摘要
Non-ionic surfactants of formula (I) are new: (A is a cycloalkyl-, aralkyl- or aryl-modified rosin gp. or its ester with a polyhydric alcohol; X is -CH2CH2- and/or -CH2CH(CH3)-; n is 1-100; m is 1-5). (I) are surfactants for use as dispersants, wetting or emulsifying agents or dyeing aids, in plant protection and pest control prods., etc. They show improved dispersion behaviour in aq. media, and almost no foaming in spite of good wetting properties. They are easily bio-degradable and resistant to strong acids and alkalis under normal conditions of use. Aq. solns. are very pale to colourless.
