Silox acquires selected hydrosulfite-related assets from BASF

• Silox improves services to European customers with the strategic acquisition of specific hydrosulfite-related BASF assets
• Agreement reinforces Silox’s long-term commitment to paper and textile industries and secures its position as a premier global supplier

Ludwigshafen, Germany and Engis, Belgium – March 6, 2026

BASF and Silox have entered into a definitive agreement under which Silox acquires selected hydrosulfite-related assets from BASF. The transaction comprises specific assets, including intellectual property rights, special containers, selected production equipment, technical expertise, and related trademarks.

With over 70 years of expertise and plants in Belgium, India and Canada, Silox is a leading producer of sodium hydrosulfite-based reducing and bleaching agents. This acquisition marks a clear strategic move to further strengthen Silox’ role as a trusted partner in the global market.

Hydrosulfites are essential components in different industries, serving as critical reducing agents in the textile dyeing process and as vital bleaching additives in pulp and paper applications.

"By acquiring these assets from BASF, Silox reinforces its long-term commitment to the paper and textile industries and enhances its ability to offer reliable, high-quality hydrosulfites to customers in Europe and around the world," said Jean-Christophe Bogaert, Managing Director – Silox Group.

As announced in September 2025, BASF has decided to discontinue its hydrosulfite production activities in Ludwigshafen as part of its strategic portfolio review. BASF will remain one of the leading suppliers of other inorganic chemicals produced in Ludwigshafen, such as alcoholates, sulfites, and nitrogen salts.
