What usage rates are recommended for this Sichuan pepper oil?
Recommended usage rates vary by application, with the numbing potency of sanshool dictating low starting doses in cosmetics and skin-contact products.
Recommended Usage Rates
| Application | Rate | Note |
|---|---|---|
| Food flavoring (finished product) | 10 – 100 ppm | Hot-pot essence and seasoning bases 0.01–0.1% |
| Fine fragrance concentrate | 0.5 – 5% | Signature modifier; 2–5% typical |
| Perfume spray (end product) | 0.1 – 0.5% | Based on 10–20% concentrate |
| Cosmetics & personal care | 0.5 – 2% | Heating massage oils at 1–2%; facial formulas ≤ 0.5% |
| Scented candles | 1 – 3% of wax weight | 2% typical in soy wax |
| Soap (cold process) | 0.5 – 1.5% | Disperses well in fragrance-oil phase |
| Aromatherapy massage blend | 1 – 2% in carrier oil | Max 3 drops per 10 ml |
- Always start at the low end: the numbing-heating effect is potent and concentration-sensitive
- For skin-contact products, perform a 48-hour patch test on a small area first
- Standardize with carrier oil or solubilizer before adding to water-based systems
