UK Water Report Could Help Green Formulating

The UK Royal Society of Chemistry has reported that existing waste water treatment systems in the United Kingdom are not designed to remove chemicals in personal care products and that those chemicals are seeping into the water system.

Cream in Powder Form: An New Concept in Makeup

The present work describes a cosmetic technology based on a newer formulating concept—cream in powder form. The final formulation can be created by two different technical processes to produce either water- or oil-based cosmetics. In each case, the proper selection of ingredients determines the stability of the finished products.

Cloud point vs. High cloud point

Industry expert Tony O’Lenick examines the difference between cloud point and high cloud point.

Free vs. Controlled Radical Polymerization

Tony O’Lenick asks: What is the difference between free radical polymerization and controlled radical polymerization?

Water Activity

Water activity is a key consideration in preserving cosmetics. As this article discusses, there is an important difference between the amount of water present in a product and availability of this water for microorganism growth.

Residual Monomer in Radical vs. Condensation Polymerization Techniques

Industry expert Tony O’Lenick explains the difference between residual monomer concentration in radical vs. condensation polymerization techniques.

Bench and Beyond: Correlating Water Contact Angles and Moisturization/Sensory Claims

While staff that normally writes the Bench & Beyond column is taking some time off, this space offers an article by Olga V. Dueva-Koganov, B. Scott Jaynes, Colleen Rocafort, Shaun Barker and Jianwen Mao at Ciba Specialty Chemicals Corporation in Tarrytown, N.Y., USA.

Preparing PIC Emulsions with Very Fine Particle Size

A new technology has been developed for the production of o/w phase inversion concentration (PIC) emulsions with a very fine particle size and excellent storage stability. The concept is based on non-ethoxylated emulsifiers and can be easily used for the preparation of impregnating lotions for cosmetic wet wipes.

Comparatively Speaking: Emulsion vs. Invert Emulsion

Industry expert Tony O'Lenick explains the difference between an emulsion and an invert emulsion.

Formulating Water-in-Oil Emulsions: A Scary Endeavor

Formulating water-in-oil emulsions is inherently more difficult than oil-in-water emulsions.

Amino Acid Produced Through Fermentation

Kyowa Hakko has announced its creation of a fermentation-based method for the commercial production of L-Tyrosine.

Chanel Incorporates New Process

Chanel will be introducing a recent scientific process in its fall launch of Sublimage Essential Regenerating Cream.
