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
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.

Surfactants and Cleansing Products
By: Eric Abrutyn, TPC2 Advisors Ltd., Inc.
Today, cleansing products are available in solid bar, liquid and gel forms and can be based on alkaline salts and synthetic and natural surfactants. When substituted for alkaline salts, synthetic and natural surfactants improve the foam structure and mildness of formulas.
