GERMALL PLUS is a combination of Diazolidinyl Urea and IPBC pre-dissolved in Propylene Glycol for ease of use. This combination exhibits a synergistic preservative effect, which reduces the total active preservative level necessary; provides for complete, broad spectrum preservation against Gram-positive and Gram-negative bacteria, yeast, and mold. Compatible with most cosmetic raw materials. Can be used in a wide variety of leave-on and rinse-off personal care formulations for reliable preservation. Recommended use levels in a finished formulation is 0.1-0.5%. Add at 50�°C or below during the cool down stage of processing. Every cosmetic formulation requires a specific preservative system to meet its individual needs. Therefore, every newly developed or modified product should be challenge tested to assure preservative efficacy.
