Japan issues proposal to classify NPE as Class II Specified Chemical Substance

On 27 October 2023, the Japanese Ministry of Economy, Trade and Industry (METI) issued a proposal to classify poly(oxyethylene) nonylphenyl ether (NPE) as a Class II specified chemical substance according to its Chemical Substance Control Law (CSCL). The proposal mandates that manufacturers and importers to label their packaging with environmental protection guidelines and to submit reports detailing both expected and actual annual quantities.

Class II specified chemicals are chemicals that have been detected (or are expected to be detected) in significant amounts in the environment and are believed to represent a risk of long-term adverse effects to humans and/or the ecosystem. Currently, there are 23 substances in this class, including trichloroethylene, tetrachloroethylene, carbon tetrachloride, and triphenyltin N,N-dimethyldithiocarbamate.

In Japan, NPE is widely used as:

• Wetting, emulsifying, and dispersing agent in textile processing.
• Detergents, dishwashing liquids, and floor cleaners in household and industrial cleaning products.
• Defoaming agent in paper and pulp production.
• Emulsifier and wetting agent in the production of pesticides and herbicides.
• Emulsifier and surfactants in cosmetic products such as shampoos, body washes, facial cleansers, etc.

The consultation on the draft will end on 26 November 2023.
