Question
A four-year-old child accidentally drank water containing detergent from a thermal cup. By the time it was discovered, several days had passed, the outer packaging had torn, but the inner layer was still intact, and there were still bubbles underneath. The customer service was informed that it was activated carbon, but it was actually black powder with no odor. The child currently shows no symptoms.
Answer
Based on your description, a four-year-old child accidentally ingested detergent from a thermal cup. Detergents typically come in three types: calcium oxide drying agent, montmorillonite drying agent, and silicone gel drying agent. Calcium oxide drying agents are corrosive, while the latter two are harmless to humans. If the detergent is food-grade, it is also harmless to the body. I hope these suggestions are helpful to you, and wish you good health.
