- Conclusions:
- The water solubility of dicyandiamide at 20 °C is 3.2 g/100 g water. Therefore, dyciandiamide is classified as very soluble (> 10000 mg/L).
- Executive summary:
The information is taken from a handbook (Ullmann's Encyclopedia of Industrial Chemistry).
Dicyandiamide has a solubility of 3.2 g/100 g water at 20 °C and is classified as very soluble.

Interpretation of results: very soluble (> 10,000 mg/L) - Executive summary:
The information is extracted from a collection of data from the American Cyanamid Company. The water solubility is given in g per 100g water for 4 different temperatures (25, 49.8, 74.5, and 100°C) respectively. As the water solubility at 25°C is 4.13g/100g water is higher than 10,000mg/l, dicyandiamide is very soluble in water.

Description of key information
The information is taken from a handbook (Ullmann's Encyclopedia of Industrial Chemistry) as well as from a collection of data (American Cyanamid Department).
Key value for chemical safety assessment
- Water solubility:
- 32 g/L
- at the temperature of:
- 20 °C
Additional information
The handbook data states a water solubility of 3.2 g/100 g water at 20°C.
The collection of data states a water solubility of 4.13 g/100 g water at 25°C.
The results of both sources are scientifically in line. The higher value from the collection of data can be explained by the increased temperature of 5K. As both values are above 10000 mg/l water, dicyandiamide can be classified as very soluble.
