Processing Methods & Reference Formulations
A. Perfume Oil
Use at 0.1–2%, as it adds a warm, floral, slightly metallic note and enhances violet, rose, and powdery accords. Add directly to the perfume concentrate, ensuring it’s well mixed before alcohol dilution for a stable final blend.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Diphenyl Oxide | 0.5% |
| Linalool | 15% |
| Hexyl Cinnamic Aldehyde | 10% |
| Phenylethyl Alcohol | 20% |
| Geraniol | 10% |
| Iso E Super | 20% |
| Hedione | 10% |
| Galaxolide | 10% |
| Dipropylene Glycol (DPG) | 4.5% |
B. Shampoo
Use at low levels as it has a strong floral, violet-like scent that boosts the fragrance profile. Add during the cool-down phase, to prevent volatility loss and maintain fragrance quality.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Water | ~60-65% |
| Sodium Laureth Sulfate | 15% |
| Cocamidopropyl Betaine | 6% |
| Glycerin | 3% |
| Citric Acid | 0.3% |
| Polyquaternium-10 | 0.2% |
| Disodium EDTA | 0.1% |
| Preservative (e.g. Phenoxyethanol) | 0.8% |
| Fragrance Blend | 11% |
| Diphenyl Oxide | 0.2% |
C. Soap
Add during the fragrance phase, when the soap base has cooled to prevent evaporation and scent loss. Blend with other floral or aldehydic notes to create soft, lingering accords in both cold and hot process soaps.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Sodium Palmate | 40% |
| Sodium Palm Kernelate | 25% |
| Water | 15% |
| Glycerin | 5% |
| Sorbitol | 5% |
| Titanium Dioxide | 1% |
| Tetrasodium EDTA | 0.1% |
| BHT | 0.2% |
| Fragrance Blend | ~8% |
| Diphenyl Oxide | 0.2% |
D. Cosmetic cream
Add during the cool-down phase, to prevent volatility and maintain fragrance integrity. Pre-mix with fragrance oils or a solubilizer to ensure uniform distribution in the cream emulsion.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Water | ~70% |
| Glycerin | 5% |
| Cetearyl Alcohol | 4% |
| Caprylic/Capric Triglyceride | 5% |
| Glyceryl Stearate | 3% |
