Methylisothiazolinone Free Paints

Auro (Europe)
A few of their paints do contain MI / MCI, but many do not. See this statement on the Organic Natural Paint website for more information and a list of unsafe products, although note that this statement is now well over a year old, so double check before you buy. Their key UK stockist is Ecolour (formerly Auro UK). 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 (right) is safe, and has had some good anecdotal feedback. 

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 Biochrome

Edward Bulmer Paints (UK)
Their 72 colours are available in six finishes – three of which are MI-free. These three are water-based eggshell, oil-based eggshell and oil gloss. (You can choose one of these three options once you have chosen your colour.)

Furthermore, some preparatory products are MI-free. These are water-based undercoat, oil undercoat (in white and grey), and wood primer
