A Brief Review of Polymer/Surfactant Interaction

In this article, the significance of parameters such as correlation length (blob size), micelle structure, comicellization, polymer adsorption conformation and coacervate structure are introduced with relevance to the conceptual appreciation of polymer-surfactant interactions and its bearing on recent advances in conditioning shampoos.

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.

Patent Picks—Antimicrobials, Cleansers, Fragrance/Malodor and Delivery

This edition of "Patent Picks" features recently issued patents relevant to cosmetic product development, from antimicrobial compositions and ceramide emulsions, to foaming alcohol, fragrances and cysteine to counteract malodor, among others.

Patent Picks—Cosmetic Cornucopia: Antioxidants, Formulating Aids, Firethorn Skin Lightening and More

This special edition of "Patent Picks" features a cornucopia of recently issued patents relevant to cosmetic product development; from water-dispersible cellulose thickeners and polyunsaturated fatty acid (PUFA) polyketide synthase systems, to odorant receptor modulators.

Comparatively Speaking: Simple Salt vs. Ionic Liquid

Unlike common salts, ionic liquids are salts in which the ions are poorly coordinated, resulting in molecules that are liquid below 100°C. The use of ionic liquids will aid the formulator in improving delivery efficiency.

Patent Picks—Hair and Eyelash Growth, Fixatives, Surfactants and More

Chosen biweekly by Rachel Grabenhofer, Cosmetics & Toiletries magazine editor, for their relevance to personal care, Patent Picks are taken from publicly available sources. This edition features recently issued patents relevant to hair care, styling and growth.

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.

Structured Surfactant Systems for High Performance Shampoos

Specialized surfactant systems that form multilamellar vesicles can be used to design high performance shampoos that outperform micellar formulas. These materials combine with and stabilize actives ranging from molecular to particulate, liquid to solid, and hydrophobic or cationic, to deliver them equally to damaged and virgin regions of hair to act where they are needed most.

Comparatively Speaking: Silicone Anionics and Cationics vs. Soft Complex for Hair Care

The presence of ionic groups affects silicone in an analogous way to how ionic groups affect fatty surfactants. Here, Tony O'Lenick explains how molecular modifications to silicones can result in ionic complexes that are soluble in water and compatible with each other.

Comparatively Speaking: Lowering Surface Tension in Water vs. Oil

Industry expert Tony O'Lenick discusses the differences between lowering surface tension in water vs. oil phases, noting that formulators should consider surface tension and its role when choosing ingredients for either phase.

Comparatively Speaking: Fatty Alcohols vs. Fatty Acids vs. Esters

In the present discussion of fatty alcohols, fatty acids and esters, Tony O’Lenick recruits Ismail Walele of Phoenix Chemical to explain the differences between them.

Polymers in Personal Care

Polymer use began in the 1800s with cellulose derivatives, the vulcanization of rubber, and styrene synthesis; but in reality, it started more than four million years ago with the formation of DNA and proteins. Polymers are a diverse class of chemistry. By definition, they are large molecules made up of chains or rings of linked monomer units—simple reactive building blocks. Smaller molecules or monomers are combined to form polymers that possess a characteristic chain structure of multiple repeating units that can be related or different.

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.

Product Benchmarking: Lip Service, Window Dressing or Competitive Advantage?

In a fast-moving marketplace, few would disagree that product performance benchmarking is critical to achieving an industry-leading position. However, is this statement just lip service in the current environment?

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.

Formulating Conditioning Shampoos

Conditioning shampoos came into being when in order to replace hair body that had been lost by frequent shampooing and conditioning, formulators sought to introduce ingredients that would be deposited on the hair during the shampooing process. This article addresses the basics and the most recent developments in formulating conditioning shampoos.

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.
