Three Keywords Drivers of ZnO Innovation: Clean, Clear, Consistent

By Lee, James
Translated by Choi, Seolha
September 2025, NO.36

Hi, how are you?

Clean, Clear, Consistent – Sunjin Beauty Science’s ZnO lineup, defined by these three keywords, meets diverse customer needs with innovative solutions: extreme safety that complies with heavy metal regulations, transparent powder without white cast, and dispersions with excellent flowability and dispersibility.

First, we would like to introduce Sunjin Beauty Science’s exclusive ZnO, specifically developed for compliance with the emerging international heavy metal regulations.

Heavy metal regulations for cosmetic ingredients are being strengthened worldwide. In Germany, the lead impurity content limit is already below 2ppm, while in Washington State, USA, under Washington State Law HB 1047, which took effect on July 23, 2023, the lead impurity content limit has been strengthened to 1ppm effective January 1, 2025. This is likely to spread from Washington State to the entire United States.

However, considering the reality that manufacturers may find it difficult to immediately achieve the 1ppm standard, the Washington State Department of Ecology announced the following grace period regulations until December 31, 2026:

• General cosmetics: Lead concentration of 2ppm or below

• Color cosmetics and clay masks: Lead concentration of 5ppm or below

However, this grace period policy is temporary, and ultimately stricter regulations will be applied. Considering these future regulations, Sunjin Beauty Science has already developed high-quality ZnO with low lead content of 1ppm or below, and this product is scheduled to be launched as early as Q4 2025.

In addition, Sunjin Beauty Science’s ZnO is effective for developing sunscreen formulations without white cast, based on transparency resulting from the powder’s uniform particle size and excellent flowability of dispersions due to perfect surface treatment.

At the FLSCC 2025 Sunscreen Symposium, there will be a poster presentation on ZnO with low heavy metal content. Don’t miss this opportunity to see our innovative technology that responds to strengthening regulations firsthand.
