Stable, free-flowing particulate adjuncts for use in detergent compositions

Ho Tan Tai
TL;DR: A stable, free-flowing, particulate adjunct suitable for use in particulate detergent compositions consists essentially of a liquid, viscous liquid, oily or waxy adjunct absorbed into a granular zeolite material of a particle size distribution of between 50 to 500 µm and having a bulk density of about 450 to 600 g/l as mentioned in this paper.
Patent

Process for production of granular detergent composition having high bulk density

TL;DR: In this paper, a process for producing a granular detergent composition having a high bulk density comprising the steps of: (i) kneading detergent ingredients to form a kneaded solid detergent mixture; (ii) disintegrating the disintegrated detergent mixtures; and (iii) coating the deteriorated granular mixtures with water-insoluble finely divided powder particles having an average primary particle diameter of 10 μm or less.
