Bakuchiol, a meroterpene of plant origin, is examined here for its ability to stabilize retinol and polyunsaturated lipids. It was found to be approximately 60-fold more effective than natural tocopherol, under both photo-oxidative and singlet oxygen environments. An overview of retinol stabilization, lipid peroxidation and the unique role lipid peroxides play in biology also is included.

Gel networks are at the base of many modern skin care products and hair conditioners, and their formulation is fairly straightforward. During the Cosmetics & Toiletries Summit, George Deckner and Anthony J. O'Lenick, Jr., will present, in hands-on formulation workshops, the practical aspects of gel network-based o/w emulsions for skin and hair care.

Silicone elastomers for personal care have evolved from cross-linked silicone polymers in silicone fluid carriers, to materials with broader organic compatibility in organic solvents. Recently, hydrophilic properties have been added, which are shown here to enable the incorporation of high levels of water, polar solvents and actives while maintaining organic compatibility and unique sensory characteristics.

Described herein is a hydrophobically-modified acrylic copolymer, polyacrylate-33, which is designed for low-to-medium surfactant-containing cleansers. The ingredient is shown to display high thickening efficiency and good suspension properties and shear-thinning rheology in sulfate-based and sulfate-free chassis. Further, it enables transparent formulations in the presence of salt with improved foaming and sensorial properties.

This article deliberately pushes the boundaries for cosmetics scientists, showing how the much-used phase inversion temperature (PIT) technique is a limiting special case of a more versatile, rational approach to surfactant optimization: HLD-NAC. This simple way of understanding the basic interactions within emulsion formulations can be generalized to create totally new ways of formulating stable emulsions.

In the present article, microchannel emulsification is explored as a process method that precisely adds a dispersed phase into a continuous phase through an engineered dispersion plate. This approach is shown to produce emulsions with smaller droplets having tighter size distributions than conventional means, which leads to stable products with the limited need, if any, for surfactants.

Alpha-pinene, typically derived from pine trees, is also a by-product of the paper manufacturing process. The material is a source of low-toxic and naturally based isobornyl ethers, from which a new hydrotrope, dipropylene glycol isobornyl ether, was developed.The present study examines the unique dispersion and solubility properties of this material, among other benefits, and its application in cosmetics.
