Review: sanitary pads—composition, regulation, and ongoing research to address associated challenges
AI summary Read the abstract
Sanitary pads are complex products containing a range of synthetic materials, including plastics and chemical additives, yet they remain largely underregulated for intimate-use safety. This review examines the composition of commercially available sanitary pads, the regulatory frameworks governing them, and emerging research on potential health implications of prolonged exposure to their components. Growing awareness of plastic and chemical exposure through menstrual products has prompted calls for greater transparency and stricter safety standards.
Abstract Menstrual health management (MHM) plays a crucial role in women’s well-being and empowerment; yet, it remains a pressing challenge in many parts of the world. The transition from traditional methods of managing menstruation, such as using rags or other makeshift materials, to the use of disposable sanitary pads has significantly impacted women's lives. However, there are many people, especially in the Global South, that still battles with a lack of access to proper MHM and the application of water, sanitation and hygiene facilities (WASH). In many developing countries, women have historically relied on improvised materials like rags, leaves, or old clothing to manage their menstruation. These methods often result in poor hygiene practices, discomfort, and an increased risk of infection. The introduction and widespread availability of disposable sanitary pads have revolutionized menstrual health management in the Global North, mainly by providing a convenient and hygienic alternative. Disposable sanitary pads offer absorbency, leak protection, and odour control, enhancing women’s comfort and confidence during menstruation. However, challenges persist in ensuring the sustainable production and disposal of disposable sanitary pads. The environmental impact of disposable sanitary pads, including their non-biodegradable nature and plastic waste, raises concerns about long-term sustainability. Also, several voices have gone up against the use of phthalates and other harmful chemicals found in these products which are considered harmful to the female reproduction system. While efforts are underway to develop eco-friendly alternatives and promote proper waste management practices, MHM still has a long way to go. In this article, we discuss the history, composition, the various issues of their use, and the latest developments in the research and manufacture of disposable sanitary pads. We show with examples from the Global South, from countries like South Africa, Uganda, and India, that much is yet to be done to provide access to all due to costs, and that safety and the environment are not the highest priority when selecting a sanitary product. We conclude with suggestions for future research and development of sanitary products. Graphical Abstract

This systematic review examined the lifecycle of disposable menstrual pads, finding that plastic pollution, chemical exposures from phthalates and PFAS, and menstrual poverty collectively make disposable absorbers a major intersectoral public health and environmental challenge requiring stronger regulation and sustainable alternatives.
A planetary health perspective on menstruation: menstrual equity and climate action
AI summary Read the abstract
This planetary health review highlights how conventional menstrual hygiene products generate significant plastic waste and contain potentially harmful chemicals, while many people worldwide lack adequate access to menstrual products. Reusable and sustainable alternatives could simultaneously address menstrual equity and reduce environmental plastic pollution.
Morphological and Performance Assessment of Commercial Menstrual and Incontinence Absorbent Hygiene Products
AI summary Read the abstract
Analysis of fifteen commercial absorbent hygiene products found that most contain non-biodegradable plastics, with limited sustainable substitutes available for superabsorbent polymers, though structural design changes could reduce total plastic content. Given that disposable hygiene products contribute to microplastic pollution in landfills and waterways, this work identifies concrete pathways for reducing a significant but underexamined plastic waste stream.

This review discusses how plastic-heavy disposable sanitary pads contribute to microplastic pollution and environmental waste, and evaluates natural material alternatives including cotton, bamboo, and plant-based polymers that could reduce the environmental footprint of menstrual hygiene products.
Environmental impact of plastic-based menstrual products in Kenya
AI summary Read the abstract
Most disposable pads and tampons are made of plastic and can contain harmful chemicals, including hormone-disrupting substances, that add up to serious environmental waste over time. A survey of nearly 1,000 Kenyan schoolgirls found that most are already aware of and concerned about this plastic waste problem, suggesting real demand for safer options like menstrual cups, reusable pads, or period underwear. This matters because switching to reusable products could cut down on both plastic pollution and potential chemical exposure from single-use items.
