In the mechanical testing world, the tendency for materials to fail under a repeated stimulus is termed fatigue testing, and this article discusses this topic in relation to hair breakage. It will be shown that this alternative testing approach provides considerable insight into the cause of hair breakage, and subsequently allows for the identification of strategies for its minimization; it will also be demonstrated how learning this provides the underlying theory by which anti-breakage and even “strengthening” claims are crafted.
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.
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.
At recent European and Asia-Pacific events, a number of speakers suggested that consumer behavior was becoming a major barrier to sustainable development in the beauty industry.
The IFSCC conference covered an array of subjects—from the psychology of rotating brushes, and discussion of neuron-adipocyte crosstalk to limit emotional stress-mediated fat accumulation; to hair straightening and conditioning, various visualization tools, and novel formulation approaches.
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.
Patent Picks are taken from publicly available sources and cover recent patents issued, or applied for, in the cosmetic and personal care industries and relevant peripheral markets. This edition features methods and processes for analyzing and producing cosmetic products and materials.
The three-year project will involve developing renewable chemicals from the surplus sugars, fats, oils and carbohydrates produced via commodity byproducts and forestry wastes.
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.
