How come IsoPropyl alcohol is considered a VOC but not Ethyl alchohol?

The BT Artbox Story
The good old British phone box was designed by Sir Giles Gilbert Scott to commemorate King
George V’s Silver Jubilee.
This year we’ve got a Diamond Jubilee and London 2012 to look forward to, so we decided we needed to do something to celebrate.
That something turned into BT ArtBox. It’s a campaign that thrives on the nation’s artistic talent.
Across London’s streets you’ll find replicas of the Gilbert Scott phone box, transformed by the
imaginations of some of our very best creative minds.
Then later on we’ll be auctioning all the boxes off to raise money for ChildLine’s 25th anniversary.

Location: Old Spitalfield’s Market
This sweet scent of memory,
green hills and pleasant seems
the cool dew in distant dreams of birdsong,
nostalgia bathes the scene,
And my heart belongs to thee.
Within this soft and satin world
these tears will dry and leave no stain,
as rain implores the sun
to kiss your hair, your face and hands
a feather’s touch upon the skin.
Of diamond edge and gilt refrain
a pledge of life and love,
to the follower of dusty trails
across the sea, the land, the sky
the Seeker seeks and so will Find.
Mighty as the Queen of Bees
gold dust heavy on silver wings
a diamond hard, will cut it seems
fair and foul and fair again
uphold the laws of majesty.
We journey long, as far as eyes can see
beyond which, time is light and air
all full to brimming through Englands green,
rose tint in the mirror sheen
romance the fire and melody.
Of suns rise and sets full
moons and stars all things forgot
just look beyond the here and now
the dream is all, safe and warm
in hope, for peace and charity of soul.
For here is Life and Love and All You Ever Dreamed Of.

Isn’t it? I’d think it would be.
It’s possible that the proportion of oxygen in an ethanol molecule is enough that it’s not considered volatile carbon. The proportion of oxygen in isopropanol is less.

Isopropanol has a high vapor pressure therefore it tends to evaporate easily. Ethanol also evaporates easily and is considered a Volatile Organic Compound.
Infact adding ethanol to a petrol mix raises the overall level of hydrocarbon emissions (VOCs) from the gasoline.
Also ethanol is not environmentally safe to fuel cars because the burning of ethanol produces Carbon dioxide, this is involved in global warming.

NB: ethanol is present in very small amounts in alcoholic beveridges, and the ethanol that is used is ethanol BEE.

Let me add…
100% ethanol is a volatile organic compound. But it is very hard to obtain. If forms an azeotrope with water and by distillation the purest you can obtain when it is mixed with water is 95% ethanol. Still somewhat volatile at 95%, but not as much as pure ethanol due to the H-bonding and association with water.
Booze, and hard liquor are 80 proof (which is only 40% alcohol/water).
If you were to drink 95% ethanol, it would burn the back of your throat – like you never would believe!
