Nequia Group BV is an oral‑care formulation consultancy specializing in the development, optimization, and troubleshooting of toothpaste, mouthwash, gels, whitening systems, and enamel‑strengthening technologies for EU and US markets. We combine scientific rigor with hands‑on formulation experience to help brands create safe, effective, and commercially successful products.
Our work bridges chemistry, regulatory compliance, and real‑world manufacturing, ensuring every formula performs not only in the lab — but also on the production line.
With more than 15 years of formulation experience, Nequia supports companies across the full development cycle:
Whether you’re refining an existing formula or building a new oral‑care line from scratch, we help you move from concept to production with confidence.
Nequia operates with access to laboratory facilities at the Bio Science Park in Leiden, enabling controlled testing, iterative formulation work, small‑scale prototyping, stability evaluation, and ingredient compatibility studies.
This allows us to combine scientific precision with practical, real‑world formulation development.
We follow a structured, methodical process designed to reduce risk and accelerate development:
Understanding your goals, constraints, claims, and regulatory requirements.
Developing or optimizing formulas based on performance, stability, sensory profile, and manufacturing feasibility.
Evaluating stability, compatibility, whitening performance, and active delivery.
Iterating based on data, feedback, and manufacturing requirements.
Ensuring a smooth transition from lab to pilot to full production.
Every project is handled with precision, transparency, and scientific integrity.
