  • Method for encapsulation, remediation and recovery of spilled oil
    Patent number: 7794595
    Abstract: Diacylglycerol PEGs (DAG-PEGs) are used remediate oil contaminations. DA-PEGs encapsulate the oil into lipsomes in an aqueous environment. The lipsomes sequester the oil from causing damage.
