What is Benzene and is it harmful to humans?
Antimony trioxide (ATO) is a compound of antimony
that is used in small amounts as a catalyst for the manufacture of
PET. Antimony trioxide occurs naturally or can be prepared
synthetically from antimony ores. Antimony compounds are
widely used in paint pigments, ceramics, glass, rubber, plastics and
even medicines. Antimony is chemically bound into the PET
polymer. In normal use of PET there is no leaching of antimony
into the beverage. If antimony is ingested it is believed to
not be carcinogenic but is if inhaled into the lungs.
PET has been used for food and beverage containers
for nearly 30 years without any known incidences of causing adverse
effects, and is approved as safe for contact with foodstuffs and
drinks by the FDA. Extensive testing of PET and PET packaging
has repeatedly shown it to be of very low toxicity. The
amounts of antimony found in PET-bottled water are insignificant and
do not pose any health concern.
Acetaldehyde (AA) is a degradation byproduct
formed when PET is melted and is believed to affect the taste of the
product. There are two ways a PET bottle can have AA, one
being that if the resin is not processed properly then AA will be
found in the resin. This was more of an issue in the early
days of PET but is not so much an issue now due to the demand of the
water bottling companies demanding low AA levels.
AA is more of a problem with the blow and fill
manufactures because AA is typically dissipated from the bottle
within 72 from the blowing process. The manufactures must
watch the molding process to make sure they do not over dwelling or
overturning the material in the screw which both creates AA (overprocessing
the PET resin).

Bisphenol A, commonly abbreviated as BPA, is an
organic compound with two
functional groups. It is a difunctional building block of
plastics and plastic additives. It is an important
monomer in the production of
Suspected of being hazardous to humans since the
1930s, concerns about the use of bisphenol A in consumer products
were regularly reported in the news media in 2008 after several
governments issued reports questioning its safety, and some
retailers removed products made of it from their shelves.
It is a common misunderstanding that BPA is found
in PET bottles. BPA is not used in the production of PET (#1)
plastic and is also not found in ENSO bottles.

Phthalates (pronounced “thal-ates”) comprise a
large family of chemicals characterized by a benzene ring structure
linked to two side chains. Generally, the term phthalate is
used to identify the ortho chemical configuration, where side chains
arise from adjacent carbon atoms of the benzene ring.
Phthalate esters are the most common group of
chemicals used as plasticisers (plastic softeners) worldwide, most
frequently for polyvinyl chloride (PVC) plastics. Plastics
containing phthalates are used in industrial and consumer
applications such as electrical cable insulation, flooring, carpet
backing, automotive parts, footwear, children’s toys and exercise
Phthalates of this kind are not used in the
creation of PET #1 plastic bottle. Terephthalate is used as a
plasticizer and has no known health risks.
No. All of the organic compounds contained in the
ENSO additive are considered as safe plastic bottles for food
contact and have no known adverse health effects. The
compounds are also not found on the toxic and potentially harmful
substance list of CA Prop 65. This State of California
legislation identifies certain toxic and potentially harmful
substances and provides limitations for their use. No products used
in the ENSO additive are listed in Prop 65.
There are no known health risks with placing ENSO
or #1 PET bottle in the microwave. However, plastic bottles are
typically very thin and can pose serious burn risks if the product
contained in the bottle becomes hot. It is also not
recommended since there are no known reasons why it would be
necessary to heat up such a bottle in the microwave.
No. There are no differences in physical
properties with ENSO bottle as compared with traditional PET.
Leaving a PET bottle in a hot vehicle will not leach chemicals but
will affect the flavor of the beverage. It is not recommended
for either traditional PET or ENSO bottle to be consumed if left in
a hot vehicle.
ENSO bottles with the ENSO additive are approved for hot fill
products. Extended leaching tests verify that moderate
temperature increases do not pose any leaching risks.
A bigger concern would be the affect of heat and
light to the liquid within the bottle. Spring water and other
liquids that have algae and natural organisms will begin to grow
with heat and light, beverages with sugars will also be affected by
No, Benzene will not leach into the water.
However, Benzene can break off of the polymer chain and end up in
the beverage from excessive wear of the plastic bottle.
Benzene is an
chemical compound and a known
carcinogen. It is made of carbon and hydrogen forming a
carbon ring and is commonly found in the environment. It is a
flammable liquid with a sweet smell and a relatively high
Outdoor air may contain low levels of benzene from tobacco smoke,
wood smoke, automobile service stations, the transfer of gasoline,
exhaust from motor vehicles, and industrial emissions. Benzene
can pass into air from water and soil surfaces. Once in the air,
benzene reacts with other chemicals and breaks down within a few
days. Benzene in water and soil breaks down more slowly.
Benzene in the environment does not build up in plants or animals.
When you are exposed to benzene in drink, most of
the benzene passes through the lining of your gastrointestinal tract
and enters your bloodstream. Once in the bloodstream, benzene
travels throughout your body and can be temporarily stored in the
bone marrow and fat. Benzene is converted to products, called
metabolites, in the liver and bone marrow. Some of the harmful
effects of benzene exposure are caused by these metabolites. Most of
the metabolites of benzene leave the body in the urine within 48
hours after exposure.
Excessive exposure to benzene can be harmful to
the immune system, increasing the chance for infection and perhaps
lowering the body's defense against cancer. Long-term exposure
to benzene can cause cancer of the blood-forming organs.
