UFS Study on Sanitary Pads and Liners: What You Need to Know
The recent scientific study published in Science of the Total Environment (2026) by researchers from the University of the Free State (UFS) has confirmed what many women feared: several sanitary pads and liners sold in South Africa contain high levels of Endocrine Disrupting Chemicals (EDCs).
The study found phthalates, bisphenols, and parabens in nearly 100% of the liners tested. These chemicals are linked to cancer, hormonal imbalances, and reproductive health issues.
What Exactly Was Tested in the UFS Study?
According to the published research, “a total of 20 endocrine-disrupting chemicals (EDCs), including nine phthalates, five parabens, and six bisphenols were analyzed in 16 commercially available sanitary pads and 7 commercially available panty-liners from a popular retail store in South Africa… varying in price (R17.00–R32.00 for a standard packet).”
At GENTLE DAY®, we don’t just read these reports—we verify our safety against them. We want to provide you with a side-by-side comparison of what the UFS study found in common brands versus what our independent lab tests show for GENTLE DAY®.

|
Chemical Group |
What the UFS Found in Local Brands |
GENTLE DAY® (AITEX Lab Result) |
|
Phthalates |
High detection (75-100%). Used to make plastics flexible. |
NOT DETECTED. Our AITEX report (2025OK3660) proves 0% harmful phthalates. |
|
Bisphenols (BPA/BPS) |
Frequently detected in pads. Linked to hormonal disruption. |
NOT DETECTED. Our products are certified BPA/BPS free. |
|
Parabens |
Present in many liners as preservatives. |
NOT DETECTED. Gentle Day uses no harmful chemical preservatives. |
|
Heavy Metals |
Traces of Lead, Cadmium, and Chromium in "period packs." |
NOT DETECTED. Our OEKO-TEX® testing covers 10 heavy metals; all are below detection limits. |
Why Gentle Day® is Different
The researchers at UFS noted that long-term, repeated dermal contact with these chemicals is a serious health concern. Because you wear these products for hours, every single month, for decades—purity is non-negotiable.
1. The OEKO-TEX® Standard 100 (Product Class II)
Our latest AITEX (Spain) report confirms that every part of a GENTLE DAY® pad—from the top sheet to the adhesive—meets the strict requirements for products in direct contact with skin. This is a voluntary, expensive, and rigorous annual audit that most conventional brands simply do not undergo.
2. GOTS Certified Organic
Our GENTLE DAY® tampons are 100% organic cotton. This certification ensures that no pesticides were used in the fields and no toxic chemicals were used during manufacturing.
3. pH Neutral and Skin Friendly
The UFS study focuses on internal health, but external irritation is just as important. Our tests confirm that our products maintain a skin-friendly pH, preventing the rashes and discomfort often associated with chemical-laden pads.
A Note to Our Partners and Pharmacists
We provide these laboratory reports because transparency is the foundation of healthcare. When you stock GENTLE DAY®, you are offering your customers a product that has been scientifically cleared of the very toxins highlighted in the latest South African research.
You Deserve Better
The UFS study is a wake-up call for the industry, but it doesn't have to be a source of fear for you. You have a choice. You can choose a brand that prioritizes your endocrine health over profit margins.
Your health is our foundation. Period.
