If a shake the shampoo bottle until its content foams up inside the package and… then I use this shampoo… will it make less foam when I am shampooing?
I’m not sure I understand. Shampoo is really thick and won’t shake well. It won’t generate a lot of foam until its diluted with water.
I will reformulate my question… If a make a foam with some product (in general) and wait until it de-foam… next time I try to do the foam again (with the same product), it will foam up like the first foam? Or it will loose its ability to make another foam, since another foam was already previously done?
I even do not know why I want to know that LOL, but I am curious to know…I see…I think.
Foam is a function of how the surfactant molecules interact at the water-air interface. The surfactants (the “foamers” in the product) lower the surface tension of the water enough that it can sort of stretch out and hold pockets of air (aka soap bubbles.) That’s a over-simplified explanation but you get the idea.This only happens to a large extent when you dilute your shampoo or body wash or whatever in water. You don’t get a lot of foaming just in the bottle because there’s not enough water (typically.) So if you shake up your shampoo bottle until it foams a little, the product will STILL foam when you use it.I’m not sure if my explanation was totally clear but I hope that helps.
