A search for the pseudoscalar meson eta(b) is performed in two-photon interactions at LEP 2 with an integrated luminosity of 699 pb(-1) collected at e(+)e(-) centre-of-mass energies from 181 GeV to 209 GeV. One candidate event is found in the six-charged-particle final state and none in the four-charged-particle final state, in agreement with the total expected background of about one event. Upper limits of Gamma(gammagamma)(eta(b)) x BR(eta(b) --> 4 charged particles) < 48 eV, Gamma(gammagamma) (eta(b)) x BR(eta(b) --> 6 charged particles) < 132 eV are obtained at 95% confidence level, which correspond to upper limits of 9.0% and 25% on these branching ratios.
