The present invention provides a preservative system having at least one preservative component and at least one oil-miscible glycol component, and cosmetic compositions formulated with the preservative system.

This synergistic preservative effect allows for the use of a reduced amount of the preservative component when formulating a cosmetic composition, which in turn results in a composition with reduced irritation potential and reduced material costs.
