Why PFAS Are a Problem PFAS (per- and polyfluoroalkyl substances) are used for their non-stick, water-repellent, and heat-resistant properties. Highly persistent, they accumulate in the environment (water, soil, biota), and some are known to have harmful effects on human health. In France, ANSES recently published two reports (“National PFAS Monitoring in Water: Overview, Issues, and Prioritization Proposal” and “Proposed National PFAS Monitoring Strategy: Permanent, Explorat

Wastewater treatment is essential for protecting aquatic environments. But it produces a by-product that cannot be ignored: sewage sludge. Each year in France, about one million tons (dry matter equivalent) of sludge are generated. A large share of this volume is recycled on farmland through spreading. This practice is useful, regulated… and under scrutiny. This article looks at three simple questions: Why do we still spread sludge? Where are the real risk zones? What role do

Klearia took part in Cosmetic 360 , held on October 15–16, 2025  at the Carrousel du Louvre in Paris , alongside its partner Pharma & Beauty Group .This major event for the cosmetics and fragrance industry was once again a key meeting point for innovation, this year under the banner of DeepTech and sustainable formulation . Microfluidics Serving the Formulation of Tomorrow On the P&B Group booth, Clément Nanteuil, PhD, Founder and CEO of Klearia , and Mylène Christoph, Innova

A New Step in the Evolution of Microfluidics For over a decade, Klearia has been designing high-precision microfluidic solutions for water monitoring and formulation science. Today, we are entering a new phase: the integration of embedded intelligence into our systems. This approach aims to equip our instruments with real-time analysis and adaptive capabilities, enabling them to automatically adjust their parameters according to operating conditions or process variations. Fro

A Generally Safe Water Supply, but Alarming Signals Are Multiplying Tap water in France remains one of the most tightly controlled consumer products: more than sixty regulated parameters, regular analyses, and constant oversight by regional health agencies. In 2022, over 84% of French citizens consumed compliant water throughout the year. But behind this apparent stability, another reality is emerging: the growing presence of invisible pollutants linked to pesticides, metabol

Modern cosmetics are entering a new era where scientific performance and sensory experience are no longer opposites but deeply intertwined. At the heart of this shift lies nanoemulsion technology. These ultrafine colloidal systems offer enhanced stability, increased efficacy, and unprecedented sensorial qualities while meeting the expectations of clean beauty. Already projected to be adopted by over 60 percent of premium brands by 2025 according to Biofarma Group, nanoemulsio

Safety and transparency at the heart of cosmetic manufacturing Ethanol, also known as ethyl alcohol, is one of the most widely used ingredients in cosmetic products. Found in many perfumes, skincare for oily skin, and sanitizing gels, it is valued for its versatility: it helps dissolve ingredients, provides a lightweight finish, dries quickly, and limits bacterial growth. But despite all its benefits, ethanol also raises questions. At certain concentrations, it can become irr

Safety and transparency are at the heart of modern cosmetic manufacturing. Modern cosmetics are at a turning point. With rapidly evolving regulations and increasing consumer expectations for safe, sustainable, and transparent products, industry players are now required to rethink their entire value chain. France has recently passed a law banning the use of PFAS in cosmetics starting in January 2026, becoming a pioneer in Europe. At the European level, a broader restriction of
