Sodium laureth-4 carboxylate
Sodium laureth-4 carboxylate, identified by CAS 38975-04-1, is a versatile anionic surfactant belonging to the alkyl ether carboxylate family. It is synthesized through the carboxymethylation of ethoxylated lauryl alcohol, typically containing an average of four moles of ethylene oxide. This chemical structure imparts unique properties, combining the high foaming and cleansing capabilities of traditional anionic surfactants with the mildness and electrolyte stability often associated with nonionic species.
In industrial and research contexts, this material is valued for its exceptional stability across a wide pH range and its compatibility with various other surfactant classes, including cationics. It exhibits excellent lime soap dispersing power, preventing the precipitation of insoluble salts in hard water conditions. As a raw material, it is handled as an aqueous solution or concentrated paste, requiring standard industrial hygiene practices to maintain its integrity and performance in complex formulations.
• In the personal care and cosmetic industry, sodium laureth-4 carboxylate serves as a primary or secondary surfactant in cleansing formulations. Its mild profile makes it particularly suitable for sensitive skin products, baby shampoos, and facial washes, where it provides a rich, creamy lather while reducing the irritation potential of harsher sulfates.
• The compound is frequently utilized in household and industrial cleaning solutions due to its robust performance in hard water. It functions as an effective emulsifier and dispersant, ensuring that oils and particulates remain suspended in the wash liquor. Its stability in acidic or alkaline environments allows for its inclusion in specialized descalers and heavy-duty degreasers.
• Within the textile and leather processing sectors, this material acts as a wetting agent and lubricant. It assists in the uniform distribution of dyes and finishing agents across fiber surfaces, improving the overall quality of the treatment process. Its ability to maintain functionality in the presence of various salts and minerals makes it a reliable component in complex industrial baths.
