What are the facts of the research?
As part of its commitment to the safe use of silicone, Dow Corning commissioned a two-year Combined Chronic/Carcinogenicity Study on D5 silicone. The study tested the effects of chronic inhalation of D5 at various levels of exposure for varying lengths of time, on male and female lab rats. None of the rats in the study were affected except for a small number of female rats in the test cell exposed at the highest possible exposure level for the longest possible time. Some of these rats developed pre-cancerous indicators, they did not develop cancer. The rats affected were the female rats exposed to the highest achievable vapor concentration of D5-160 ppm (parts per million)-six hours a day continuously for two years. By contrast, people who work in a dry cleaning plant are exposed at the lowest measurable vapor concentration of D5-1 ppm-during an eight-hour workday. What is important to understand is that the study was designed to test the potential effects of D5 as a chemical, not its
