Sodium Laurylglucosides Hydroxypropyl Sulfonate for Sulfate-free Formulations
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.

Assessing the Safety of Parabens: Percutaneous Penetration and Risk Analysis
In cosmetics, parabens are widely used due to their low cost and efficacy. In recent years, however, some reports have claimed that these materials exhibit estrogenic activity, which has led to attempts to replace them in formulations. This article reviews penetration studies of parabens spanning the past 20 years to determine whether they pose a risk to human health.

Sulfate vs. Sulfate-free: Information to Make a Choice
In the present article, the author considers factors for sulfate vs. sulfate-free formulating, including cost, foam and viscosity. In addition, two test formulations with and without sulfates are compared. The author concludes that little sound science exists to support the current “sulfate-free” market trend, especially when considering the potential benefits sulfates can impart in formulations.

Cocamidopropyl Betaine
This paper presents methods for producing cocamidopropyl betaine (CAPB), an important secondary surfactant in cosmetic formulations, household cleaners, dish-washing agents and technical applications. However, with the widespread use of CAPB, more analytical methods to determine its contents and byproducts are needed. These authors thus describe methods to determine CAPB purity and other characteristics.
Preservation
Ingredient Profile—Benzoic Acid/Sodium Benzoate
Benzoic acid (BA) is a leading choice due to its long and successful history of use preserving foods, drugs and cosmetics. Affirmed as GRAS (Generally Recognized As Safe) by the US Food & Drug Administration (FDA), BA and its sodium salt, sodium benzoate (NaB), are perhaps the most globally acceptable preservatives that have managed to avoid the controversy associated with many of the industry’s tried-and-true preservatives.

Sugar and the Quest for Sulfate-Free Formulations
Many approaches have been tried over the years to eliminate lauryl sulfates and lauryl ether sulfates from personal care formulations, most of which have not been cost-effective. This article discusses a new class of patented anionic products based upon sugar raw materials.
