The invention relates to a method for producing aluminum salts of cyclic phopshinic acid. According to the invention, cyclic phosphinic acids, such as 1-hydroxydihydrophosphole oxide or 1-hydroxyphospholane oxide, are reacted with a basic aluminum acetate, such as hydroxyaluminum diacetate, in the presence of water and in the absence of polar solvents with heat for a reaction time of 1 to 20 hours.
