Dimethicone while Breastfeeding

CAS Number: 9006-65-9

Dimethicone is a fluid type of silicone with a methyl as organic group radical. Silicones are polymers of silicon tied to oxygen atoms with high molecular weight (see information on silicone and dimethicone). Dimethicone is water repellent and it is used in creams, dressings for skin protection and pediculicides. An activated form of Dimethicone is Simethicone that is used for treatment of flatulence (see info on Simethicone) At latest update, relevant published data on excretion into breast milk were not found. Because it is not absorbed through the skin or orally along with a high molecular weight, excretion into breast milk in significant amount or absorption by the infant gut is highly unlikely.

Octinoxate and Breastfeeding

Octinoxate (Octylmethoxycinnamate) has been detected in human urine, blood and breast milk and is known for moderate risk of skin allergy. Some studies suggest that Octinoxate has estrogen like effects however less than 1% skin penetration has been found in human laboratory studies. As not much study has been done on effects of Octinoxate during breast feeding its recommended to use safe alternatives.

Octyl Methoxycinnamate (OMC) is a frequently used UV-filter in sunscreens and other cosmetics. Octinoxate can be systemically absorbed after skin application, being found in the deeper layers of the stratum corneum as well as urine, plasma, and breast milk. The mean maximum plasma concentration detected after application of 2mg/cm2 sunscreen was 7ng/mL in women and 16ng/mL in men. FDA study found blood levels 13 times above cutoff for systemic exposure.

Several studies indicated that OMC acts as an endocrine disruptor due to the ability to interfere with endocrine system at different levels. In humans OMC exposure has minor, but statistically significant effects on the levels of testosterone and estradiol. Moreover, some studies suggested that OMC can interact with the hypothalamo-pituitary-thyroid (HPT) axis.

Moreover, a study of offspring of dams treated with OMC (500�1000 mg/kg/day) showed sex-dependent behavioral changes, namely decreased motor activity in females, but not in males, and improved spatial learning in males, suggesting that OMC can affect neuronal development, however the doses used in these experiments were extremely high, not relevant to possible human exposure.

Octisalate and Breastfeeding

Octyl salicylate is an oil soluble chemical sunscreen agent that absorbs UVB radiation. It does not protect against UVA. Octyl salicylate is used to augment the UVB protection in a sunscreen. Salicylates are weak UVB absorbers and they are generally used in combination with other UV filters

Octisalate rarely causes allergies in tropical usage. Not much study has been done on effects of topical usage of Octisalate during breast feeding however it is known to penetrate the skin hence it�s better to use other alternatives.

FDA study found blood levels 10 times above cutoff for systemic exposure, skin penetration in lab studies has been observed
