A synthetic preservative with limited public research; generally considered safe at low concentrations but may cause irritation in sensitive individuals.

beautyskincarepreservative

In plain English

This is a man-made chemical added to skincare products to stop bacteria and fungi from growing. It helps keep the product fresh and safe to use over time. Because it is a preservative, it is used in very tiny amounts. There isn't a lot of public research on this specific ingredient, so it's less common than better-known preservatives like phenoxyethanol.
