D-glucono-1,5-lactone

Particle size distribution (Granulometry)

Description of key information

Particle size distribution (key study): Mean distribution at 10% = 100-150 µm; 50% = 200-300 µm; 90% = 380-420 µm.
 
Mass Median Diameter (supporting study): 227.8 µm

Additional information

Based on the information obtained from a key study by Puech (2010), using sieve method, the mean value for test substance particles with a diameter below 100 µm was 4.6% (three batches were tested). In a supporting study conducted according to the French standard NF X 11-666, the test substance Mass Median Diameter was reported as 227.8 µm. In addition, there is material on the market with slightly lower granulometry (approx. mean value at 10% = 75 µm, 50% = 160 µm, 90% = 240 µm) which is considered to be safe when used under standard operating conditions.
