Cosmetic products to fight the bad smelling of sweat (deodorant) or prevent perspiration (antiperspirant). They may contain alcohol, aluminum, sodium or magnesium (talc) salts, bactericides such as triclosan, perfumes and fragrances such as various synthetic musks, phthalates (BBP, DBP, DEHP, DEP), bisphenol A (BPA), parabens, glycerin , Allantoin, waxes, dimethicone and other emollients, emulsifiers and excipients.
In addition to polluting the environment, several of these compounds are endocrine disruptors, some with estrogenic capacity (Lange 2014) with abundant controversy about its carcinogenic capability.
Transcutaneous absorption is possibly very limited, but triclosan, parabens and synthetic musk have been found in breast milk related to the use of deodorants. (Reiner 2007, Potera 2007, Wang 2011, Zhang 2011, Toms 2011, Yin 2012, Zhang 2015, Hines 2015)
Health authorities and some authors (Food & Drug Administration, National Cancer Institute, Namer 2008) consider that despite adverse effects of deodorants on health, more specifically a relationship with cancer, have not been proven yet (Mirick 2002, Allam 2016), further research is needed on clarifying whether deodorant compounds may accumulate in breast tissue and can be a cause of illness. (Darbre 2005, NCI 2008, Allam 2016)
Some authors believe that the aluminum content in deodorants should be restrained (Pineal 2014). Aluminum levels in breast milk were similar, regardless of the type of deodorant used by mothers: whether with or without aluminum. (Rochman 2021)
Although there are no scientific reports to prove it, experts believe that perfume contained in deodorants could alter the olfactory ability of recognition in the newborn and infant which is important on the process of latching-on the breast. (AEP Breastfeeding Committee, 2012)
Until more information is available, a moderate use of the deodorant may be advisable during breastfeeding, avoiding those containing bisphenol, parabens and fragrance or excessive perfume, and do not apply them close to the breast and/or on the breast to prevent them being ingested by the infant.
Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
Thank you for helping to protect and promote breastfeeding.
