POL YDIMETHYLSILOXANE (addendum)

摘要

Polydimethylsiloxane (PDMS) (synonyms: dimethylpolysiloxane, dimethicone) is widely used in foods as an antifoaming and anticaking agent. PDMS was placed on the agenda by the Secretariat of the Joint FAO/WHO Expert Committee on Food Additives for consideration of the applicability of the current acceptable daily intake (ADI) of 0-1.5 mg/kg body weight (bw) to the material currently in commerce. This ADI was established at the eighteenth meeting (Annex 1, reference 35). When the Committee reviewed theADI at its twenty-third meeting (Annex 1, reference 50), it stated that this ADI applied to PDMS with 200-300 repeat subunits of [(CH3)2SiO] (weight-average molecular weight range, 15 000-22 000) because of concern that the material of lower molecular weight might be more readily absorbed.
