An improved alkaline earth metal stearate composition is disclosed and is prepared by reacting a fatty acid component including stearic acid and palmitic acid with an alkali hydroxide to form an alkaline soap. An aqueous metal salt solution is then added to the soap, and pH adjusted to less than about pH 8 to form the improved alkaline earth metal stearate. The improved alkaline earth metal stearate provides a substantially pure amount of the dihydrate form of the stearate.

L'invention concerne une composition de stéarate de métal alcalino-terreux améliorée, élaborée par réaction entre une composante d'acide gras à acide stéarique et acide palmitique, et un hydoxyde alcalin, pour la formation de savon alcalin. On ajoute ensuite une solution de sel métallique aqueuse au savon, et le pH est réglé à moins d'environ 8 pour la formation du stéarate considéré, lequel offre une quantité sensiblement pure de forme dihydrate du stéarate.
