Cotton Pads and Plastic-Free Options: A Buying Guide

Did you know a conventional disposable pad can contain up to 90% plastic, even though it looks like “just fabric” from the outside? If you’re looking to cut down your contact with plastic and possible added chemicals without giving up something as simple as a pad, cotton pads are one of the easiest swaps to make. We cover what to check before buying and what truly plastic-free options actually exist.

Why choose cotton pads over conventional ones

Standard disposable pads usually combine cellulose with layers of polyethylene or polypropylene (the “plastic” that makes them waterproof) and, in some cases, synthetic super-absorbent gels. A certified organic cotton pad, by contrast, skips those plastic layers against the skin, reducing both the waste generated and the friction of synthetic materials on an especially sensitive area. If you want the full context on what conventional pads actually contain, we break it down in our comparative analysis of pad and tampon brands.

What to check on the label before buying

Not everything marketed as “cotton” is 100% cotton. Before buying, check these four points:

• Actual composition: look for “100% organic cotton” in the layer against the skin, not just “with cotton” (a partial mention doesn’t guarantee no plastic in the other layers).
• OEKO-TEX Standard 100 certification: guarantees the fabric has been tested and is free of substances harmful to health, a demanding standard that goes beyond minimum regulatory requirements.
• No chlorine or bleach: chlorine bleaching can leave dioxin residue; organic cotton doesn’t need this process to look clean.
• No added fragrance: perfumes are a common cause of irritation in the intimate area; a good cotton product doesn’t need them.

What the evidence says about chemicals in menstrual products

A study published in 2025 in the journal Environment International analyzed the chemical composition of 64 intimate and menstrual hygiene products — including tampons, pads, cups, and sponges from manufacturers in the EU, US, and China — looking for potentially hazardous substances. The analysis detected 55 distinct compounds in the extraction phase (phthalates, siloxanes, volatile organic compounds, fragrances, and plastic additives), but when simulating real-use conditions, 65% of those compounds weren’t released in detectable amounts. Of the 19 compounds that did migrate under real-use conditions, most were fragrances and phthalates, at levels the authors describe as low (parts per billion to parts per million). The researchers’ own conclusion is clear: most potentially hazardous substances present in these products aren’t detected under real-use conditions, but exposure to phthalates and fragrances remains possible. It’s exactly that possibility that justifies choosing certified, fragrance-free products when an alternative exists, like OEKO-TEX organic cotton. You can check the full study on PubMed.

Disposable cotton pads vs. reusable ones: the real differences

Within “cotton” options, there are two very different categories. Disposable cotton pads replace the plastic layers with biodegradable plant-based materials, but they’re still single-use: they reduce skin contact with plastic, though they still generate waste every cycle. Reusable cotton pads (cloth, with a button closure) are washed and used for years, cutting both waste and recurring cost. The natural next step within this same philosophy — pad-level comfort, zero waste, zero plastic — is organic cotton period panties: absorption is built into the fabric itself, with nothing to place or remove separately.

Why the industry doesn’t talk much about this option

A pack of conventional pads gets bought, used within a few days, and restocked the following month, month after month, year after year: it’s a constant-repurchase business. Organic cotton period panties, on the other hand, are bought once and last for years with proper care, which partly explains why they don’t get the same advertising investment as a product you have to replenish every 28 days. It isn’t a conspiracy theory, it’s simple business logic: whoever sells something that lasts for years has far less incentive to shout about it than whoever sells something that runs out every month.

How to care for reusable cotton pads

If you go with reusable cotton pads, care is simple: rinse with cold water right after taking them off (hot water sets blood into the fiber and makes cleaning harder), then they can be machine washed with the rest of your laundry at a moderate temperature, without fabric softener, which reduces cotton’s absorbency over time. Air dry them whenever possible to better preserve the fiber. It’s the same care principle we apply to organic cotton period panties: a rinse, a normal wash, and ready for the next cycle, for years.

Many women start by combining reusable cotton pads for light-flow days with a menstrual cup for heavy days; if you’d rather go straight for the convenience of not having to place or remove anything, the Sileu Rose is the cup designed to make that leap simple from the very first cycle.

How much you save (and how much plastic you avoid) by switching

The average user spends between €5 and €10 a month on disposable pads and tampons, which adds up to €60-120 a year, a figure that repeats every year across decades of fertile life. Organic cotton period panties, with basic wash care, pay for themselves within a few months and stay useful for years. In terms of waste, each disposable pad can take hundreds of years to break down because of its plastic components; replacing even part of your cycle with reusable options directly and measurably reduces that impact. We go deeper into the full environmental impact in your period’s carbon footprint: the impact of pads and tampons and in living without plastic: menstruating without harming the oceans.
