CAS 6440-58-0 Dimethyloldimethyl Hydantoin (DMDMH) Cosmetic Grade For Shampoos And Conditioners

Description

Dimethyloldimethyl Hydantoin (DMDMH) is a broad-spectrum, formaldehyde-releasing liquid preservative and antibacterial agent. Chemically, it is a methylol derivative of 5,5-dimethylhydantoin. It acts as a slow-release reservoir of formaldehyde, providing long-lasting protection against bacteria, yeast, and molds in aqueous systems. Its effectiveness at low concentrations, combined with its favorable toxicological profile compared to some other formaldehyde donors, makes it a widely used preservative in industries where microbial contamination is a concern.

Key Features & Advantages

• Broad-Spectrum Efficacy: Effective against Gram-positive and Gram-negative bacteria, yeast, and fungi.
• Formaldehyde Release: Functions as a "slow-release" biocide, providing sustained protection and reducing the need for frequent re-dosing.
• Low Free Formaldehyde: Contains very low levels of free formaldehyde, making it less irritating and sensitizing than some alternatives while remaining effective.
• High Water Solubility: Easy to incorporate into water-based formulations.
• Compatibility: Generally compatible with a wide range of surfactants, emulsifiers, and formulation ingredients.
• Cost-Effective: Provides reliable preservation at low use concentrations (typically 0.1% - 0.3%).
