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.

Brooklyn College Researchers Honored for Surfactant Science

A recent scientific article published by two Brooklyn College researchers was honored with the Soap and Detergent Association (SDA) Distinguished Paper Award.

AarhusKarlshamn Presents Surfactants for Shea Formulas

AarhusKarlshamn (AAK) presented two novel surfactants to formulate a range of shea butter-based shampoos and conditioners...

Pseudo-Nonionic Surfactant Complexes in Soap Bars

Pseudo-nonionic surfactant complexes formed between anionic and cationic surfactants improved physical and sensorial attributes of soap formulations. Two complexes are described; one more stable and the other having the lowest irritation potential.

Comparatively Speaking: Sulfate vs. Sulfonate

Industry expert Tony O’Lenick explains the difference between a sulfate and a sulfonate.

Amphoteric Anionic Interactions

A study of interactions between anionic surfactants and amphoteric surfactants in solution demonstrates that betaines and anionic surfactants interact to have positive effects on viscosity, foam and the salt curve.

Kalichem Italia to Present Olive Oil Surfactant, Emulsifier with a New Vegetable Lipoprotein

Kalichem Italia will launch its new new PEG-free surfactant based on olive oil and vegetal hot proteins.

A Brief Review of Polymer/Surfactant Interaction

In this article, the significance of parameters such as correlation length (blob size), micelle structure, comicellization, polymer adsorption conformation and coacervate structure are introduced with relevance to the conceptual appreciation of polymer-surfactant interactions and its bearing on recent advances in conditioning shampoos.

A Novel Presentation of Nonionic PEG Surfactants’ Characteristics

The authors develop data on 10 attributes of 16 naturally derived PEGs and suggest a presentation technique by which the formulator may view two measured attributes simultaneously.

Hydrophobically Modified Inulin: A Novel Polymeric Surfactant and Emulsion Stabilizer

After a short introduction illustrating the basic principles for steric stabilization by polymeric surfactants, the authors describe a novel polymeric surfactant that consists of hydrophobically modified inulin and demonstrate that it is an effective stabilizer for O/W emulsions, suspensions, nano-emulsions and multiple emulsions.

Evaluating Shampoo Foam

There is probably no personal care category that is more competitive than shampoos. With this in mind, formulators of shampoos are asked by marketing to develop products to both appeal to consumers and perform (whatever “perform” means).
