3,9-Diethylidene-2,4,8,10-tetraoxaspiro[5.5]undecane (DETOSU) is a bicyclic ketene acetal derived from the isomeric allyl acetal 3,9-divinyl-2,4,8,10-tetraoxaspiro[5.5]undecane (DVTOSU). As a bifunctional monomer, DETOSU is an important building block for polyorthoesters formed by the addition of diols to the activated double bond of the ...
The European Food Safety Authority (EFSA) and the United States Food and Drug Administration (FDA) [3] have evaluated TBHQ and determined that it is safe to consume at the concentration allowed in foods. [4] The FDA [5] and European Union [4] both set an upper limit of 0.02% (200mg/kg) of the oil or fat content in foods. At very high doses, it ...
