A method for the preparation of an aqueous stable premix containing a stannous ion releasing compound useful in the manufacture of an aqueous oral care composition containing a stable stannous ion releasing compound which comprises first dissolving the stannous compound in an aqueous solution of citric acid or its alkali metal salt to prepare the aqueous premix and then adding the premix to the vehicle of the oral care composition.
Cette invention concerne la préparation de solutions aqueuses stables prémélangées contenant un composé libérant des ions stanneux. Ce composé est utilisé dans la fabrication d'une composition aqueuse de soins buccaux, cette composition contenant un composé stable libérant des ions stanneux. Le composé stanneux est tout d'abord dissous dans une solution aqueuse à base d'acide citrique ou de son sel de métal alkalin de manière à préparer la solution aqueuse prémélangée, laquelle sera ensuite associée au véhicule de la composition pour soins buccaux.
