  • Patent number: 12516267
    Abstract: A wax composition is disclosed, comprising at least 70% triacylglycerols, wherein the triacylglycerols comprise 0.5 to 50 wt. % of C22 fatty acid. A method of preparing a wax composition is disclosed. A candle comprising the wax composition and a method of preparing a candle are also disclosed.
    Type: Grant

  • Patent number: 9809618
    Abstract: A new process for enriching triterpene esters comprising: providing a mixture comprising a non-distilled vegetable oil and/or a non-distilled vegetable fat, further comprising triterpene esters, performing a mild transesterification with a lower alcohol, removing lower alcohol esters by deodorization, physical refining, evaporation or distillation, and recovering the remaining fraction rich in triterpene esters. Triterpene esters enriched with the method as well as uses of the same are also provided. One advantage is that it is a more economically viable way of achieving higher concentration of triterpene esters. There is both the chance to fully keep the natural distribution of triterpene esters but in the other end also to replace the natural level of cinnamic and acetic acids-triterpene esters with a high level of long fatty acid triterpene-esters.

  • Publication number: 20150166930
    Abstract: The present invention provides a process for lowering the amount of esters of 2- and 3-MCPD in refined triglyceride oil, wherein said oil prior to entering the process has been treated with one or more refining steps and wherein said oil comprises triglycerides of fatty acids having a carbon chain length of C12-C24 in an amount of at least 50% of the total triglyceride content, the process comprising the steps of: blending the oil with a base and heat treating the oil while passing steam through the oil at reduced pressure, keeping the degree of interesterification in the product from the process below 60%.
