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.

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.

Hybrid Silicone Powders for Oil Absorption in Cosmetics

Shin-Etsu Silicones of America, a US subsidiary of Shin-Etsu Chemical Co. Ltd., has added two oil-absorbing spherical powders to its KSP line of hybrid silicone powders. The line combines a silicone rubber core with a with a silicone resin shell to provide feel and visual benefits to cosmetic formulations.

Eco-friendly, Nonflammable Liquified Gas Propellant

In response to current and possible future restrictions on hydrofluorocarbon (HFC), Honeywell has introduced a propellant that performs like an HFC but exhibits favorable environmental properties.

Polymer Emulsion for Hardness, Gloss and Adhesion in Water-based Nail Polishes

At the 58th Sepawa Congress in Fulda, Germany, Interpolymer introduced a polymer designed for formulation of water-based nail polishes.

Fine Oat Powder for Oil Absorption and Thickening

Oat Cosmetics has introduced a fine oat powder for use in natural cosmetic products. Superfine Oat Flour (INCI: Avena Sativa Kernel Flour) has shown oil absorption, thickening, gelling and texturizing benefits.

Formula Troubleshooting—Microemulsion Systems

Microemulsions have long assisted the pharmaceutical industry in delivering efficacious levels of an active ingredient to the skin by enhancing the active’s bioavailability, versus traditional solutions and dispersions.

PEG-free Solubilizer for Lipophilic Substances

Symrise has introduced a PEG-free solubilizer for lipophillic substances such as perfume, essential oils, actives and vitamins in pure aqueous and aqueous alcoholic product formulations.

Naturally-derived O/W Emulsifier for Skin Care

Seppic has introduced a vegetable-derived, sustainable o/w emulsifier with a light skin feel.

Opacifier for Creamy Cleansing Applications

Dow Personal Care, a business unit of The Dow Chemical Company has launched an opacifier designed to create creamy, conditioning body washes, shampoos and liquid hand soaps.

Formula Anatomy Deciphered—Chelating Agents

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

Mild Corn-derived Thickener for Surfactant Irritancy Reduction

The Lubrizol Corp.’s Noveon Consumer Specialties has created a naturally derived, mild, nonionic thickener that is said to reduce surfactant irritancy while promoting rich lather.
