About

A fragrance acetal derived from citral, an EU-declared fragrance allergen requiring declaration on product labels.

Citral ethylene glycol cyclic acetal is a protected form of citral used for enhanced stability while retaining its fresh, lemon fragrance. Citral is an EU-declared fragrance allergen (Annex III). While acetal modification may reduce direct allergenicity, IFRA guidelines require consideration of potential citral release from acetal precursors in finished products.
