Description

Move der Erfindung

[0001] This invention relates to the use of a, preferably aqueous, mixture R comprising at least one amphoteric surfactant T Amph and at least one biosurfactant S Bio to inhibit corrosion of a metal surface OM . It also relates to a method for treating, in particular washing or cleaning, preferably cleaning, a metal surface OM , where OM with the mixture R is contacted.

[0002] The present invention is based on the surprising finding that the mixture of at least one amphoteric surfactant T Ampn and at least one biosurfactant S Bio can synergistically prevent corrosion of metal surfaces, especially iron, better than the individual components T Amph or S Bio alone. Tech Stand

[0003] The state of the art discloses the use of biosurfactants such as rhamnolipids or sophorolipids to prevent corrosion of metal surfaces. Biosurfactants are considered sustainable and environmentally friendly alternatives to synthetically produced surfactants, and their use as corrosion inhibitors is attractive.

[0004] AA Jimoh et al., Front. Bioeng. Biotechnol. 2023, 11,1244595 (doi: 10.3389 / fbioe.2023.1244595) disclose on page 12 the anticorrosive effect of certain biosurfactants such as alkyl polyglucosides or rhamnolipids on metal surfaces such as steel or aluminum alloys.

[0005] The anticorrosive effect of rhamnolipids on steel surfaces is revealed by Z. Li et al., Corrosion Science 2022, 204, 110390.

[0006] US 9,884,986 B2 discloses that certain glycolipids, including rhamnolipids, cellobiose lipids, and trehalose lipids, exhibit corrosion-inhibiting properties on steel. This effect can be enhanced by the addition of certain additives such as formic acid and its salts, iodine and its salts, and metal oxides.

[0007] US Pat. No. 12,139,662 B2 discloses synergistic mixtures for inhibiting corrosion of carbon steel. These mixtures comprise a mixture of biosurfactants, particularly sophorolipids, and an additive such as esterquats and phosphate-containing compounds.

[0008] In light of these advances, there is still a need to enhance the corrosion-inhibiting effect of biosurfactants, preferably synergistically.

[0009] The object of the present invention was therefore to provide mixtures comprising biosurfactants which allow particularly good inhibition of the corrosion of metal surfaces, in particular of iron surfaces. Beschreibung der Erfindung 1. Missing R

[0012] The mixture according to the invention R Zeichnetare characterized by improved properties compared to the corresponding compositions of the prior art, in particular by a particularly good prevention of corrosion of the metal surface OM , which she is upset about.

[0013] In particular, it was surprisingly found that the corrosion of the metal surface OM when using the combination of at least one amphoteric surfactant T Amph and at least one biosurfactant S Bio is particularly well prevented, especially in comparison to the corrosion of the metal surface OM , if they are used in the same amount with only one of the two components (amphoteric surfactant T All amp or biosurfactant S Bio alone).

However, particular preference is given to alcohol ethoxylates with linear residues from alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, tallow fat or oleyl alcohol, and on average 2 to 8 IS per mole of alcohol. Preferred ethoxylated alcohols include, for example, C 12 -C 14 alcohols with 3 YES, 4 YES or 7 IS, C 9 -C 11 alcohols with 7 IS, C 13 -C 15 -alcohols with 3 IS, 5 IS, 7 IS or 8 IS, C 12 -C 18 alcohols with 3 IS, 5 IS or 7 IS and mixtures thereof, such as mixtures of C 12 -C 14 alcohols with 3 ISand C 12 -C 18 alcohols with 7 EO.

The polysaccharide is preferably selected from the group consisting of cellulose and cellulose derivatives. Another β-1,4-linked polysaccharide with an affinity for cellulose, such as polymannan, polyglucan, polyglucomannan, polyxyloglucan, and polygalactomannan, or a mixture thereof, may also be used. The polysaccharide can also be selected from the group consisting of polyxyloglucan (also referred to as "xyloglucan") and polygalactomannan (also referred to as "galactomannan").

[0196] Preferred polymannans are acetylated polymannan polysaccharides.

The most preferred deposition aid is AD Locust bean gum. Preferably, the backbone of the separating agent AD The polysaccharide used only has β-1,4 bonds.

[0198] Optionally, the separation aid AD The polysaccharide used has additional linkages to the β-1,4 linkages, for example β-1,3 linkages. Thus, additional linkages are optionally present. AD Polysaccharides can also be used which have polysaccharide backbones which (whether terminal or within the polysaccharide chain) contain a material or chemical structure which is not a saccharide ring.

[0199] The separation aid ADThe polysaccharide used can be straight or branched.

[0200] Many naturally occurring polysaccharides exhibit at least some degree of branching, or at least some saccharide rings are present in the form of pendant side groups on a main polysaccharide backbone (which are preferably not taken into account when determining the degree of substitution).

[0203] "Entanglement" here means that the separation aid AD During polymerization and with increasing particle size on the particle, especially the active ingredient capsule WK , is adsorbed, whereby a part of the adsorbed deposition aid AD inside the particle, especially the active ingredient capsule WK , is buried. Therefore, at the end of the polymerization, part of the deposition aid AD in the polymer matrix of the particle, especially the active ingredient capsule WK , enclosed and bound, while the rest escapes unhindered and, if the particle, especially the active ingredient capsule WK , is present in the mixture R, contacts the mixture R or can extend into it.

[0204] Adsorption here means in particular the adsorption of the separation aid AD on the surface of the particle, especially the active ingredient capsule WK , such adsorption can be due, for example, to hydrogen bonds, van der Waals bonding or electrostatic attraction between the deposition aid AD and the particle, especially the active ingredient capsule WK , The separation aid AD In this embodiment, therefore, it adheres mainly to the surface of the particle, in particular the active ingredient capsule WK , and does not distribute to any significant extent inside the particle, especially the active ingredient capsule WK .

[0205] This differs from graft copolymers, where, for example, a polysaccharide can be grafted along the length of a polymer chain.

[0206] A particle, in particular an active ingredient capsule WK , which is formed from a graft copolymer, would therefore contain polysaccharides throughout the entire interior of the particle as well as on the particle surface. This type of particle can be used in the context of the present invention, but is less than an active ingredient capsule. WK Thus, the particle that forms when a polysaccharide is used as a separation aid AD according to the method of the invention as an active ingredient capsule WK The resulting graft copolymer can be thought of as a "hairy particle," which is different from a graft copolymer. This feature of the invention offers the manufacturer significant cost-reduction opportunities, as much less deposition aid is required to achieve the same level of activity as in systems using polysaccharide copolymers.

Experimental procedure

[0268] An ST 35 structural steel plate was sprayed with various test solutions obtained by diluting the formulations 1) to 10) described below at a ratio of 1:200 in hardened water of 16 °dGH from a trigger spray bottle, ensuring complete coverage. After 30 minutes, the plate was sprayed again. After 120 minutes, the plate was rinsed with ethanol and allowed to dry. A visual evaluation of the resulting corrosion was performed immediately.

[0269] The individual components in the following formulations 1) to 10) were tested. These were biosurfactants [rhamnolipids in formulation 2), sophorolipids in formulation 4)], the amphoteric surfactant sodium cocoamphopropionate [in test formulation 2)], and other surfactants commonly used in car shampoos [in test formulations 4) to 9)]. For comparison, a test solution without surfactant (only the preservative phenoxyethanol) was tested in test formulation 10).

[0270] The exact composition of formulations 1) to 10) was as follows: 1.) 74% water, 8% by weight Rewoferm RL 210, 17.5% by weight Rewoteric AM KSF 40 MB, 0.5% by weight phenoxyethanol; 2.) 77.5% water, 22% by weight Rewoferm RL 210, 0.5% by weight phenoxyethanol; 3.) 72% water, 27.5% Rewoteric AM KSF 40 MB, 0.5% phenoxyethanol; 4.) 76.1% water, 23.4% Rewoferm SL ONE, 0.5% phenoxyethanol; 5.) 83.3% water, 15.7% Texapon N 70, 0.5% phenoxyethanol; 6.) 85.8% water, 13.8% Marlon ARL, 0.5% phenoxyethanol; 7.) 88.5% water, 11% Plantacare 818 UP, 0.5% phenoxyethanol; 8.) 88.5% water, 11% Tomadol 91-6, 0.5% phenoxyethanol; 9.) 76.1% water, 13.8% Tego Betaine C 60, 0.5% phenoxyethanol; 10.) 99.5% water, 0.5% phenoxyethanol. 3. Results

[0271] The evaluation of each treated panel was performed visually, and the corrosion was categorized according to the size of the corroded surface on a scale from 0 (no signs of corrosion) to 10 (severe corrosion). The results were as follows: formulation 1) 2) 3) 4) 5) 6) corrosion 0 0.5 2 1.5 10 3 formulation 7) 8) 9) 10) corrosion 6 5 3 8

[0272] The individual components in test formulations 2), 3) and 4) produced only minimal corrosion, i.e., individual, small rust spots on the plate (values ​​from "0.5" to "2").

[0273] Formulation 1) showed a further improvement compared to formulations 2) to 4): When using formulation 1), not even a single rust spot was observed. Thus, the surfactant combination in formulation 1) was the only one that did not produce any corrosion on the steel sheet (value "0"), demonstrating a qualitative improvement in the anti-corrosion effect compared to formulations 2) to 4).

[0274] It turns out that, surprisingly, the combination of biosurfactants (here RL, but also SL) on the steel sheets, corrosion was particularly well prevented. Corrosion is thus only combinationfrom biosurfactants (Rewoferm RL 210) and amphoteric surfactants (Rewoteric AM KSF 40) as in formulation 1). If the respective surfactants are used individually [formulations 2) to 4)] in the same amount, corrosion, albeit minimal, is observed.

[0275] It is therefore a synergistic effect.
