Which pair names common chemical sensitizers classified as preservatives causing ACD?
Answer
Formaldehyde and methylisothiazolinone (MI/MIT)
Fragrances and preservatives are listed as chemical sensitizers that rank highly as causes of Allergic Contact Dermatitis (ACD). Among the preservatives frequently implicated in causing adverse reactions are formaldehyde (or formaldehyde-releasing agents) and methylisothiazolinone, often abbreviated as MI or MIT. These chemicals are intentionally added to a wide array of personal care items, such as lotions, deodorants, and shampoos, either to prevent spoilage or to enhance longevity. Their constant presence across numerous daily-use products contributes significantly to cumulative exposure and subsequent sensitization.
