title: American Contact Dermatitis Society Contact Allergy Management Program: An Epidemiologic Tool to Quantify Ingredient Usage.
abstract: BACKGROUND
  The usage prevalence of ingredients in topical products is important to dermatologists and industry.
  
  
  OBJECTIVE
  To determine the prevalence of methylisothiazolinone (MI) in various types of consumer products
  
  
  METHODS
  The Contact Allergy Management Program (CAMP) database was mapped and sorted in spreadsheet format to determine the prevalence of MI in various types of consumer products.
  
  
  RESULTS
  Methylisothiazolinone was found in 13.2% of 4660 total products in CAMP. High usage of MI was seen in dishwashing products (64%), shampoos (53%), bathroom/kitchen/all-purpose cleaners (47%), hair conditioners (45%), hair dyes (43%), laundry additives/fresheners/softeners (30%), soaps/cleansers (29%), and surface cleaners/disinfectants (27%). Of the products containing MI, MI alone (without methylchloroisothiazolinone) was most common in makeup products (100%), cleaning/dish/laundry products (>99%), moisturizers (82%), shaving products (78%), sunscreens (71%), and antiaging products (67%).
  
  
  CONCLUSIONS
  The American Contact Dermatitis Society's CAMP is a valuable tool to collect epidemiologic data on the incidence of specific ingredient usage in various types of topical products.
