If, like me, the choice of ingredients is one of your concerns when it comes to choosing a natural, healthy and effective product, recognizing the right choice of surfactant or foaming agent (surfactant) makes a bigger difference than one might think in the quality of the latter and especially its results. This week, as my parents would say, a little dive into the why and how !
What is a surfactant ?
In short, a surfactant will produce this foam, sometimes abundant, sometimes a little less, which plays two roles at the same time ! First, the foam triggers in our mind the sensation of effectiveness of a product, deuzio, it is this foam that frees the skin from dirt, the accumulation of products as well as pollutants to which the skin is exposed. daily. Concretely, the job of the surfactant is to break the interface between water and oils and / or dirt. The surfactant therefore keeps the dirt in suspension to allow its removal by rinsing. So this is the basic concept of a soap, that is, a hydrophobic part and a hydrophilic part.
Coconut-based ingredient, Sodium C14-16 Olefin Sulfonate, used among others in our 3-in-1 liquid soap with local summer honey and provitamin B5 from J'habite chez mon chat, is known to produce an abundant foam in addition to be known to be milder and less harmful than Sodium Lauryl Sulfate. It would not represent any problems for the environment in addition to being biodegradable.
And what about the skin ?
Sodium C14-16 Olefin Sulfonate not only works well, but being derived from coconut, it comes without the negative effects associated with petroleum products and sulfates. Also, in addition to being a biodegradable compound, it would be known not to overdry the skin so as not to harm the production of natural oils allowing the skin to maintain good hydration and protection.
Sulfonate, is it a sulfate ?
The answer is no ! A few letters that make all the difference like according to Sabrina Parkins from Naturally Curly1, in a sulfonate, sulfur is linked directly to a carbon atom while in a sulfate, it is directly linked to the carbon chain via an oxygen atom. They have similar qualities in terms of the propensity to be possibly irritating to the skin, but Sodium C14-16 Olefin Sulfonate is not a sulfate.
So now, to the foam, in peace !
