Clove Sugar Scrub: A Spiced Jar Worked Out in Grams

A sugar scrub is a jar of kitchen ingredients that smells like a bakery: white and brown sugar, a soft carrier oil and a whisper of clove. It looks simple, and it is, as long as the clove stays a whisper. Here is a 300 gram jar worked out in grams.

Why a quarter percent

A scrub is rubbed in, usually for a minute or two, and its carrier oil is meant to linger on the skin after the rinse. Clove oil is very rich in eugenol, which our published GC-MS report for the bud oil lists at 73.57% by area. The Tisserand Institute gives 0.5% as the topical maximum for clove bud oil, and our dilution guidance for skin use starts there. For a scrub we go to half of that, 0.25%, which brings the eugenol in the jar to roughly 0.18%. That is plenty to scent the whole jar.

The recipe

This is a formulation built from the arithmetic above. The sugar and carrier oil come from a grocery or soapmaking supplier.

Ingredient	Grams	Share
White granulated sugar	150	50%
Brown sugar	50	16.7%
Liquid carrier oil	99.25	33.1%
Clove oil	0.75	0.25%

The clove oil works out to about 0.71 ml at the 1.054 relative density on the Certificate of Analysis we publish for one bud batch, or roughly 14 drops. Drops vary, and at this size the difference between 12 and 16 is the difference between 0.2% and 0.27%, so a scale is worth using. Our carrier oil shortlist can help you choose the base.

Setting up your counter

Everything works best when it is ready before you start. You want a clean, dry bowl, a scale that reads in grams, a dry spoon and a clean jar with a tight lid. Wash and dry the jar well, because even a few drops of water left inside can spoil a scrub. Measure the sugars first, then the carrier oil, and the clove oil last, into the carrier.

Mixing so the scent is even

Whisk the clove oil into the carrier first, then fold that mixture into the sugars. Putting oil into oil before it meets the sugar avoids a strong hot spot on a few grains. Pack the jar, label it with the date and the clove percentage, and store it somewhere cool and dark. This scrub contains no water, so it needs no preservative, but only while it stays dry. A wet scoop or a splash from the shower turns it into a water-containing product that has none. Use a dry spoon, keep the lid on, and keep the jar out of the stream.

What the texture should look like

When it is mixed, the scrub should look like wet sand, glossy and clumping when you press it with a spoon. Brown sugar gives it a softer, caramel color and a gingerbread sweetness that goes surprisingly well with clove. If it looks dry and crumbly, you can stir in a little more carrier oil, a teaspoon at a time. That only lowers the clove percentage, which is fine. What you should never do is add more clove oil to a scrub that smells faint, because the smell will build as the jar rests.

Labelling and gifting

Write the date, the ingredients and "external use, keep dry" on the label. If you are giving the jar away, add the clove percentage and a note to patch test, so the person can decide for themselves. A paper tag and a wooden spoon tied on with string make it a charming gift, and the spoon reminds them to scoop with something dry.

Using it

Try a pea-sized amount on the inner forearm first, rinse, and wait a full day, since reactions to fragrance ingredients can be slow to appear. Use it on arms, legs and feet, and keep it away from the face, lips and any broken or freshly shaved skin. Wash your hands after using it. Skip clove altogether if you have eczema or easily irritated skin, and keep the jar away from children and pets. In a large German clinical dataset, clove oil gave a positive patch test in 1.5% of the patients who were tested with it, so it is wise to be a little careful.

For other projects in the same spirit, our balm and soap posts follow the same low-percentage approach. For the bigger picture on dilution, read our safety basics.

A jar of this on the kitchen shelf, with a dry wooden spoon beside it, makes a thoughtful little gift for anyone who loves a spiced scent.
