Note on candle fragrance load: The 6% figure is a safe starting point for most wax types. Paraffin typically holds 6–10%, soy wax 6–8%, and coconut wax up to 10%. Always do a test pour before scaling up.

Safe dilution rates for essential oils when used on skin. These are general guidelines — always check individual oil safety data.

Facial products
0.5–1%
Serums, face creams, under-eye products. Sensitive area — stay minimal.
Sensitive skin
1%
Elderly, children (3+), pregnancy. Some essential oils are not safe in pregnancy at all.
Daily body care
2–3%
Lotions, body oils, massage oils for regular use. Most commonly used range.
Targeted massage

How to Use This Perfume Blender Calculator

This tool is built for DIY perfumers, soap makers, candle crafters, and anyone formulating their own fragrance products at home or at a small-batch level. It covers four main things: building a note pyramid, calculating your fragrance load by product type, breaking down exact oil quantities per batch, and looking up safe dilution percentages.

The note pyramid and why it matters

A fragrance has three structural layers — top notes, middle notes, and base notes. Top notes hit you first but fade quickly (usually within 20–30 minutes). Middle notes, sometimes called the "heart," define most of what you smell for the next hour or two. Base notes anchor everything — they last the longest and give the fragrance depth and longevity.

There is no single correct ratio, but a common starting point is 20–30% top notes, 40–60% middle notes, and 15–25% base notes. Enter your oils and their percentages in the Note Pyramid tab. The calculator will warn you if your total goes over or under 100%.

Fragrance load — how much oil to add

The fragrance load is the percentage of fragrance oil relative to your total batch. Get it too low and the scent barely registers; too high and you risk irritation, poor performance, or wasted material. The Fragrance Load tab has standard ranges for the most common product types pre-loaded. Just change the batch size and product type, and the calculator handles the rest.

Common oils used in each note tier

Fragrance oils vs essential oils

Essential oils are extracted directly from plants — steam distilled, cold pressed, or CO2 extracted. Fragrance oils are synthetic or semi-synthetic blends, typically more affordable and often more stable in finished products like candles and soaps. Both can work well depending on what you are making. Essential oils come with more safety restrictions (especially during pregnancy), while fragrance oils require checking IFRA guidelines.
