Safety and IFRA-Style Notes
Fragrance oils are not used at one fixed percentage for all products. The safe level depends on product type, leave-on or rinse-off use, skin contact area, age group, fragrance composition, supplier documentation, and recommended maximum usage level.
- Use candle fragrance only in candles if it is not approved for skin-contact products.
- Use skin-safe fragrance oil for soap, scrubs, body butter, creams, and balms.
- Use lower fragrance levels for face products.
- Follow supplier safe usage recommendation for each fragrance oil.
- Patch test finished cosmetic products before regular use.
- Do not use fragrance oils in lip products unless specifically suitable for lip use.
- Do not claim fragrance oils cure stress, insomnia, headache, anxiety, disease, or any medical condition.
Fragrance Costing Formula
Fragrance oil can be one of the biggest costs in soap, candles, body care, and diffuser products. Costing helps you price products correctly.
| Cost Item | Include This | Why Important |
|---|---|---|
| Fragrance Oil Cost | Cost per kg or per litre | Main aroma cost |
| Usage Percentage | Soap 1-3%, candles 6-8%, body butter around 1% | Controls cost and safety |
| Wastage | Spillage, testing, residue in beaker, failed batches | Must be included in real cost |
| Testing Cost | Burn tests, stability tests, sample batches | Important before selling |
| Packaging | Labels, bottles, jars, boxes, warning stickers | Part of final product cost |
Common Mistakes
1. Using Same Percentage for Every Product
Soap, candles, body butter, face products, and diffusers all need different fragrance levels.
2. Adding Too Much Fragrance
Excess fragrance can cause sweating, separation, irritation risk, candle smoking, poor burn, or product instability.
3. Not Checking Skin-Safe Use
Not every fragrance oil is suitable for skin-contact products. Check supplier recommendation.
4. Measuring by Drops
Use grams and a digital scale. Drops are not accurate for business production.
5. Ignoring Fragrance Cost
High-cost fragrance oils can change product profit margin significantly.
6. Not Testing Candle Wick
Changing fragrance oil can change candle burning performance.
7. Not Testing Soap Stability
Some fragrances can discolor, accelerate, sweat, or change soap appearance.
8. Using Strong Fragrance in Face Products
Face products need very cautious fragrance use or fragrance-free positioning.
9. No Batch Record
Record fragrance name, supplier, batch number, percentage, and final result.
10. Making Medical Claims
Do not claim fragrance oils cure anxiety, insomnia, headache, depression, infection, or disease.
