Can Sweet Almond Oil Be Used In Soap Making?

Sweet almond oil can be used in cold process soap making around 5 to 20%. It saponifies easily and produces a rich conditioning and stable lather. It’s a lightweight, moisturizing oil, easily absorbed by skin, due to its content in linoleic and oleic fatty acids.

People with a nut allergy should be careful in using sweet almond oil, as even in soap it can cause allergic reactions. Perform a patch skin test before using sweet almond oil in your homemade products, just to be sure.

My only struggle with using sweet almond oil in soap and other natural products has been with rancidity. It’s an oil that easily turns rancid, in my personal experience, and requires an anti-oxidant, no matter how fresh it is.

100% Sweet Almond Oil Soap

But we are going to challenge these soap making rules, by making a 100% sweet almond oil soap. Single-oil soaps are my favorite as they are less complex, requiring few ingredients to make, and being more economical for that. Using this post as a guide, sweet almond oil makes up for a very good soap bar. It results in a creamy colored, shiny, hard bar, odorless, with strong lather and nicaly conditioning.

My experience with single-oil soap bars has been really good. I ellect these recipe as ideal for beginners to start soap making, to avoid the long, discouraging list of oils from other recipes. When you are just starting, checking if making soap at home is your thing, there’s nothing worse than looking at a list of many ingredients you don’t have at home.


Besides, let’s not forget the economical side of the thing. By choosing the cheapest oil available for you locally to make soap, turns soap making into a viably economical activity, where you can even compete against over-the-counter hygiene products.

There’s no need to to purchase coconut oil and olive oil and castor oil and sunflower oil and spend money in all those oils just to make soap. In some regions of the globe, these oils are actually very expensive and/or difficult to find.

Here are my other single-oil recipes, they can all be found in the “Soap Recipes For Beginners” category:


What Is The Function of Citric Acid In Soap Making?

Citric acid is used in soap making as a chelator (avoids soap scum), and to help prevent rancidity and DOS (Dreaded Orange Spots).


Going back to the former, chelation is the ability of a substance to bond with metal molecules. Especially with hard waters, soap can react with mineral (metal) substances, like calcium or magnesium, creating this white build-up substance – soap scum – that covers your shower walls or faucets. It also reduces the soap ability to lather and clean properly. Using a chelator, the metal molecules react with the chelating substance instead, and no longer with soap.

Rancidity and DOS

About the later, this is the reason why I’ve started considering the usage of citric acid in soap, and studied in more detail (this post was my main reference). I have had some bad experiences with DOS and rancidity in lard and olive oil handmade soaps. I’ve used sweet almond for oil infusions and without vitamin E oil it got rancid as well. There’s nothing more frustrating than your wonderful soap turning rancid even before it finished curing.

Rancidity (and consequent DOS) is caused by oxidation of fatty acids present in oils. Factors that may accelerate oxidation include heat, light or water exposure, and contact with certain metallic contaminants (even from the humidity present in the air). Citric acid, as a chelator, provides protection against the latter. This is why it’s important to use distilled/deionized water, cleaner from metallic substances than tap water.

Along using distilled water, it’s a very good practice, or common sense rule, to use fresh oils only for soap making and natural products. It’s also true I have used oils a little over “best by” dates, and didn’t have an issue with the soap, while fresh oils turned my soap a bit rancid. Could it be contaminants, humidity present in the air? Not really sure why this happened, but it doesn’t hurt to use now citric acid to prevent rancidity in your soap, and since I have hard water, it will also improve my soap performance.

Why Use Citric Acid In This Specific Recipe

Well, because in this post, the soap made with sweet almond oil showed small signs of rancidity with time. I thought it would be a great idea to test the effectiveness of citric acid in preventing rancidity with an oil more prone to it, according to my experience. Let’s see how to goes 🙂

Citric Acid Doesn’t Reduce Soap pH: Nothing Does

Just as a side note, citric acid is an ingredient very mentioned in soap making as a way to reduce soap pH in soap bars, pretty much like apple cider vinegar. This is false, as soap pH is naturally over 8, and you simply can’t change it. You want to make a washing product with pH below 7, you don’t make soap, you make a syndet bar.

Sweet Almond Oil Soap Recipe Ingredients

As usual, besides the main ingredients of this soap recipe, I use this section to name the remaining ingredients as well as what you can change/skip in the recipe.

The sweet almond oil, lye and water are basic to make the soap. Citric acid, as it was explained, is a very good addictive to improve your soap properties, but it’s not mandatory. Use it only if you experience rancidity over time, or you have hard water in your location.

The grapefruit seeds extract is an antioxidant, an ingredient I never skip in my soaps. I’d consider it as a mandatory ingredient, but you can use rosemary oleorresin extract or even vitamin E oil as replacements (you can use similar quantities).

The natural colorant is paprika, and is also an optional ingredient, as well as the essential oil blend. As usual, for a orange-yellow soap, I use citrusy scents. The essential oil rich blend I’ve used in this recipe was created to use several essential oils I’ve already had, but you can stick only to May Chang, or add other citrus essential oils. May Chang is the one that is going to last longer.

Is This Soap Recipe Cheap?

In my area (Portugal), you can buy sweet almond oil at around 10€/lt. This is comparable to a 100% coconut oil soap, and it is still affordable. But it can’t beat extra virgin olive oil, available here at 4€/lt. Therefore, it greatly depends on how much you can purchase your oil locally, since this is the main ingredient that is going to condition your soap price.

Essencial oils make up for about half of the soap price – and it’s only 3% of the soap ingredients. Making an unscented soap can greatly reduce your soap costs. Its natural scent is usually pleasant even if very faint.
