2012) inappropriately referred to three polymers [polyvinyl acetate phthalate (PVAP), hypromellose phthalate (HMP), and cellulose acetate phthalate (CAP)] as "phthalates" and inappropriately implied that they are "phthalates" simply because they have the word "phthalate" in their names.
In the "Results" of our article, we specifically noted the use of ortho-phthalates (DBP and DEP), which were often found to be used in combination with the phthalate polymers he discussed in his letter [cellulose acetate phthalate (CAP), hypromellose phthalate (HMP), and polyvinyl acetate phthalate (PVAP)].
Phthalate polymers with no known toxicity-- hypromellose phthalate (HMP), cellulose acetate phthalate (CAP), and polyvinyl acetate phthalate (PVAP)--were included in 75 RX products.
