TOPIC: SULFATE & DIOXANE FREE SURFACTANTS FOR PERSONAL CARE
Market trends and continuous regulatory updates induce surfactant manufactures to optimize processes and formulators to research practical solutions that can satisfy traditional consumer requirements. These include washing efficiency, dermo compatibility, soft sensorial feel during and after wash, absence of allergic potential and, at the same time, meet ever increasing regulatory requirements.
The incoming restriction of reducing 1-4 dioxane to 1 ppm, already effective for the NY department, as well as RSPO and EUDR regulations, is becoming increasingly challenging for the mass-market industry for cosmetic body detergents and shampoos.
New solutions, Sulphate Free that can easily build up viscosity and foam in presence of relatively low amounts of betaine (0.5-2% A.M.) and NaCl (0.5-1.5%) are now available to the formulator.
The absence of Ethylene Oxide and other precursors of by-products in the manufacturing process makes it free of dioxane, nitrosamines, allergens, and compliant with the latest incoming regulations.
The aim of this paper is to analyze quantitatively and qualitatively the efficacy of new available solutions in terms of cleaning efficiency, mildness on skin, dermo compatibility, rheology, foaming power, foam aspect, and ease of processing.
