Sometimes known as DOP (di-octyl phthalate) is a commonly used plasticizer from the phthalate ester family and has been in use in flexible PVC (Poly Vinyl Chloride) products since the 1930’s in medical and packaging applications. Phthalates have been continuously monitored to ensure that their use is safe as small amounts of plasticizers can leach out of products under certain circumstances. Through the years there has been debates by the scientific community as to the safety of these plasticizers. OmniShield™ NSF Certified Vinyl Food Service Gloves are manufactured without DINP/DEHP/DOP.
