The powder doesn't dissolve in cold water. It really doesn't work well in warm water either. I had to use hot water to get this to really dissolve up in the wash. On top of that, if you aren't careful, you end up with powders in your clothes and sometimes in the bottom of the washer after the wash.
It has a good stain fighter and got the clothes smelling fresh and clean but it wasn't a pleasant reaction on my skin and it wasn't a great product in the wash. I had to kind of put my hand in and swish this around to get it all absorbed. The powder irritated my skin on contact.
It might be the stuff to go to for someone who hot washes everything and doesn't have sensitive skin but it wasn't the product for me in my house.
I was less than happy with this product. It doesn't dissolve well.It has a good scent and smells like the tide I love.
