GERMAL PLUS

Germall Plus is a broad-spectrum, synthetic preservative system widely used in cosmetic and personal care formulations to prevent microbial contamination and extend shelf life. It is composed of a synergistic blend of Diazolidinyl Urea, Iodopropynyl Butylcarbamate (IPBC), and Propylene Glycol. Germall Plus is especially valued for its effectiveness at low concentrations—typically used between 0.1% and 0.5%—and its ability to provide long-lasting protection against bacteria, yeast, and mold, even in formulations with high water content, which are especially prone to microbial growth.

What sets Germall Plus apart from many other preservatives is its low usage rate, broad compatibility with a wide range of ingredients, and its ability to function effectively over a broad pH range (3–8). It is highly stable and performs well in both oil-in-water (O/W) and water-in-oil (W/O) emulsions, as well as aqueous solutions such as toners, lotions, creams, serums, cleansers, and even some rinse-off products. Germall Plus is non-paraben, non-formaldehyde donor (in practical use levels), and does not require high heat to incorporate, making it an easy and efficient preservative choice during formulation.

Despite being synthetic, Germall Plus is widely used in both mass-market and professional skincare lines because of its unmatched efficacy at minimal concentrations, its low odor, and its lack of significant interaction with other actives. As microbial contamination can render a skincare product unsafe and ineffective, Germall Plus plays a crucial role in ensuring the safety, stability, and integrity of cosmetic products throughout their lifespan.
