ChemSec Director Anne-Sofie Andersson has recently published an article discussing the tendency for Chemical companies to research and develop sustainable alternatives to their harmful chemical products, and why these sustainable alternatives often don't see the light of day.
Often, these alternatives are kept 'for a rainy day', so that when a particular chemical is banned or restricted by legislation, or when at least 40% of customers start asking for an alternative, they are already ahead of their competition.
