Unilever, University of Liverpool Partner to Research Next Generation of Renewable Chemicals

The three-year project will involve developing renewable chemicals from the surplus sugars, fats, oils and carbohydrates produced via commodity byproducts and forestry wastes.

Partnering to Make Metathesis a Commercial Reality

In materials science, metathesis has a unique ability: it fills gaps. 9-Decenoic methyl ester is one of the specialty materials produced by Elevance via olefin metathesis, an organic reaction that can break natural oils into pieces and recombine them without undesired by-products and hazardous wastes.

Cold Processing of Emulsions

The use and application of emulsions and emulsion science are widespread through the personal care industry. Conventional methods for processing emulsions require significant quantities of energy and time, thus cold process emulsion technologies have gained popularity. These provide the means to reduce both the energy demand and timescale of manufacturing processes, as will be described here.

Silverson Solves Conversion Problems in the Lab

Having problems with conversions during product development in the lab? There's now an app for that. Silverson Machines Inc. has launched Silverson Conversion Tools, an app available in Apple’s App Store that contains a versatile set of conversion and calculation tools suitable for use in almost any process environment.

Greening Personal Care Chemistry

Multiple economic, legislative and customer pressures are forcing an unprecedented level of change in chemical manufacturing and the design of chemical products. The authors examine the drivers for change and opportunities across the product lifecycle for green and sustainable chemistry including the use of renewable resources, cleaner synthesis methods and greener products.

The Harvest of Marine-derived Cosmetic Ingredients: A Case Study of Pseudopterogorgia elisabethae

This paper reviews the knowledge and nature of the harvest practices for the octocoral Pseudopterogorgia elisabethae. P. elisabethae extract has been used for nearly two decades in cosmetics and preparations for skin benefits, and a review of the harvest provides product developers with an interesting case study of the harvest of a marine resource.

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.

Troubleshooting Lab Bench to Production

Led by column editor Peter Tsolis of The Estée Lauder Companies, this recently added column in the Cosmetics & Toiletries magazine lineup covers some of the more common formulation challenges and suggests solutions for novice formulators as well as seasoned experts.

A Green, Solvent-free Biocatalytic Method to Produce Cosmetic Esters

Cosmetic esters can be produced effectively via a solvent-free, biocatalytic method. This green process, described by the authors, involves combining two reactants and an enzyme, and is driven to high conversion by the removal of by-products through a nitrogen purge—in turn producing high purity materials directly from the reactor.
