Various chemical substances are used in Kao products, including some that may be harmful to human health and the environment. Strict management of such chemical substances is critical for chemical product manufacturers like Kao. Kao carefully manages chemical substances using various methods such as the PRTR System*1 and a comprehensive management system for chemicals*2.
Substances whose annual use levels in each site were over 1 ton
※Due to the revision of the law in April 2023, the target ingredients have changed, so the aggregation period from April to December
