Sodium arachidate

Sodium arachidate (CAS 13257-34-6) is the sodium salt of arachidic acid, a long-chain C20 fatty acid soap used as an emulsifier and surfactant.

Where is Sodium arachidate used?

• Personal care: bar soap and cream formulations requiring firm texture and stable emulsion structure
• Textile processing: emulsifying agent in fiber lubricants and finishing baths
• Leather treatment: fat liquoring emulsions that condition and soften hides
• Industrial cleaning: degreasing with high-melting soaps, controlled foam and soil suspension
• It provides controlled foam and soil suspension in heavy-duty environments.

Good to know: Its high carbon chain length makes it structurally distinct where conventional shorter-chain fatty acid soaps fall short in performance.
