Comparatively Speaking: Wetting vs. Superwetting

In this edition of "Comparatively Speaking," industry expert Tony O'Lenick discusses the terms wetting and superwetting in relation to the ability of a surfactant to wet a substrate.

Comparatively Speaking: Trisiloxane vs. Dimethicone Copolyol

In this edition of "Comparatively Speaking," industry expert Tony O'Lenick explains the difference in stability between dimethicone copolyols and trisiloxane, a class of dimethicone copolyols.

Comparatively Speaking: Amphiphilic vs. Ionic Amphiphilic Molecule

Tony O'Lenick explains the difference between amphiphilic and ionic amphiphilic molecules, the interactions of which may help formulators to maximize the effectiveness of formulations.

Surfactant Concentrate for Mild, High-foam Cleansers

Colonial Chemical Inc. has introduced a biodegradable baby shampoo concentrate to its line of eco-friendly, mild products.

Coconut-derived Surfactant for Natural Formulations

Colonial Chemical Inc. has added a surfactant derived from coconut to its line of nature-based personal care products.

Vegetable-based Surfactant for Natural Hair Conditioning

Rhodia will introduce its vegetable-based surfactant for hair care at NYSCC Suppliers' Day 2010.

Comparatively Speaking: Natural- vs. Oxo- vs. Ziegler-derived Alcohols

Tony O'Lenick explores the difference between fatty alcohols derived naturally and those derived through the oxo process and the Ziegler process.

Mild Surfactant for Dense Foam

This mild surfactant from Innospec can be used as a primary or secondary surfactant and is designed to produce a dense, luxurious foam and an elegant after feel.

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.

Comparatively Speaking: Amphoteric vs. Ampholyte

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: 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: Aqueous Surfactant vs. Silicone Surfactant

Industry expert Anthony O'Lenick Jr. explains the difference between molecules that act like surfactants for aqueous systems versus oil systems.
