What Is Fragrance Percentage?
Fragrance percentage tells you how much of your product is actually fragrance oil or essential oil. It's the concentration that determines how strong your scent will be. Too little, and nobody will smell it. Too much, and you might irritate skin or create safety issues.
I've seen beginners just pour in fragrance without measuring, thinking "more is better." But it's not that simple. Different products need different concentrations for safety and performance. This calculator helps you get it right the first time.
Understanding fragrance percentages is key to making products that smell great and stay safe to use.
Fragrance Percentage Formula
Percentage Calculation Formula
Fragrance Percentage = (Fragrance Amount ÷ Total Product Weight) × 100
This simple formula gives you the concentration:
- • Fragrance Amount: How much fragrance oil you're adding
- • Total Product Weight: Total weight of your finished product
- • Result: Percentage of fragrance in the final product
Example: 25g fragrance in 500g total product = (25 ÷ 500) × 100 = 5%
Fragrance Percentage Examples
Common Product Concentrations
| Product Type | Total Weight | Fragrance Amount | Percentage | Notes |
|---|---|---|---|---|
| Soy Candle | 500g | 25g | 5% | Balanced scent |
| Beeswax Candle | 400g | 20g | 5% | Stronger wax |
| Glycerin Soap | 1000g | 30g | 3% | Skin-safe level |
| Perfume Oil | 50g | 15g | 30% | High concentration |
These are general guidelines. Always test small batches and check fragrance manufacturer recommendations.
Fragrance Mixing FAQs
What's the difference between fragrance oil and essential oil?
Fragrance oils are synthetic scents, while essential oils come from plants. Both are measured the same way, but essential oils may need lower percentages for skin safety.
Can I use the same percentage for all products?
No, different products have different safe ranges. Candles can handle 5-10%, soaps 3-6%, and perfumes 15-30%. Check product guidelines.
Why do units matter (g vs ml)?
Most fragrances are measured by weight, but some are measured by volume. Using the same unit for both ensures accuracy.
