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.

Comparatively Speaking: Amphilic vs. Non-amphilic Compounds
By: Anthony J. O'Lenick, Jr., Siltech LLC
The term amphilic refers to a compound that possesses at least two groups that, if present in pure form, are insoluble in one another. The groups that are most commonly encountered are oil and water.
