Technical insights and industry updates
March 2025
Regulatory pressure on per- and polyfluoroalkyl substances (PFAS) is accelerating across North America and Europe. We outline the key deadlines, the most affected product categories, and the technical options available for formulators seeking compliant alternatives without sacrificing performance.
November 2024
A water treatment client engaged us to investigate chronic batch failures. Control charts revealed a pattern that pointed not to the process itself, but to a raw material supplier's own process change — one they had not disclosed. This case study walks through how statistical process control uncovered the root cause in under two weeks.
August 2024
Full factorial experiments are rarely practical in a production environment. We discuss how fractional factorial and response surface designs allow manufacturers to map the relationship between key process variables and product quality with a fraction of the runs — and how to interpret the results correctly.
April 2024
A key raw material going end-of-life is one of the most disruptive events a formulator can face. We share a structured framework for evaluating replacement candidates, qualifying substitutes, and managing the transition without production interruption.
January 2024
Specifications that are tighter than process capability guarantee chronic non-conformances. We explain how process capability indices (Cp, Cpk) should inform specification setting, and why working backwards from customer requirements without understanding your own process is a recipe for ongoing quality problems.
