Imagine a sanitary napkin as a multi-layered sandwich of ultra-processed and chemical products, each layer having a specific role:
1. The top layer: This is the part in contact with the skin. Permeable, it lets the flux pass while keeping the surface dry thanks to the polypropylene that makes it mostly.
2. The absorbent core: This is where the majority of chemical agents and endocrine disruptors, cellulose, are hidden, along with its faithful acolyte, the super-absorbent polymer (SAP).
3. The distribution layer: We would not have thought of it but it was; an irrigation system in your protection, distributing the liquid over the entire surface of the towel.
4. Waterproof barrier: usually made of polyethylene.
5. The adhesive: to attach it to your underwear!
Cellulose: this discrete agent
Accounting for 40 to 60% of the total composition, cellulose is the major component of sanitary napkins. But what exactly is it?
Origin and nature
Cellulose is a polymer, mainly extracted from wood. These are tiny fibers from trees such as pine or eucalyptus. It is the same material that gives their rigidity to plants!
The shock duo: cellulose and SAP
In modern napkins, cellulose teams with super absorbent polymers (SAP)
Conclusion
The next time you use a sanitary napkin, you will know that you are holding in your hands a small sandwich of chemical composite and ultra-processed materials, whose main component, cellulose, is as common as it is fascinating. All these components are a veritable cocktail of endocrine disruptors and disrupting agents of your vaginal flora
So, impressed by the composition of sanitary napkins? Want to know more about the concerns and effects on your health?
