The efficiency factors are calculated for cylindrical two-layer dust grains with silicate core and ice mantle. For dielectric grains it is found that the core does not have a significant influence on the optical properties of the grain if the ratio of the core radius to the mantle radius is less than 0.1. Expressions are obtained for the efficiency factors in the Rayleigh approximation, and their region of applicability is determined.
