Solid emulsion antiperspirant products are described. The antiperspirant products contain a continuous phase including a water-immiscible liquid and a structurant and a disperse phase including an antiperspirant active dissolved in a polar solvent. The disperse phase has a conductivity of less than or equal to about 75 mS/cm at 250C. And the antiperspirant active has a combined peak 4 and peak 5 area percentage of at least about 25% relative to the area sum of peaks 1 to 5. Methods for making solid emulsion antiperspirant products are also described.
L'invention concerne des produits anti-transpirants à émulsion solide. Les produits anti-transpirants contiennent une phase continue comprenant un liquide immiscible dans l'eau et un structurant ainsi qu'une phase dispersée comprenant un anti-transpirant actif dissolu dans un solvant polaire. La phase dispersée a une conductivité inférieure ou égale à environ 75 mS/cm à 25 °C. En outre, l'anti-transpirant actif a un pourcentage combiné des aires de pic 4 et de pic 5 d'au moins environ 25 % par rapport à la somme des aires de pics 1 à 5. L'invention concerne également des procédés de fabrication de produits anti-transpirants à émulsion solide.
