What is SLSa

Also known as Lathanol, SLSa is a skin-friendly cleanser producing a thick lather. Derived from Coconut and Palm oils, the full name is Sodium Lauryl Sulfoacetate. A clean, organic and natural product growing in popularity in the cosmetic trade.

What Does SLSa Stand For in Bath Bombs?

SLSa stands for Sodium Lauryl Sulfoacetate, it is a common replacement for natural soaping agents, and is especially effective to create rich, thick bubbles in bath bombs and other cleansing products. Not to be confused with SLS, which is Sodium Lauryl Sulfate, a fraction of the price, and pretty bad for your skin.

WARNING: If you see very very cheap SLSa for sale, double check it has not been incorrectly labeled, or worse still, someone trying to make a huge profit on a far more inferior product that will likely cause issues with your skin – DO NOT USE SLS in Bath Bombs

Is SLSa Safe in Bath Bombs?

When we see a chemical name such as SLSa and we can not be sure what it is, all sorts of things might run through our heads as to whether is using SLSa in bath bombs is safe or not.

The fact is, adding SLSa to bath bombs is perfectly safe, and in fact, can very much enhance the end result of DIY products made for family, friends, relatives, and fun as well as have craft fayre customers coming back again and again after finding out just how rich the lather from your bath bombs is.

The trick now is keeping it secret so they keep coming back!

How Much SLSa in Bath Bombs?

The amount of SLSa used in bath bombs should roughly match the same level as the citric acid. Of course depending on the size of your bath and how many bath bombs with SLSa you plan to make, will also dictate how much physical product you will need.

The recipe above can be adjusted up to make bigger bathes, just remember to multiply the amounts just the same for every ingredient.

How Much do SLSa Bath Bombs cost?

They will cost no more than other bath bomb recipes you decide to make. You can buy quite small quantities of SLSa, so there is no need to be spending $100’s of dollars on products that will be used once and be no good next time you go back to use it again.

The great thing with SLSa is once you start using it, you might just get hooked with the creamy bubbles it creates and not want to go back to Cream of Tartar Bath Bombs or Cornstarch

SLSa Substitute for Bath Bombs

There are dozens of options for substitutes to SLSa in bath bombs. However, the choice is narrowed down if you are looking to create the same incredibly rich lather SLSa does.

You can replace the SLSa in the recipe above with more citric acid,, this will create the same fizziness but the lather will not be so dense of rich.

Cream of Tartar and Cornstarch are other replacements

Difference between SLS and SLSa?

There are a number of differences between SLS and SLSa that we should be aware of as bath bomb creators. The two major ones are the molecular structure, the second is the price, with SLSa being far more expensive. And with good reason.

  • Lab created (SLS) v Natural (SLSa)
  • Cheap (SLS) v Not Cheap (SLSa)

The molecular structure of lab-created SLS is that it is very small and therefore penetrates the skin quite easily increasing the risk of irritation problems.

SLSa has a far larger molecular structure and conversely is a skin-friendly natural product that is just perfect for creating a creamy rich bubble in your bath bombs.
