In recent years, consumers are inclined towards naturally based, ecologically friendly and sustainable products. Surfactants are a major component of cleaning products and hence there is a shift towards increasing the usage of more natural surfactant technologies. Green labels and sustainability credentials are highly sought after, and many companies try to substitute conventional surfactants with green surfactants like Alkyl Polyglucosides (APG) to avoid using petroleum feedstock. Another green surfactant, Alkyl Ethoxy Polyglucosides (AEG), is a new and improved version of the current APG.

What is Alkyl Polyglucosides (APG)?

APGs are non-ionic surfactants derived from natural fatty alcohols and glucose from renewable plants. They are mild and effective as surfactants in cleaning products.

Key Benefits of APGs

What Is Alkyl Ethoxy Polyglucosides (AEG)?

It is a new non-ionic surfactant where the polyoxyethylene chain was introduced between the alkyl chain and polyglycosides group. Similar to APGs, AEGs are mild, biodegradable and have strong detergency. They also qualify as green surfactants and are RSPO certified, Eco-certified and REACH compliant.
