A few of their paints do contain MI / MCI, but many do not. AURO UK are now the sole UK distributor of the paints. On the site, you can view the TDS (technical data sheet) for the individual products, and see ingredients listed under ‘Composition’. The isothiazolinone preservatives are listed as ‘thiazoles‘ so avoid any including this word. For example, the Auro 320 clearly includes them so is unsafe.
The Auro 328 (wall paint, right) is safe, and has had some good anecdotal feedback. Among the other safe options, confirmed by Auro UK in April 2019, are the 250 (gloss paint), 260 (satin paint), 301 (plaster primer), 321 (white wall emulsion), 331 (clay paint), 344 (lime paint) and 505 (grip coat).
For further information on suitability, you can email Auro at email@example.com
Biofa (UK / Ireland)
All except one Biofa paint type are free of isothiazolinone preservatives (the unsafe one is called Primasol). One which is confirmed safe is the Biofa Solimin, which is a silicate-based mineral paint which UK stockists GreenSteps have told us has “several satisfied MI customers”. You can obtain it from GreenSteps Ltd directly, who told us the price is £7-10 per litre, depending on the colour used. In Ireland, the paints are available from Biofa Ireland.
“Zero VOC” interior and exterior paints, which some MI-allergy folk have found works well for them. Declare ingredients on their site, and appear to be isothiazolinone-free. Use propylene glycol as a preservative in some products. See their website here, and for their SDS sheets / ingredients, see here.
Dab Paints (UK)
Soya-bean-based furniture paint in 20 colours. Dab Paints told us their products are free of cellulose thickener, therefore don’t require preservative, and confirmed all paints are free of all isothiazolinone derivatives. See their website for options. See this post on our Facebook page for further information.
ECOS Paints (US)
“None of our paints, primers, stains or varnishes use isothiazolinone preservatives” ECOS paints told us, having been reformulated to exclude the preservatives a few years ago. No old stock should now remain. The paints are also Zero VOC, odor-free, organic and sustainable. See their website for further details. Also available on Amazon.
Edward Bulmer Paints (UK)
Edward Bulmer Paints have a good reputation among MI-allergy folk in the UK, but changes to their products in recent years has meant that it is not easy to summarise which of their products are and aren’t suitable.
We were advised the best thing to do as of April 2019 is to call the offices on 01544 388535 or email firstname.lastname@example.org

Eico (UK / Europe)
Icelandic paint — gloss, matt, emulsion, primer — which ahead of launch told us it would be isothiazolinone-free. Since then, I have followed up now that it has launched, but have not had a reply. Reader Alison separately contacted them, and was given the following response, which I take to mean that coloured varieties do contain low levels of MI, but uncoloured do not. Check before you buy. Find the UK website here. It’s also stocked by Celtic Sustainables.
Eco-colour made with water, minerals and renewable raw materials — but no isothiazolinone preservatives. Click here for more information (in Swedish).
This brand told us the following (June 2019; our emphases):
“Graphenstone ‘Ecosphere‘ & ‘Biosphere‘ as well as Ambient Pro (pure lime and graphene white emulsion for interior / exterior) in White, are free from isothiazolinone preservatives.
“Graphenstone colour ranges, GrafClean & GCS, contain tiny amounts in the tintable bases. Both Coltec B (APEO free) and C (APEO and VOC free) pigments typically contain a tiny amount of these preservatives. This may still have an effect on people with extreme reactions to these chemicals, however, the amounts will be trace.”
To view and buy, click through to the Graphenstone website, then choose your region.

Lakeland Paints (UK)
Their untinted Limewash Paint is free from isothiazolinones, and costs just over £50 for 5 litres. You can order in colour versions, but the pigments used to achieve those colours contain 60 parts per million of MI (60ppm). When added to the neutral unpigmented paint, it is “normally in the less-than-1% range” we were told by Lakeland. That means that the tinted limewashes will contain around 0.6ppm, or 0.00006% MI. This is very low, but not ‘free’.
