Guaiyl Acetate, with CAS number 134-28-1, is a synthetic aroma chemical commonly used in perfumery for its pleasant, woody, and slightly floral scent profile. It is often employed in fragrance compositions to enhance the complexity of the scent, providing a soft, elegant character that can complement both floral and woody accords. Guaiyl Acetate typically finds its place in the middle to base notes of a formula, where it can contribute to the overall depth and richness of the fragrance. As a synthetic compound, it offers consistency and stability in formulations, making it a reliable choice for perfumers. While specific safety data for Guaiyl Acetate may vary, it is important for formulators to consider any potential regulatory restrictions or allergen declarations associated with its use, particularly in regions with stringent cosmetic regulations. As with many synthetic aroma chemicals, it is advisable to use Guaiyl Acetate within established safety guidelines to ensure consumer safety and compliance with industry standards. — AI-generated summary, 2026-09-02.
