Dimethyloldimethyl Hydantoin DMDMH - Broad-Spectrum Antibacterial Controlled Formaldehyde Release for Surfactant

Dimethyloldimethyl Hydantoin (DMDMH) is a highly effective, formaldehyde-releasing preservative and antibacterial agent widely used in personal care, cosmetics, and industrial formulations. With CAS number 6440-58-0, it is recognized for its broad-spectrum activity against bacteria, yeast, and mold. DMDMH works by slowly releasing formaldehyde in small, controlled amounts, ensuring long-lasting protection while maintaining product stability and safety within recommended concentrations.

• Broad-Spectrum Preservation: Effectively inhibits growth of Gram-positive and Gram-negative bacteria, yeast, and mold.
• Formaldehyde Release: Provides controlled, sustained antibacterial action through gradual formaldehyde release.
• Compatibility: Works well with a wide range of surfactants, emulsifiers, and other cosmetic ingredients.
• Stability: Remains effective across a broad pH range (3-9) and under various temperature conditions.
• Low Use Concentration: Effective at low dosage levels (typically 0.1-0.3%), making it cost-efficient.

• Cosmetics & Personal Care: Shampoos, conditioners, liquid soaps, creams, lotions, wipes, and sun care products.
• Household & Industrial Cleaners: Detergents, surface cleaners, fabric softeners, and dishwashing liquids.
• Paints & Coatings: As an in-can preservative for water-based formulations.
• Adhesives & Sealants: Prevents microbial degradation in water-based adhesive systems.
• Textile & Leather Processing: Used in finishing baths and auxiliary chemical preservation.

DMDMH is synthesized through the reaction of dimethyl hydantoin with formaldehyde under controlled alkaline conditions. The process involves:

1. Mixing: Combining dimethyl hydantoin with aqueous formaldehyde.
2. Reaction: Conducting the hydroxymethylation reaction at moderate temperature with pH adjustment.
3. Stabilization: Neutralization and stabilization to achieve the desired active content and shelf life.
4. Quality Control: Rigorous testing for purity, formaldehyde content, pH, and microbiological efficacy.

• High Purity & Consistency: Our DMDMH is manufactured under strict quality control to ensure batch-to-batch uniformity.
• Regulatory Compliance: Meets international standards including EU Cosmetics Regulation, FDA, and EPA guidelines where applicable.
• Technical Support: Our experienced team provides formulation guidance, compatibility testing, and regulatory assistance.
• Global Supply Chain: Reliable logistics and on-time delivery worldwide.
• Custom Solutions: Available in various concentrations and blended formulations to meet specific customer needs.
