Sonett is a trusted name for their utmost care for the environment - there are few manufacturers who can make the claim to being 100% biodegradable like Sonett can.

Highly effective liquid for removing stains and spots caused by fruit, blood, ink, ballpoint pen, grass, and grease, etc.

Suitable for all white and colour-fast textiles made from cotton, linen, hemp and fabric blends. (Before washing coloured textiles, test their colour fastness on a concealed spot.)

Unlike the gall soap bar, Sonett liquid soap may be added to a machine wash cycle. As a wash intensifier: For washing at 30–60 °C (85–140 °F), add 20–30 ml (1 fl oz US) to the main wash cycle of the 4.5 kg (10 lb) washing machine.

For local treatment of stains: Apply undiluted liquid gall soap to the stain and allow taking effect for 10–15 minutes. Wash out thoroughly or place the garment straight into the washing machine.

120 ml liquid in a plastic bottle.

Origin and properties of the ingredients

Bovine gall is a traditional stain remover. Its principal active ingredients, i.e. the bile acids cholic and taurocholic acids, are not only capable of finely dispersing grease and fat-like substances but also of dissolving dyestuffs and forming compounds with them. Soap manufactured from rapeseed / sunflower oil and olive oil with lye (alkaline solution), swells and dissolves the dirt and supports the stain-removing performance property of the bovine gall. Sugar surfactant is obtained from pure plant-based raw materials–sugar, starch and coconut oil– and their chemical reaction with acids. Citric terpene derived from orange peels intensifies even more the fat-dissolving property of Sonett Gall Soap.

Bovine gall being a purely natural product is 100 % biodegradable. Soap made from plant-based oils has the unique property that, right after its use, it reacts chemically with the limescale always present in waste water, thus forming calcium soap. As a result, the surfactant effect inimical to aquatic organisms is being neutralised within a few hours (primary degradation). Subsequently the calcium soap is, by microorganisms, 100 % decomposed into carbon dioxide and water (secondary degradation).

Despite the fact that during the manufacturing of sugar surfactants and coconut oil alcohol sulphate, constituents are being extracted from the plant-based raw materials starch, sugar, and fat, they remain completely intact in their natural molecular structure. For this reason it is relatively easy for the microorganisms to 100 % decompose these surfactants.

Soap and sugar surfactants are classified as being readily biodegradable according to OECD guidelines.

Suitable for septic tanks and filtration systems.
