View Patent ↗The invention relates to a mixture composition comprising rhamnolipids, to a process for its preparation, to its use for producing formulations and to formulations comprising this mixture composition.
1. A cosmetic composition comprising a mixture of rhamnolipids, wherein said mixture comprises
51% by weight to 95% by weight of diRL-C10C10,
0.5% by weight to 3% by weight of monoRL-C10C10, and 0.5 to 25% by weight of diRL-C10C12
where the percentages by weight refer to the sum of all of the rhamnolipids present, and with the proviso that a weight ratio of said di-rhamnolipids to said mono-rhamnolipids is greater than 97:3, wherein said mixture comprises at tleast 60% by weight of rhamnolipids, and wherein the percentages by weight refer to the dry substance of the overall mixture.
2. The cosmetic composition according to claim 1 , wherein said mixture further comprises
0.1% by weight to 5% by weight of monoRL-C10C12,
where the percentages by weight refer to the sum of all of the rhamnolipids present.
3. A cosmetic composition comprising a mixture of rhamnolipids, wherein said mixture 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.
4. The cosmetic composition according to claim 1 , wherein said mixture 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.
5. The cosmetic composition of claim 1 , wherein said mixture further comprises
0.5% to 15% by weight of diRL-C10C12.1,
where the percentages by weight refer to the sum of all the rhamnolipids present.
6. A cosmetic composition comprising a mixture of mono-rhamnolipids and di-rhamnolipids, wherein a weight ratio of said di-rhamnolipids to said mono-rhamnolipids is greater than 97:3.
7. The cosmetic composition of any one of claims 1 and 6 further comprising at least one cosmetic active ingredient.
