Sodium Lauryl Sulfoacetate (SLSa) Powder

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

Great to use in: 

  • Bath Bombs
  • Bubbly foaming bath salts,
  • cream & paste shampoos,
  • Cleansing creams,
  • Fizzy shampoo bars
  • Bubble Bars
  • and syndet bars.

Our SLSa also known as Bubble Magic (tm)  is much milder to the skin than ethoxylated alcohol sulfates such as Sodium Lauryl Sulfate and other cheaper, more irritating  surfactants. It is an excellent choice to use as a surfactant if you are looking for a replacement for Sodium lauryl Sulfate powder or other more harsh products. And, SLSa is often used to replace regular soap whenever soap sensitization is found. Minimal to no irritation will occur at a usage rate of 3% concentration typically

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. It makes a blanket of bubbles that last! Cheaper foam / bubble products are harsh, and do not last as long as SLSa, a top quality surfactant.

1 Lb of powder equals approximately 2.5 cups.

Country of Origin:  United States

    Only brand for me

    This is a fine powder form SLSA. It's of optimal consistent quality. In my formulations I find that less is more specifically this SLSA. Always wear a mask for safety.

    Fave Soaping Agent

    Posted by Jordan Wiley on Oct 9th 2019

    The 25 pounds of SLSA comes in a bag rather than a pail. Not a huge issue but it makes it somewhat clumsy to use when you only need to get a few ounces or pounds out. The powder itself is great!

    Posted by Demetrics Anderson on Jul 21st 2019

    Added this product to one of my formulas and it did exactly what I needed it to do which was stabilize foam and made it last long.
