Tracking categories (test):
Dibutoxy ethyl phthalate is an organic compound and phthalate ester, baring 2-butoxyethanol groups. Like most phthalates it is nonvolatile, and remains liquid over a wide range of temperatures. Although its water solubility is low, it remains one of the most water soluble of the common phthalates.
Uses
It is used as a plasticizer in polyvinyl chloride, polyvinyl acetate[2] and cellulose acetate. It is resistant to microbial attack.[3]
It is used to improve the collection efficiency of specialized filter papers (IP 1478) designed for bulk particulate and trace element sampling in the atmosphere.[4][5]
Safety
Bis(2-butoxyethyl) phthalate exposure has been associated with reproductive toxicity and endocrine disruption.[6][7]
