Alarming Findings from Indian Universities on Sanitary Pads Safety

Recent research conducted by scientists at Lovely Professional University (LPU) in Phagwara, Punjab, and Central University of Punjab in Bathinda has shed light on a pressing public health concern: the presence of harmful chemicals in sanitary pads commonly used across India. This collaborative study, published in the journal Environmental Science and Pollution Research, analyzed five popular brands and detected elevated levels of volatile organic compounds (VOCs), dioxins, furans, phthalates, and chlorine—substances linked to serious health risks including endocrine disruption and potential cancer development.

The vaginal mucosa, being highly permeable, allows these chemicals direct entry into the bloodstream, amplifying exposure risks for millions of women who use sanitary pads for an average of 1,800 days over their reproductive lifetimes. With India's menstrual hygiene market booming amid government initiatives like Swachh Bharat, these revelations underscore the urgent need for safer products and stricter regulations.

Lead researchers Binay Kumar, Jandeep Singh, and Harminder Singh from LPU's School of Chemical Engineering and Physical Sciences, alongside Sunil Mittal from Central University of Punjab's Department of Environmental Science and Technology, employed gas chromatography mass spectroscopy (GCMS) to quantify contaminants. Their work highlights how Indian-manufactured pads often exceed chemical thresholds seen in products from the USA, Europe, and Japan.

Chemicals Identified: Phthalates, Dioxins, and VOCs Under the Microscope

The study pinpointed specific toxins: total chlorine ranged from 170 to 460 parts per million (ppm), dioxins from 0.244 to 21.419 picograms per gram (pg/g), furans from 0.07 to 0.563 pg/g, acetone (a VOC) from 351 to 429 ppm, isopropyl alcohol from 125 to 184 ppm, and toluene from 2.91 to 3.21 parts per billion (ppb). Phthalates like di-n-butyl phthalate (DBP) and di(2-ethylhexyl) phthalate (DEHP) measured 57.3–127.8 and 146.2–188.5 micrograms per gram, respectively.

Phthalates, used as plasticizers for flexibility, are endocrine-disrupting chemicals (EDCs) that mimic hormones, potentially leading to reproductive disorders. Dioxins and furans, byproducts of chlorine bleaching, are persistent organic pollutants (POPs) classified as carcinogenic by the World Health Organization (WHO). VOCs like acetone and toluene can cause irritation and long-term organ damage.

Complementing this, a 2022 investigation by NGO Toxics Link tested 10 brands (including Whisper and Stayfree) and found 12 phthalate types and multiple VOCs, even in 'organic' variants. While not university-led, it aligns with academic findings, reinforcing the prevalence of these contaminants.

Health Implications: Cancer Risks and Beyond

Daily exposure doses (DED) from the LPU-Central University study exceed safe limits for dioxins—around three times the tolerable daily intake (TDI) of 0.7 pg TEQ/kg body weight/day—raising alarms for chronic effects. DBP exposure hit 4.24–9.47 μg/kg-bw/day, surpassing reference doses linked to developmental toxicity.

Dioxins are probable human carcinogens, associated with breast, ovarian, and cervical cancers. In India, where two-thirds of cervical cancer cases link to poor menstrual hygiene per some reports, this is particularly concerning. Phthalates correlate with infertility, endometriosis, and hormone-related cancers; VOCs contribute to cardiovascular issues and respiratory problems.

Women experience immediate symptoms like rashes, allergies, and infections, but long-term risks include toxic shock syndrome (TSS) and disrupted menstrual cycles. Vulnerable groups—adolescents and rural women using pads daily—face heightened threats amid low awareness.

University experts emphasize cumulative exposure: over decades, these micro-doses accumulate. Rate professors like those at Central University of Punjab on Rate My Professor to connect with leading voices in toxicology.

Regulatory Landscape and Gaps in India

India's Bureau of Indian Standards (BIS IS 380:2014) mandates absorbency tests but ignores chemical safety, classifying pads as non-medical items exempt from ingredient labeling. Unlike the EU's REACH or US FDA scrutiny, no routine testing for EDCs exists.

The study calls for mandatory disclosure, toxicity assessments, and bans on high-risk chemicals. Government schemes like Pradhan Mantri Bharatiya Janaushadhi provide affordable pads, but quality oversight lags.

Indian universities are stepping up; Lovely Professional University's research exemplifies how higher education drives policy change. Aspiring researchers can find research jobs in public health at top institutions.

Environmental Toll: Plastic Waste from Menstrual Products

Beyond health, each pad contains plastics equivalent to 33,210 tons annually in India—exacerbating landfills and microplastic pollution. Non-biodegradable super-absorbents persist for centuries, leaching chemicals into soil and water.

Universities advocate sustainable alternatives; IITs and others pioneer biodegradable innovations. Check top research breakthroughs from Indian universities for eco-friendly solutions.

Safer Alternatives: What Women Can Choose

Menstrual cups, cloth pads, and organic cotton options minimize exposure. Certified biodegradable pads like Anandi Eco+ (tested by government labs) offer promise. Transition tips: start with hybrid use, ensure sterilization.

Stakeholder Perspectives: Industry, Government, and Academia

Industry claims levels are safe, but academics counter with exposure data. Gynaecologists recommend fragrance-free pads. Government responds via awareness drives, yet enforcement gaps persist.

Central University of Punjab's Sunil Mittal notes, 'Higher chemical loads in Indian pads demand immediate action.' Such insights position universities as policy influencers.

Future Research Directions from Indian Academia

Ongoing studies at IITs explore nano-materials for safe absorbency. Calls grow for longitudinal health impact research. With 355 million menstruating women, university collaborations are key.
