Nothing to swap. I've never not considered the planet when it comes to washing.

PLanet Ark powder is actually a bumsteer. Most liquids, like Amolin Sensitive, are actually better for the environment because they have lower sodium levels.

Check out Lanfax Laboratories for the lowdown.
Well, I thought I was using a good choice and had no reason to swap but I use Aware Sensitive powder! Thanks for the link- I can't find Amolin on there so not sure how you made the comparison but Earth Choice is a better choice so we'll get that next time. I've also used up a sample of soap nuts and I'minspired again to buy a bulk lot of it so I can use those again.
