Executive summary:

The particle size distribution of the test item 'Decanoicacid, 3-[[6-deoxy-2-O-(6-deoxy-α-L-mannopyranosyl)-α-L-mannopyranosil-1-(carboxymethyl)octyl ester, mixture with 1-(carboxymethyl)octyl 3-[(6-deoxy-α-L-mannopyranosyl)oxy]-decanoate' was determined by laser light scattering, according to OECD Guideline 110 (and ISO 13320 and OPPTS 830.7520). The test material has a median particle size of D50 = 15 µm.

Description of key information
