What we know about using Cetyl Dimethicone while pregnant or breastfeeding

Limited information available.

Dimethicone was tested in numerous oral-dose (using rats) and dermal-dose (using rats, rabbits, monkeys) reproductive and developmental toxicity studies.1 In an oral study with rats, 3.3 mL/kg/d Dimethicone was administered directly to the stomach for 6 d. Males treated with 1 of 3 Dimethicone samples (no further details provided) had significantly decreased body weight and/or decreased testes or seminal vesicles weights. No treatment-related adverse findings were noted in pregnant females or fetuses, dosed orally, via diet, and dermally. In an intergenerational study, a motor oil containing an unspecified amount of Dimethicone was applied undiluted in doses of 0.1, 0.4, and 1.5 mL/kg, to the shaved backs of the parental (P1) and first generation (F1) of Sprague-Dawley rats, daily for an 8-wk premating period, 3-wk mating period, and throughout gestation and lactation. Mortality was significantly increased on day 0 in the 0.4 mL/kg group, and absolute testes weight was significantly reduced in the adult F1 male rats of the 1.5 mL/kg group, beginning wk 7, but the relative testes to body weight ratio was not significantly different from controls. No additional developmental and reproductive toxicity studies were found in the published literature, and unpublished data were not submitted.

General safety info about Cetyl Dimethicone from CIR

The Expert Panel for Cosmetic Ingredient Safety assessed the safety of 30 Dimethicone, Methicone, and substituted-Methicone polymers; 20 of these ingredients were previously reviewed by the Panel, and 10 are reviewed herein for the first time. Most of these ingredients are reported to function as skin and hair conditioning agents. The Panel reviewed relevant new data, including frequency and concentration of use, as well as exposure type, and considered data from the previous report. The Panel concluded that these ingredients are safe in cosmetics in the present practices of use and concentration as described in this safety assessment when formulated to be non-irritating to the skin and eye.
