BASF, a global leader in additives for the coatings industry, has successfully transitioned to using bio-based ethyl acrylate (EA) in the production of its Rheovis range at its manufacturing sites in Ludwigshafen, Germany, and Bradford, United Kingdom. This shift marks a significant step toward reducing the environmental footprint of its products while maintaining their high-performance standards.

The updated Rheovis line now contains a biogenic carbon content of up to 35%, as certified by ASTM D6866-18 using 14C-traceable analysis. In comparison to fossil-based versions, the bio-based alternatives exhibit up to 30% lower product carbon footprints (PCF), supporting sustainability targets throughout the coatings value chain.

“The switch to bio-based feedstock underlines BASF Additives’ commitment to enabling formulators in their green transition while ensuring continued supply reliability and efficiency,” said Sylvain Pascal Huguenard, vice president of global business management for additives at BASF. “Through BASF’s optimized production processes and our integrated Verbund approach, we can further reduce our PCF and strengthen sustainability across the board.”

The chemical composition and technical performance of the Rheovis® products remain unchanged, ensuring that customers receive the same quality and reliability while benefiting from improved sustainability.

Joachim Burger, head of sales for Additives EMEA at BASF, emphasized the company’s broader vision: “With sustainability at the core of our innovation, the upgraded Rheovis® range will empower our customers to develop more eco-friendly formulations. We’re proud to support formulators on this journey and remain committed to shaping the future together.”

In addition to reformulating existing products, BASF has expanded its Rheovis® portfolio with the launch of two new HASE (Hydrophobically Modified Alkali Swellable Emulsion) rheology modifiers—Rheovis® HS 1101 and Rheovis® HS 1153. Both are free of added biocides and have been specifically designed with higher biogenic content to enhance both performance and sustainability.

BASF also offers the option to apply its Biomass Balance (BMB) approach, which allows further PCF reductions by attributing bio-based feedstocks to products within its certified production system. This flexibility helps customers improve the renewable share in their formulations and reduce dependency on fossil-based materials.

With its evolving portfolio of bio-based solutions, BASF continues to lead in supporting a circular economy and offering customers viable pathways to meet growing regulatory and environmental demands.

BASF is committed to creating chemistry that supports a sustainable future. The company aims to become the preferred chemical partner for customers driving the green transformation. BASF integrates economic success with environmental stewardship and social responsibility. Its core business segments include Chemicals, Materials, Industrial Solutions, and Nutrition & Care, while its independent business units are grouped under Surface Technologies and Agricultural Solutions.
