PVC has been a popular material used in all kinds of kiddies' products
and toys. Some of the products made from PVC or containing PVC, include:
 |
Toys used in water (bath tub or beach)
like bath ducks, Inflatable beach toys and pool balls |
 |
Some baby care items |
 |
Dolls |
In over 40 years of use in toys, there hasn't
been a single known case of a child's health being harmed due to
the use of PVC in soft toys. Yet, Greenpeace's claims that children
could be harmed by plastic toys, has caught the attention of policy
makers and the media.
The use of PVC in toys that are designed to be put into the mouth
of children under three years of age, has already been banned by
some countries, especially in Europe. The European Commission has
taken the position to ban six types of plasticizers (softeners).
The ban concerns certain components that could cause health problems
if they migrate or leak from PVC toys and does not apply to PVC
itself.
No convincing scientific documentation proving plasticizers are
dangerous to humans exists. In fact many of the other materials
used in toys, such as rubber, wood, PCV etc.contain components that
can be extracted by chewing or sucking. It is important that the
toxicity of any of the components used in the manufacture of toys
be understood before they are used and the level of exposure be
known before the suitability of the materials is assesed.
PVCs popularity in toys is because of the advantages it offers
on material, cost and safety. Both factors are very important for
toy manufacturers to produce affordable toys, especially according
to fast changing popular themes.
Material Advantages
 |
PVC is durable and can be used for
long-lasting toys. |
 |
PVC is versatile. It can be used for both flexible
and rigid toys, with kaleidoscopic colors and can be formulated
to get the exact performance and quality requirements. |
Costs advantages
 |
PVC toys can be mass-produced. |
 |
PVC toys allow design flexibility. |
PVC Toys Are Safe
 |
PVC meets all international standards
for safety and health. |
 |
It has been used for more than 40
years and is the world's most researched and thoroughly tested
plastic. |
 |
Studies have shown that there is no
health risk to children playing with PVC toys. |
 |
At the end of its useful life, it
can be recycled. Lifecycle analysis has shown that PVC is a
very competitive and environmentally acceptable material. |
Alternatives To PVC In Toys
Based on the scientific study and the advantages PVC offers
in toys, there are no substantial reasons to replace PVC. All substitutes
without proven technical and safety, would require additional research,
that usually leads to higher cost.
Plasticizers
What are plasticizers?
A plasticizer is a substance which when added to a material, usually
a plastic, makes it flexible, resilient and easier to handle. Modern
plasticizers are synthetic organic chemicals; esters, such as adipates
and phthalates. More importantly, they are not just additives (like
pigments or fillers), they are major components that determine the
physical properties of polymer products.
Plasticizers are also used in rubber products, paints, printing
inks, adhesives, lubricants and some cosmetics. However, the majority
of plasticizers are used in the production of flexible PVC.
Plasticizers include primary plasticizers and secondary plasticizers.
Secondary plasticizers, also known as extenders, do not impart flexibility
to the PVC resin alone and are combined with a primary plasticizer.
Primary Plasticizers
Usually plasticizers mainly refer to primary ones. They include:
 |
Adipates: for low temperature
applications, cost higher . |
 |
Phosphates: low volatility,
but mainly for fire retardant purpose because of cost concerns |
 |
Phthalates: currently the most
commonly used plasticizers |
 |
Trimellitates: usually
for high temperature applications like cables and wires |
 |
Sebacates and Azelates: limited
to superior low temperature applications |
 |
Citrates: medical equipment
and packaging film |
Ban of phthalates
Phthalates
The most commonly used plasticizers are phthalates. They are colorless,
odorless liquids and their principle use is to soften the popular
plastic, polyvinyl chloride (PVC). Plasticized PVC is used in a
wide range of applications such as medical tubing and bloodbags,
footwear, stationery goods, flooring and wall-coverings, electrical
cable insulation, clothing and toys.
Resulting from the issue of phthalate plasticizers, many countries
in Europe have imposed bans on phthalates to different degrees.
Some countries have simply banned PVC toys designed to be put into
the mouth of children under three years of age. Many others have
cautiously limited the amount of phthalates to 0.05% (500ppm) of
individual or total six phthalates, DINP, DNOP, DEHP(or DOP), DIDP,
BBP and DBP). EU risks assessments are expected to be available
in early 2001.
In the USA, according to ASTM F963, pacifiers, rattles and teethers
that contain more than 3% DEHP are banned.
Alternatives
As public debate continues, toy manufacturers are trying hard to
find alternative plasticizers to phthalates, rather than give up
using PVC in toys. This is because of the irreplaceable benefits
PVC offers in toy applications. Currently the most commonly used
alternatives to these six phthalates are:
 |
Benzoates |
 |
Citrates |
 |
DINA |
 |
EPZ (Edible Plasticizer) |
 |
TXIB Plasticizer (commonly called hard oil) |
 |
168 Plasticizer |
