Well I got the bottle of Aerify that was mentioned in another thread about aerifying. Says on the bottle that the ingredients are 60%-Ammonium Laureth Sulfate 40%-other ingredients The 1st is a detergent used in alot of things shampoo is one of them so 60% of this $34.00 2.05oz's is shampoo/surfactant and it can cause eye and skin irritation On the instr sheet it instructs you to add the Aerify 1st then water-on the lable it instructs to add after the water for best results and to minimize foaming. And I guess you will need to do that because your spraying on mostly shampoo. It claims to eliminate the need for machanical aeration...we will see I almost just sent it right back,but decided to try it and see what happens 1st. Why dont they just sell you the 40% "other ingredeints and let you use regular shampoo to mix with it I do not know other than the fact they couldent charge so much if it was a little amount inside.
