Have you ever experienced irritation or itching from using regular pads or tampons? We might have a solution! The Louloucup organic cotton period panties offer a healthy, safe, comfortable, and eco-friendly alternative for all menstruating women.


Made from GOTS and OEKO-TEX® certified organic cotton, this feminine intimate protection eliminates risks associated with chemicals like phthalates or pesticides found in disposable products, while also preventing intimate imbalances.


Breathable, hypoallergenic, and reusable, period underwear reinvents your menstrual hygiene with absolute comfort and stylish design. Ethical period lingerie is a true revolution for both teens and women.
Intimate well-being, eco-friendly commitment, sustainable savings, reduced mental load—today we’re talking about composition, materials, fabrics, certifications, and product features.

I. The composition of period underwear: a top priority

When you start using washable period underwear, the very first thing to check is definitely the fabric composition. Because yes, buying a set of washable, reusable menstrual products is great, but getting a set made with healthy materials and ethical manufacturing is even better! We avoid tampons and pads with dangerous and harmful ingredients for a reason—so don’t just buy anything!

🌸 The not-so-glamorous side of disposable period products

Have you ever read the ingredient list on a package of pads or tampons? The intimate area is especially vulnerable, easily absorbing whatever it comes into contact with. Yet, many disposable period products contain unexpected substances: herbicides, endocrine disruptors, chlorine derivatives, phthalates, petrochemical by-products, and more.


Disposable period products, though essential, contain concerning ingredients. Chlorine bleaching produces dioxin residues, which are classified as endocrine disruptors or carcinogens. Phthalates, found in plastics, disrupt the hormonal system. There are also pesticides like glyphosate. Finally, synthetic fragrances—often undeclared—can cause irritation.

Chlorine and dioxins from bleaching,

Pesticides (glyphosate) from conventional cotton,

Phthalates and plasticizers,

Fragrances and odor neutralizers.

These substances increase the risk of allergies, intimate dryness, and even toxic shock syndrome (TSS) with tampons.


Fortunately, in recent years, several healthy, effective, and safe alternatives with clean ingredients have become popular: menstrual cups, period swimwear, and period panties.

🌸 Organic cotton: the healthy, gentle answer for your body and the planet

Organic cotton changes everything. Grown without pesticides, this natural material is gentle on both your body and the environment. It’s hypoallergenic, reducing the risk of yeast infections or irritation. Its breathability prevents moisture buildup, making it an ideal choice for your period routine.


From an environmental perspective, organic cotton uses less water and helps protect biodiversity, unlike conventional cotton, which accounts for 16% of global pesticide use. By choosing washable organic cotton underwear, you reduce plastic waste and adopt a long-term reusable solution.

Did you know? At Louloucup, all our panties are OEKO-TEX® Standard 100 certified, guaranteeing the absence of harmful substances. All our panties are lined with GOTS-certified organic cotton on the inside, ensuring maximum safety for your skin, your intimate health, and the planet.


By combining health, comfort, and sustainability, the organic cotton period underwear stands out as a truly eco-friendly, practical, and hygienic solution. It’s a modern alternative that meets today’s challenges of sustainability and women’s wellness.

II. Louloucup: the guarantee of healthy, comfortable, and committed period underwear

GOTS-certified organic cotton: our secret for unmatched softness

Louloucup period panties use GOTS-certified organic cotton. This standard ensures the cotton is grown without chemical pesticides, synthetic fertilizers, or GMOs, preserving biodiversity and soil fertility.


By the way, what is the GOTS label?


The GOTS label oversees the entire production chain. From fiber to finished product, every step is monitored to reduce environmental impact and protect workers’ rights. Renewable energy is used, and wastewater is treated before being released. The result: an exceptionally soft fabric, perfect for sensitive skin.


Louloucup offers a natural alternative to conventional period products. Organic cotton hugs your skin without irritation, avoiding itching or redness. Unlike the harsh chemicals in disposable tampons or pads, it maintains intimate balance without sacrificing comfort. Plus, it prevents excess sweating and dampness.

OEKO-TEX® Standard 100 certification: your peace of mind

Each component of our underwear is tested according to the OEKO-TEX® Standard 100 label. Over 1,000 harmful substances, such as endocrine disruptors, heavy metals, or azo dye residues, are systematically excluded. Even the elastics and seams are analyzed.

Unlike disposable products, which are often made with plastics or bleaching agents, Louloucup models eliminate any chemical risk. Rigorous testing confirms they are completely safe for intimate health. For example, formaldehyde, a common irritant in industrial textiles, is strictly prohibited.

With double GOTS and OEKO-TEX® certification, Louloucup combines well-being and sustainability. Wearing panties knowing they respect your body and the strictest standards—from cotton farming to recycled packaging—is pure pleasure!

More than just underwear: a choice for your comfort, your health, and the planet.

By choosing washable underwear, you’re making a real difference for the planet—a choice that matters. You avoid accumulating non-recyclable waste (wrappers and products) month after month.

One piece replaces up to 150 pads per year, reducing your carbon footprint. Did you know a tampon takes 6 months to break down?

To sum up: Louloucup menstrual panties are OEKO-TEX® Standard 100 certified and all lined with GOTS-certified organic cotton. Three guarantees:

for comfort (softness, breathability),

Good for your health (ethical, clean ingredients, hypoallergenic),

eco-friendly (washable, zero waste, reusable for many years).

No more compromising between comfort, health, and the planet: Louloucup represents a gentle revolution, blending textile innovation with ecological commitment.

In short, each pair of underwear becomes a wellness ally and a step toward more responsible consumption. Choosing organic cotton is an investment in a sustainable solution that's healthy for you and respectful of the environment.

FAQ: Organic cotton underwear

What’s the best material for period underwear?

Organic cotton is the perfect material for period underwear, especially when it’s GOTS and OEKO-TEX® certified. It’s hypoallergenic, breathable, and gentle on sensitive skin. Combining comfort, safety, and eco-friendliness, this fabric offers a healthy alternative while protecting the environment.

What’s the difference between conventional cotton and organic cotton?

Organic cotton is grown without pesticides, herbicides, or GMOs, unlike regular cotton, which is often contaminated with chemical residues like glyphosate.

It’s a kind choice for your body and the planet, avoiding the waste of disposable products.

What are the benefits of organic cotton?

Cotton or microfiber: which material is best for period underwear?

Organic cotton is better for intimate health because it’s breathable and prevents irritation, unlike microfiber, which can trap moisture and promote yeast infections. However, microfiber is valued for its discreetness and durability, especially in sports styles.

The perfect balance of comfort and safety.

However, its cost is offset over several years of use, unlike disposable products. As for care, you just need to rinse with cold water before washing, avoiding fabric softener. In return, you get a healthy, eco-friendly, and durable material without compromising on comfort.
