  • Reduced-cloud-point clarified neem oil and methods of producing
    Patent number: 5626848
    Abstract: A clarified neem oil having a cloud point below 13.degree. C. exhibits reduced phytotoxicity. Treatment of crude neem oil with a dilute aqueous basic solution or with an enzyme having lipid-degrading activity yields a clarified neem oil having acceptably low phytotoxicity. The methods are advantageous because they reduce or eliminate the waste stream of waxy by-product generated using existing methods for clarifying crude neem oil.
