I also never worried about light sensitive but then came across to this article. even the bottle I have of triton X is not transparent thats why posted this que.
I too doubt that triton x-100 is light sensitive, but I couldn't find any relevant article. While surfing the net, I came across your post and tried to open Roche's link that you had provided above. But, I think the link is now not valid. Could you help me in getting the fresh link? It would be really great if you could provide me your findings on its light sensitivity or any such related article.
