Critical Micelle Concentration: Measuring Surfactant Efficiency

Critical Micelle Concentration (CMC) values are important indicators when considering which surfactant will provide optimal performance benefits for your formulation. But what is CMC and why is it important for formulators? When a certain amount of surfactant is added to water, the molecules will begin to form micelles. Micelles consist of agglomerates of surfactant molecules …

Material Update: Dimethyl Sulfoxide (DMSO)

DMSO is used as a polar aprotic solvent in several applications, including electronics (photoresist stripping and cleaning), polyurethane coating formulations, fiber manufacturing and as a general purpose clean-up solvent. Due to lower toxicity concerns and minimal regulatory constraints, DMSO has been found to be an effective alternative to other polar solvents such as dimethyl acetamide …

The need for Nonyphenol Ethoxylate (NPE) alternatives (EPA phase out actions on the horizon)

It’s no secret that the EPA has targeted nonylphenols and nonylphenol ethoxylates (NPEs), both falling into the general surfactant groups of alkylphenols and alkylphenol ethoxylates (APEs), for phase out in the coming year. In the EPA NP and NPE Action Plan, published in August of 2010, NPEs were described as highly toxic to aquatic organisms, …
