Sodium Lauryl Sulfate (SLS) vs Sodium Lauryl Sulfoacetate (SLSA)
We have made our NEW bubble bar slices with a wonderful Naturally derived surfactant – Sodium Lauryl Sulfoacetate (SLSA).
I can almost hear the inward gasps of shock and horror from here. “Did you say SLS?”
No - we are NOT using the highly irritant Sodium Lauryl Sulfate (SLS) but the infinitely more milder and gentler on the skin Sodium Lauryl Sulfoacetate. (SLSA)
SLS is harsh on the skin and is highly irritant
Whereas SLS -Sodium Lauryl Sulfate is cheap to use and produces a large number of bubbles… it is very harsh on the skin because it is made up of a relatively small molecule and so penetrates the skin barrier easily causing irritation and sensitisation to many.
SLSA is extremely mild – perfect for sensitive skin
Sodium Lauryl Sulfoacetate (SLSA) on the other hand is derived from coconut and palm oils.
It is listed as being able to be used in ‘organic’ certified products and is much milder than most other surfactants. This is why it can be used in the most sensitive skin formulations where bubbles are required.
The reason for the mildness of this wonderful ingredient is that a Sodium Lauryl Sulfoacete molecule is so large that it cannot penetrate the skin… and so greatly reduces its ability to irritate it!
In fact you can even use our bubble bath products formulated with SLSA on adults, children and babnies with psoriasis, eczema and dermatitis.
So we are very pleased to be able to use Sodium Lauryl Sulfoacetate as our primary bubble maker in our products.
