How to Make & Use Orange Peel Powder for Soapmaking
Learn how to make your own orange peel powder and how to use it in cold process soap recipes.
Do you or your family enjoy snacking on fresh oranges?
If so, save some of those peels for your soapmaking projects!
Orange peel powder adds:
- soft natural color
- label appeal
- loads of flavonoids (antioxidants)
Depending on the texture of the powder used (coarse or fine), it can act as an exfoliant as well.
Tip: Be sure to use organic oranges, since pesticides can be concentrated in the peeling.
When should you add orange peel powder to soap?
You have a lot of options, so I suggest experimenting with each way, to see which one you like best.
I often like to add orange peel powder to the hot lye solution since I feel it gives the finished soap a smoother look.
However, you could also infuse it into your oils, or add to the warmed oils before adding the lye solution.
Still other soapmakers like to stir in the powder at trace. (Doing this will usually lead to the most speckled and exfoliating effect.)
How much should you use?
For orange peel, lemon peel, and grapefruit peel powder, I like to start with around 1 teaspoon PPO.
PPO = Per Pound of Oil in a recipe. (1 pound = 16 ounces = 454 grams)
So if your recipe has a total of 16 ounces of oil, use 1 teaspoon orange peel powder. If it has 32 ounces of oil, use 2 teaspoons of powder. If it has 24 ounces of oil, use 1 1/2 teaspoons powder.
My recipes usually have 28 ounces of oil, so I start with 1 3/4 teaspoon of powder in a batch.

Will orange peels spoil in soap?
As long as you use finely powdered peelings, there’s no need to worry about it spoiling in soap or affecting shelf life.
Large chunks or pieces of any type of food can spoil and/or mold inside of soap though, so stick with a fine powder, or just the zest.
Also be cautious about sprinkling orange zest or powder on top of soap. Food items added to the top of soaps can more easily collect mold in humid areas such as bathrooms.
To be on the safe side, made sure the powder is thoroughly mixed into the soap batter.
How to Make Orange Peel Powder for Soap
Making orange peel powder is very easy!
Before enjoying an orange for a snack, use a box grater or knife to grate or slice off the colored part of the peeling, leaving behind as much of the white pithy part as possible.
If you live in a dry climate, you can air dry the pieces in a single layer on parchment paper.
For normal to more humid climates, I recommend putting the peel in a single layer on a parchment lined baking pan and using an oven set to lowest heat (170 degrees F), checking and stirring every 5 minutes until dried and brittle.
If you have a dehydrator, line a tray with parchment and dehydrate at 130 degrees for several hours, checking and stirring every hour or two.
Run the completely dried and cooled pieces through a coffee grinder to make a powder.
Next, sift through a fine mesh sieve to get a softer and finer powder. Finer powders will leave little speckling in soap, while coarse powders will speckle more.
Store the powder in a small jar and label. Shelf life should be at least one year, or as long as the powder has a citrus scent and nice color.
