Name DMDM hydantoin Description DMDM Hydantoin is a preservative used in a wide range of personal care products, cosmetics, and household items to prevent the growth of harmful microorganisms like bacteria, yeast, and mold. It helps extend the shelf life of products and ensures they remain safe to use over time. As a preservative, it is particularly effective in water-based formulations, which are more prone to microbial contamination. Benefits Keeps bacteria, mold, and other pathogens from growing in water-based products. Considerations • Formaldehyde
DMDM hydantoin works by slowly releasing formaldehyde. Formaldehyde is a carcinogen.
• Acute Toxicity
Harmful if swallowed.
• Skin Irritation
Potential skin irritant or allergen.
• Eye Irritation
Can cause eye irritation in higher concentrations.
• Respiratory Toxin
Can cause asthma or respiratory distress when inhaled (at higher concentrations.) Synonyms 1,3-Bis(hydroxymethyl)-5,5-dimethylimidazolidine-2,4-dione
