The NTU is a unit measuring the lack of clarity of liquids and is used by water and sewage treatment plants, in marine studies, for example. For example, water containing 1 milligram of finely divided silica per liter has a turbidity of 1 NTU. The water to be measured is placed in a standard container. A light beam passes through the water and strikes a sensor on the other side of the container. A second sensor is mounted at right angles to the beam, measuring light scattered by particles in the water. From the ratio between the light intensities at the two sensors the turbidity in NTU can be calculated.

Prod. Of Gary, Ind., US) plus plasticizers like glycerol, ethylene glycerol, Propylene glycol, sorbitol and mixtures thereof. The pouches can comprise a solid laundry detergent composition or part components and/or a liquid cleaning composition or part components separated by the water-soluble film. The compartment for liquid components can be different in composition than compartments containing solids, see for example US20090011970.

Detergent ingredients can be separated physically from each other by compartments in water dissolvable pouches or in different layers of tablets. Thereby negative storage interaction between components can be avoided. Different dissolution profiles of each of the compartments can also give rise to delayed dissolution of selected components in the wash solution.

The detergent composition according to the instant invention can be in form of a laundry soap bar and used for hand washing laundry, fabrics and/or textiles. The term laundry soap bar includes laundry bars, soap bars, combo bars, syndet bars and detergent bars. The types of bar usually differ in the type of surfactant they contain, and the term laundry soap bar includes those containing soaps from fatty acids and/or synthetic soaps. The laundry soap bar has a physical form which is solid and not a liquid, gel or a powder at room temperature. The term solid is defined as a physical form which does not significantly change over time, i.e. if a solid object (e.g. laundry soap bar) is placed inside a container, the solid object does not change to fill the container it is placed in. The bar is a solid typically in bar form but can be in other solid shapes such as round or oval.

The detergent composition according to the instant invention can be formulated as a granular detergent as described in WO09/092699, EP1705241, EP1382668, WO07/001262, U.S. Pat. No. 6,472,364, WO04/074419 or WO09/102854.

The detergent composition according to the instant invention preferably is in the form of a liquid or gel detergent. This may be aqueous, typically containing at least 20% by weight water, with the percentages referring to the total composition. Other types of liquids, including without limitation, alkanols, amines, diols, ethers and polyols may be included in an aqueous liquid or gel. An aqueous liquid or gel detergent composition may contain from 0-30 wt.-% organic solvent, with the percentages referring to the total composition. A liquid or gel detergent may be non-aqueous.

A preferred composition according to the invention is characterized in that the pH of the composition at 25° C. is from 3.0 to 10.0, preferably from 4.0 to 9.5 and particularly preferably from 7.0 to 9.0.

The “pH” in connection with the present invention—unless stated otherwise—is defined as the value which is measured for the relevant composition at 25° C. after stirring for five minutes using a pH electrode calibrated in accordance with ISO 4316 (1977).

The instant invention further provides a process for cleaning a surface of an article, preferably a textile or a fabric, comprising the steps of

A preferred process according to the instant invention is characterized in that the weight ratio of the provided article and water in step b) and c) are in the range of from 1:2 to 1:30, preferably from 1:3 to 1:25, more preferably from 1:4 to 1:20.

A preferred process according to the instant invention is characterized in that in step b) per kg of water 0.1 g to 50 g, preferably 1.0 g to 20 g, more preferably 2.0 g to 10 g, composition according to the instant invention are provided.

The instant invention further provides the use of a composition according to the instant invention for cleaning a surface of an article, preferably a textile or a fabric.

Preferably the use according to the instant invention is characterized in that the surface of the article is cleaned from fat and/or oil, preferably from solid fatty stains.

The examples adduced hereinafter describe the present invention by way of example, without any intention that the invention, the scope of application of which is apparent from the entirety of the description and the claims, be restricted to the embodiments specified in the examples.

EXAMPLES

Rhamnolipids used were prepared as described in example 1 of EP3061442 and resemble di-rhamnolipids; mono-rhamnolipids were prepared as in example 2 of EP3061442.

The sophorolipid used is a sophorolipid REWOFERM SL ONE from Evonik, which has a lactone to acid ratio of 40:60.

Glucolipids were produced according to example 2 of WO2019154970 via fermentation

The following formulations were prepared with the numbers given being weight percentages of active matter, Benchmark 1 and Benchmark 2 (commercially available detergents) as well as Benchmark 3, Benchmark 4 and Benchmark 5 (internal available detergents) being not according to the invention, Detergent 1-6 according to the invention:

The used stains were purchased form CFT (Vlaardingen, Nederland's) which was also recommended by A.I.S.E (Laundry Detergent Testing Guidelines)

After the washing, the fabrics were rinsed and then dried in the air.

The evaluation of the degree of stain removal was carried out measuring the reflectance via spectrophotometer, using the Y-value of the Y, x, y color coordinates measurement, light source D65 with a UV cut-off filter at 420 nm. Aperture used for real stains 15 mm (minimum 12 mm). Stains were measured unfolded, 3 measurements per stain (in the center of the circular area, or closest homogenous area) so 18 times per stain. Measurements were taken on each stain before wash (to verify quality of stains) and after the wash and to evaluate standard deviations and are reported.

Results are expressed as the mean of value Y between three replicates and its standard deviation (σ) and shown in table 8 to 14. The better the soil removal, the larger the Y value.

It was surprisingly found that the addition of the component persicomycin to the biosurfactant-based detergent formulation will lead to a better cleaning performance with regards to stain removal. Especially in the case of fatty stains the combination outperformed both the formulations without persicomycin (Benchmarks 3, 4 and 5) and commercially available formulations (Benchmarks 1 and 2). Moreover, the addition of persicomycin is leading to a higher overall formulation viscosity that would very much fit with market and consumer expectations for liquid laundry detergents.
