One Rock Capital Partners LLC has successfully completed the acquisition of the manufacturing site in Kankakee, Illinois, and the associated businesses of vegetable-oil-based raw material sterols and natural vitamin E, anionic surfactants and esters produced there, from BASF.

Tony W. Lee, Managing Partner of One Rock, said, “In working closely with our Operating Partners and BASF, we have been impressed by the talented team in Kankakee and are eager to build on the company’s well-deserved reputation for high-purity manufacturing and customer service under the Kensing brand.”

R. Scott Spielvogel, managing partner of One Rock, added, “Kensing will maintain the longstanding commitment to quality and reliability for which the organization at Kankakee is well-known, and we look forward to bringing renewed focus and resources to the company to drive continued growth across the core end markets it serves.”

In conjunction with the completion of the transaction, Serge Rogasik has been appointed chief executive officer of Kensing. He most recently served as senior executive vice president of personal care at Vantage Specialty Chemicals.

Rogasik said, “I am very excited to lead Kensing at this momentous time. Demand for plant-derived ingredients is growing at a fast pace in our global markets and Kensing provides a very strong platform from which to expand our portfolio and services to our customers.”
