Many bottles now are actually made of poly-beta-hydroxybutyrate which is biodegradable. It's made in bacteria that uses this compound to store extra carbon, so there are enzymes that degrade it, in contrast to plastic, which takes hundreds of years to degrade.
shampoo bottle is made up of bakelite plastics
The process by which bakelite plastics are made is known as polymerization
just checked one of my shampoo bottles ; HDPE is used for Tresemme bottles. (high density polyethylene)
Thermoplastic
PET (polyethylene terephthalate), this is plastic recycling type #1
Bottle caps are made not out of PET plastic because that would make the separation from the bottle imposible, PET does not float, so the caps have to be HDPE, PP or other plastic that is less dense than water, thus makin the separation process posible when the bottles are recycled.
- the polyethylene plastic bottle is unbreakable- the glass has a solubility (low and dependent on the type of glass) in acids
Plastic.. Depends what type, but plastic pipes are made from plastic. :)
Usually nylon.

It really depends on the brand of shampoo or the type of plastic that the bottle is made out of. Some companies have started making bottles out of recyclable plastic so check and make sure. If you don't know if a shampoo bottle is recyclable, check the bottom of the bottle or the label on the back for the number that is being surrounded by three arrows forming a triangle. Almost every city recycles numbers 1 and 2, but it depends on where you live. Hope this helps!
size shape (smooth sides/jagged sides) type of plastic it is made from
a high density poly ester (HDPE)....a type of plastic
plastic resin

It depends on the size, of course, and the thickness, but a small bottle contains about 20 grams of plastic.

You can buy dry-scalp shampoo, in a 250 mL bottle. It is extremely helpful!
