  • Publication number: 20180207277
    Abstract: The present invention provides a stable fat-soluble active ingredient composition, microcapsule and process for preparation and use thereof. The fat-soluble active ingredient composition comprises tocopherol, vitamin C palmitate and a fat-soluble active ingredient; wherein the weight ratio of tocopherol to vitamin C palmitate is 2-8:1, the weight ratio of a combination of tocopherol with vitamin C palmitate to the fat-soluble active ingredient is 7-13:100. The present invention obtains a novel antioxidant composition without hidden dangers for improving the stability of the fat-soluble active ingredient by screening a combination of antioxidants and adjusting their proportion and dose.

  • Patent number: 8697919
    Abstract: The invention discloses an intermediate 1-methoxyl-2,6,10-trimethyl-1,3,5, 9-undec-tetraene, and a preparation method and uses thereof. In the synthesis method for the current lycopene intermediate 2-pos double bond C-14 aldehyde (2,6,10-trimethyl-2,5,9-undecatriene-1-aldehyde), expensive methyl iodide, polluting dimethyl sulphide and dangerous strong base are needed, so that the method is hardly applied to industrial production. The invention provides a new compound 1-methoxyl-2,6,10-trimethyl-1,3,5,9-undec-tetraene, and pure 2-pos double bond C-14 aldehyde can be prepared by hydrolyzing and refining the compound. The synthetic route is simplified and the great suitability for industrial production is achieved.
