Data from A. Formes and Colleagues Advance Knowledge in Siloxanes (Investigation of the silicone structure in breast implants using H-1 NMR)

July 2, 2014



By a News Reporter-Staff News Editor at Biotech Week -- Data detailed on Siloxanes have been presented. According to news reporting out of Cologne, Germany, by NewsRx editors, research stated, "Against the background of the scandal about low-grade silicone breast implants of the French manufacturer Poly Implant Prothese (PIP), several types of implants were examined using H-1 NMR spectroscopy. The intention was to classify an implant according to its silicone structure."

Our news journalists obtained a quote from the research, "Therefore, the certificated raw material of the American silicone producer Nusil Technology was analyzed and used as a reference. The list of tested implants consists of implants by PFM medical, PIP, Silimed, Rofil, Eurosilicone, Mentor, Perouse Plastie, Polytech, Nagor, CUI, and McGhan. In the H-1 NMR spectrum the signal of the vinyl group, which is used to cross link silicone rubbers, is visible. It is possible to differentiate between silicones which have a vinyl terminated end group and silicones whose vinyl group is located within the chain of the polymer. The two different types of the vinyl group are one mean to classify the implants. Other categories besides the type of vinyl include the relative amount of the remaining vinyl in the implant and the chemical structure of the material used for the production of the envelope."

According to the news editors, the research concluded: "With these characteristics the examined implants could be grouped into four types."
