DC magnetization and AC susceptibility measurements point to the formation of a spin glass state in the ternary spinel-type compounds Li1.33xCo2-2xTi1+0.67xO4. The dynamics of spin freezing was analysed with both the critical slowing down and the thermally activated dynamics models. The parameter values obtained, as well as the behaviour of the zero- field-cooled and field-cooled magnetization as a function of temperature, indicate the existence of a cluster glass state in disordered spinel samples with x = 0.25 and 0.40, and probably also in the ordered spinel with x = 0.50. Ordered spinel samples with x = 0.75 and 0.875 were found to be paramagnetic down to the temperature of 1.7 K with a random distribution of Co2+ ions.
