HLB: A Valuable Invention

Mr. Gallagher noted that when nonionic surfactants were first developed, many formulators didn’t know how to work with them. To facilitate their use, Mr. Griffin developed the HLB system to provide guidance on selecting the right emulsifier and surfactant.

“Bill Griffin and his Atlas colleagues made an important contribution to the history of American chemistry,” noted Mr. Gallagher. “He invented this system to make these new nonionics emulsions and surfactants understandable to the chemists who would use them in so many different products.”

The William C. Griffin Innovation Center houses Croda’s industrial research and development laboratories. It will support innovation in the industrial markets of crop care, lubricants, oilfield, coatings and polymer additives.

The Atlas Point Commercial Center includes Croda’s Skin Innovation Laboratory, which will support skin care product concepts for the personal care industry, as well as office space for Croda’s industrial sales team.

The completion of the renovations to these two buildings brings Croda’s investment in the manufacturing site to $20 million since it acquired Uniqema from ICI in 2006. The company intends to make more capital expenditures during the next 10 years to allow the site to become a world class manufacturing facility, according to Croda.
