权利要求: 1. Thixotropic corrosion protection additives, comprising: a mixture of at least one dialkylbenzenesulphonate and a coconut fatty acid, wherein the quantitative ratio of the dialkylbenzenesulphonate to the coconut fatty acid is 5:1 to 1:5.2. Thixotropic corrosion protection additives according to claim 1, wherein the dialkylbenzenesulphonate is a compound or a mixture of compounds where alkyl is a C8-C24-alkyl.3. Thixotropic corrosion protection additives according to claim 1, wherein the dialkylbenzenesulphonate comprises a mixture of dialkylbenzenesulphonates.4. A process for the preparation of the thixotropic corrosion protection additives according to claim 1, comprising: reacting the at least one dialkylbenzenesulphonic acid with at least one base and then adding thereto the coconut fatty acid.5. Carrier substances comprising the thixotropic corrosion protection additive according to claim 1.6. Carrier substances according to claim 5, wherein said carrier substances are oils, solvents or fats.7. Process for preserving liquids of lubrication greases, comprising:adding the thixotropic corrosion protection additives according to claim 1 to said preserving liquids of lubrication greases.8. A process for the preparation of the thixotropic corrosion protection additives according to claim 1, comprising:neutralizing the dialkylbenzenesulphonic acid with a base in the presence of the coconut fatty acid.9. Thixotropic corrosion protection additives, comprising: a mixture of at least one dialkylbenzenesulphonate and a coconut fatty acid, wherein the quantitative ratio of the dialkylbenzenesulphonate to the coconut fatty acid is 3:1 to 1:3.
