Description

3-(Octadecylamino)Propane-1,2-Diol is a high-purity, long-chain amino diol surfactant and chemical intermediate. This compound is valued for its unique amphiphilic structure, combining a hydrophobic C18 alkyl chain with a hydrophilic diol and amine functional group, which provides excellent surface-modifying properties. It is essential for manufacturers in the personal care, agrochemical, and specialty chemical industries seeking to formulate stable emulsions, enhance product performance, or synthesize advanced derivatives.

Application

• Surfactant & Emulsifier: Acts as a non-ionic/cationic surfactant in personal care products (creams, lotions) and industrial formulations for creating stable oil-in-water emulsions.
• Chemical Intermediate: Serves as a key building block for the synthesis of quaternary ammonium compounds, betaines, and other specialty surfactants with enhanced properties.
• Agrochemical Additive: Used in pesticide and herbicide formulations to improve wetting, spreading, and adhesion on plant surfaces, increasing efficacy.
• Corrosion Inhibitor: Employed in metalworking fluids and industrial lubricants as a filming amine to protect metal surfaces from corrosion.
• Textile & Leather Processing Aid: Functions as a softener, lubricant, or antistatic agent in fiber treatment and leather finishing processes.
• Pharmaceutical Excipient: Potential use as a lipid component in drug delivery systems like liposomes or nanoemulsions for solubility enhancement.

Quality Control

Our 3-(Octadecylamino)Propane-1,2-Diol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical characteristics is provided with every shipment to guarantee consistency and support your quality assurance protocols.

Storage

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