Description

Sodium Isononanoate is the sodium salt of isononanoic acid, a branched-chain fatty acid derivative. This versatile surfactant and intermediate is valued for its excellent emulsifying, cleansing, and wetting properties, making it a key component in high-performance formulations. It is primarily used by manufacturers in the personal care, industrial cleaning, and specialty chemical synthesis sectors seeking effective and stable anionic surfactants.

Application

• Personal Care & Cosmetics: Acts as a primary surfactant and foaming agent in facial cleansers, shower gels, shampoos, and shaving creams for its mildness and rich lather.
• Industrial & Institutional (I&I) Cleaners: Serves as a key ingredient in heavy-duty degreasers, metal cleaners, and floor care formulations due to its effective emulsification of oils and greases.
• Textile Processing: Used as a wetting agent and emulsifier in scouring, dyeing, and finishing processes to improve fabric treatment uniformity.
• Emulsion Polymerization: Functions as a surfactant in the production of synthetic latexes for paints, coatings, and adhesives, ensuring stable particle dispersion.
• Lubricant & Metalworking Fluids: Employed as an additive to enhance the emulsifying and anti-corrosive properties of cutting oils and coolants.
• Chemical Synthesis: Utilized as a building block or intermediate in the manufacture of esters, amides, and other specialty chemicals.

Quality Control

Our Sodium Isononanoate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to guarantee compliance with your specifications and industry standards.

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); keep the container tightly sealed to prevent absorption of atmospheric moisture which may lead to caking or reduced efficacy.
