Iodopropynyl Butylcarbamate (CAS 55406-53-6) is a broad-spectrum preservative and fungicide supplied in Technical Grade as a white to almost white solid that controls molds, yeasts and bacteria in personal care formulations, architectural coatings and wood treatments. In the cosmetics industry, it is a preferred Technical Grade preservative for leave-on and rinse-off products due to its low usage levels. It provides long-term stability and protects formulations from spoilage in humid environments. Beyond personal care, it serves as a powerful antifungal agent in architectural coatings and wood treatments. It is highly resistant to leaching, ensuring the longevity and aesthetic integrity of treated outdoor surfaces.
