Soapmaking Benefits of Egg Yolk Soap

In cold process soap, egg yolks also help to create a rich, thick lather.

Making egg yolk soap is easy and fun if you follow a few simple (and easy!) soap making tips.

I love using egg yolks in soap as they make the lather of your soap feel extra rich, creamy and luxurious. Basically another soapmaking fat, the properties of  the egg yolks give egg yolk soap a rich, thick lather. Therefore they make a lovely ingredient in any cold process soap recipe in which you want to beef up the lather. (It’s extra dreamy in low cleansing soap bars, too.)

Cold Process Egg Soap Recipe (with Egg Yolks)

© Rebecca D. Dillon


3.92 oz. palm kernel flakes
3.6 oz. 76° melt point coconut oil
9 oz. sustainable palm oil
10.8 oz. pomace olive oil
4 oz. safflower oil
1.08 oz. castor oil
3.6 oz. rice bran oil

11.5 fluid oz. distilled water
4.9 oz. lye/sodium hydroxide

2 egg yolks
1 Tablespoon white kaolin (cosmetic) clay
2.25 oz. fragrance oil of choice, optional

Egg Yolk Soap Notes:

Water as % of oils=32%
Superfat/Discount 6%

This homemade cold process egg soap recipe will yield 10-12 bars of soap approximately 4 oz. each depending on how they are cut and fits inside my DIY wooden loaf soap mold.

There is zero egg smell to this cold process egg soap recipe once it has cured. I noticed a slight smell when I first cut my homemade egg yolk soap into bars, however it had completely dissipated by the next day and smelled only like the fragrance oil I’d used for my own batch.


To make this homemade cold process egg soap recipe, you’ll need to follow your basic cold process soapmaking method instructions. (If you’ve never made cold process soap before here’s a good, inexpensive beginner’s cold process soap recipe you can try.) Be sure to take all proper safety precautions when working with lye including goggles and gloves.

You’ll need to begin with eggs that are room temperature so I suggest removing your eggs from the refrigerator ahead of starting the soapmaking process. Crack the eggs open and separate the whites and yolk from two eggs. You’ll only be using the yolks for this egg yolk soap recipe so feel free to scramble up the whites in an omelet! Alternately you could simply use one egg in its entirety – both the white and yolk – for a somewhat different result. While egg yolks serve as a fat in a cold process egg soap recipe, the protein in egg whites are believed to have an astringent effect on skin.

Once your eggs have reached room temperature, you are ready to begin the soapmaking process.

Begin the soapmaking process for this egg soap recipe by first measuring out the distilled water in fluid ounces. (Alternately you can use rosewater in place of the distilled water if you’re after a face specific soap.) Pour into a heat safe pitcher. Next, using a digital scale weigh out the lye. Slowly pour the lye into the water in a well ventilated area and stir until all the lye has dissolved. Set aside to cool.

Now weigh out the palm kernel flakes, coconut oil, palm oil, olive oil, safflower oil, castor oil and rice bran oil using a digital scale and combine in a stainless steel pot. Heat until all of the oils have melted, then remove from heat and set aside.

Next weigh out your fragrance oil, if you’re choosing to scent your egg soap, and set aside. (You can also use essential oils in lieu of a fragrance oil, but you’ll want to use half the amount.)

Now measure out the kaolin clay and set aside.

Once the lye-water and soapmaking oils have cooled to around 90°F you’re ready to make this egg soap recipe.

You’ll need to begin by tempering your egg yolks. To do this remove about a cup of oil from your cooled soapmaking oils into a cup or bowl. Add the egg yolks and mix well with a whisk, fork or even a stick blender. Set aside.

Now slowly pour the lye-water into the soapmaking oils. Mix with a stick blender until you reach a light trace, then add the clay, fragrance, and egg-oil mixture. Mix again until the soap starts to thicken again and all ingredients are fully blended into the soap, then pour the soap into your prepared mold.

Lightly cover the soap with cardboard but don’t insulate the soap loaf.

This homemade cold process egg soap recipe is made with egg yolks. Eggs have long offered skin care benefits that include tightening skin, shrinking pores, and calming redness and breakouts. In cold process soap they also help to create a rich, thick lather.

After 24 hours you can unmold your egg yolk soap loaf and cut it into bars. Allow your egg yolk soaps to cure 4-6 weeks before use, then wrap and label as desired.

  1. love this recipe looking forward to tying it!

  2. Good morning. Could you tell us if you are have a Pinterest site ? I so love your recipes. Thank you so much.

  3. Will this cut down the shelf life? I have to try it!

  4. Thank you for sharing your egg soap. I recently did a ‘secret feather’ egg soap and it turned out great!

  5. Hi Rebecca,
    I too use eggs in my soap recipes and love the final product. It’s that something wonderful that makes your soaps more conditioning. The thing is knowing how and when to add the eggs. They must be tempered before adding. I use milks as well so I temper them into my milks and add to my oils at RT before pouring my concentrated lye solution. Did you know that you got it going on? 😉

  6. Hi Rebecca! Would this be good for face or you don’t recommend it? Do you have a recipe for facial soap bar for dry skin?

  7. am a beginer in soapmaking i was happy to com across ur site n i wld be glad if u can teach me how to make soap because i intend to be doing a commercial soap supply thanks from prince

  8. Hello Rebecca!

    Just curious, why bother using coconut oil if egg yolks help create a rich, thick, lather? I plan on making soap using only olive oil as the base. I’ve been researching additives that will help increase lather and hardness (I really don’t want to use coconut or palm oil) and that’s how I came across your recipe. I’m still doing more research, but after reading your recipe, incorporating egg yolk to help increase the lather seems like a pretty good alternative–also sugar! Supposedly 1 tsp per lb of oil will help create a light, bubbly lather with large bubbles 🙂

    Anyway, my question to you: How do you determine how much egg yolk to use? Is there a calculation? Like X oz (egg yolk) per lb of oil? Someone said they subtract the egg yolk weight from whatever liquid they use for making the lye solution… Which is obviously not what you did–I added your oils together and you used one egg yolk per 18 oz of oil.

    Also, I was reading a thread elsewhere and someone said they simply blend the egg yolk with all the oils prior to adding their lye solution. You said to set about a cup of oil aside, blend the egg yolk into that, then add it along with the additives after the lye solution/oils reach a light trace. Why not just do the aforementioned?


    (Sorry if anything came across as “snide”! I’m a newbie to soap making and am genuinely curious 🙂

    • You’ll want to use a soap calc to figure out what properties your soap will have as far as lather. I have heard that corn oil is an inexpensive substitute for coconut oil – a soaper on the market uses corn oil for this purpose in many of her soaps – and helps to create a great lather. Sugar and/or egg alone likely aren’t going to do the trick when compared to soaps make with coconut oil or palm kernel oil. You could try these though in a basic Castile soap recipe – 100% olive oil – and experiment from there. My tutorial on creating cold process soap recipes using a lye calculator can help you see how cleansing your final bars would be based on the oils you are using and is a great starting point.
