Watched ingredients get highlighted on every product panel you open.
- Where it comes from
- Chemical synthesis. GLDA is made from glutamic acid, an amino acid.
- Why it's in the product
- Help cleansers and preservatives work in hard water, and keep a product clear in the bottle.
- Safety and toxicity
- Not a preservative, and carries no flag. EDTA helps a preservative system work, which is why it used to share the cosmetic preservatives entry; it is a chelator, and since October 2026 it reads as one.
