Comparatively Speaking: CAPB from Coconut Oil vs. Fatty Acid

By: Anthony J. O'Lenick, Jr., Siltech LLC

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.

Comparatively Speaking: Amphoteric vs. Ampholyte

By: Anthony J. O'Lenick, Jr., Siltech LLC

Here, O'Lenick explains the terms amphoteric, which is used to describe compounds having two or more different groups with various charges, and ampholytes, which have a fully quaternized nitrogen and consequently cannot lose their positive charge.

Comparatively Speaking--Analytical Methods: The mg KOH/gm System

By: Anthony O'Lenick, Jr., Siltech LLC

This is the first of several columns that will examine key analytical methods used in quality control to discuss their application to raw materials. The mg KOH/gm system is the most commonly used system to analyze surfactants and it originally was developed by chemists in the soap business.

Comparatively Speaking: Static vs. Dynamic Measurement of Surface Tension

By: Anthony J. O'Lenick, Jr., Siltech LLC

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: Surface Tension in Water vs. in Formulation

Water surface
By: Anthony J. O'Lenick, Jr., Siltech LLC

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.
