Final answer:
Shampoos, detergents, and perfumes are three products that have scent uniformity and protect against odors.
Step-by-step explanation:
Three products that have scent uniformity and protect against odors are shampoos, detergents, and perfumes.
Shampoos often contain carbonyl compounds like cis-3-hexenal, which give them a green herbal odor and help protect against odors.
Detergents can have ingredients like optical brighteners, fabric softeners, and perfumes that contribute to their odor uniformity and odor protection.
Perfumes contain fragrant essential oils, fixatives, and solvents, and are designed to give off an agreeable scent while also protecting against odors.
