According to industry standard methods, Chlorine (in its various forms) is one of the most commonly used bleaching agents in order to bleach the Cellulose Fluff Pulp, Cotton, Rayon or other absorbent core materials utilized in conventional feminine hygiene products.

The purpose of bleaching is to remove residues, to disinfect materials from germs and to whiten their colour.Specifically, the bleaching process involves the removal of natural and adventitious impurities in and on the cotton fibre ("scouring"), followed by the removal of its natural colour ("bleaching" in the strict sense). During this process however, it’s possible to change some of the fundamental fibre properties such as pH, biodegradability, softness, surface friction and absorbency.

Unfortunately though, Chlorine bleaching releases certain quantities of toxins, in the shape of Dioxins (chemical residues of Chlorine), into the environment, and its usage in the feminine hygiene production can leave detectable residuals in the end-product (they stay within the fluffs of Cellulose Pulp, Cotton or Rayon).The production of Dioxins in the manufacture of paper pulp products, such as tampons and sanitary pads, is not only harmful to the environment, but also unnecessarily exposes women to low levels of Dioxins every time they use these products. Dioxin settles in the fat cells of human and animal bodies and stays there for the rest of their lives, building up cumulatively over time from birth: so increased exposure means increased risk. Dioxin is a toxic carcinogenic (it causes cancer) product that could originate serious health problems, depending on the level (quantity over time-period) of exposure:

1. short-term exposure: poisoning, skin lesions, liver damage;
2. long-term exposure: damage to the reproductive system (endometriosis, abnormal shedding of the uterus lining), impairment of immune system;
3. chronic exposure: links to cancer.

There are different types of Chlorine bleaches used today in the paper and feminine hygiene industry:

- Elemental Chlorine (also called "Chlorine Gas") bleach, which is the main cause of Dioxin pollution (however, since the early 1990s, this substance has not been used as a bleaching agent in the manufacture of these products in Europe and North America);
- Elemental Chlorine-Free (ECF) bleach, which, compared to Chlorine Gas, drastically reduces the release of Dioxins: therefore, and due to its relative cheapness, the ECF one is at the present time the most commonly used bleaching method; despite its name though, this bleach is not free of Chlorine at all, but just free of Elemental Chlorine;


The only completely-free-of-Chlorine bleaching method used nowadays in the feminine hygiene industry provides for the usage of Hydrogen-Peroxide: it is referred to as Totally Chlorine-Free (TCF) method, or simply "Oxygenation".Hydrogen-Peroxide is a much safer chemical substance that can be used instead of Chlorine in order to disinfect Fluff Pulp, Cotton or Rayon from germs and whiten their colours.It is a more expensive and time-consuming bleaching process, but it is the best and healthiest available alternative to Chlorine. It does not leave any chemical substances or residue behind in the Cellulose Fluff, Cotton or Rayon and it is not harmful to human health.

Thus, notwithstanding the higher expense and time-consumption it requires, Oxygenation is today the only 100% eco-compatible bleaching method available, and therefore the only one consistent with Corman’s mission to deliver goods of the healthiest level achievable. As a logical consequence of that, Oxygenation is the only bleaching method Corman uses in the manufacture of its range of products.
