With Sodium Lauroyl Methyl Isethionate Control
process onto both hair swatches and a mannequin head to show how the improved deposition of cationic polymers from a H0163 formula with and without Sodium Lauroyl Methyl Isethionate can be discriminated visually. Figure 10 demonstrates that the presence
of a small quantity of Sodium Lauroyl Methyl Isethionate in formula H0163 can significantly improve the conditioning performance on hair swatches and a mannequin head from improved deposition of cationic polymer leading to improved fibre alignment, reduced frizz and a smoother look.
Conclusion In the development of concept formulas to showcase Innospec ingredients, it has been possible to highlight the multifunctional nature of several ingredients in a multifunctional hair and body product while reducing water consumption in the shower. We have shown the enhanced foaming
properties of Sodium Lauroyl Methyl Isethionate combined with Sodium Alpha Olefin Sulfonate, mild sulfate-free surfactant combinations with additional benefits in active deposition. We have also shown the enhanced conditioning performance of Guar Hydroxypropyltrimonium Chloride and Stearamidopropyl Dimethylamine, where Stearamidopropyl Dimethylamine also provides suspension of pearliser. While developing this formula, the end
consumer has always been the focus and here performance and price point have been key to achieving a luxuriously mild and environmentally water friendly formula.
