For cosmetic formulators, the selection and application of preservatives are critical for product stability and safety. Diazolidinyl Urea (CAS 78491-02-8) is a popular choice due to its broad-spectrum antimicrobial efficacy. This article provides essential guidelines for its effective use, particularly for those looking to purchase this ingredient from manufacturers.

Diazolidinyl Urea is a formaldehyde-releasing preservative known for its potent activity against bacteria, yeast, and mold. Its primary mechanism involves the slow release of formaldehyde, which disrupts microbial cell functions. For optimal performance, formulators typically recommend a usage concentration of 0.1% to 0.3%. Adhering to these recommended levels ensures adequate preservation without excessive formaldehyde liberation, which is crucial for regulatory compliance and consumer safety.

A key advantage of Diazolidinyl Urea is its remarkable stability across a wide pH range, typically from 0.3 to 9.0. This makes it compatible with a vast array of cosmetic formulations, including those that are acidic or neutral. Furthermore, it can withstand working temperatures of up to 100°C, offering flexibility during the manufacturing process. When purchasing from a China manufacturer, understanding these application parameters is vital for successful integration into your products.

The physical form of Diazolidinyl Urea – a white, fluid powder – facilitates easy incorporation into water-based systems. It is readily soluble in water, which simplifies the formulation process. When considering purchasing this ingredient, it's beneficial to partner with a supplier who can provide detailed technical data sheets (TDS) and certificates of analysis (CoA). These documents confirm product specifications, purity, and adherence to quality standards, assuring buyers that they are obtaining a reliable raw material.

Finally, Diazolidinyl Urea offers a shelf life of two years when stored properly in a dry, draughty, and clean place at room temperature. For companies looking to buy this preservative, understanding these application guidelines ensures that they can leverage its full potential in creating safe, stable, and long-lasting cosmetic products. Our role as a manufacturer is to supply this high-quality ingredient and support your formulation success.
