Abstract

The invention relates to an oleogel-forming agent which comprises at least one highly dispersed triterpene. The invention also relates to an oleogel which comprises a nonpolar liquid in an amount ranging from 80% by weight to 99% by weight based on the total weight of the oleogel and an oleogel-forming agent comprising a highly dispersed triterpene in an amount ranging from 1% by weight to 20% by weight based on the total weight of the oleogel. The invention also relates to a method for producing an oleogel.

Claims (11)

1. A method for producing a triterpene-containing oleogel, comprising:

forming an oleogel using at least one highly dispersed triterpene having an average particle size of less than 50 μm that acts as an oleogel-forming agent in the oleogel, wherein the at least one highly dispersed triterpene is the only oleogel-forming agent in the oleogel.

2. The method as recited in claim 1 , wherein the average particle size of the at least one triterpene is less than 10 μm.

3. The method as recited in claim 1 , wherein the proportion of secondary agglomerates of the at least one triterpene is less than 20% by weight.

4. The method as recited in claim 3 , wherein the at least one triterpene has a homogeneous particle size distribution.

5. The method as recited in claim 1 , wherein the specific surface area of the at least one triterpene is between 1 m 2 /g and 500 m 2 /g.

6. The method as recited in claim 5 , wherein the specific surface area of the at least one triterpene is between 10 m 2 /g and 100 m 2 /g.

7. The method as recited in claim 6 , wherein the specific surface area of the at least one triterpene is between 20 m 2 /g and 50 m 2 /g.

8. The method as recited in claim 1 , wherein the amount of the at least highly dispersed triterpene is more than 80% by weight.

9. The method as recited in claim 8 , wherein the proportion of the at least one highly dispersed triterpene is more than 90% by weight.

10. The method as recited in claim 1 , wherein the at least one triterpene has a proportion of more than 80% by weight betulin.
