Description

1,3-Bis(2-Hydroxyethyl)-5,5-Dimethylhydantoin is a versatile hydantoin derivative widely used as a key intermediate and functional additive. This compound is valued for its reactivity and ability to act as a precursor in the synthesis of more complex molecules, particularly in polymer and personal care chemistry. It is essential for manufacturers in the cosmetics, pharmaceutical, and specialty chemical industries seeking to produce high-performance, stable formulations.

Application

• Cosmetic and Personal Care Formulations: Acts as a mild, non-irritating preservative booster and stabilizer in creams, lotions, and shampoos.
• Polymer and Resin Synthesis: Serves as a reactive intermediate in the production of polyurethane dispersions, coatings, and adhesives.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and other drug substances.
• Industrial Biocides and Preservatives: Functions as a precursor in the manufacture of formaldehyde-release agents for water treatment and material protection.
• Crosslinking Agent: Utilized in textile and leather finishing processes to improve durability and performance.
• Surfactant and Emulsifier Production: A building block for creating specialty surfactants with enhanced solubility and mildness.

Quality Control

Our 1,3-Bis(2-Hydroxyethyl)-5,5-Dimethylhydantoin is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, moisture content, and impurity profiles to guarantee supply reliability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and performance.
