Compositions comprising metathesized unsaturated polyol esters
Disclosed are petrolatum-like compositions that include metathesized unsaturated polyol esters. Also disclosed are emulsions that include metathesized unsaturated polyol esters. The petrolatum-like compositions may be used as substitutes for petroleum-based petrolatum. The emulsions may be water-in-oil or oil-in-water emulsions and may be suitable for a variety of end uses.
1. An emulsion comprising a dispersed phase and a continuous phase, wherein the dispersed phase comprises an unsaturated polyol ester composition, which comprises metathesis oligomers of unsaturated esters of glycerol and one or more stabilizers;
wherein at least 30 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis oligomers having four or more unit oligomers; and
wherein no more than 25 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis dimers.
2. The emulsion of claim 1 , wherein the emulsion is an oil-in-water emulsion.
3. The emulsion of claim 1 , wherein at least 40 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis oligomers having four or more unit oligomers.
4. The emulsion of claim 1 , wherein no more than 60 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis oligomers having four or more unit oligomers.
5. The emulsion of claim 1 , wherein no more than 50 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis oligomers having four or more unit oligomers.
6. The emulsion of claim 1 , wherein at least 5 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis dimers.
7. The emulsion of claim 1 , wherein at least 15 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis dimers.
8. The emulsion of claim 4 , wherein at least 5 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis dimers.
9. The emulsion of claim 4 , wherein at least 15 percent by weight of the unsaturated esters of glycerol in the unsaturated polyol ester composition are metathesis dimers.
10. The emulsion of claim 1 , wherein the metathesis oligomers have an iodine value (IV) of 100 or less.
11. The emulsion of claim 4 , wherein the metathesis oligomers have an iodine value (IV) of 100 or less.
12. The emulsion of claim 6 , wherein the metathesis oligomers have an iodine value (IV) of 100 or less.
13. The emulsion of claim 8 , wherein the metathesis oligomers have an iodine value (IV) of 100 or less.
14. The emulsion of claim 1 , wherein the unsaturated polyol ester composition has an iodine value (IV) that ranges from 5 to 100.
15. The emulsion of claim 4 , wherein the unsaturated polyol ester composition has an iodine value (IV) that ranges from 5 to 100.
16. The emulsion of claim 1 , wherein the one or more stabilizers comprise antioxidants, emulsifiers, or combinations thereof.
