Comparatively Speaking: Surface Tension in Water vs. in Formulation
Many published studies of surfactants use pure surfactant in distilled water. However, a formulation is almost never a single surfactant in water. Here, industry expert Tony O'Lenick compares the surface tension of a surfactant added in water with that in a formulation.

Comparatively Speaking: Static vs. Dynamic Measurement of Surface Tension
Surface tension determines the properties of formulations. How does one measure surface tension? Since, realistically, there is more than one surface tension in a liquid, measurements can vary depending upon the method used. Here, industry expert Tony O'Lenick discusses static and dynamic approaches to measuring surface tension.

Comparatively Speaking: The INCI Names vs. Properties of Silicone Surfactants
Surface tension is a ruling factor in the formulator's world. In this edition of "Comparatively Speaking," Tony O'Lenick explains its influence on foam and wetting; he also demonstrates how little the INCI name reveals about a material's properties.
Cleansing
Comparatively Speaking: CAPB from Coconut Oil vs. Fatty Acid
Anthony J. O'Lenick, Jr., explains that CAPB can be made from two different processes, one with coconut oil and the other with fatty acid, which create two potential differences that affect how the material works in a formulation.
