SODIUM DEHYDROACETATE
Is SODIUM DEHYDROACETATE safe for seborrheic dermatitis?
Sodium Dehydroacetate is generally a lower-concern ingredient for seborrheic dermatitis when used in a properly formulated product. Its main job is to protect the formula from microbial spoilage, not to act on the skin's Malassezia population.
No direct human seb derm or exact-name Malassezia evidence was found. Preservative performance and tolerance depend on the full system, concentration and product pH. If a product repeatedly stings or reddens inflamed skin, stop using the finished product.
