Clariant has received US Food and Drug Administration (FDA), approval for its bio-based Licocare RBW wax additives for use in rigid polyvinyl chloride (PVC) food-contact applications. The authorisation, effective May 7, 2026, extends the company's existing FDA approval beyond polyester materials to include rigid PVC.
The approval covers the complete Licocare RBW product range, including the RBW 100 series, RBW 300 series, and the grades Licocare RBW 360 Vita and RBW 560 Vita. The additives are authorised for use as processing aids, lubricants, release agents, and slip additives in single- and repeat-use rigid PVC applications across all food types, except for infant formula and human milk contact.
For direct food-contact applications, the additives are approved at levels up to 0.5% by weight under conditions of use C through H, with a temperature maximum of 80°C for hot-fill applications. It has also received an Opinion Letter of No Objection (LONO) for repeated use up to 1% concentration in food-contact articles for food processing equipment made of rigid PVC.
The dual authorisation enables use across multiple applications, including rigid PVC containers, packaging materials, and food processing equipment components such as conveyor belts, cutting boards, storage containers, seals, and gaskets. The different concentration levels allow formulators to adjust specifications based on their specific application requirements while maintaining regulatory compliance.
The FDA approval adds to its existing regulatory authorisations for the Licocare RBW portfolio. In February 2026, the EU Commission published authorisation based on EFSA's positive opinion for the same product line in PET, PLA, and rigid PVC materials. The company also holds authorisation from the Japanese food safety authority. This combination of approvals provides manufacturers with regulatory compliance across major international markets.
Diederik Goyvaerts, market manager, additives at Clariant, said, "Achieving FDA approval for our Licocare RBW additives in rigid PVC applications demonstrates Clariant's commitment to delivering sustainable solutions that meet the highest regulatory standards across multiple jurisdictions. This authorisation represents years of dedicated work and opens significant opportunities for manufacturers to transition to renewable alternatives while maintaining full compliance with food safety regulations in both North American and European markets."
