New Tool for Liquid Soapmaking: Foamer Pumps

by Andrea on December 12, 2010

Foamer pumps for liquid soapThis summer I bought some bottles and foamer pumps for liquid soap  from SKS Bottles.

I added organic Castile soap, organic aloe vera gel, organic jojoba and some essential oils to the container, and to my complete delight, I had foam soap!

I know these containers are not new, but this is the first time I have used them. SKS says, “The white plastic foamer pumps create foam without the use of gas propellants and allow for precise mixing of liquid and air, producing a dose of high quality foam with each stroke.” Just air? Now that is remarkable!

I am now making soap, shower gel, and shaving cream. The recipes below can be adjusted based on personal preference. All the recipes use the same three ingredients in slightly different proportions. When I first made these products, I measured the ingredients. Now I just estimate!

Each of these can be made in a 50 ml foam soap bottle. Only fill your bottle 3/4 of the way, as the foam top needs room to expand.

SKS only sells in bulk. If you want to buy them individually, Aromatics International has them.

Foam Soap

  • 1 oz (30 ml) Castile soap
  • .25 oz (7.5 ml) aloe vera gel
  • .25 oz (7.5 ml) jojoba
  • 20 drops of essential oil (I like Peppermint — Mentha piperita)

Foam Shower Gel

  • 1 oz (30 ml) Castile soap
  • .25 oz (7.5 ml) aloe vera gel
  • .50 oz (15 ml) jojoba (or a bit less, so you don’t fill the bottle too high)
  • 20 drops of essential oil (I like Rosemary — Rosmarinus officinalis ct. camphor)

Foam Shaving Cream

  • 1 oz (30 ml) Castile soap
  • .50 oz (15 ml) aloe vera gel (or a bit less, so you don’t fill the bottle too high)
  • .25 oz (7.5 ml) jojoba
  • 20 drops of essential oil (I like Black Spruce — Picea mariana)

Now you have a few great recipes to work with, but I want to note that the number of drops of essential oil you add to your foam soap is really personal preference. I have added as little as 2 to 3 drops per oz (30 ml) and as much as 15 drops per oz. Some people prefer to use water in their soap too, even making blends that are 2/3 water and 1/3 castile soap! If you’d like to use water, the amount you use is all up to you.

Since there’s no preservative in this soap, I recommend making it fresh every few weeks.

I used aloe vera gel, but it was too viscous. Will aloe vera juice work instead? Or should trade out the aloe vera for tea tree essential oil instead maybe? I would appreciation any suggestions.
Thanks so much. I love your blog and recipes.

Hi Jacki – glad you are enjoying the blog! Aloe vera gel isn’t an essential oil, so you wouldn’t want to substitute it with tea tree EO. I would suggest using less aloe vera gel or just leaving it out altogether. Hope this helps!

How come you don’t add water to the recipe? All the recipes I see online says to use like 2-3tsp of Castile soap to 8oz of water and out it in a foam pump. Castile soap is so concentrated and expensive to use. A little hoes a long ways.


Andrea Butje May 3, 2014 at 9:21 am

Hi Anna,
Thanks for your question. You can add water for sure- I just like using the full concentration of castile soap and always have done it this way. I is personal preference I think- no real rules here. 🙂

I have loved these recipes! Recently, however, I got a different kind of castile soap, which had a gel-like quality. I’m finding that this starts to clog up the pump mechanism – seems the gel starts to harden a little. Have you run into this? I may need to go with a more liquid castile soap like the original castile from Aromatics International?

Andrea, YAY! I can’t wait to try this out. I would like to order the foamers and would like to know if you ordered a specific bottle to go with it? Beth

Hi Andrea
Thanks for the message on facebook about buying with the bottles…I am unable to connect to facebook for some reason (Mercury retrograde I hope…not something more sinister or difficult!)so wanted to say thanks here…I have an aversion to the clear bottle, but I will try to overcome it so I can experience this foamy wonder! 🙂
Best holiday wishes to you,

Hi Andrea, So nice to stay in contact through your blogs, etc. Long time no see. Things are good here at the lavender farm. Great harvest this year. YEA! Have you tried making this soap formula in larger quanities? I know my customers would love this and I would like to try making it as well. Does the formula stay stabilized at say, a gal, or 5 gal mixtures? Thanks Elizabeth

Hey Elizabeth!
I have not tried to make these formulas in large quantities, but if you do, please report back and let me know how it works! Great idea for your customers with your beautiful lavender!

What a fascinating concept. Must try!


Christina December 13, 2010 at 8:16 am

Love these bottles!!!
I made Christmas soap blends for my clients this year, Balsam Fir and Mandarin, YUMMY!

Hi Andrea~

Perfect timing! I just tried a hand soap recipe last weekend in these little foamers. My jojoba ratio was too high, which meant no nice foam puffs. Thank you for the proportions, looking forward to round 2. :o)


Rebecca Silence December 12, 2010 at 7:32 pm

I use and love these SKS foamers, too! Those velvety puffs of luscious foamy soap are to die for!

Thanks for sharing the specific proportions of ingredients… Have you found that the aloe gel settles out on the bottom at all?



Jaime December 12, 2010 at 6:30 pm

I love these! Just refilled mine this morning. Thanks so much for posting the recipes!


Claudia Chapin December 12, 2010 at 5:20 pm

I use the SKS foaming pumps, too, and they produce such a nice, creamy foam.


Helene October 17, 2011 at 10:09 pm

I looked on the SKS website. They only sell the bottles in bulk. Do you know where to get them individually?


Andrea Butje October 18, 2011 at 7:25 am

Hi Helene,
Yes, you can buy them individually at Aromatics International.
