Description

Trimethyl-3-[(1-Oxooctadecyl)Amino]Propylammonium Chloride is a high-purity quaternary ammonium compound valued for its cationic surfactant properties and excellent conditioning effects. This compound is essential for formulators requiring a substantive, positively charged molecule with a long hydrophobic chain for surface modification and deposition. It is primarily sought by manufacturers in the personal care, textile, and specialty chemical industries for its ability to impart softness, antistatic properties, and substantivity to various substrates.

Application

• Hair Care Formulations: As a key conditioning agent in shampoos, conditioners, and hair masks to provide detangling, smoothness, and manageability.
• Fabric Softeners & Textile Auxiliaries: Imparts a soft hand feel and reduces static cling in textiles and laundry care products.
• Personal Cleansing Products: Used in body washes and facial cleansers for its mildness and skin-conditioning benefits.
• Industrial Surfactant: Functions as a cationic emulsifier, dispersant, or antistatic agent in various industrial processes and formulations.
• Biocide & Preservative Synergist: Can enhance the efficacy of certain antimicrobial formulations due to its membrane-disrupting properties.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
