which paint make is the best for non toxic?

[imiami]

I am going to paint internal wall for bedroom, which make/brand is the best? non toxic? water based?
shall I order colour tester first? as I need a few different colour paint.
is august good month to paint in UK？
Many thanks

Heat is not great for painting.

All wall and ceiling paint is water based

Toxic paints are now phased out.... which would be oil based

Thanks, so September better?

Little Greene is known to be very child-safe

I used Ecos paint- they now seem to be called Lakeland paint on the uk site:

Lick seem to be good.

For as low “toxic” as possible you want water based and look at the back for the low VOC level.

when you’ve finished painting make sure you either keep, pass on it safely dispose of your leftover paint (council will have guidance).

Earthborne is really good. I am very sensitive to smell and this is the one that is least irritating from the many paints I've tried. I can recommend little greene too.

I'd be wary of paying a premium for paints with 'natural' pigments on the assumption they're less toxic or generally somehow 'safer'.

Many natural pigments used historically turned out to be very toxic indeed. Lead White, Scheele's Green, Vermilion or Uranium Orange, anyone?

Seconding Earthborn. It's also just lovely paint, with great coverage and a very forgiving super-matt finish.

I second Earthborn. Excellent to put on, too, a real pleasure to use.

I think you'll find those baddies, along with more modern ones, are all banned from household paints, most of them many years ago.
The eco type I use is Earthborn, they seem good to me and I work with pigments, including toxic ones which would not be allowed in household paints, for my job.
If in any doubt, talk to the manufacturer and/or call for the data sheet for the paint in question. All companies have to provide them if asked, and any hazards will be listed. Bear in mind that all pigments are regarded as a dust hazard when in dry pigment form (because you can breathe them in and in that regard all dust is toxic) even if they are non-toxic in paint form. Also, some pigments which are fine for general use may be a problem for those with skin allergies. I have to be careful with paints with cobalt in, for example.
On the whole, if you don't eat the paint and you clean up properly, the biggest hazard is the medium/binder, if it gets into the atmosphere and you breathe it in. That's why the bog-standard paints can be problematic for some people, and why the eco-paints without modern resins etc. in are often better tolerated, though the same thing makes them less hardwearing (but easier to touch up if marked). Earthborn has as close to no smell at all as any paint I have ever used in that regard.
