FREE from JSD: Dissolution of Soap Scum by Surfactants. Part III. Effect of Chelant Type on Equilibrium Solubility and Dissolution Rate of Calcium and Magnesium Soap Scums in Various Surfactant Systems

Research led by Sumaeth Chavadej from the Petroleum and Petrochemical College at Chulalongkorn University in Bangkok, Thailand, constitutes this month’s free article pick from the Journal of Surfactants and Detergents Editor-in-Chief George Smith. “Removal of soap scum from around the kitchen and bathroom is a problem that has been around since soap was first discovered,” says Smith. The research shows that dimethyl dodecylamine oxide (DDAO; an amphoteric surfactant) in combination with biodegradable chelants enhances the solubility and dissolution kinetics of soap scum, without strong acids that can cause corrosion and environmental concerns in household cleaning products. The article will be available online, free of charge, until Feb. 14, 2016.
