Description

C12-15 Pareth-7 Carboxylic Acid is a high-purity, non-ionic surfactant intermediate derived from ethoxylated fatty alcohols. This compound matters for formulators seeking versatile, anionic functionality with excellent emulsifying, wetting, and solubilizing properties in demanding formulations. It is primarily needed by manufacturers in the personal care, cosmetics, industrial cleaning, and textile processing industries to create high-performance, mild, and stable end-products.

Application

• Primary Surfactant & Cleanser: A key raw material in the synthesis of mild anionic surfactants (e.g., sodium laureth carboxylates) for facial cleansers, shower gels, and shampoos.
• Emulsification Agent: Used in cosmetic and personal care creams, lotions, and sunscreens to stabilize oil-in-water (O/W) emulsions.
• Industrial & Institutional (I&I) Cleaning: Employed in formulations for hard surface cleaners, degreasers, and dairy cleaners due to its effective wetting and soil removal properties.
• Textile Auxiliary: Functions as a scouring agent, lubricant, and emulsifier in textile processing and dyeing operations.
• Metalworking Fluids: Acts as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic metalworking fluids.
• Agricultural Adjuvants: Used in pesticide and herbicide formulations to enhance spreading, wetting, and penetration on plant surfaces.
