Product Description
Dimethyloldimethyl Hydantoin (DMDMH) CAS 6440-58-0
Product Introduction
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.

Product Functions
- 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.
Application Areas
- 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.
Manufacturing Process
DMDMH is synthesized through the reaction of dimethyl hydantoin with formaldehyde under controlled alkaline conditions. The process involves:
- Mixing: Combining dimethyl hydantoin with aqueous formaldehyde.
- Reaction: Conducting the hydroxymethylation reaction at moderate temperature with pH adjustment.
- Stabilization: Neutralization and stabilization to achieve the desired active content and shelf life.
- Quality Control: Rigorous testing for purity, formaldehyde content, pH, and microbiological efficacy.
