Aromastat is a complete system for preservative-free cosmetic and personal care products. Aromastat contains no biocides or typical preservatives. Instead it uses multifunctional agents that have excellent efficacy as biostatic and fungistatic agents.

It can be used as an alternative to traditional preservative blends that are seen as undesirable by the consumer. A special benefit of Aromastat is that it performs superbly at neutral pH, a state where many other alternative materials are ineffective.

Aromastat is compatible with most cosmetic ingredients. However, it can interact with residual iron found in some clay-type compounds (e.g., bentonite, silicates, etc). This interaction with iron may produce a very mild orange color or color shift that is barely perceivable to the eye in most formulations. In cases where the clays are high in iron, the colored compounds may be more perceivable.
