Processing Methods & Reference Formulations
A. Perfume
Benzaldehyde is best used as a top note or modifier in almond, cherry, or floral accords. Stabilize using antioxidants as Benzaldehyde is prone to oxidation.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Ethanol (95%) | 78% |
| Distilled Water | 10% |
| Benzyl Salicylate | 3% |
| Benzyl Benzoate | 2% |
| Benzaldehyde | 0.25% |
| Linalool | 1.5% |
| Coumarin | 1% |
| Hydroxycitronellal | 1.25% |
| Alpha-Isomethyl Ionone | 1% |
| Citronellol | 1% |
| Fragrance oils (blend) | 1% |
B. Detergents
Incorporate Benzaldehyde in the fragrance blend and add during the final mixing stage to preserve its volatile nature. Ensure compatibility with surfactants and check pH tolerance.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Linear alkylbenzene sulfonate (LAS) | 12.0 |
| Alcohol ethoxylate non-ionic surfactant (C₁₂–C₁₆) | 8.0 |
