ABSTRACT
Cosmetics do not need to be sterile, but they must be adequately preserved or protected from microbial contamination and spoilage. When consumers use cosmetic products, they repeatedly challenge the cosmetics with microorganisms in saliva, on dirty hands, and in tap water. Microbial growth may occur in cosmetics and toiletry articles kept in a bathroom and subjected to heat and humidity ( 1 ). These products include mascaras, eye shadows, shampoos, facial powders, and facial lotions (foundations and moisturizers).
