Deposition from Conditioning Shampoo: Optimizing Coacervate Formation

New techniques are being offered to produce formulations faster and more cost effectively than ever before. Researchers at the Institute for Formulation Science have addressed this challenge by developing robotic combinatorial techniques for the preparation and investigation of complex mixtures.

Hard vs. Soft Quat

Industry expert Tony O'Lenick explores the differences between hard and soft quats; for example, hard quats are incompatible with anionic surfactants whereas soft quats form complexes with them.

Hard vs. Soft Complex

Industry expert Tony O’Lenick discusses surfactants, describing the difference between hard and soft complexes.

Selecting Silicone Surfactants for Personal Care Formulations

Interactions between a silicone surfactant and a fatty surfactant can alter the properties of a formulation. Here, the authors provide a case study of dimethicone copolyols in a shampoo.

Until an Organic Surfactant Exists

Today’s society is becoming more eco-conscious and as such, consumers want to see natural and organic products now—for a reasonable price and labeled clearly. While it is difficult to create a natural and organic skin care product, it is even more so to formulate an organic or natural hair care product.

Mildness Meets Greenness

Alkyl polyglucoside surfactants are obtained from renewable, plant-derived raw materials. Compatibility test results and exemplary formulations presented here show that alkyl polyglucosides enable cosmetic chemists to formulate mild body cleansing formulations that fulfill the new “green” formulation trend and enable the formulation of alkyl sulfate-free and ethoxylate-free cleansing concepts.

Effect of Branching on Surfactant Properties of Sulfosuccinates

Sulfosuccinates, most commonly either ethoxylated or amido products, have been around for a long time and are used to provide foam, detergency and wetting in formulations. In this article, their wetting and foam attributes are evaluated, examining the effect of branching on these key surfactant properties.

Mixed Fatty/Silicone Surfactant Systems

This article investigates some of the interactions between silicone surfactants and fatty surfactants. Mixtures of these two very different classes of materials can be used by the formulator to alter the aesthetics, maximize effects and minimize costs in personal care formulations.

Compass: When Worlds Colide

This issue of Cosmetics & Toiletries magazine looks at the inner and outer worlds of beauty and even delves into the future with a look at what the newest ingredients formulators will use to build formulas of tomorrow.

Bench & Beyond: Branching for Mildness with Sulfosuccinates

This column surveys a few US patents that explore the effects of branching in the sulfosuccinate molecule and the extent of sulfosuccinate branching into new personal care applications.

In reality, fragrance often is the most chemically complicated component of the formulation, and understanding its technical aspects is essential for the creation of an acceptable product.

Fragrance in Emulsion Systems and Surfactant Systems

Fragrance is a complex system of aroma chemicals whose potential to interact with the base in formulated products is reviewed in this article, with a focus on fragrance in emulsion systems and surfactant systems.

Bench & Beyond: New Dimensions for Surfactants

A brief Internet search reveals uses for surfactants in different industries that personal care formulators might find interesting and transferable to personal care applications.

Anionic Interactions with Cationic Gemini Surfactants

The objective of this paper is to expand the study of interactions between anionic and cationic surfactants to specific Gemini surfactants and to investigate whether their interactions depend upon the linkage group between them.

Sulfate-free Cleansers

With proper formulating techniques, sulfate-free cleansers that offer improved mildness and conditioning are possible. This article will present formulations based on alternate surfactant systems to provide the performance required for the specific applications.

Comparatively Speaking: Fatty Surfactant vs. Fluoro Surfactant

Industry expert Tony O'Lenick asks: What is the difference between a fatty surfactant and a fluoro surfactant? Bruce Baker of ICT Chemicals Inc. provides the answer.
