Imidazolidonyl Urea

Imidazolidinyl Urea is a highly effective, broad-spectrum preservative widely used in cosmetics and personal care formulations. It helps prevent the growth of bacteria, yeast, and mold, thereby extending product shelf life and ensuring safety during consumer use. Known for its stability and compatibility with various cosmetic ingredients, it is particularly useful in water-based and emulsified systems.

INCI Name: Imidazolidinyl Urea

Molecular Formula: C₁₁H₁₆N₈O₈

Alternate Names: Germall® 115, Imidurea

Purity: 99%

Country of Origin: India

Benefits and Uses:

• Provides broad-spectrum antimicrobial protection
• Extends the shelf life of cosmetic and personal care products
• Compatible with most cosmetic ingredients and formulations
• Effective even at low concentrations
• Commonly used in creams, lotions, shampoos, and liquid soaps

How It Works:

• Antimicrobial Action: Gradually releases small amounts of formaldehyde, which inhibits the growth of microorganisms.
• Preservative Stability: Remains effective across a wide pH and temperature range.
• Synergistic Effect: Can be combined with parabens or other preservatives for enhanced protection.

pH and Ideal Temperature Range for Best Use:

• pH: 3.0 – 9.0
• Ideal Temperature: Below 50°C (add during the cooling phase to preserve efficacy)

How to Use Imidazolidinyl Urea:

• Usage Rate: Typically 0.1% – 0.5% of the total formulation weight.
• Application: Add to the water phase or during the cool-down stage (<50°C) of formulation.
• DIY Tip: Pair with a chelating agent (like disodium EDTA) for optimal preservative performance.
