Description

Imidazolidinyl Urea is a synthetic, broad-spectrum antimicrobial preservative widely used in personal care and pharmaceutical formulations. Its primary value lies in its effectiveness against a wide range of bacteria and fungi, particularly in combination with other preservatives like parabens, enhancing overall system stability. This makes it a critical component for manufacturers requiring reliable, long-term protection against microbial contamination in water-based products. Key industries that utilize this preservative include cosmetics, toiletries, topical pharmaceuticals, and hair care.

Application

• Cosmetic & Personal Care Preservative: A primary preservative in creams, lotions, shampoos, conditioners, and liquid soaps to prevent spoilage and ensure product safety.
• Topical Pharmaceutical Formulations: Used in medicated creams, ointments, and gels to maintain sterility and extend shelf-life.
• Hair Styling & Treatment Products: Incorporated into mousses, gels, and leave-in treatments to inhibit microbial growth.
• Baby Care Products: Employed in baby wipes, lotions, and shampoos at approved concentrations for gentle preservation.
• Sun Care & Sunccreen Lotions: Helps preserve the integrity of water-in-oil and oil-in-water emulsions against contamination.
• Wet Wipes & Towelettes: Acts as a key preservative in pre-moistened wipes for personal, cosmetic, and household use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the original container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
