Detergent formulation for textiles, comprising rhamnolipids with a predominant content of di-rhamnolipids
View Patent ↗The invention relates to detergent formulations for textiles, comprising rhamnolipids, where the content of di-rhamnolipids predominates, and to the use of certain rhamnolipid mixture compositions and of the aforementioned detergent formulations for increasing the rate of foam formation and/or for foam stabilization, and to the use of rhamnolipids for preventing the greying of a textile.
1. A detergent formulation for textiles, comprising a mono- and di-rhamnolipid mixture composition, wherein a weight ratio of said di-rhamnolipids to said mono-rhamnolipids is greater than 97:3.
2. The detergent formulation according to claim 1 , wherein said rhamnolipid mixture composition comprises
51% by weight to 95% by weight of diRL-C10C10, and
0.5% by weight to 9% by weight of monoRL-C10C10,
where the percentages by weight refer to the sum of all of the rhamnolipids present.
3. The detergent formulation according to claim 2 , wherein said rhamnolipid mixture composition further comprises
0.5% by weight to 15% by weight of diRL-C10C12:1,
where the percentages by weight refer to the sum of all of the rhamnolipids present.
4. The detergent formulation according to claim 2 , wherein said rhamnolipid mixture composition further comprises
0.5 to 25% by weight of diRL-C10C12,
where the percentages by weight refer to the sum of all of the rhamnolipids present.
5. The detergent formulation according to claim 2 , wherein said rhamnolipid mixture composition further comprises
0.1% by weight to 5% by weight of monoRL-C10C12, and
0.1% by weight to 5% by weight of monoRL-C10C12:1,
where the percentages by weight refer to the sum of all of the rhamnolipids present.
6. The detergent formulation according to claim 2 , wherein said rhamnolipid mixture composition further comprises
0.5% by weight to 15% by weight of diRL-C10C12:1,
0.5 to 25% by weight of diRL-C10C12,
0.1% by weight to 5% by weight of monoRL-C10C12 and
0.1% by weight to 5% by weight of monoRL-C10C12:1,
where the percentages by weight refer to the sum of all of the rhamnolipids present.
7. The detergent formulation according to claim 2 , wherein said rhamnolipid mixture composition further comprises
0% by weight to 5% by weight of diRLC10,
where the percentages by weight refer to the sum of all of the rhamnolipids present.
8. The detergent formulation according to claim 1 , further comprising a surfactant.
9. The detergent formulation according to claim 8 , wherein said surfactant is selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants and amphoteric surfactants.
10. The detergent formulation according to claim 8 , wherein said surfactant is selected from the group of sulphonates and sulphates.
11. The detergent formulation according to claim 10 , wherein said surfactant is a liner alkylbenzenesulphonate.
12. A method of washing textiles comprising adding a detergent formulation according to claim 1 to said textiles.
