NOPE
Can I eat powdered laundry detergent?
No, eating powdered laundry detergent is a terrible idea and will wreck your insides.
Powdered laundry detergent is made of chemicals that are toxic if ingested. Eating it can cause burning in your mouth, stomach pain, vomiting, and even more serious health problems. If you or someone else accidentally eats detergent, call poison control immediately and seek medical help. This stuff is for clothes, not your digestive system.
If ingestion occurs, call poison control or seek emergency medical care immediately. Do not induce vomiting unless instructed by a professional.
