It is advisable not to use camphor, aniseed, pennyroyal, birch, wintergreen or sage essential oils when pregnant.
Avoid using deodorants or perfumes containing harmful chemicals such as silica, parabens, BHA, sodium lauryl sulphate, coal tars, petroleum by-products, propylene glycol, triclosan, polyethene/pegs and formaldehyde during pregnancy.
Select an aluminium free deodorant or perfume as studies have linked aluminium-based compounds to a higher risk of neurological diseases such as Alzheimer disease, gene instability and breast cancer.
Select unscented deodorants and perfumes instead of the fragrant ones. Fragrances usually have hormone-disrupting phthalates as an ingredient. Phthalates are not always listed on the label of the product you may wish to buy and even deodorants claiming to be phthalates-free may contain unknown phthalates substitutes that can cause potential harm during pregnancy.
