Diazolidinyl Urea (CAS 78491-02-8) is a widely adopted preservative in the cosmetic and personal care industry, prized for its potent antimicrobial action. Its ability to prevent the proliferation of bacteria, yeast, and mold makes it an indispensable ingredient for formulators aiming to maximize product shelf life and ensure consumer safety. As a formaldehyde releaser, it offers a reliable mechanism for preserving aqueous-based formulations.

The primary function of Diazolidinyl Urea is to inhibit microbial contamination. It achieves this by slowly releasing formaldehyde, a well-established antimicrobial agent, into the product. This continuous release mechanism provides sustained protection, making it effective against a broad spectrum of microorganisms. Its compatibility with a diverse range of cosmetic ingredients, including common surfactants, emulsifiers, and active components, further solidifies its position as a versatile preservative. Formulators can confidently integrate this ingredient into various product types without compromising overall formula stability.

The applications of Diazolidinyl Urea are extensive and varied. It is commonly found in skincare products such as creams, lotions, and moisturizers, where it helps maintain product integrity and prevents spoilage. In hair care, it is utilized in shampoos, conditioners, and styling products. Additionally, it serves as a crucial preservative in household items like wet wipes and detergents. Its efficacy at low usage levels, typically ranging from 0.1% to 0.4%, and its stability across a wide pH range (3-9) offer significant advantages for manufacturers looking to optimize both cost and performance.

For those looking to purchase Diazolidinyl Urea, sourcing from reputable manufacturers and suppliers is key. The availability of high-purity material, often at competitive prices from suppliers in China, ensures that formulators can access a cost-effective solution without sacrificing quality. Understanding the specific benefits—broad-spectrum protection, formulation flexibility, and cost-efficiency—allows buyers to make informed decisions that enhance their product offerings.

In summary, Diazolidinyl Urea is an essential tool for formulators, providing robust antimicrobial protection critical for product stability and safety. Its broad applicability and proven efficacy make it a staple ingredient in the personal care industry, and its strategic use contributes significantly to the quality and market viability of finished goods.
