Reports from China Surfactant Net and European chemical market intelligence provider ICIS indicate that the EU's new REACH regulations on green auxiliaries and China's updated standards for daily chemical and agricultural chemicals have taken effect, imposing mandatory limits on biodegradability and skin irritation for petroleum-based surfactants. The new rules restrict the use of high-residue chemical surfactants in applications such as cleansers, pesticides, and oilfield remediation. Rhamnolipid produced via microbial fermentation is fully biodegradable and minimally irritating to skin, and is now being recommended by industry guidelines in multiple countries as a green alternative raw material, helping downstream enterprises achieve environmental compliance.
