Lab Lessons—Wise Words From the Bench With John Carson

Today’s formulators must deliver unique products onto the market, and sustaining a long career in cosmetic formulating often means being able to create these innovative formulas for a number of product categories. No one understands this better than John Carson, who in his 40+ years in personal care formulation has created soaps, baby shampoos, sunscreens, antiperspirants and body washes, just to name a few.

Alternative Ingredients for Sustainable Shampoo Development

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.

Formula Anatomy Deciphered—Chelating Agents

The mechanism for chelation, described as a chelate complex, is based on multiple bonding (polydentate ligand) around a single central atom.
