The Ministry of Health, Labour and Welfare (MHLW) of Japan has established the List of Preservatives Allowed in Cosmetic Products under the Standards for Cosmetics. To safeguard consumer health and ensure product quality, the use of specific preservatives is allowed under defined conditions.
The list includes 48 preservatives allowed to use, each accompanied by detailed information such as the Ingredient Name, INCI Name, CAS Number, Maximum Concentration in Ready-for-Use Preparations, etc.
Regulatory Implications of the List of Preservatives Allowed in Cosmetic Products
Before manufacturing, importing, or distributing cosmetic products in Japan, companies must ensure that all preservatives used are included in this list and comply with the specified concentration limits and usage restrictions. It is essential for companies to conduct a comprehensive review of product formulations and verify that preservative levels are within the permitted thresholds.
