PIT Versus PIF for the Rational Formulation of Emulsions

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.

Polyacrylate-33 for Thickening and Suspending in Low Surfactant Cleansers

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.

Hyperbranched Polyalphaolefins Enhance Anhydrous Stick Formulations

Hyperbranched polyalphaolefins offer distinctive functional and aesthetic properties due to their branch-on-branch configuration. In anhydrous stick formulations containing polyethylene or other crystalline waxes, the addition of hyperbranched polyalphaolefins is shown in this article to lower pour points by as much as 10C, increase gloss, modify structure and improve formula stability.

Symrise Launches Multifunctional Stabilizer

Symrise has introduced a multifunctional stabilizer for cosmetics that also exhibits antioxidant, soothing and preservative boosting functions.

Feasibility Study of Sago Starch for Perfumed and Cooling Body Powders

In the present article, sago starch-containing perfumed and cooling body powders are formulated and their physicochemical properties for potential skin irritation are examined. The results indicate that sago starch could potentially be used as the main component in body powders.

Deciphering Chelating Agent Formulas

The mechanism for chelation, described as a chelate complex, is based on multiple bonding (polydentate ligand) around a single central atom.

Microchannel Processing: A Novel Approach to Making 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.

Simple Solutions

this issue of Cosmetics & Toiletries magazine features articles that suggest how the right tweaks to some fundamental variables can improve formulations. O’Lenick and Lott, for instance, discuss how solvents can impact SPF values and describe a new ester to improve sunscreen efficacy

Polysorbate 20

Polyoxyethylene (20) sorbitan monolaurate (INCI: Polysorbate 20), is a ubiquitous nonionic surfactant employed in the formulation of countless cosmetic and personal care products.

A Hydrophilic Silicone Elastomer for Broader Formulating Flexibility

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.

Benefits of Borneo Camphor-derived Hydrotropes for 'Natural' Formulations

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.

Formula Troubleshooting: Acrylate-based Thickening

Acrylate-based ingredients have been modified over the past decades, and their benefits are increasingly evident in many industries outside of cosmetics, such as paints, coatings, inks, textiles, etc.
