About

A small synthetic ingredient used to alter the look of discoloration and adjust formula pH. It has a more noticeable irritation or sensitization profile than basic cosmetic ingredients.

This is a small synthetic functional ingredient used to control pH or formula stability rather than to deliver a headline skincare benefit. Raw-material hazard data include H315, H319, H335. That keeps it usable in some products, but it is less comfortable than simple moisturizers and should be handled with more caution.
