Role of Photography in Acne Metrics*

To optimally treat acne, an accurate severity assessment is required1 and while visual assessments have relied on text descriptions, lesion counting and photographic methods, an ideal grading system would be more accurate and reproducible. Further, its ease of use, and time and monetary costs are also important. Here, the authors consider different approaches for improved acne assessments using photography.

Visualizing the Impact of Emulsifiers on Emulsion Perception

This paper describes an approach to systematically investigate the intrinsic effects of emulsifiers, quantify them and translate them into consumer preferences. These are processed mathematically and displayed in a simplified, two-dimensional map to assist formulation work.

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.

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.

Multiple Emulsions: Applications in Cosmetics

Multiple emulsions and factors affecting their preparation are discussed in this article that also lists the advantages of each of the two main types—w/o/w and o/w/o—and gives examples of each in cosmetic formulations.

Plant Cell Technology

While plant stem cells initially were marketed for their technological potential, they recently have been identified as an alternative, sustainable mean to produce nature-derived extracts and molecules.

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.
