3. The lipstick formulation of claim 1, wherein (b) has a behenic acid content of from 35% to 60% by weight, based on a total weight of the hydrogenated rapeseed oil.
4. The lipstick formulation of claim 3, wherein (b) has a behenic acid content of from 42% to 54% by weight.
5. The lipstick formulation of claim 3, wherein a fatty acid with the second-highest content in (b) after behenic acid is stearic acid.
6. The lipstick formulation of claim 5, wherein (b) has a stearic acid content of from 30% to 44% by weight, based on a total weight of the hydrogenated rapeseed oil.
7. The lipstick formulation of claim 1, wherein the formulation comprises the lipid mixture in a concentration of at least 45% by weight, based on a total weight of the lipstick preparation.
8. The lipstick formulation of claim 1, wherein the formulation further comprises one or more waxes selected from beeswax, carnauba wax, candelilla wax, sunflower wax, rice wax, and hydrogenated castor oil.
9. The lipstick formulation of claim 8, wherein the one or more waxes are present in a total amount of from 0.05% to 15% by weight, based on a total weight of the formulation.
10. The lipstick formulation of claim 1, wherein the formulation further comprises one or more of cetyl palmitate, cetearyl alcohol, and shea butter.
11. The lipstick formulation of claim 10, wherein a total concentration of cetyl palmitate, cetearyl alcohol and shea butter in the formulation is from 0.05% to 15% by weight, based on a total weight of the formulation.
12. The lipstick formulation of claim 1, wherein the formulation further comprises one or more oils selected from castor oil, ethylhexyl stearate, coconut glycerides (INCI Cocoglycerides), olive oil, and sunflower oil.
13. The lipstick formulation of claim 1, wherein the formulation further comprises from 0.001% to 3% by weight of pigments, based on a total weight of the formulation.
14. The lipstick formulation of claim 13, wherein the formulation comprises one or more of silica, mica and titanium dioxide as pigments.
15. The lipstick formulation of claim 1, wherein the formulation further comprises hydrophilic constituents in a total concentration of from 0.001% to 1% by weight, based on a total weight of the formulation.
16. The lipstick formulation of claim 1, wherein the formulation further comprises one or more of water, panthenol, and glycerol as hydrophilic constituents.
17. The lipstick formulation of claim 1, wherein the formulation further comprises polyglyceryl-3 diisostearate.
18. The lipstick formulation of claim 17, wherein the formulation comprises polyglyceryl-3 diisostearate in a concentration of from 0.5% to 5% by weight, based on a total weight of the formulation.
19. The lipstick formulation of claim 1, wherein the formulation further comprises one or more flavorings (flavoring agents) and/or one or more perfumes.

Description
DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
Examples
(1) The examples shown below are intended to illustrate the present invention without restricting it. Unless indicated otherwise, all amounts shown, proportions, and percentages are based on the weight and the total amount/total weight of the preparations.
a) Lipid Mixture Examples
(2) The hydrogenated rapeseed oil was stirred into the octyldodecanol at 70° C. and cooled to 25° C. with stirring.
Example 1—Lipid Mixture
(3) TABLE-US-00001 (%) A Octyldodecanol 70 B Hydrogenated Rapeseed Oil 30 100
Example 2—Lipid Mixture
(4) TABLE-US-00002 (%) A Octyldodecanol 85 B Hydrogenated Rapeseed Oil 15 100
Example 3—Lipid Mixture
(5) TABLE-US-00003 (%) A Octyldodecanol 54 B Hydrogenated Rapeseed Oil 46 100
b) Examples for the Lipstick Formulation
(6) The lipid mixture and mixing ratio thereof from example 1 were now incorporated into the following stick formulation.
(7) TABLE-US-00004 1) Solid lip-balm stick (%) A Octyldodecanol 35 Hydrogenated Rapeseed Oil 15 B Ethylhexyl Stearate 15 Ricinus Communis Seed Oil 10 C Butyrospermum Parkii Butter 2 Cera Alba 11.5 Copernicia Cerifera Cera 0.5 Cetearyl Alcohol 3 Cetyl Palmitate D Polyglyceryl-3 Diisostearate 3 Perfume/Flavoring add to 100 Pigment add to 100 Persea Gratissima Oil add to 100 Simmondsia Chinensis Seed Oil add to 100 Neohesperidin Dihydrochalcone add to 100 UV filter add to 100 BHT add to 100 100
(8) Phase A is first heated to approximately 60-70° C., to melt the hydrogenated rapeseed oil into the octyldodecanol.
(9) In a separate beaker, phase B is now heated to 80-90° C.: on reaching this temperature, phase C is added and melted. If these phases and all high-melting waxes have clearly dissolved, they can be cooled down to approximately 60-65° C. Finally, on reaching this temperature, phase A is added, after which the further phase D, for example the emulsifier with the flavoring, may be incorporated.
(10) The mass can now be poured into a mold at approximately 60° C. It should then be allowed to cool down and should not be removed from the mold until fully solidified.
(11) TABLE-US-00005 2) Cosmetic stick (%) A Octyldodecanol 47 Hydrogenated Rapeseed Oil 10 B Ethylhexyl Stearate 7 Ricinus Communis Seed Oil 10 C Butyrospermum Parkii Butter 5 Candelilla Cera 0.5 Cera Alba 14 Copernicia Centera Cera 0.5 Cetearyl Alcohol 3 Helianthus Annuus Seed Cera 0.5 D Polyglyceryl-3 Diisostearate 2.5 Perfume/Flavoring add to 100 Pigment add to 100 Panthenol add to 100 UV filter add to 100 BHT add to 100 100
(12) This is produced in analogous manner to the solid lip-balm formulation.
