About

An obscure preservative used to help protect formulas from microbes, with far less public safety history than mainstream systems.

This is an obscure specialty preservative rather than a widely used mainstream system such as phenoxyethanol or organic-acid blends. Preservatives are inherently bioactive, and when public cosmetic safety history is thin, a cautious mid-range score is more defensible than treating it like a bland conditioning agent.
