Detergent Powder manufacturers for premium powders use precipitated Calcium Carbonate only.
Detergent powder manufacturers due to its characteristics of high water absorption capacity and fluffiness use precipitated Calcium Carbonate. High water absorption makes the powder free flowing and fluffiness makes it look bigger pack.
