Summary
This branched ethoxylated amine surfactant combines the low-foam properties of isodecyl chains with tunable hydrophilicity via EO units. Its versatility makes it ideal for industrial cleaners, agrochemicals, and metalworking fluids, where balanced solubility and mildness are required. The branched structure enhances compatibility with hydrophobic systems while maintaining biodegradability.
