Is Propane-1,2-Diol Alginate (E405) Halal?

MUIS lists E405 (Propane-1,2-Diol Alginate / Propylene Glycol Alginate) as halal. It is derived from plant material and its normal production involves no animal-derived ingredients. The status applies to the additive itself; the finished product still needs its other ingredients checked.

Propylene glycol alginate is an ester of alginic acid with propylene glycol. It functions as an emulsifier, stabiliser and thickener and is more acid-stable than other alginates.
