In this article, several ingredients are reviewed for development of sustainable shampoo formulations. Some of the functional ingredients reviewed are plant-based alternatives to existing, petro sourced ingredients while others are mild, sulfate-free and/ or ethoxylate-free alternatives to existing surfactant systems, thickening solutions for challenging media based on naturally derived polymers and efficacy boosters that reduce the use of non-renewable actives with equal benefit for the consumer.

Cocamidopropyl Betaine

By: B. Grüning, PhD; D. Käseborn; and H.I. Leidrei…

This paper presents the methods for producing cocamidopropyl betaine (CAPB), an important secondary surfactant in cosmetic formulations, household cleaners, dishwashing agents and technical applications. With the widespread use of CAPB, more analytical methods to determine its contetns and byproducts are needed. The authors describe the current methods to determine CAPB purity and other characteristics.

Sodium Laurylglucosides Hydroxypropyl Sulfonate for Sulfate-free Formulations

By: Robert J. Coots, PhD, Colonial Chemical Inc.

The use of sulfonated alkyl polyglucosides (SAPG) to replace lauryl sulfates and lauryl ether sulfates in sulfate-free formulations has previously been discussed. These primary surfactants were created with environmental and human safety in mind. The current paper describes more recent work with this material, specifically focusing on the lauryl version of SAPG.
