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.
