Title: Determination of Methylisothiazolinone Concentration in Household Products
Developed under the guidance of Dr. Jordan Womick , Chemistry

Methylisothiazolinone, a known contact skin allergen preservative, is present in household products with unknown concentrations. Studies have observed a correlation between methylisothiazolinone's presence in consumer products and increased likelihood of skin irritation. However, previous literature does not suggest how methylisothiazolinone concentrations vary within and between brands. Liquid chromatography-mass spectrometry techniques were used to confirm the presence of methylisothiazolinone in a variety of dish soaps. Results found that there was a significant difference of methylisothiazolinone concentrations within the same brand of dish soaps. Presently, we are developing a method to detect methylisothiazolinone in dish soaps using electrochemistry.
