Abstract
Processes for transesterifying wax esters. Implementations may include: providing a feedstock including wax esters, contacting the feedstock with a lipase, and catalytically transesterifying the wax esters in the feedstock with the lipase to form a transesterified product. An oxidative stability index (OSI) of the transesterified product may be greater than an OSI of the feedstock.
Claims20
A process for preparing enzymatically transesterified wax esters, the process comprising:
- contacting a feedstock with a lipase enzyme, wherein the feedstock comprises feedstock wax esters and an antioxidant, wherein the feedstock wax esters comprise jojoba wax esters and hydrogenated jojoba wax esters, and wherein the feedstock has an oxidative stability index;
- and
- reacting the jojoba wax esters and the hydrogenated jojoba wax esters in the-feedstock using the lipase enzyme to yield a product comprising transesterified jojoba wax esters, transesterified hydrogenated jojoba wax esters, and the antioxidant, wherein the product has a product oxidative stability index that is greater than, equal to, or less than the oxidative stability index of the feedstock, wherein the product does not contain a free fatty alcohol.
A process for preparing enzymatically transesterified wax esters, the process comprising:
- contacting a feedstock with a lipase enzyme, wherein the feedstock comprises feedstock wax esters and an antioxidant, wherein the feedstock wax esters comprise jojoba wax esters and hydrogenated jojoba wax esters, and wherein the feedstock has an oxidative stability index;
- and
- reacting the jojoba wax esters and the hydrogenated jojoba wax esters in the-feedstock using the lipase enzyme to yield a product comprising transesterified jojoba wax esters, transesterified hydrogenated jojoba wax esters, and the antioxidant, wherein the product has a product oxidative stability index that is equal to the oxidative stability index of the feedstock, wherein the product does not contain a free fatty alcohol.
