Nothing to Hide Every Ingredient, Declared Transparency is fundamental to the way we make paint. Rather than hiding behind broad descriptions, we tell you what goes into our formulations so you can make an informed choice about the paint you use in your home. Our paints are made with a pioneering plant-based binder and coloured using carefully selected earth and mineral pigments. Natural Emulsion Water The primary diluent for most natural paints – and ours is no exception. Water makes up nearly 80% of our emulsion, helping it apply smoothly and dry evenly. Sourced: Harz Mountains, Germany Castor Oil Extracted from the seeds of the subtropical castor oil plant (Ricinus communis), then boiled to create a natural drying oil, also known as Turkey Red Oil. It enhances durability and flow. Cellulose A natural starch derived from wood pulp from sustainably managed European forests. Used as a thickener and emulsifier in our natural paints. Sourced: Europe Chalk A soft, white mineral (calcium carbonate) ground to a fine powder and added as a natural filler to improve opacity and texture. Sourced: Germany Clays Naturally occurring minerals formed from the weathering of rocks rich in aluminium and silica. We use china clay (kaolin) and bentonite to thicken our paints and help pigments stay evenly suspended. Sourced: Germany Replebin® Our exclusive biogenic binder — made from plant alcohol esters and organic acids. Replebin makes our natural paints durable and easy to apply, while retaining highly vapour permeable (breathable) properties. It’s a legally protected innovation and only available from our manufacturer, AURO. Sourced: Germany Silicates Mineral-based fillers like mica, clay, and quartz (silicon dioxide) that add body to the paint and strengthen the finish. Also help keep pigments in suspension. Sourced: Germany Sodium Pyrithione An organic compound containing sulphur and nitrogen, used as a mild preservative to extend the shelf life of our paints. Commonly used in cosmetics, cleaning products and paint. Sourced: Europe Surfactants These important ingredients keep oils in suspension and improve the workability of our paints. They are also used in the processing of resin-binders in our water-based eggshell. We make ours from rapeseed oil, castor oil, and sugar-rich plant materials. Sourced: Germany & Asia Titanium Dioxide Highly opaque, non-toxic white pigment universally used in paints and lacquers (and many other products including toothpaste). Refined from natural minerals (e.g. rutile) in an acid-free process, it nonetheless has a significant ecological impact. Sourced: Europe & Asia Benzisothiazolinone (BIT) An organic compound containing sulphur and nitrogen. Used to preserve products e.g. in cleaning agents, paints and cosmetics. Water-Based Eggshell & Gloss Water The primary diluent for most natural paints – and ours is no exception. Sourced: Harz Mountains, Germany Alkaline Solution A solution of ammonia in water, used for making water-dilutable resins, waxes and oil soaps, so-called ammonia soaps. Sourced: Europe Bio-based Binder A unique plant-based binder developed exclusively for AURO. Made from plant alcohol esters of pine and castor, with a small amount of fossil-derived monomers. It’s constantly being refined to become fully biogenic — a scientific breakthrough unmatched in the paint industry. Sourced: Germany Cellulose A natural starch derived from wood pulp from sustainably managed European forests. Used as a thickener and emulsifier in our natural paints. Sourced: Europe Silicates Mineral-based fillers like mica, clay, and quartz (silicon dioxide) that add body to the paint and strengthen the finish. Also help keep pigments in suspension. Sourced: Germany Silicic Acid Finely dispersed silicic acids without crystaline (quartz) structure made from quarts sand and lime by flame hydrolysis. Used as matting filler or as filter agent and binder additive in silicic brines. Sourced: Germany Sodium Pyrithione An organic compound containing sulphur and nitrogen, used as a mild preservative to extend the shelf life of our paints. Commonly used in cosmetics, cleaning products and paint. Sourced: Europe Surfactants These important ingredients keep oils in suspension and improve the workability of our paints.

Sourced: Europe & Asia Benzisothiazolinone (BIT) An organic compound containing sulphur and nitrogen. Used to preserve products e.g. in cleaning agents, paints and cosmetics. Real Earth & Mineral Pigments Colour begins with pigment. Rather than relying on a vast spectrum of modern synthetic colourants, we create our palette from a carefully selected range of earth and mineral pigments, with roots in the historic pigment palette. Their traditional equivalents include Flake White, Chrome Yellow, Yellow Ochre, Raw Sienna, Red Lead, Red Ochre, Vermillion, Violet Carmine, Prussian Blue, Ultramarine, Verditer, Viridian and Lamp Black. Used in different combinations and proportions, this carefully chosen palette of pigments gives our colours their distinctive tonal relationship and remarkable response to changing light.
