Comparatively Speaking: Soluble vs. Insoluble

What’s the difference between something that is soluble vs. insoluble? Tony O’Lenick explores this notion. At first, he writes, this may seem quite simple but a deeper investigation provides formulation insight.

PQ-10: How the Industry Utilizes This Cationic Polymer

Polyquaternium-10 is utilized by formulators in rinse-off and conditioning hair, cosmetic and body products. This article addresses the ingredient's production, properties and applications in the personal care industry.

[podcast] How Caffeine Jump-starts Skin Hydration

The Estée Lauder Companies is getting a real charge out of its latest research findings: caffeine affects skin’s electric potential and enhances hydration. Learn more from our podcast with Jaime Emmetsberger, Ph.D., of Tom Ford Research.

Restoring Hair and Scalp Health: Ceramide-2 Analog for Conditioning and Barrier Benefits

Since ceramides are essential for protecting skin and hair, the natural conclusion would be to use them as cosmetic ingredients. However, naturally occurring ceramides are difficult to extract and can carry a high cost. A structural analog to naturally occurring ceramide-2 was therefore developed.

Plant-Based Hydrogels: Applications in Cosmetics

Hydrogels provide high water content, elasticity, softness and biocompatibility to cosmetics and skin care products. This article reviews the main categories of polysaccharides that form hydrogels for use in the cosmetic industry.

Comparatively Speaking: Homologous vs. Analogous Polymers

What can we learn from the structure/function differences within a chemical family? In this installment of "Comparatively Speaking," Anthony J. O'Lenick, Jr., illustrates with a closer look at homologous vs. analogous polymers.

A New Code for Skin Care: RNAi to Rewrite Cosmetics, Part I

For several years, the cosmetics industry has been exploring the potential for RNA interference (RNAi) technologies in skin and hair care. This first in a three-part series reviews the utility of RNAi and current efforts to bring RNAi-based cosmetics to market. Part II, in January 2018, will consider the delivery of RNAi into skin.

In Light of Exposure: Understanding Avobenzone Part I, Characterization

Avobenzone is a widely used UV-absorbing organic filter. Its dynamic nature and photophysical and photochemical properties are responsible for its widespread use. This first in a two-part series reviews its inherent characteristics and behavior in solvents; part two will consider its behavior with other sunscreens and in formulas.

Preserving the Facts on Parabens: An Overview of These Important Tools of the Trade

Parabens have a long history as effective preservatives in foods, cosmetics and drugs, with extensively documented human and environmental safety profiles. This article reviews these important ingredients.

The Name's Bond, H-F Bond. Leveraging Divergent Fluorine Forces

Intermolecular forces such as dispersion forces and hydrogen bonds are the basis for a theory explaining the behavior and benefits of perfluoropolyethers and perfluorocarbons. The former, in liquid form, are explored here for their application in cosmetics and personal care; the latter are described for speculation purposes.

Olefin Synthesis Simplified

Decarboxylative alkenylation is a new chemical reaction that is said to "easily turn carboxylic acids into alkenes (or olefins)." Researchers believe this will lead to the discovery and development of a variety of new drugs and other chemicals.

The Brave New World of Silicone Alternatives

The road forward for cosmetic formulation doesn't include as many of the silicones of old, according to Tony O'Lenick, president of Siltech LLC.
