James Robinson Speciality Ingredients (headquarters: Huddersfield; CEO:Sanketh Varalwar) and Mitsui Fine Chemicals, Inc (Tokyo; President & CEO: TANAKA Hisayoshi) are pleased to announce a new chapter in the relationship between the two companies. Building on their successful history of collaboration, and the agreed strategic partnership, Mitsui Fine Chemicals will now represent the Jarocol® hair dye range as the exclusive distributor for the Japanese market.

 

Through this partnership, formulators now have access to a vibrant spectrum of globally renowned Jarocol® dyes. These tools allow for everything from the precise grey coverage essential to Japanese consumers to the vibrant fashion shades that drive current trends. By combining JRSI’s technical heritage with Mitsui’s deep local expertise and established relationships with customers, the collaboration provides the necessary support for brands to create the next generation of hair colours for Japan.

 

“The foundation of our relationship with Mitsui Fine Chemicals is rooted in a shared curiosity for science,” said Sanketh Varalwar, CEO of James Robinson Speciality Ingredients. “Having worked together for many years on our Reversacol™ photochromic dyes, bringing the Jarocol® range into the fold feels like a natural evolution. The Mitsui Fine Chemicals team already understands our portfolio and our commitment to quality inside and out. We are looking forward to seeing this partnership support Japanese brands as they bring their consumers’ aspirations to reality.”

 

Mr. Hisayoshi Tanaka, Representative Director, President and CEO of Mitsui Fine Chemicals Comments; I am very pleased that we have agreed on a strategic partnership with James Robinson Specialty Ingredients of the United Kingdom for Japan. By combining our respective strengths—JRSI’s dye expertise and our insight into the market—I am confident that we will be able to provide customers with hair color dyes of even higher quality and safety. This partnership represents an important initiative that will strongly support the expansion of our hair care business, and we will continue to pursue value creation that meets the expectations of the market.
