Sonett Organic Curd Soap (3.5 fl. oz/100g) ( Pack of 2 )( Pack of 28)


For household use and workshop

  • Mild inexpensive hand soap made 
    from organic vegetable oils
  • Without any colourings, fragrances, fillers, 
    complexing agents or optical brighteners

  • Lasts for a long time
  • Fragrance-free and vegan


Special product feature

This curd soap is manufactured without using fillers, dyestuffs, fragrances, optical brighteners, and, above all, without any petrochemical complexing agents such as EDTA. It is thoroughly matured before being put on sale which increases its shelf life.

The slightly brown colouration of curd soap when stored for several years is a sign of the purely natural quality of this product and, in no way, impairs its quality and washing performance.

Ranges of application

For household use and workshop areas as well as wherever durable, effectively cleansing hand soap without any additives is needed.


Purely vegetable, fragranc-free organic soap for washing hands, face and the entire body.

Even when using the curd soap with cold and hard water it develops a high degree of cleaning effectiveness. The hardness of the soap impedes its becoming soggy despite possibly lying on a wet surface for a while.

Origin and properties of the ingredients

Soap being an active washing substance, it is obtained by simply boiling fats with alkaline solution. Every fatty base differs in its washing properties somewhat from another because of their diversity of origin. Coconut-oil soap, e.g., possesses a very good cleaning performance, even in cold and hard water; and soap made from palm oil contributes the required firmness to the soap which prevents it from quickly becoming soggy when the soap happens to be left on a wet surface for a longer period of time.

Technical data

Soap is slightly alcalic in its use.



Soap is the only active washing substance which right after its use loses its surfactant properties under direct reaction with limescale which is always present in waste water, thus becoming non-toxic to live aquatic organisms (primary degradation). The calcium soap (formed by the reaction) is then 100% micro-organically decomposed into carbon dioxide and water (secondary degradation).

Soap is classified as being readily biodegradable according to OECD guidelines.
