Caicium binding capacity

The calcium binding capacity of the complexing agents used according to the invention was tested by adding to 250 ml of water having a pH of 8.5 or 10 and 30 ° dH at 25 ° C. 5 ml of a solution (1 g / l) of the complexing agent used according to the invention and the pH Value, if necessary, was readjusted to 8.5 or 10 again. Then, after 5 minutes using a calcium-sensitive electrode, the residual hardness of the solutions was determined.

Table 1: Residual hardness

DHEI: N- (1,2-dicarboxy-2-hydroxyethyl )iminiodiacetic acid, Na salt

IDS: iminodisuccinic acid, Na salt

HIDS: N- (1,2-dicarboxy-2-hydroxyethyl) aspartic acid, Na salt

The results show that the calcium binding capacity of IDS is worse than that

Caicium binding capacity of the compound used according to the invention (DHEI). The compound used according to the invention achieves the Caiciumbindeabmögen of HIDS or even exceeds it at pH = 10 even significantly.

For the washing tests, household washing machines (Miele W 1514) were loaded with 3.5 kg accompanying laundry as well as soiled cloth rags. In addition, 80g / 75ml of the to be tested

Detergent added and washed at 40 ° C. Detergent B from Table 2 was used as a reference and compared with the detergent A according to the invention, which contained 1.5% of the complexing agent used according to the invention. After hanging drying and mangling of the cloth rags their whiteness was determined spectrophotometrically (Minolta CR400-1).

The values given (Table 3) are mean values of 6 determinations. The soiled textiles were bought. Shown are the differences of the remission values to the standard detergent B and the errors in the 6-fold determination (LSD).

The addition of the complexing agent leads to improvements in the leachability of various

Soiling, in particular on enzymatic but also on greasy and bleach-sensitive stains.
