Large quantities should be avoided as they may have adverse effects on the body. Cosmetic Allergies: High concentrations of cinnamic acid in cosmetics can trigger allergic reactions in some individuals, leading to skin irritations, redness, or itching. Toxicity: If cinnamic acid undergoes conversion to cinnamaldehyde, it can become highly toxic to the body. This transformation can occur under specific conditions or in the presence of certain chemicals. Eye Irritation: Direct contact with concentrated cinnamic acid may cause irritation in the eyes. If eye exposure occurs, rinse thoroughly with clean water and seek medical attention if irritation persists.
Certain groups of people should exercise caution or avoid cinnamic acid: Allergy Sensitivity: Individuals with known allergies or sensitivities to cinnamon or related compounds, like cinnamic acid, should avoid products containing this nutrient to prevent allergic reactions. Sensitive Skin: People with highly sensitive skin should be cautious when using cosmetics or skincare products with high cinnamic acid concentrations, as they may experience skin irritation or allergic reactions. Eye Sensitivity: Direct eye contact with concentrated cinnamic acid should be avoided, as it can lead to eye irritation. In case of accidental contact, rinse the eyes with clean water and seek medical attention if needed. Consult with a Healthcare Professional: If you have underlying medical conditions or are taking medications, it's advisable to consult a healthcare professional before significantly increasing your cinnamic acid intake, especially through supplements, for personalized guidance.
