New : Verification of natural Cosmetic Ingredients according to ISO 16128 – An Innovative Service Offered by Ecocert

Understanding the ISO 16128 standard on natural content

ISO 16128 is an international standard that provides guidelines and a methodology for determining the natural origin of cosmetic ingredients and formulations. It allows the calculation of natural indexes based on defined criteria and is divided into two parts: the first defines the categories of ingredients, while the second outlines a method for calculating the natural indexes.

Independent verification in the service of transparency

While many companies calculate the natural index of their ingredients themselves, the absence of external verification can undermine the reliability of the data provided. In this context, Ecocert offers an independent verification service based on a rigorous analysis of technical documentation by experts recognized for their knowledge of the standards COSMOS, NATRUE, and other industry standards. This process results in the issuance of an official verification report, which serves as a strategic tool for raw material manufacturers, allowing them to clearly, reliably, and verifiably demonstrate the natural origin of their ingredients.

A tool to support differentiation strategies

The verification service offered by Ecocert provides valuable assurance to brands engaged in certification, eco-design, or regulatory compliance initiatives. By relying on a recognized method and independent assessment, cosmetic ingredient manufacturers gain a competitive edge, enabling them to highlight the quality and naturalness of their raw materials to their clients.

Testimonial from Sara Mayor, Home & Personal Care Department - Ecocert, on this service

“In a sector where the demand for natural products continues to grow, it has become essential to ensure that naturalness claims are based on solid and verifiable foundations. Our approach aims to provide independent verification of the natural indexes of cosmetic ingredients, based on the ISO 16128 standard. This process is built on a transparent methodology, ensuring the integrity of the results, without implying any labeling or certification for the products themselves. For brands and manufacturers who wish to go further and adopt a more comprehensive approach - including the origin of raw materials, production methods, environmental respect, traceability, and ethics - certification remains essential. That is what we offer with labels such as COSMOS or NATRUE.”

Securing naturalness claims With the implementation of new European directives - particularly Directive 2024/825 “Empowering Consumers for the Green Transition” and the “Green Claims” directive - brands will now be required to substantiate their environmental claims with objective and verifiable data.

In this context, Ecocert’s ISO 16128 verification provides a concrete solution, enabling raw material suppliers to secure their naturalness claims and contribute to a stronger culture of transparency. It allows them to position themselves as reliable and responsible partners for all stakeholders.
