Definitions
- the present invention relates to cleaning compositions. More specifically, the invention relates to cleaning compositions with preservative effect for cleaning offshore wind turbines.
- Wind turbines are subject to continued pollution. These contaminants are partly due to assembly and transport dirt, but is also generated from oil leaks from the nacelle flowing down the tower. However, especially for offshore wind turbines, most of the contamination are airborne contaminants (including feces of birds). Microorganisms (including algae, fungi and lichens) then secondarily colonize the contaminants.
- One object of the present invention is to reduce or retard the colonization of microorganisms on offshore wind turbines.
- a cleaning/coating composition comprising a combination of wax and a considerable amount of an organic acid will prolong the surface resistance to colonization of microorganisms onto an offshore wind turbine.
- the cleaning composition also comprises a surfactant for better cleaning of the surface, as well as for mixing the wax and the or- ganic acid.
- the mixture of wax and organic acid form a surface coating thereon.
- the organic acid then slowly diffuses out of the wax, thereby killing colonized microorganisms, and prevent new ones from settling.
- microorganisms includes, but is not limited to, bacteria, fungi, algae, and protozoans.
- One aspect relates to the use of a cleaning composition
- a cleaning composition comprising wax, surfactant, organic acid, and at least one solvent for cleaning a wind turbine, wherein the solvent is selected from the group consisting of water, an alcohol, or mixtures thereof.
- a second aspect relates to the use of a cleaning composition
- a cleaning composition comprising wax, surfactant, organic acid, and at least one solvent for cleaning an off- shore structure positioned above the sea level, wherein the solvent is selected from the group consisting of water, an alcohol, or mixtures thereof.
- a third aspect relates to a cleaning composition
- a cleaning composition comprising a wax, surfactant, organic acid, and at least one solvent, wherein the solvent is selected from the group consisting of water, an alcohol, or mixtures thereof.
- the solvent is water, since it aids in the forming of an emulsion of wax-organic acid-surfactant droplets.
- the cleaning composition comprises solvent, preferably water, in an amount of 10-96% vol/vol, such as within the range of 15-90% vol/vol, e.g. within the range of 20-85% vol/vol, such as within the range of 25-80% vol/vol, such as within the range of 30-75% vol/vol, e.g. within the range of 35-70% vol/vol, such as within the range of 40-65% vol/vol, e.g. within the range of 45-60% vol/vol, such as within the range of 50-55% vol/vol.

- the mode of action of an organic acid is that the non-dissociated acids penetrate the microorganism cell wall via passive diffusion and disrupt the normal physiology of the cell in two ways.
- the acids dissociate and therefore lower the internal pH, which is normally close to neutral, impairing the function of the microorganism.
- the anionic part of the acid that is unable to leave the cell in its dissociated form, accumulates within the cell, disrupting metabolic functions and increasing osmotic pressure.
- the organic acid is selected from the group consisting of citric acid, benzoic acid, propionic acid, tartaric acid, acetic acid, oxalic acid, malic acid, salicylic acid, lactic acid, gluconic acid, hydroxyacetic acid, and mixtures thereof.

Description
CLEANING COMPOSITION WITH PRESERVATIVE EFFECT FOR CLEANING AN OFFSHORE WIND TURBINE
Technical field of the invention
The present invention relates to cleaning compositions. More specifically, the invention relates to cleaning compositions with preservative effect for cleaning offshore wind turbines.
Background of the invention
Wind turbines are subject to continued pollution. These contaminants are partly due to assembly and transport dirt, but is also generated from oil leaks from the nacelle flowing down the tower. However, especially for offshore wind turbines, most of the contamination are airborne contaminants (including feces of birds). Microorganisms (including algae, fungi and lichens) then secondarily colonize the contaminants.
The contaminants excreted by the organisms of secondary colonization pose a considerable risk of corrosion for wind turbines, particularly in the offshore area, where the air is very moist and saline. Furthermore, the contamination increases the noise from the wind turbines, and result in a negative aesthetic impression.
For these reasons, it is necessary to clean the entire offshore wind turbine several times a year. The cleaning of offshore wind turbines is very expensive. The cleaning is performed manually, e.g. using lifts. This approach requires considerable labor, time and cost.
Summary of the invention
One object of the present invention is to reduce or retard the colonization of microorganisms on offshore wind turbines.
The inventor have found that a cleaning/coating composition comprising a
combination of wax and a considerable amount of an organic acid will prolong the surface resistance to colonization of microorganisms onto an offshore wind turbine. The cleaning composition also comprises a surfactant for better cleaning of the surface, as well as for mixing the wax and the or- ganic acid. When applied to an offshore wind turbine, the mixture of wax and organic acid form a surface coating thereon. The organic acid then slowly diffuses out of the wax, thereby killing colonized microorganisms, and prevent new ones from settling. In the present context, the meaning of "microorganisms" includes, but is not limited to, bacteria, fungi, algae, and protozoans.
One aspect relates to the use of a cleaning composition comprising wax, surfactant, organic acid, and at least one solvent for cleaning a wind turbine, wherein the solvent is selected from the group consisting of water, an alcohol, or mixtures thereof.
A second aspect relates to the use of a cleaning composition comprising wax, surfactant, organic acid, and at least one solvent for cleaning an off- shore structure positioned above the sea level, wherein the solvent is selected from the group consisting of water, an alcohol, or mixtures thereof.
A third aspect relates to a cleaning composition comprising a wax, surfactant, organic acid, and at least one solvent, wherein the solvent is selected from the group consisting of water, an alcohol, or mixtures thereof.
Preferably, the solvent is water, since it aids in the forming of an emulsion of wax-organic acid-surfactant droplets. In one or more embodiments, the cleaning composition comprises solvent, preferably water, in an amount of 10-96% vol/vol, such as within the range
of 15-90% vol/vol, e.g. within the range of 20-85% vol/vol, such as within the range of 25-80% vol/vol, such as within the range of 30-75% vol/vol, e.g. within the range of 35-70% vol/vol, such as within the range of 40-65% vol/vol, e.g. within the range of 45-60% vol/vol, such as within the range of 50-55% vol/vol.
Too much organic acid may damage the surface of the offshore structure due to its corrosive properties, and too little will not result in long-term protection from microorganisms. The use of inorganic acid did not result in in long-term protection from microorganisms. Without being bound by any theory, it is speculated that it is difficult to incorporate the inorganic acid in the surfactant droplets. Furthermore, the organic acid is thought in itself to be antimicrobial. In one or more embodiments, the cleaning composition comprises organic acid in an amount of 0.5-5% vol/vol, such as within the range of 0.75-4.75% vol/vol, e.g. within the range of 1.00-4.50% vol/vol, such as within the range of 1.25-4.75% vol/vol, e.g. within the range of 1.00-4.25% Vol/vol, such as within the range of 1.50-4.00% vol/vol, e.g. within the range of 1.75-3.75% vol/vol, such as within the range of 2.00-3.50% vol/vol, e.g. within the range of 2.25-3.25% vol/vol, such as within the range of 2.50-3.00% vol/vol.
In one or more embodiments, the cleaning composition comprises organic acid in an amount of 0.5-3% vol/vol, such as within the range of 0.75-2.75% vol/vol, e.g. within the range of 1.00-2.50% vol/vol, such as within the range of 1.25-1.75% vol/vol.
There seems to be a minimum limit to the amount of acid that can be present in the wax or wax containing droplet for the acid to diffuse to the sur- face of the coating. At the same time, there seems to be a maximum limit on how much acid that can be incorporated in the wax or wax containing
droplet.
In one or more embodiments, the volume ratio between the organic acid and the wax is within the range of 1 :1-1 :20, e.g. within the range of 1 :1.5- 1 :15, such as within the range of 1 :1.75-1 :14, e.g. within the range of 1 :2- 1 :13, such as within the range of 1 :2.25-1 :12, e.g. within the range of 1 :2.5- 1 :11 , such as within the range of 1 :2.75-1 :10, e.g. within the range of 1 :3- 1 :9, such as within the range of 1 :3.25-1 :8, e.g. within the range of 1 :3.5- 1 :7, such as within the range of 1 :375-6, e.g. within the range of 1 :4-1 :5, preferably within the range of 1 :1 25-1 :5.

Without being bound by any theory, it is speculated that the mode of action of an organic acid is that the non-dissociated acids penetrate the microorganism cell wall via passive diffusion and disrupt the normal physiology of the cell in two ways. The acids dissociate and therefore lower the internal pH, which is normally close to neutral, impairing the function of the microorganism. The anionic part of the acid, that is unable to leave the cell in its dissociated form, accumulates within the cell, disrupting metabolic functions and increasing osmotic pressure.
In one or more embodiments, the organic acid is selected from the group consisting of citric acid, benzoic acid, propionic acid, tartaric acid, acetic acid, oxalic acid, malic acid, salicylic acid, lactic acid, gluconic acid, hydroxyacetic acid, and mixtures thereof.
As used herein, the term "organic acid" is also referring to its salt.
It has been discovered that using combinations of at least two organic acids or their salts, provides synergistic microbial control.
In one or more embodiments, the organic acid is a mixture of at least two
different organic acids selected from the group consisting of citric acid, benzoic acid, propionic acid, tartaric acid, acetic acid, oxalic acid, malic acid, salicylic acid, lactic acid, gluconic acid, hydroxyacetic acid, and mixtures thereof.
The selection of the organic acid may be dependent on the chosen type of wax and vice versa.

Examples
The main object of this study was to test if the colonization of microorganisms on an offshore wind turbine could be retarded by treatment with a cleaning composition according to the present invention,
A series of tests were conducted with varying concentrations of wax and organic acids, as well as ratios between wax and organic acid. An exemplary cleaning composition is made by mixing 10% vol/vol nonionic surfactant (e.g. CAS number: 69011-36-5), 2.5% vol/vol cationic surfactant (e.g. CAS number: 863679-20-3), 4% vol/vol carnauba wax, 1.3% vol/vol glacial acetic acid, and 82.2% vol/vol water. Surfactants and wax are first mixed with about half of the water. Secondly, the glacial acetic acid is diluted in the remaining water, and the two solutions are then subsequently mixed. All components are easily commercially available.
When using organic acid in an amount of at least 0.5% vol/vol, surfactant in an amount of at least 9 times the amount of acid (1 :9 ratio or more), and where the volume ratio between the organic acid and the wax was within the range of 1 :1-1 :15, it was possible to retard the colonization of microorganisms on an offshore wind turbine with at least 30 months (testing still ongoing). Hence, the cleaning frequency of e.g. an offshore wind turbine can be extended from 12 months to at least 30 months,
