Dimethyloldimethyl hydantoin / Dmdm Hydantoin / DMDMH 55%
Dimethyloldimethyl hydantoin (DMDMH, CAS 6440-58-0) is an antimicrobial preservative widely used in cosmetics and personal care products. Its core advantage lies in its highly effective antibacterial properties through the sustained release of formaldehyde. It also exhibits strong stability and good water solubility. However, concerns remain regarding safety concerns arising from its formaldehyde-releasing properties.
Chemical and Physical Properties
1. Chemical Structure
DMDMH belongs to the hydantoin family of compounds, chemically known as 1,3-dihydroxymethyl-5,5-dimethylimidazolidine-2,4-dione. Its molecular structure consists of two hydroxymethyl groups (-CH₂OH) and a hydantoin ring, which enables it to slowly release formaldehyde (HCHO), thereby exerting its antimicrobial activity.

DMDMH Core Advantages and Applications:
1. Highly Effective Antimicrobial Preservative
*Mechanism of Action: DMDMH slowly releases formaldehyde to destroy the protein structure of microorganisms, inhibiting the growth of bacteria, mold, and yeast, thereby extending product shelf life.
*Applications: Widely used in rinse-off and leave-on products such as shampoo, conditioner, body wash, and skincare to prevent spoilage caused by microbial contamination.
2. High Efficiency at Low Concentrations
*Compared to other preservatives (such as parabens), DMDMH achieves antibacterial effects at lower concentrations (typically 0.05%-0.2%), minimizing its impact on product formulations.
3. Stability and Compatibility
*Stable to light, heat, and pH fluctuations, DMDMH is compatible with most cosmetic ingredients without affecting product texture, scent, or color.
4. Water-Solubility Advantages
*High water solubility allows for easy, even dispersion in formulations, making it particularly suitable for preservatives in water-based products (such as toners and lotions).
