General Description
DMDM HYDANTOIN is a formaldehyde-releasing preservative widely used in the cosmetic and personal care industry to prevent microbial growth and extend product shelf life. It is effective against a broad spectrum of bacteria, yeasts, and molds, making it a reliable choice for maintaining the stability and safety of formulations. Typically used in low concentrations, DMDM HYDANTOIN ensures that water-based products remain free from harmful microbial contamination throughout their usage period.
Uses in the Cosmetics Industry
DMDM HYDANTOIN is incorporated into a variety of cosmetic and personal care products due to its preservative properties:
- Shampoos & Conditioners: Prevents bacterial and fungal growth in water-based haircare products.
- Lotions & Creams: Extends shelf life and maintains product integrity.
- Liquid Soaps & Cleansers: Protects against microbial contamination during storage and repeated consumer use.
- Makeup Products: Used in foundations, mascaras, and other water-containing formulations to ensure product safety.
- Baby Care Products: Applied in very low, regulated concentrations to prevent spoilage.
Its strong antimicrobial action and cost-effectiveness make DMDM HYDANTOIN a commonly used preservative in both mass-market and professional-grade formulations.
Hazards
While DMDM HYDANTOIN is effective as a preservative, there are important safety considerations:
- Skin Sensitization: May cause irritation or allergic reactions in sensitive individuals, especially with prolonged exposure.
- Formaldehyde Release: As a formaldehyde donor, it releases small amounts of formaldehyde, which is a known sensitizer. Regulations strictly limit its concentration in cosmetics to ensure safety.
- Eye Irritation: Direct contact with concentrated material can cause irritation.
- Regulatory Restrictions: Its use is regulated in many regions, requiring careful formulation within approved limits.
When used according to cosmetic regulatory standards, DMDM HYDANTOIN is considered safe and effective for preserving formulations.
Storage & Stability
- Storage: Keep in a tightly sealed container, stored in a cool, dry place away from heat and direct sunlight.
- Stability: Stable in most cosmetic formulations, maintaining efficacy across a wide pH range.
DMDM HYDANTOIN is available in bulk and wholesale quantities, making it a practical choice for manufacturers looking for reliable and long-lasting preservation solutions.
