DMDM Hydantoin Bactericide Preservative Cosmetic Preservative

Low Free Aldehydes

Product Description

Product Description
This product is the most commonly used aldehyde sustained-release agent, which has a strong killing ability against gram-positive bacteria and negative bacteria, and also has a certain resistance effect against yeast and other fungi. Due to the strict control of raw material quality from the production source and the strict production process, the appearance of this product is colorless and transparent with lower impurity content. Specifically, the methanol content is far lower than similar products in the industry. While ensuring the general total aldehyde content, the low free aldehyde content is the unique advantage of DMDMH, which makes it significantly higher than other aldehyde sustained-release agents.
Performance Features
High Efficiency

Low concentration with strong bacteria-killing ability; a dosage of 0.10% to 0.40% can effectively inhibit the growth of various bacteria.

Convenience

Water-soluble product that can be added directly into systems during the manufacturing process.

Stability

Unaffected by anionic, cationic, and nonionic surfactants; safe and stable within a pH range of 3.0 to 10.0 and temperatures below 60°C.

Safety

The formulation effect is relatively mild, safe, and non-toxic at the usage concentration, causing no irritation to skin or eye mucosa.

Superior System Protection

Contains no inorganic salts, ensuring no negative impact on the stability of the emulsification system while providing spatial protection.
