This study evaluated the effects of natural and synthetic fixatives; Sandalwood Essential Oil and Ambroxane on fragrance longevity, pH stability, formulation integrity, and cost-effectiveness in perfume formulation. Ambroxane showed the slowest evaporation rate (0.010 mg/h), followed by Sandalwood (0.013 mg/h), with the Control evaporating fastest (0.017 mg/h). pH analysis revealed statistically significant differences (p < 0.05), with Sandalwood having the highest pH (7.12). All formulations remained stable under varying temperatures over 14 days. Cost analysis showed Sandalwood-based perfumes were 13.6% more expensive than those with Ambroxane. Overall, Ambroxane demonstrated better longevity and cost-efficiency, making it suitable for large-scale production, while Sandalwood served as a stable, natural alternative. These findings offer valuable insights for selecting optimal fixatives in perfume development.
