The new labeling method for water resistance based on ISO1886 has started from December 1, 2022. In addition to SPF and PA labels, water resistance is another essential objective indicator consumers take into consideration when choosing sunscreen products.
Early in 2021, Japan Cosmetic Industry Association (JCIA) participated in the formulation of ISO18861 Cosmetics Sun Protection Test Methods Percentage of Water Resistance (hereinafter the ISO18861), and started to develop Water Resistance Determination Standard for UV Protection Effect (2021) (hereinafter the Standard) based on ISO18861.
On November 11, 2022, JCIA officially announced the Standard would be implemented on December 1, 2022, with two years grace period, and also explained the labeling method for sunscreen products.
