The useful question is what changes for users, developers or buyers, and whether the announcement stays industry context or becomes something people can actually use.

Solvay and Pantys, a sustainable femtech brand, have renewed their partnership for three years to advance menstrual health and inclusion. The collaboration builds on a 2017 agreement, combining Solvay’s Amni Soul Eco® technology with Pantys’ reusable, clinically tested underwear designed for people with menstrual or incontinence needs. The partnership aims to improve daily life while reducing environmental impact, with a focus on health and inclusion aligned with UN Sustainable Development Goals.

Under the new agreement, Pantys will scale programs for vulnerable communities through product donations and education, funded by Solvay. A key innovation is the generation of social credits, independently verified units that reflect tangible improvements such as school attendance during menstruation or increased time for work and study. The W+ Standard, developed by WOCAN and verified by third parties, will measure impact, with credits recorded on the S&P Global registry for transparency.

Solvay’s financial support will enable Pantys to launch the social credits program, targeting 7,000 people and generating 40,000 credits by 2026. The initiative aims to expand to 70,000 people and 450,000 credits by 2028. The partnership emphasizes rigorous, transparent measurement of social impact, inviting broader corporate participation in certified, scalable solutions.

Pantys, a certified B Corp, is a pioneer in sustainable femtech, offering clinically approved absorbent underwear that avoids up to 16,000 disposable products per customer. Solvay, a global chemical company with €4.3 billion in net sales in 2025, contributes sustainable chemistry to the collaboration, reinforcing its commitment to carbon neutrality by 2050.
