  • Method Of Improving Quality Of Foam Produced From Concentrated Foaming Hand Wash Compositions Comprising Benzoic Acid Preservative
    Publication number: 20230293396
    Abstract: A method of improving foam quality of foams prepared from a concentrated cleaning composition containing fragrance and benzoic acid includes mixing the fragrance with a hydrophilic solubilizer to form a premix and adding the premix to other ingredients of the concentrated composition. A ratio of fragrance to stabilizer in the concentrated composition is about 1:1 to about 3:1. The concentrated compositions are foamed by diluting with water to form a ready-to-use composition and mixing the ready-to-use composition with air in a mechanical foaming head.
