The details

Sodium Dehydroacetate is a synthetic preservative and sodium salt form of dehydroacetic acid . It stops bacteria, mold, and yeast from growing in your products at low concentrations. Clinical testing found it to be non-irritating, non-sensitizing, and non-photosensitizing. It's also not significantly absorbed through skin. There are a very small number of reported cases of contact dermatitis in cases linked to wound-care creams used over compromised skin (rather than skincare). Overall, this is a well-studied and low-risk preservative just doing its job. Typical concentrations run up to 0.6%, which is also the maximum amount permitted under both EU CosIng regulations and US FDA guidelines.
