• Cost-Effective: Requires significantly lower dosage compared to traditional preservatives like parabens, reducing overall formulation costs by more than half.
• Superior Compatibility: Maintains stability and efficacy in the presence of proteins, cationic, anionic, and nonionic surfactants.
• Wide pH Range: Remains effective across a pH range of 4 to 9, ensuring performance in weakly acidic, neutral, and alkaline environments.
• Excellent Solubility: Highly water-soluble (25g at 25°C), allowing for straightforward incorporation into aqueous systems without complex preprocessing.

Industrial Applications

This product is extensively utilized in industrial circulating water, papermaking pulp, coatings, plastics, and cosmetics. In personal care products such as creams, lotions, and shampoos, it acts as a robust preservative to prevent spoilage and ensure consumer safety. The recommended addition amount for daily chemical products is generally between 0.2 to 0.5‰, with a maximum allowable limit of 1‰. Furthermore, it is employed in cooling water circulation systems for sterilization, mildew prevention, anticorrosion, and algae control. Notably, the compound degrades without leaving harmful residues, minimizing environmental impact upon discharge.

Storage and Handling

To maintain optimal quality, store this product in a cool, dry environment away from direct sunlight, as exposure may cause discoloration. It is stable under acidic to neutral conditions but may decompose under high temperature or strong alkaline conditions. Avoid contact with substances containing -SH groups (such as cysteine) and metal aluminum, as these can reduce antibacterial activity. Always keep away from toxic and harmful substances to prevent contamination. Proper handling ensures the longevity and efficacy of this essential speciality chemical.
