Regulatory Compliance
| Region | Max Allowed Level | Notes | Certification Body |
|---|---|---|---|
| United States | - | Nonylphenol Ethoxylates (NPEs) are listed on the Toxic Substances Control Act (TSCA) Inventory. The EPA has issued a Significant New Use Rule (SNUR) for 15 NPs and NPEs, requiring EPA notification and review before any new use or resumption of a discontinued use. The FDA permits NPEs as indirect food additives in adhesives and other food contact materials under 21 CFR 175.105. | TSCA Inventory listing is required. |
| European Union | 0.1% | Highly restricted under REACH Annex XVII. NPEs shall not be placed on the market or used in concentrations ≥ 0.1% for applications like industrial/domestic cleaning, textile/leather processing, cosmetics (except spermicides), and as co-formulants in pesticides. They are also on the REACH Authorisation List (Annex XIV), meaning their use must be phased out unless a specific authorization is granted. | REACH Registration is required. Authorization may be needed for continued use past the sunset date. |
| Canada | - | Nonylphenol and its ethoxylates are listed as toxic substances under Schedule 1 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). The government has implemented Pollution Prevention Planning Notices to achieve a >95% reduction in their use in products like soaps, detergents, and in textile and pulp & paper processing. | Compliance with CEPA 1999 and Pollution Prevention plans. |
| India | - | India currently lacks specific, broad regulations for NPEs in most sectors, though their environmental impact is a recognized issue. The Bureau of Indian Standards (BIS) has formulated a standard for 4-Nonylphenol (IS 17939:2022), but comprehensive restrictions on NPEs are not in place. | BIS certification may be required for specific chemicals. |
| Japan | - | Japan's Ministry of the Environment is designating Nonylphenol Ethoxylates (NPEs) as Class II Specified Chemical Substances under the Chemical Substances Control Law (CSCL). This will require manufacturers and importers to report planned quantities and implement measures to prevent environmental pollution. | Compliance with CSCL, including reporting and technical guidelines. |
| Australia | - | There are no specific restrictions on the use of NPEs in Australia or on the import of products containing them. However, the Australian Industrial Chemicals Introduction Scheme (AICIS) has assessed them and notes they may pose an unreasonable risk to the environment. | Listed on the Australian Inventory of Industrial Chemicals (AIIC). |
| China | - | China has banned the use of Alkylphenol Ethoxylates (APEOs), including NPEs, in sanitary cleaners. Other uses may still be permitted, but regulations are tightening. | Must be listed on the Inventory of Existing Chemical Substances in China (IECSC). |
| Korea, Republic of | 0.1% | Nonylphenol and Nonylphenol Ethoxylates are restricted under K-REACH. Their manufacture, import, sale, or use is restricted in products like household cleaners, detergents, and for textile/leather finishing if the concentration is greater than 0.1% by weight. | K-REACH registration is required for quantities ≥1 ton/year. |
| ASEAN | - | The ASEAN Cosmetic Directive does not currently list Nonylphenol Ethoxylates as prohibited or restricted substances for cosmetic use. However, individual member states may have their own national regulations. | Notification to the regulatory authority in each member state where the product is marketed. |
