What we know about using Peg-40 Hydrogenated Castor Oil while pregnant or breastfeeding
Limited information available.
Feeding studies for the assessment of reproductive and teratogenic effects of PEG-40 hydrogenated castor oil were conducted in pregnant S-D rats. One group (30 rats) was given 50,000 ppm and another 27 rats were given 100,000-ppm PEG-40 hydrogenated castor oil from gestational day 0 to gestational day 20, while another 2 groups of untreated control were raised. Pregnant animals were monitored and assessed for signs of toxicity during gestation, and were sacrificed at gestational day 20 for fetal examination. Examinations of the mother and fetuses did not reveal any signs of toxicity. Although resorption and malformations/anomalies were found in some animals in the highest dose group, similar changes were also found in the control group, showing no significant differences. Thus, the researchers conducting the study could not conclude teratogenicity for PEG-40 hydrogenated castor oil. Studies were also conducted in 4 groups of pregnant NMRI mice using 5,000 ppm (25 mice) and 10,000 ppm (31 mice) PEG-40 hydrogenated castor oil from day 6 to 15 of gestation; the other 2 groups were raised as controls. During the study, no significant maternal or fetal toxicity effects were found, and some malformations in fetuses in the treated groups were also comparable to the control groups (Table 2) (19).
General safety info about Peg-40 Hydrogenated Castor Oil from CIR
The Cosmetic Ingredient Review Expert Panel considered the safety of PEGylated oils, which function primarily as surfactants, in cosmetic products. The Panel reviewed relevant animal and human data provided in this safety assessment, and concluded that the 130 chemically related PEGylated oils were safe as cosmetic ingredients in the present practices of use and concentration when formulated to be non-irritating.
