Haruharu WONDER products are made with minimum 95% naturally-derived ingredients.

While combining these ingredients, oxidation occurs leading to deterioration in quality, performance, stability, etc.

To prevent oxidation, chemical compound ethylenediaminetetraacetic acid (EDTA) is commonly used by cosmetics brands as a sequestering agent.

However, as a natural skincare brand, haruharu WONDER uses an all-natural sequestering agent composed of water, sodium phytate and ethanol.

The ethanol used in the products is less likely to affect the skin as its quantity is strictly controlled.
