Description

Trimethyl-3-[(1-Oxooctadecyl)Amino]Propylammonium Dimethyl Phosphate is a quaternary ammonium phosphate ester salt, a specialized cationic surfactant with unique emulsifying and conditioning properties. This compound is valued for its ability to impart antistatic and softening characteristics in various formulations, bridging the performance gap between fatty quats and phosphate esters. It is primarily sought by manufacturers in the personal care, textile treatment, and industrial surfactant sectors for developing high-performance specialty products.

Application

• Hair Care Formulations: As a conditioning agent in shampoos, conditioners, and hair masks to provide excellent detangling, softness, and manageability.
• Fabric Softeners & Textile Auxiliaries: Used to impart a soft, smooth hand-feel to textiles and as an antistatic agent in fabric care products.
• Personal Care Products: Serves as an emulsifier and skin-conditioning agent in lotions, creams, and other leave-on or rinse-off formulations.
• Industrial Surfactant Blends: Incorporated into specialty surfactant systems for its cationic activity, emulsification, and corrosion inhibition properties.
• Agricultural Adjuvants: Potential use as a component in pesticide or herbicide formulations to enhance spreading and adhesion on plant surfaces.

Quality Control

Our Trimethyl-3-[(1-Oxooctadecyl)Amino]Propylammonium Dimethyl Phosphate is manufactured under a strict quality management system. Each batch is tested to ensure consistent composition, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and key physical parameters is provided with every shipment to guarantee it meets your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality.
