The surface activities and foaming performences of ω-chloro, γ -oxaperfluorodecanoic acid (ClCF) and its mixture with octyltrimethylammonium bromide (C8N) have been investigated. ClCF and the mixture show high surface activity with very low cmc and γcmc. The aqueous solution of ClCF performs good foaming ability. However, the mixture of ClCF-C8N system is quite different from that of perfluorocarboxylic acid and C8N system showing the particular effect of the ω-chloro group.

Key words: SURFACE ACTIVITY, SURFACE TENSION
