Water soluble anti-caking ingredients?
We are developing an innovative waterless personal care products, but we face some issues with the stickiness of the powder after we put a perfume (around 0.15%). Moreover we use Sodium Lauroyl Methyl Isethionate as a primary surfactant, which after grinding tends to get sticky on temperatures above 30 degrees celsius, so obviously we need to use some good anti-caking ingredient to ensure excellent flowability of the powder.
A potential solution would be to simply use Sipernat 22 S (Hydrated Silica), but unfortunately it works only for our viscous (gel) products equipped with lotion pump. When we try to use it for our foaming hand soap equipped with foaming pump, it immediately clogs the pump, since it is not water soluble.
So, could you please recommend me some water soluble anti-caking agent suitable for washing products, equipped with foaming pump? Vivastar C200 Glucose made by JRS would be a solution but unfortunately it is too expensive as we need something up to around 3-5 EUR per kg.
Thanks a lot in advance!
