The evolution of the carbon abundance at the surface of both components of a mass-transferring (Algol-type) binary is examined. Distinction is made between case A and case B of mass transfer, in view of the different timescales involved. In the mass accreting component thermohaline mixing is adopted when matter with decreasing hydrogen abundance is deposited on the surface. It is shown that at the surface of the loser a very low C-abundance is present, while at the surface of the gainer different regimes occur. On the average the expected C-abundance of the gainer is clearly lower than the solar value, but far above the value at the surface of the loser. The variation in time during the mass-transfer process is compared to the values, derived from observations of several Algol systems. Uncertainties from both the observations and from the limited number of available theoretical models are discussed.
