The chemical business: a glimpse into the history and future of Angus

Previously a subsidiary of Dow, Angus Chemical Company was acquired in early 2015 by Golden Gate Capital. Today, Golden Gate owns 50% of Angus, having sold 50% to the Ardian investment fund in October 2020.

Angus has been in business since 1936. And like so many ingredient suppliers and specialty chemical companies, Angus serves many consumer and industrial markets, such as beauty and personal care, home and industrial cleaning, paints and coatings, electronic chemicals, chemical manufacturing, water treatment, oil and gas, and leather tanning.

Based in Buffalo Grove, Ill., Angus Chemical Company continues to innovate to meet current and future market needs, as exemplified by the launch of the DL-2AP ULTRA PC. To keep the innovation pipeline full, Angus recruited Dr. Kathleen Havelka as Vice President of Research and Development last April.

“Kathleen has an impressive track record of innovating, leading the introduction of new technologies, fostering collaboration and finding improved technical solutions to support growth.” David Neuberger, Chairman and CEO of Angus, noted in a press release released this month.

“She brings a deep understanding of the strategic end markets we serve, as well as the diverse needs of our customers around the world,” he said, adding, “I look forward to adding Kathleen’s scientific experience and expertise to the Angus leadership team. “

And earlier this year, Angus was awarded the Gold level of recognition for its sustainability performance by EcoVadis, another indication that the beauty ingredients company intends to keep pace with the expectations of the industry.
