Shampoo's & Shower gels?

Why is it, that no matter what colour the shampoo/shower gel is (Pink/Green/Blue)


When it lathers its always white?Shampoo's %26amp; Shower gels?
Let us see how soap lathers.What makes Soap Lather?


Soap molecules are long chains of atoms that have two main parts:





A polar ';head'; that is attracted to water molecules and repelled by oil, and a hydrocarbon tail that is repelled by water and attracted to oil.





The hydrophobic (';water fearing';) tails of the soap molecules naturally try to get out of a watery solution and collect at any available surface. When that surface is air, the soap molecules arrange themselves in an orderly layer, with the hydrophilic (';water loving';) heads in the water and their oil loving tails in the air. Shaking a soap and water solution introduces pockets of air that, when big enough, appear as bubbles. A thin film of soap molecules coats each pocket, creating a bubble. When the shaking stops, the bubbles float to the surface. More soap and more stirring allow the formation of smaller bubbles. Foam or lather is just a conglomerate of these tiny soap bubbles. Although many people associate lather with the cleaning properties of soap, it is actually an incidental property resulting from the way the soap molecules are drawn to dirt and oil.





Since neither the polar ';head'; that is attracted to water molecules and repelled by oil, and the hydrocarbon tail that is repelled by water and attracted to oil.are coloured, the lather is white.The chemicals added for colouring the soap do not play any active part in the lathering processShampoo's %26amp; Shower gels?
I really can see no reason why it does that..it MAKES NO SENSE!!!
haha good question..........let me know when you figure it out!!
WHAT YOU CALL 'LATHER' IS BUBBLES!
my guess is because the bubbles that the foam is made out of are made of such a thin layer of the gel that the light goes through it and doesn't register the color with your eyes. Not sure about that, but thats my guess
i have always wondered the sammmmmmeeeee exact thing...ps sorry i didnt help it
