Model reactive surfactants based on Bunte salt acetate esters of dodecanol and 1, 12‐dodecane diol have been prepared, with mono‐, di‐ and tri‐functionality, with respect to the Bunte salt group. With the exception of the monofunctional Bunte salt derivative, all these compounds readily polymerise to polydisulphides. When applied to wool fabrics by a pad‐batch procedure, in the presence of sodium sulphite, all of these reactive surfactants gave excellent shrink‐resist properties, although the amount required varied. The trifunctional derivative was the most effective in terms of the minimum concentration required to achieve shrink resistance.
