Fate of Alkyl Polyglucosides in the Environment

Alkyl polyglucosides (APGs) belong to the class of green or natural surfactants synthesized from fatty acids and sugars. Growing concerns on toxicity of sulfates and ethoxylates has led to their popularity in personal and home care products. Increasing usage has resulted in higher concentrations in discharge sites or wastewater treatment plants. Studies show that APGs are readily biodegradable in laboratory settings; however, limited data are available on their effects on the environment. In this focused review, we discuss their biodegradation profile and toxicity of the parent compounds and metabolites in aquatic systems.
