Description

(3-Hydroxypropyl)Urea is a versatile bifunctional organic compound that combines the reactivity of a primary alcohol with the hydrogen-bonding capacity of a urea moiety. This unique structure makes it a valuable intermediate for synthesizing specialty polymers, modifying biomaterials, and serving as a key building block in personal care formulations. It is particularly sought after by manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries for applications requiring moisture regulation and polymer cross-linking.

Application

• Cosmetic & Personal Care Formulations: Acts as a highly effective humectant and moisturizing agent in skin creams, lotions, and hair conditioners.
• Pharmaceutical Intermediates: Serves as a key synthon in the production of active pharmaceutical ingredients (APIs) and prodrugs.
• Polymer & Resin Modification: Used as a cross-linking agent or chain extender in polyurethane, epoxy, and other specialty polymer systems to enhance properties.
• Biomaterial Engineering: Employed in the surface modification of biomaterials to improve biocompatibility and cellular adhesion.
• Adhesive & Coating Additives: Functions as a modifier to improve the adhesion, flexibility, and moisture resistance of industrial adhesives and coatings.
• Textile & Leather Processing: Utilized as a softening agent and finishing chemical to impart desirable tactile properties.

Quality Control

Our (3-Hydroxypropyl)Urea is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting purity, physical characteristics, and safety data are provided with every shipment to guarantee traceability 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); ensure the container is kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which may affect quality.
