What it is
This is a biodegradable alternative to EDTA that binds trace metal ions in a formula. By tying up those metals, it helps keep the product stable, preserves color and clarity, and supports the preservative system.
Safety & warnings
Used at low levels and generally regarded as non-irritating; valued for its environmental profile.
Origin & sourcing
Synthetic chelator; the EDDS structure also occurs in nature and is chosen for its biodegradability.
Questions everyone asks
What is a chelating agent for?
It binds stray metal ions that would otherwise degrade the formula, helping it stay stable and effective.
How is it different from EDTA?
It does a similar job but is more readily biodegradable, so it is often chosen for greener formulas.
