As part of its responsibility to consumers, the Australian tea tree
industry adheres to stringent legal requirements than ensure the quality
and safety of its products.
Pure tea tree oil of more than 15ml
in volume is bottled in ribbed dark glass bottles and fixed with a
child-proof safety cap. Tea tree oil sold in clear glass bottles of
greater than 15ml volume is not 100% tea tree oil. Pure tea tree oil
should only be stored in clear glass containers for limited periods
of time, as over-exposure to light will degrade its quality.
As members of the Australian tea tree industry are commited to excellence, all efforts are made to ensure that loss of quality does not occur during production, packaging and transport of their products.
Note that such regulations do not always apply to tea tree oil produced
and bottled overseas.
