DM HYDANTOIN

Description

DM Hydantoin, also known as dimethylol-5,5-dimethylhydantoin (DMDMH), is a versatile preservative widely used in skincare and personal care products. This synthetic compound belongs to the formaldehyde-releasing preservative family, effectively inhibiting the growth of bacteria, yeasts, and molds in cosmetic formulations.

DM Hydantoin functions by slowly releasing small amounts of formaldehyde over time, providing long-lasting antimicrobial protection. Its efficacy is particularly notable in water-based products, making it a popular choice for leave-on and rinse-off skincare items. The ingredient is typically used at concentrations between 0.1% to 0.6%, depending on the specific formulation requirements.

While DM Hydantoin is generally considered safe when used as directed, it may cause sensitivity in some individuals, particularly those with formaldehyde allergies. Formulators often pair it with other preservatives to enhance its effectiveness and reduce the overall concentration needed. Despite concerns about formaldehyde-releasing preservatives, DM Hydantoin remains an important tool in ensuring product stability and safety, especially in regions where alternative preservatives may be limited by regulations.
