Tide 'Stain Release' causing white grits on clothes

Tide Stain Release left white grit residue on my clothes in the washer.
Does this mean the product was old or spoiled?
Is the granular residue harmful to clothes or skin?
A second soak/rinse in the washer did not fully remove this junk, how much rinsing should it need to get it out?
 
sad
Inappropriate?
