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 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 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 double check it has not been incorrectly labelled, 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 ofthings 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, friend, relatives and fun as well has have creaft 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 product that will be sued 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 rcipe above with more citric acid,, this will create the same fizzyness but the lather will not be so dense of rich.

Cream of Tartar and Cornstarch are other replacements

Where to Buy SLSa?

I see no reason to not buy your SLSa from Amazon. For one, you will be getting what you expect and it takes no real time to search, order pay and have it delivered, If you have Prime you may even get it tomorrow.

Because I get as many viewers from Europe now as I do from the US, I have links for both .com and Amazon sites here

For either link, you can choose the size you want, depending on your needs or how many bath bombs you intend to make

Is SLSa Vegan?

If you are lookin to create vegan Bath Bombs then you’ll be pleased to know SLSa is Began friendly, not to mention the best bubble making ingredient for bath bombs.

is SLSa Organic?

You can purchase the PURE brand of Organic SLSa from Amazon. I am a big fan of PURE products for their organic and ethical values, which extends beyond the products to the packaging too.

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, withe SLSa being far more expensive. And with good reason.

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

The molecular straucture 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.
