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.

Characterization of Multilamellar Vesicles for Cleansing Applications
By: Lawrence A. Hough, Denis Bendejacq and Tobias …
In the present article, the authors characterize a multilamellar vesicle (MLV) system used in personal care and verify its structure via X-ray scattering, rheology and fluorescence microscopy. This enabled the study of MLV formation to investigate bulk rheology characteristics. The results are presented here as application-relevant properties.
