Description

Dimethyloldimethyl Hydantoin (CAS NO 6440-58-0) is a versatile and highly effective formaldehyde-release agent, valued for its controlled biocidal action and stability in aqueous formulations. This compound is a critical component for industries requiring reliable, long-lasting preservation against microbial spoilage. It is primarily sought after by manufacturers of personal care products, industrial fluids, and coatings where in-can protection is paramount.

Application

• Personal Care Preservative: A key ingredient in shampoos, conditioners, liquid soaps, and skincare formulations to prevent bacterial and fungal growth.
• Industrial Biocide: Used in metalworking fluids, adhesives, polymer emulsions, and latex paints to extend shelf life and maintain product integrity.
• Paper Mill Slimicide: Effective in controlling slime-forming bacteria and fungi in papermaking process waters.
• Textile & Leather Treatment: Employed in finishing baths and processing liquors to inhibit microbial degradation.
• Oilfield Applications: Serves as a biocide in drilling muds and stimulation fluids to prevent souring and biofilm formation.
• Household & Institutional Cleaners: Provides preservation for concentrated detergent blends and ready-to-use cleaning solutions.
