Does heat or processing affect fragrance emulsions?

Yes, and this is worth factoring into your process design. Like any emulsion system, fragrance emulsions can break down if exposed to excessive heat or mechanical shear beyond what they're formulated to handle. Before incorporating a fragrance emulsion into a heated process, confirm the product's temperature limits with the supplier and validate stability through your full manufacturing cycle — including any mixing, heating, filling, and cooling steps — rather than assuming it will hold under all conditions.
