Why Some Soap Loses Its Scent (And Ours Doesn't)

Here is something most people never think about. That bar of soap you bought last week may have been made a year ago.

It is not a scandal. It is just how most soap gets to a shelf. Big batches, made once, warehoused, shipped, distributed, and then it waits. Sometimes for months. Sometimes for a great deal longer than that.

And while it waits, the fragrance is quietly leaving.

Fragrance is a fugitive

Scent is made of volatile compounds, and volatile means exactly what it sounds like. Those molecules want to be in the air, not in the bar. The lightest notes go first, the citrus, the fresh green top notes, the parts that make you close your eyes when you first open the box. Then the heart notes soften. What is left after a long wait is a shadow of what the perfumer intended.

You have probably experienced this without naming it. A soap that smelled wonderful in the shop and disappointing at home. A bar from the back of the linen cupboard that smells of very little at all.

Nobody did anything wrong. Time did it.

What we do differently

Two things, and neither of them is complicated.

The first is the recipe. Our four fragrances, Basil and Neroli, Lime Basil and Mandarin, Gardenia, and Sandalwood Bergamot and Cedar, were created specifically for us and belong to nobody else. We do not buy them off a list. That means when we make a batch, we make exactly the same thing we made last time, and the time before that. No reformulating, no substituting, no drift. The bar you buy in November smells like the bar you bought in March, because it is the same bar.

The second is size. We make in small batches, never more than one hundred to two hundred kilograms at a time. That is a modest amount of soap. It is deliberately modest.

Because a small batch does something a large one cannot. It sells through. By the time we are running low, we are already making more, and the soap in your hands has not been sitting anywhere for very long at all. It goes straight from us to you, and the fragrance never gets the chance to wander off.

Triple milled, which helps too

Our bars are triple milled, pressed three times until the soap is smooth and dense. That density is why the bars last so long in the shower, but it does something else as well. A tightly pressed bar holds its fragrance closer than a loose, airy one. Good soap making and good scent keeping turn out to be the same craft.

The point of all this

We could make ten times as much at once. It would be cheaper per bar and a great deal less work.

We do not, because the first thing you do with a new bar of soap is lift it to your nose. That moment is the whole thing. If it is not wonderful, nothing else we did matters very much.

So we keep the batches small, the recipes unchanged, and the soap moving.

One more thing. On the first of every month we send one email, and one subscriber somewhere in New Zealand gets a trio of our naked soaps in the post. Drawn at random, no purchase needed. If you would like to be in it, you can join us here www.rabbitrabbit.nz (just scroll down to "SAY RABBIT RABBIT"
