Study detects phthalates in six Nigerian sanitary-pad brands, prompting calls for stronger monitoring and safer menstrual products


Concerns over the safety of commercially available sanitary pads in Nigeria have resurfaced following the publication of a study that detected phthalates in six brands of sanitary pads marketed in the country.


The study, published in Scientia Africana in February 2026, examined six Nigerian sanitary-pad brands and identified 12 different phthalate compounds. Diisobutyl phthalate (DiBP) recorded the highest concentrations among the compounds detected in the tested samples.


The researchers said the estimated daily exposure doses recorded in the study were higher than those reported in comparable studies from other countries. They noted that the findings raise health concerns and called for routine regulatory monitoring and the development of alternative technologies to reduce or eliminate phthalate exposure from sanitary products.


Phthalates are chemicals used in various consumer products, and some members of the chemical group have been studied for their potential endocrine-disrupting effects. However, detecting a chemical in a product does not, by itself, establish that normal use of the product will cause illness.


The findings have nevertheless generated renewed public discussion about menstrual-product safety, affordability and regulatory oversight, with some consumers calling for greater transparency about the materials used in sanitary pads.


The study also highlights the need for further research and independent testing to determine the extent of chemical exposure associated with sanitary products used by women and girls in Nigeria.


Health professionals generally advise consumers experiencing persistent irritation, pain, unusual discharge or other concerning symptoms during menstruation to seek medical attention rather than assuming that a particular product or chemical is responsible.


The researchers recommended stronger routine monitoring of sanitary products and further research into safer alternatives for menstrual hygiene.
