  • Poly(CPP-SA) anhydride as a reactive barrier matrix against percutaneous absorption of toxic chemicals
    Patent number: 9011830
    Abstract: The present invention relates to a protective agent suitable to protect the human skin against toxic materials, particularly against chemicals with nucleophilic sites. The active moiety is a polyanhydride derivative. The active transdermal retardant offers a barrier property and chemically and/or physically reacts with harmful chemicals to decrease percutaneous absorption. In the preferred embodiments, polyanhydride in its low molecular weight form reduced flux of nicotine and nitrofurazone significantly. Additionally, polyanhydride in its high molecular weight form prevented nicotine absorption and decreased nitrofurazone permeation dramatically. Moreover, the polyanhydride in its high molecular weight form reduced nitroglycerin flux to a lesser extent.
