Phenonip is a broad spectrum liquid preservative used in products to prevent bacteria, mold, and fungal growth.  It is most commonly seen in products such as liquid shampoo, lotions, sugar scrubs and lip balms.  It has an excellent toxicological profile, making it a non-irritant to skin, eyes, and mucous membranes in normal concentrations.  The components in phenonip are biodegradable at the low concentrations found in effluent.
