MSDS ingredients

Well organic solvents, water and a surfactant.

Probably cheaper to mix your own

Once you know which solvent(s) to use, yes. I've run out of trike now, but have plenty of IPA and a litre of butyl acetate looks about the same price as 100ml of the leather cleaner, so I might try it next time I need some.

the surfactant looks a lot cheaper in bulk than e.g. washing up liquid too...

It's very strange that it isn't in the MSDS. However, the MSDS I found was for the aerosol (

The one I found was at

The MSDS lists the IPA as 1-5% (they don't seem to ever be exact) and the other ingredient list showed the acetate last in the list, so presumably a lower amount, so is there a cut-off percentage that doesn't need mentioning? The smell is pretty noticeable

If the smell is pretty noticeable, why does that MSDS refer to the odour in Section 9.1 as "Alcohol odour"! If butyl acetate is like isoamyl acetate it should have a pretty strong fruity smell. In fact, at

I wouldn't be surprised that if butyl acetate is below a specific level it's concentration doesn't need to be mentioned in the MSDS.

Esters are smelly in quite low concentrations, so I'd not be surprised if it's sufficiently low to not need mentioning. LD50 is 10.8g/kg so the toxicity of such a weak solution probably wouldn't be an issue.

But I agree, if the MSDS mentions odour then I'd have expected it to be described, even if the components responsible for the odour aren't specifically identified.

I wouldn't claim to be able to tell ethyl/isoamyl/butyl acetate odours apart, but it's one of that family.

I remember a TV programme from many years ago, that demonstrated that it was possible to generate a third and quite different smell from two others.

The experiment involved something like 11 test tubes in a line, the one at one end was filled with 100% of one aromatic liquid, at the other end 100% of a different aromatic liquid, with mixtures in between decreasing in proportion in order from one end to the other.

The outcome was independently tested and found that the mixture in the test tube in the middle smelled completely different to all the rest, such as that of oranges, when neither of the two liquids had any relationship with that fruit.

It’s just possible your nose is being misled…

Better make sure it's all evaporated from your shoes before you go out. ;-)

May well be possible

Don't forget that despite what the MSDS didn't list, the website did say it contains butyl acetate
