  Help with particle size, please

  Posted by MariaGarcia on April 4, 2022 at 3:09 pm

  Hi everyone.

  I want to buy non-colloidal microcrystalline cellulose for a toothpaste. I’m reading the data sheet but I don’t know how to interpret the particle size, can someone help me? On the data sheet it says:

  Particle size (um distribution by laser):

  D10: Not more than 50

  D50: 90-140

  D90: Not less than 170

  Thank you very much!

  I understand this as sort of bell curve like distribution
  10% to be less than or equal to 50 (insert your units here), 50% of your product around that 90 - 140 mark, and then 10% to be equal to or greater than 170 (your units here)
  (To extrapolate that would leave 15% for both the 50-90 and 140-170 range)
