Are cooling agents harmful to the human body?

Cooling agents are harmless when used appropriately, but excessive or improper use may cause irritation or allergies. Cooling agents (such as menthol and menthyl lactate) produce a cooling sensation by activating cold receptors in the mouth or skin. They are widely used in food, daily necessities, and other fields. Their safety must be comprehensively assessed based on their specific ingredients, dosage, and usage scenario.

Safety of Cooling Agents
Appropriate use is a prerequisite for safety. Cooling agents must comply with national or international standards (such as those set by the FDA and EFSA) for their addition. For example, the permitted concentration of menthol in food is generally 0.1%-1%, which is within this range and does not have negative health effects. Research shows that under normal use, cooling agents are metabolized and excreted from the body, and do not accumulate toxicity.
