Santal 33* Type Formula StudySantal Trail 11 · GA-020159

The same name does not mean the same scent.

A formula is a set of numbers. Whether those numbers become a good scent can only be known by making it. That is why formulas with the same name can differ widely in quality depending on who made them.

GrassAccord is not a company that only sells formulas. It is run by an affiliate of a working perfumery business. Each formula carries close to 15 years of hands-on perfumery, built through product development for many fragrance brands.

So we make the scent before we publish the numbers. Every formula we sell has been compounded, matured and smelled by a perfumer before it is released.

You can find numbers for less elsewhere. What we give you is the assurance that these numbers become a real scent, and a Study of 20 to 40 pages that explains why.

We do not hand you a formula and walk away. We stay with you until the scent is finished.

Perfumery is more than weighing what is on the page. A material may be new to you, or the scent may drift while it matures. For those moments, you will not be on your own.

• Ask a perfumer directly. Your first paid purchase includes one perfumer’s question credit, answered in the language you choose.
• Understand the materials. The Ingredient Dictionary shows each material’s character and its regulations by region.
• Learn the principles, not just the numbers. Most formulas on the market come as the numbers alone. Each of ours comes with a detailed Study of 20 to 40 pages that explains why each material is there and why in that proportion, so you can understand the fundamentals of scent and build the ability to develop better fragrances yourself.

Scent is more convincing than words. Try a Vetiver Membership formula first and judge for yourself.

The layers you cannot smell shape the texture of a fragrance.

GrassAccord Sfumino is our perfumer’s technique. Materials at 0.02% or less, too little to be smelled on their own, are laid in several layers. Together they soften the seams between accords, round off sharp edges and gently change the character of the dry-down.

Every paid formula’s PDF has a “The Art of Sfumino” chapter showing which materials were used and why. See how it works

What we sell is not the whole of our craft, but a door into it.

The niche perfume formulas we work on professionally are far more intricate and creative than these. A Type formula is a study document, made so you can learn the principles of perfumery through a well-known scent.

So publishing these formulas does not unsettle our own creative work. If anything, we hope more people will learn perfumery by making good formulas with their own hands.

Scent knows no borders and no single language. Each time one more person learns what a good formula is, a bottle of perfume or a candle somewhere in the world becomes a little more beautiful. That the world’s scents grow a little better this way, and that more people come to enjoy beautiful fragrance in their everyday lives: that is what we truly hope for.

No. A Type formula is a study document that GrassAccord developed independently to learn the impression of a reference scent. It does not promise the same scent as the original. It is not the brand’s formula, and we have no affiliation with the brand.

The finished scent also changes with the materials, equipment and maturation time you use.

The formulas are written for people with basic perfumery knowledge. Proportions are given as percentages by weight, so if you can weigh materials on a scale, you can follow them.

If you are just starting, we suggest practising first with a Vetiver Membership formula and the Ingredient Dictionary.

When you create an account, we give you a $10 voucher valid for 14 days. For this formula, your first purchase comes to $49.00.

The voucher is applied automatically at checkout, and you can remove it there if you prefer.

The study document lists every material and its proportion. Materials are bought separately from fragrance material suppliers, and you can look up each one in the Ingredient Dictionary.

Difficulty finding a material is not a reason for a refund, so please check before buying that the materials are available where you are.

Use a perfumer’s question credit to ask a perfumer directly. Your first paid purchase includes one. The answer arrives within two weeks as a PDF report in the language you choose, and a credit can be used for three months from the day you receive it.

Yes. With a formula you have bought, you may make and sell perfumes and other scented products such as candles, diffusers and soaps.

Safety assessment, labelling, product registration, IFRA standards and the laws of every country where you sell are your responsibility. Your products may not use a brand’s name, logo or bottle shape, or be advertised as smelling like a named perfume.

No. Formulas and study documents may not be shared, resold or posted, even for free.

You may disclose a formula to a contract manufacturer or testing laboratory only as far as needed to make or assess your product, and only after they have promised confidentiality in writing.

Nothing is shipped. A few minutes after payment, we email you a PDF download link. How long the link stays valid and how many downloads it allows depend on your membership tier: 7 days and 3 downloads at the starting tier.

If the PDF is not yet ready in your language, this page says so, and you can download the English edition first.

Yes, within 14 days of purchase and before you first download the file. After the first download, a refund is possible only if the file is defective, for example if it will not open or pages are missing, and we cannot fix or resend it within 7 days of being told.

A scent that differs from what you expected, or a change of mind, is not a reason for a refund. For full details, please see the Terms of Service and the refund policy.
