Surface Active Agents

Dr. Guido Bognolo has a degree in theoretical chemistry and has spent his professional career working on the technology, applications, marketing, strategy, and business acquisition of surface active agents in multinational chemical companies.He was for many years the managing director of WSA Associates, a company providing consulting services for technology and strategic investments to several companies operating in the field of surface active agents and specialty chemicals. As general secretary of the Confederation of Senior Expert Services (CESES) he executed many consulting missions in the People's Republic of China. He holds a master's degree in business administration from the Solvay Business School of Economics and Management in Brussels. He is the author of several publications on the technology, marketing, and strategy aspects of surface active agents, as well as chapters in reference books.
