Description

Diazolidinyl Urea is a broad-spectrum, formaldehyde-releasing antimicrobial preservative widely used in personal care and cosmetic formulations. Its primary value lies in its effectiveness against bacteria, yeast, and mold at low concentrations, ensuring product safety and shelf-life stability. This compound is particularly essential for manufacturers of water-based products such as shampoos, lotions, creams, and liquid soaps who require reliable, long-lasting protection against microbial contamination.

Application

• Cosmetic & Personal Care Preservative: Primary preservative in shampoos, conditioners, liquid soaps, body washes, and skin cleansers.
• Skincare & Haircare Formulations: Used in creams, lotions, moisturizers, and hair styling products to prevent spoilage.
• Wet Wipes & Topical Preparations: Provides antimicrobial efficacy in pre-moistened wipes (baby, cosmetic, household) and topical gels.
• Pharmaceutical Topicals: Acts as a preservative in non-sterile topical ointments, creams, and dermatological preparations.
• Industrial Applications: Used as a biocide in water-based industrial fluids, adhesives, and latex emulsions.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking.
