Beschreibung
Zusammenfassung:	A method for preparing dispersions of solid salts of fatty acids in low polarity liquids where a concentrated mixture of at least 50 percent of the solid salts of fatty acids in a low polarity liquid is subjected to high shearing forces, until the average particle size of the solid salts of fatty acids is less than 3 micron. The dispersion may then be diluted with the low polarity liquid to a lower concentration. The solid salt of the fatty acid is most preferably magnesium stearate, and the low polarity liquid is preferably a polydimethylsiloxane fluid having a viscosity of less than 100 centistoke mm2/s. L'invention concerne un procédé de préparation de dispersions de sels solides d'acides gras dans des liquides de faible polarité dans lequel un mélange concentré d'au moins 50 pour cent de sels solides d'acides gras dans un liquide de faible polarité est soumis à des forces de cisaillement élevées, jusqu'à ce que la taille moyenne des particules des sels solides d'acides gras soit inférieure à 3 microns. La dispersion peut alors être diluée avec le liquide de faible polarité afin d'abaisser la concentration. Le sel solde d'acide gras préféré est le stéarate de magnésium, et le solvant de faible polarité est de préférence un polydiméthylsiloxane liquide d'une viscosité inférieure à 100 centistokes (mm2/s).
