I have done even more research.. basically summarised as follows (anywhere i say PET refers to PolyEthylene Therephthalate, polyester used for packaging material. (PET 1) All of the literature applies to the use of the PET in the storage or holding of foods and liquids for human consumption. (The holding of chemicals is refered to in the latter.)
NAPCOR COMMENTS ON THE SAFETY OF THE PET PLASTIC CONTAINER;
Basically states; "PET resin does not contain Bisphenol-A (BPA) nor is BPA used in the manufacture of PET resin. PET resin is classified as a terephthalate compound and is safe for use in food and beverage containers. PET is not associated with orthophthalates or “plasticizers,” a different phthalate subset."

Frequently Asked Questions Relating to PET Plastics ( http://www.petcore.org/faq )
Basically states;
PET does not contain BPA and BPA is not used in PET's manufacture. Factual errors or confusing statements occasionally appear, even n respected publications.
PET and its raw materials are not made from phthalates.
There may be some confusion because the names of the very safe terephthalate and isophthalate sound similar to phthalate, but they are very different compounds.
Considerable research has been conducted with no evidence of danger to reproduction or reproductive development from PET or any of its raw materials. Environmental estrogens are naturally occurring and synthetic compounds that mimic or alter the normal process of the female hormone oestrogen. They have recently received a lot of attention because some questionable studies, which have not been replicated in subsequent studies, suggested that even low doses can cause harm.
These compounds are found in naturally occurring and possibly man-made chemicals that are present in our air, water, soil, food, and the household products we use. PET is not made from these materials.
The research to date does not show harmful effects in people or wildlife, and no government agency has accepted the possibility of harm from low levels of exposure. Exposure to doses that might be associated with adverse effects is not found in our daily lives.
Plastics & Chemical Resistance states;
Benzyl Alcohol pure (liquid) 3 = PET exhibits poor resistance to attack; should not be considered for this application.
Benzyl Benzoate pure (liquid)2 = PET has marginal resistance to attack; significant chance of container failure.

My interperatation is that PET plastics are not suitable for holding either of the above (it refers to PURE)

Polyethylene terephthalate;
Depending on its processing and thermal history, polyethylene terephthalate may exist both as an amorphous (transparent) and as a semi-crystalline polymer. The semicrystalline material might appear transparent (particle size < 500 nm) or opaque and white (particle size up to a few microns) depending on its crystal structure and particle size. Its monomer (bis-?-hydroxyterephthalate) can be synthesized by the esterification reaction between terephthalic acid and ethylene glycol with water as a byproduct, or by transesterification reaction between ethylene glycol and dimethyl terephthalate with methanol as a byproduct. Polymerization is through a polycondensation reaction of the monomers (done immediately after esterification/transesterification) with water as the byproduct.
OVERALL SUMMARY
The BB & BA total of 100ml "dilouted" with gso in solution of 500ml would unlikely degrade in 14 days in the PET 1 container(s). In the event of any miniscule amount of corrosion should not be harmful in comparison to other plastics containing harmful metabolites.
At the moment I am considering trying the preparations. I have to look more in depth at;

its very difficult to disect..
Any opinions? Bill, Millard, guys?
