About Ingredients


We want you to have every confidence in our products, their natural origin, their authenticity and their provenance. Just like we sell our soaps “naked” we want to show you that we have nothing to hide when it comes to ingredients.


That’s why you will find listed here every single ingredient that is contained in either some or all of our Pure French Soaps. Made with natural ingredients and free from additives and nasty chemicals, our soaps should be perfect for even the most sensitive skin, but first a word of caution.


It should be remembered that even the most natural organic ingredients can be a source of reaction for certain individuals, or for those who suffer from allergies or skin problems (think poison ivy or peanuts for example). If you have, or suspect you have sensitive skin or if you have any concerns we would recommend you carry out a patch test. Lastly, if you know that you have an allergy to certain ingredients, then you can search for them here.

If you can’t find them great!

Savon de Marseille French Soap Ingredient:


Tetrasodium Editronate


What is it used for?

Chelating, emulsifying and stabilising agent

Tetrasodium Editronate


Chelating agent and stabiliser


Tetrasodium Editronate (which stands for ethylene diamine tetra acetic acid) is one of the salts of editronic acid. It is a water-soluble compound added to oils and alkali to aid successful saponification. Its main function is as a chelating agent (which means that it binds to certain mineral ions to inactivate them). Through this action, it can prevent the deterioration of cosmetic and personal care products, as it stops the growth of microorganisms. It helps stabilise formulas by acting as an antioxidant and therefore prevents changes in colour, texture and fragrance. Tetrasodium EDTA also helps maintain clarity, protect fragrance compounds, and prevent spoiling. One of its main uses it to help personal care products work better in hard water.

The following products contain:
