Form:
solid: particulate/powder
Colour:
White. The colour was classified as N 9.5/90% R using the 31 Step Neutral Value Scale.
Odour:
odourless
Substance type:
organic
Conclusions:
The test item was determined to be a fine, opaque, white solid that was a free-flowing powder but could form clumps and had no discernible odor.
Executive summary:

Using procedures designed to be compatible with Methods 830.6302, 830.6303 and 830.6304 of the OCSPP guidelines, August 1996 the test item was determined to be a fine, opaque, white solid that was a free-flowing powder but could form clumps and had no discernible odor. The colour was classified as N 9.5/90% R using the 31 Step Neutral Value Scale.
