1 Kilogram of Fragrance Oil: How Many Products Does It Make?
"I bought a kilo of fragrance oil; how many bottles of perfume will it make?" It is the question anyone who sells fragrance oil hears most, and the answer is not a single number; it varies tenfold by product. The same kilogram means 60 bottles in perfume, 300 bottles in room spray, and 50 kilograms of soap in soap.
The single variable that determines the answer is the usage rate: the percentage by weight of fragrance oil in the finished product. The rate depends on the product type, the desired scent intensity and the oil's IFRA limit. This article calculates realistic rate ranges for common products and how many products 1 kg of fragrance oil turns into in each.
The basis of the calculation is simple: 1 kg fragrance oil ÷ usage rate = total weight of product that can be made. At a 10% rate, 10 kg of product; at a 1% rate, 100 kg of product. The rest is converting product weight into a number of bottles or units.
Product-by-Product Calculation Table
The table below gives typical rate ranges and the product quantity calculated at the mid value. Use your own rate for your own product; the table is for a sense of scale.
| Product | Typical fragrance oil rate | Product from 1 kg fragrance oil (mid rate) | Approximate units |
|---|---|---|---|
| Perfume (EDP) | 12–20% | 15% → 6.7 kg concentrate+alcohol | 100 ml bottle (~88 g): ~75 units |
| Perfume (EDT) | 8–12% | 10% → 10 kg | 100 ml bottle: ~110 units |
| Body mist | 3–5% | 4% → 25 kg | 200 ml bottle (~180 g): ~140 units |
| Room spray (alcohol/water-based) | 2–5% | 3% → 33 kg | 100 ml bottle (~95 g): ~350 units |
| Reed diffuser | 15–25% | 20% → 5 kg | 100 ml bottle (~95 g): ~52 units |
| Candle | 6–10% | 8% → 12.5 kg candle | 200 g candle: ~62 units |
| Bar soap | 2–3% | 2.5% → 40 kg soap | 100 g bar: ~400 units |
| Shampoo / shower gel | 0.8–1.5% | 1% → 100 kg | 400 ml bottle (~410 g): ~240 units |
| Cream / lotion | 0.3–1% | 0.5% → 200 kg | 200 ml jar (~200 g): ~1,000 units |
| Fabric softener | 0.5–1.5% | 1% → 100 kg | 1 L bottle (~1 kg): ~100 units |
The unit counts in the table are rounded and do not include headspace, waste or samples. A 3–5 per cent waste allowance is normal in production; the real count comes out slightly below the table.
The Calculation for Your Own Product: Step by Step
Five steps are enough to adapt the table to your own product.
- Set the rate
Start from the range for the product type, cap it with the IFRA limit, settle it with an odour test. The rate decision is a matter of product formulation, not of this article; here it is used as a number.
- Find the total product weight
1,000 g ÷ (rate ÷ 100). For 12%: 1,000 ÷ 0.12 = 8,333 g of product.
- Find the unit weight
Bottle volume × product density. 100 ml perfume × 0.88 = 88 g. For candles and soap the weight is given directly.
- Deduct waste
3–5 per cent of the total product weight. 8,333 g × 0.96 ≈ 8,000 g.
- Calculate the units
8,000 ÷ 88 ≈ 90 bottles. Set a few aside for samples and retained samples; the saleable count is around 85.
Interpreting the Number: Cost and Scale
The question "how many products will it make" actually carries two questions: cost and scale.
Cost. If 1 kg of fragrance oil costs 1,500 TL, the fragrance cost per bottle is 1,500 ÷ 75 ≈ 20 TL in EDP, 1,500 ÷ 350 ≈ 4.3 TL in room spray, and roughly 6 TL per bottle in shampoo. The fragrance oil's share of product cost is high in perfume and low in cosmetics; that is why fragrance oil quality sets the price in perfume and does not in shampoo. The cost-in-use article takes this calculation further.
Scale. 75 bottles of EDP from 1 kg of fragrance oil is a season's stock for a small brand; 1,000 jars of cream may be not a season's but a year's. The fragrance oil order quantity is set by the product's rate of sale; buying 5 kg because "it is cheaper per kilo" means fragrance oil that cannot be used up within its shelf life.
A practical rule for a small start: 20 per cent more than the fragrance oil needed for the first run. It covers waste, samples and a second small batch alike; the oil is used up before its shelf life expires.
