No reproductive/developmentl toxicity reported from animal testing. Source: European Commission, Scientific Committee on Consumer Products (SCCP) 2007. Opinion on Acid Red 33C OLIPA n° C22. The Food and Drug Research Labs (1966) tested Dimethicone-containing fluids in oral studies to investigate possible atrophic changes in rat seminal vesicles. The test material was administered directly into the stomach of 10 male Sprague-Dawley rats at a dose of 3.3 ml/kg/day for 6 days. A control group received saline. Feed and water were available ad libitum. Rats were killed at the end of dosing and necropsy was performed. Final body weight and the weight of the seminal vesicles were measured. A Dimethicone sample (TX-158F) produced a significant reduction in the average seminal vesicle to body weight ratio but not in absolute organ weight. Two other Dimethicone samples had no adverse effect. Atlas Chemical Industries (1970) reported a study in which a medical grade antifoam compound (93% Dimethicone) was given orally to pregnant Wistar rats on gestational days (GDs) 6 to 15 at doses of 0.38, 1.20, and 3.80 g/kg/day. The highest dose was selected to represent 70 times the recommended clinical dose for the treatment of intestinal gas and 1000 times that recommended to treat peptic ulcers. A control group received tap water. Rats were examined by laparotomy on GD 20 at which time fetuses were removed from the uterus. Dams were killed and the ovaries were examined for corpora lutea. The authors concluded that Dimethicone at any dose did not induce significant differences in fetal viability at laparotomy, resorptions, average weight, and gross external, soft tissue, and skeletal anomalies. Siddiqui (1994) fed an antifoam compound (food-grade Dimethicone) to time-mated New Zealand white rabbits at concentrations of 0%, 0.5%, 1.0%, and 2.5% on GDs 6 to 19. Females were observed daily for clinical signs of toxicity. On gravid day 29, confirmed-pregnant females (20 to 22 per group) were evaluated for gestational outcome. Each live fetus was examined for external, visceral, and skeletal malformations. No overt signs of toxicity in the dams, and no statistically significant differences in feed consumption were observed between treated and control rabbits. No adverse effects were noted in mean maternal body weight or liver weight. The incidence of resorptions among the total fetal population was not altered by feeding the antifoam compound. Male and female pup weights were not affected by the maternal treatment. No significant treatment related adverse effects in the incidence of external, visceral, or skeletal abnormalities were observed.
