The Ministry of Environment has announced import restrictions on detergents containing nonylphenol and nonylphenol polyethoxylate due to their harmful environmental distribution and risks to human health. To provide importers time to adapt, the restrictions will be implemented in two phases. The first phase, effective from September 1, 2026, prohibits the import of detergents with a nonylphenol or nonylphenol polyethoxylate concentration of 5% or more. The second phase, starting on March 1, 2027, lowers the allowable concentration to 0.1% to further safeguard environmental safety.

In line with updates to the classification and management of toxic chemicals, the Ministry highlighted that nonylphenol and nonylphenol polyethoxylate are persistent in the environment, exhibit bioconcentration, and can harm aquatic ecosystems. Once these substances enter the food chain, they pose significant health risks to humans.

Previously, in 2008, the Ministry banned the use of nonylphenol and its derivatives in the production of household cleaners. This latest regulation aligns with the European Union’s REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) standards, specifically its Substances of Very High Concern (SVHC) list. The adjustment lowers the permissible concentration from 5% to 0.1% (w/w).

Nonylphenol and its derivatives are commonly used as nonionic surfactants in detergents. However, a variety of alternative surfactants, such as alkyl polyglycosides, betaines, and alkyl glucosides from natural and synthetic sources, are available. The phased implementation of the restrictions is designed to minimize disruption to domestic importers while achieving environmental and health protection goals.
