In 1879 Dr. Joseph, Lawrence found a safe
antiseptic. He named it Listerine after Dr.

to Jordan Wheat Lambert, who made a lot of profit
from it.

  rubbing alcohol

• It is poisonous if taken in by the body through
  the mouth

Properties of Plastic

• Plastic is a polymer and it can be in any color.
• Plastic is made up of plasticizers, fillers,
  pigments, and other addictives
• Plastic is durable, hard, has a good elasticity,
  and is resistant to heat, cold, and acid.
• There are two basic types of plastic
  thermosetting and thermoplastic
• Thermosetting cannot be remolded after it is used
  
• Thermoplastic can be remolded after it has been
  used

How Listerine Is Made

• To mix all the ingredients, flow meters
  turn on valves at each tank and measure out the
  right proportion, according to the Cool Mint
  formula developed by WL RD in 1990. This
  blending process is constant as ingredients are
  added to the several-thousand gallon vat, the
  properly blended liquid is continuously
  transferred to a separate holding tank. Next the
  Listerine flows through a pope to fillers along
  the packaging line. The fillets dispense the
  product into bottles delivered continuously from
  a nearby plastics company for just-in-time
  manufacturing.
• The bottles are capped, labeled and
  fitted with tamper-resistant safety bands, then
  placed in cardboard shipping boxes known as
  shippers that holder a dozen 500-milliliter
  bottles. During this process, machines
  automatically check for skewed labels, missing
  safety bands and other problems. The entire
  production cycle, from the delivery via pipe of
  the Listerine liquid to the point where bottles
  are boxed and ready to go, takes a matter of
  minutes. The line can produce about 300 bottles
  per minute. Which is a lot more than the 80 to
  100 bottles that the line produced per minute
  before 1994.

Sugarcane
A raw material in Listerine is sugar . Sugar is
grown in fields of sugarcane . Sugarcane is
grown in places where the temperature is 70 to 90
degrees and very humid .

How Listerin Affects the Enviroment
The only way Listerine affects the environment
is that the bottle can be recycled.
10
History of Listerine
The way Listerine has changed is that is the
bottle has been changed from glass to plastic .
The reason is because it is lighter, it wont
shatter if dropped, and able to be recycled. I
dont think Listerine will change in 10 because
they have Listerine Pocketpaks . years because it
is a very good product and it is used by many
Americans.. I dont think it will get any smaller
