Diethyl phthalate (DEP) is a phthalate ester, namely the diethyl ester of phthalic acid. It is a clear substance that is liquid at room temperature and is only slightly denser than liquid water. It has a faint, disagreeable odor and can be transferred from the plastics that contain it.
Prestige looks at a popular price. A popular choice for sports clubs, soft enamel is a durable, high quality pin that lends itself to enhancements such as spinners, blinkers and danglers. Itâs perfect for simple yet bold designs, with separate areas of bright color.
Extrinsic stains refer to staining of the enamel, the hard surface protecting the more nervous dentin and pulp. Enamel comes into contact with everything you eat or drink, though, and over time it can absorb the pigments left over by these foods and beverages.
