A novel series of low‐foaming ethoxylated hydroxysulphobetaines has been prepared by the reaction of polyoxyethylenated stearylamine and sultone, and their structural features confirmed by infra‐red, nuclear magnetic resonance and elemental analysis. These compounds have good surface activity properties, including surface tension and wetting power. Complexes formed between them and acid dyes have greater solubility than the dye alone, decreasing the dye's affinity for nylon fibres, lowering the rate of dyeing and making them suitable for use as low‐foaming levelling agents.
