Résumé : |
It is time to take another hard look at the use of chelating agents, used in a wide range of wash-off personal care products, as claims of biodegradability and environmental responsibility in many personal care products stil) currently fall short of what could simply and cost-effectively be achieved.
Chelants perform a multitude of vital tasks in personal care formulations; helping products to remain stable, preventing unwanted side-effects and increasing the effectiveness of biocides, even reducing the quantities required. And crucially they play an important role in making wash-off products - which will eventually leave deposits in our eco-system, causing potential long-term damage - that much safer. It is an opportunity to give consumers better products and the environment a better chance. So it is all good then?
Well there is a twist. The question is why are so many formulators reluctant to switch from old-technology chelates such as EDTA [ethylenediaminetetraacetic acid] and other such materials with their frankly inadequate environmental performance, when an effective alternative with proven environmental credentials currently exists and is now widely available. |
