DMDM Hydantoin

Chemical Profile and Overview
DMDM Hydantoin (1,3-Dimethylol-5,5-dimethylhydantoin) is an organic compound belonging to the class of formaldehyde-releasing agents, widely used as an antimicrobial preservative in cosmetics, personal care products, and water-based industrial formulations. It appears as a clear, colorless to pale yellow liquid with a faint, characteristic formaldehyde odor and is readily soluble in water and various polar solvents. Its primary function is to prevent microbial spoilage by providing broad-spectrum protection against bacteria, yeast, and mold, thereby ensuring product stability and shelf life.

Core Advantages of DMDM Hydantoin

1. Broad-Spectrum & High-Efficiency Preservation

   Effectively inhibits bacteria, fungi, and yeast in detergents, cosmetics, and personal care products, with a broad antimicrobial spectrum and rapid action. Ensures long product shelf life (extending to 12-24 months) and prevents microbial contamination during storage and use.
2. Excellent Formulation Compatibility

   Fully compatible with surfactants (SLES, AES, LAS, etc.), emulsifiers, humectants, and fragrances commonly used in 日化 products. No precipitation, discoloration, or performance degradation, requiring no adjustments to existing production formulas.
3. Safe & Eco-Compliant

   Non-irritating to skin and eyes at recommended dosages (0.1%-0.6%). Fully complies with international standards such as EU REACH, US FDA, and China GB, meeting global environmental and safety requirements for cosmetics and detergents.
4. Cost-Effective & Easy to Use

   Water-soluble, simple to add and disperse in aqueous formulations (no additional solubilizers needed). High cost-performance ratio—low dosage achieves optimal preservation effects, reducing comprehensive formulation costs for manufacturers.
5. Stable Supply & Customizable

   Large-scale production ensures consistent supply with stable product quality (purity ≥99%, impurity content ≤0.1%). Supports custom concentration specifications (e.g., 50% aqueous solution, powder) to meet diverse customer formulation needs.
