These days correction fluids like Tippex seem to have been reformulated
compared to several years ago.
I think the old chemicals used were too hazardous and the dilution fluid
for them was something hazardous like 1,1,1 trichloroethylene.

I have some new style Tippex Rapid and it has started to thicken.

What household solvent can I use to dilute it?
(1) Isopropyl alcohol doesn't do it.
(2) Acetone didn't seem to work.
(3) I think ethyl acetate (nail polish remover) might have worked
although it was getting hard to tell after 1 and 2. But it smells
hazardous.
What can be used?

Have you tried water?

Yeah.
"New & Improved" is always a wow.
They banned tippex thinners when I was in school due to the kids
sniffing it !!
IIRC, the correct, and politically incorrect solvent for proper Tippex
(not the girl's school version) is Toluene.
Apparently it clears sinuses as well....
That sounds similar to "White-Out" in the US, and my comments below assume
the UK version is similar to the US version.

While that name is chemically impossible, I believe the solvent used to be
either 1,1,1-trichloroethane or 1,1,2-trichloroethylene. In my youth, my
dad worked in an AEP research lab, and he used to bring pints of what he
called "trichlor" or "electrosol" home, but it was never clear to me whether
it was the -ane or the -ene. Both have very similar physical properties and
chemical properties. While both are very weak acute toxins (LD50 is on the
order of 6 g/kg), they have longer-term effects (carcinogen, teratogen and
mutagen). Too bad, because nothing beat the stuff my dad brought home for
cleaning my bicycle chain. I tried methylene chloride in grad school, but
it evaporates too quickly and leaves too much grit behind (not to mention
the burning sensation under my watch band.) Trichlor floated the grit right
away, leaving smooth metal behind for re-greasing.
The new White-Out (now sold in the US as "correction pens" that dispense
white ink) smell to me like they still contain some chlorocarbon (maybe
trichlor)...it may be that nothing but chlorocarbons form stable suspensions
with the TiO2 (or is it ZnO2?). I also think I smell some toluene and some
ketone, perhaps MIBK. The label says "Contains petroleum distillates",
which could be the toluene. When the stuff dries, it smells like linseed
oil, which may be the binder that keeps the TiO2 (or is it ZnO2) from
crumbling away. By smell, it is a real gemisch of solvents.
It may be that no safe solvent works especially well, because more and more,
I'm seeing pen-dispensed correction tape replacing the correction fluid.

Actually, ethyl acetate is probably the least hazardous of those three you
tried. If it works, I'd go for it. (I used to really like the smell of
ethyl acetate, until one time the airlock went dry on a batch of wine I was
making, and the air exposure converted a detectable amount of the ethanol to
ethyl acetate. It smelled pretty, but boy did it taste awful.
I've used methylene chloride to rejuvenate White-Out in the past. It
resuspends the pigment very well, but it doesn't work great--it evaporates
too quickly. I would try some trichlor (electronics supply shop?) or
methylene chloride (hardware store, as furniture stripper), or maybe toluene
(hardware store--paint thinner or lacquer thinner).

It was 1,1,1-trichloroethane.

Yes DCM will work. You need a halogenated solvent for Tippex.
DCM also tends to make the plastic bottle a bit "soft" and it dries way too
fast.
I would guess dichlorethane or maybe perchlorethylene would work well

I really dislike those things!
Nah, in the good old days, they used mimeograph for school duplication. A
good snootful of chlorinated ink solvent really put one in the mood for
excellent performance on an exam.

The last bottle of TippEx I used was water based.
It took ages to dry but worked OK.
It is a problem on some washable inks as they wick through.
Of course if you are going to use the sort of solvents mentioned in this
thread so far you could probably use hydrogen peroxide and bleach the ink
from the paper (doesn't work with lasers but a hot iron works wonders).
And what a great smell it was. Couple that with Tipex thinners and I'm
amazed that any of us from that era actually made it to adult-hood :o)
Isn't it called "Liquid Paper" in the USA. I believe that it was
invented by the mother of Mike Nesmith - the one with the wooly hat out
of The Monkees!

Wouldn't it be easiest to go and buy a new bottle of the stuff? It's
quite cheap, you know!

Oh I don't know.
I once knew a blonde secretary who had Tippex all over her PC monitor screen
And a pain to chip off the screen.

I remember an electronic typewriter that wrote like that. It would do
graphs etc - *slowly*

Got to ask but why dilute ?
