Description

1-Decanaminium, n-Decyl-n-(2-Hydroxyethyl)-n-Methyl-, Propanoate (Salt) is a quaternary ammonium compound (quat) valued for its potent cationic surfactant properties and broad-spectrum efficacy. This chemical is engineered to deliver superior performance as a biocide, emulsifier, and conditioning agent in demanding industrial and personal care formulations. It is a critical raw material for manufacturers in the biocidal products, cosmetics, textile processing, and oilfield chemical sectors seeking reliable, high-performance functional ingredients.

Application

• Biocidal Formulations: Acts as a powerful active ingredient in disinfectants, sanitizers, and algicides for industrial, institutional, and agricultural use.
• Personal Care & Cosmetics: Serves as a conditioning agent and antimicrobial preservative in hair conditioners, skin creams, and other leave-on or rinse-off products.
• Textile & Leather Processing: Used as a softener, antistatic agent, and dyeing auxiliary to improve fabric handle and processing performance.
• Oilfield & Industrial Fluids: Functions as a corrosion inhibitor, emulsifier, and biocide in drilling muds, completion fluids, and industrial water systems.
• Household & Institutional Cleaners: Provides cleaning and sanitizing power in hard surface cleaners, laundry sanitizers, and dishwashing formulations.
• Paper & Pulp Industry: Employed as a debonding agent, retention aid, and biocide to control microbial growth in process waters.

Quality Control

Our 1-Decanaminium, n-Decyl-n-(2-Hydroxyethyl)-n-Methyl-, Propanoate (Salt) is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. A Certificate of Analysis (COA) documenting key parameters such as assay, moisture content, and pH is available upon request to support your quality assurance protocols.

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 and performance.
