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.
