Abstract Carboxymethyl carobin samples of different degrees of substitution were prepared from carobin by reaction with monochloroacetic acid in presence of sodium hydroxide in non‐aqueous medium. The derivatives are water‐soluble. Their pastes in water are characterized by non‐Newtonian pseudoplastic behaviour. The apparent viscosity depends on the degree of substitution. The stability of the products at storage increases with increasing degree of substitution.
