Patent Picks— Foam Enhancement, Functionalized Polymers, Modified Sorbitan Siloxanes, Bacterial Cellulose Network and More for Cleansing

Chosen biweekly for their relevance to personal care, Patent Picks are taken from publicly available sources. This edition features technologies related to cleansing skin and hair.

Comparatively Speaking: Solubility in Surfactants vs. Compounds

Anthony J. O'Lenick provides a brief overview of solubility as the key to surfactant activity and compares it with compounds such as sodium chloride, for the benefit of novice formulators.

Comparatively Speaking: Amphilic vs. Non-amphilic Compounds

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.

Indonesia Expects Professional Hair Care Boom

Although the Indonesian hair care market is still modest in size, being less than 5% of the U.S. market, it has enjoyed a growth of almost 10% since 2007.

Comparatively Speaking: Complexation vs. Coacervation in 2-in-1 Shampoos

Hair care traditionally involves cleansing with anionic or amphoteric surfactants, rinsing, then using a conditioner with cationic surfactant and cetyl and stearyl alcohol. Combining these as 2-in-1 products is not easy but complexation and coacervation approaches can achieve such.

Compass—'Trying' Time

From cover to cover, this issue is packed with approaches to create and measure experiences in personal care, which nicely matches this year’s new “give it a try” sentiment—after all experiment leads to experience.

Anionic/Cationic Complexes

Understanding the interactions of surfactants is important to optimizing their properties in formulations. The author describes how the anionic/cationic interaction is critical to properties such as foam, viscosity, conditioning properties and minimal irritation.

Compass—Connecting the Dots

Whether your bubbles foam or lather, your hair takes a wild turn, or your wellness weighs on the health of microbes, Cosmetics & Toiletries aims to connect the dots.

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.

Compass: When Worlds Colide

This issue of Cosmetics & Toiletries magazine looks at the inner and outer worlds of beauty and even delves into the future with a look at what the newest ingredients formulators will use to build formulas of tomorrow.

Compass—Bring on the Bubbly!

Bubbles are an integral part of this issue of Cosmetics & Toiletries magazine—in the form of cleansing products and the ingredients employed therein.

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.

WaterOilImmiscible850

Comparatively Speaking: HLB vs. SLB

Efficiently formulating products using alkyl dimethicone polymers requires knowing their composition, solubility in the oil phase chosen, and a metric to understand which values are necessary for that particular oil phase. SLB is a starting point for such determinations.

Comparatively Speaking: Hydrotrope vs. Emulsifier

Both emulsifiers and hydrotropes are used in personal care formulas. They show several similarities but serve different functions. In this installment of our "Comparatively Speaking" series, Tony O'Lenick explains.

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: PPG vs. PEG

The chemistry of PEG, PPG or combinations thereof have an impact on the functional properties of formulas. Knowledge of these materials will help the chemist understand both the effects of reacting these materials on fatty alcohols as well as the performance of emulsifiers and wetting agents.

Comparatively Speaking: CMC vs. RF50

Industry expert Tony O'Lenick refers to his son and polymer scientist at the University of Tennessee, Thomas O'Lenick, to explain the difference between critical micelle concentration and reduction factor 50% (RF50) with regard to measuring silicone surfactant effectiveness.

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.
