How to Make Bubble Bar Without SLSA (DIY Recipe)

Do you want to know the exact recipe for making bubble bars without SLSA? If YES, here is a 6-step guide on how to make a bubble bar with SLSA.

Sodium lauryl sulfoacetate, also known as SLSA, comes in many different particle types: Powder, coarse and flake. The most popular form of the Sodium lauryl sulfoacetate is powder. The next is SLSA coarse, and then the flake. The coarse and the powder are often used in bath bombs and bubble bars and other similar foaming bubbly products.

Like SCI, the SLSA produces very high quality long-lasting foam. Powder SLSA is a very fine particle and although it is easy to use, can get you to sneeze while you use it.

Many users substitute the coarse to reduce the irritation of the very fine particles of the powder. SLSA’s molecular size of the surfactant is large, and therefore it does not penetrate the skin. It is derived from coconut and palm oils and is a safe, skin-friendly cleanser that provides rich quality lather.

Sodium Lauryl Sulfoacetate is not referred to as SLS in the beauty industry and has a completely different profile in terms of performance and mildness. This mild plant-derived surfactant creates a lather that effectively removes surface oil, dirt, and bacteria, without stripping or drying sensitive skin.

SLSA is also hydrophilic; this means it is attracted to water, which enables it to dissolve more readily in water, thus providing superior rinse ability. It is becoming the standard foaming ingredient for those who are looking for “natural” products for body and hair care.

Recipe You Need to Make Bubble Bar Without SLSA

Most bubble bar recipes in the market currently is made from SLSA or sodium lauryl sulfoacetate, which is much safer for your skin than sodium lauryl sulphate. Howbeit, both are chemicals that can irritate your skin to some degree, and SLSA is a very fine powder.

Also, note that you will need to wear a mask when using it or it can get into your nose and sinuses. Due to these issues, here is a safer recipe that doesn’t contain SLSA. This Bubble Bar recipe contains simple nourishing ingredients that will make your bath bubbly, and will also leave your skin soft and silky.


  • ¼ cup non-GMO cornstarch or arrowroot powder
  • ¼ cup citric acid (find it here)
  • 1 cup baking soda
  • ¼ cup milk powder
  • ¼ cup cocoa butter or Shea butter, melted (find cocoa butter here and Shea butter here)
  • 2 Tablespoons liquid oil such as sweet almond, avocado, or fractionated coconut oil
  • 1 Tablespoon natural liquid soap (use your favourite brand or learn to make your own liquid soap)
  • A few drops of food colour or a skin safe soap colourant
  • 8-10 drops essential oil (find pure essential oils here)

The 7-Step Process Involved in Making Bubble Bar

  1. Start by sifting all of your dry ingredients together to be sure there are no lumps. Add the melted butter and oil and stir well. You may also want to put gloves on to really mix it well. Add the soap in a little at a time, mixing well after each addition.
  2. Drip the colour and mix well, or divide the mixture into two or three bowls and colour each one separately. At this point, add the essential oil and mix it in. You should have a dough-like mixture. If it is too dry, add a bit more liquid soap. You can also add a bit more cornstarch or arrowroot powder if it is too wet.
  3. Turn out onto a powdered surface and knead like bread dough. When it gets firm, you’re ready for the next step.
  4. Carefully shape the bars any way you like. You can layer colours, roll them into a log, and cut them to the desired size. It can also be shaped into balls. Try adding bits of each colour to the balls as you are shaping them for a fun effect.
  5. Then let your bubble bar dry out for 2-3 days. Once they are thoroughly dry, place them in a jar with a tight-fitting lid. These will keep for a few months unless you use them up before then.
  6. To create fun shapes, make and pack the mixture into an ice cream scoop. Mix colours to create a swirled ice cream effect. Next, press the lever and gently place the scoop onto a sheet of parchment paper. This works best with an ice cream scoop with a trigger. This will give you ridges that look like real ice cream.
  7. Finally, dust with glitter if you like. There are several colours of biodegradable glitter that can be used.


Sodium Lauryl Sulfoacetate, often called SLSa, is a top performing, sulphate free gentle powder surfactant, derived from sustainable feedstocks. It conforms to Ecocert natural and organic cosmetic standard.

Sodium lauryl sulfoacetate is used to make foam in bath products like dry bubble baths, bath salts, fizzy bath bombs, dry bath bubble and any other formulation where you want a nice foamy soap that is mild and phosphate free and non-toxic.
