The consumers’ increasing demand for natural cosmetics has become one of the industry’s most important drivers. As raw material supplier we want to support our customers in offering these kind of products.

As each country had its own standard and its own definition of natural and organic ingredients. We choose to apply for a COSMOS approved certificate for our raw material. COSMOS harmonised all these standards and created an international standard for organic and natural cosmetics.
