Link to relevant study record(s)

Reference

Endpoint:

relative density

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

no guideline followed

Principles of method if other than guideline:

Sample substabce was melted and cast into a solid block, whose dimensions could be accurately measured. The mass of the block is measured and the relative density calculated. Approximately 30 g of sample was used for each test.

GLP compliance:

no

Type of method:

other: Casting substance into a regular cylindrical block

Type:

density

Density:

ca. 0.98 g/cm³

Temp.:

20 °C

Type:

bulk density

Density:

ca. 0.624 g/cm³

Temp.:

20 °C

Test 1: Density  of solid sample at 20°C = 0.979 g cm-3       

Test 2: Density  of solid sample at 20°C = 0.982 g cm-3

Test 3:       Density  of solid sample at 20°C = 0.980 g cm-3       

Average density of solid sample at 20°C = 0.980 g cm-3       

Test 1:       Bulk density of granular sample = 0.624 g cm-3

Test 2:       Bulk density of granular sample = 0.625 g cm-3

Test 3:       Bulk density of granular sample = 0.624 g cm-3

Average bulk density of granular sample at 20°C = 0.624 g cm-3

Conclusions:

The relative density study was performed by casting substance into a regular cylindrical block and it was reported as 0.979 g cm-3 at 20°C. The bulk density of granular sample was performed with a pyknometer device and it was reported as 0.624 g cm-3at 20°C

Executive summary:

Two studies were undertaken to determine both the relative and bulk density of test item Fatty acids, C16 -18, reaction products with ethanolamine. The relative density study was performed by casting substance into a regular cylindrical block and it was reported as 0.980 g cm^-3 at 20°C. The bulk density of granular sample was performed with a pyknometer device and it was reported as 0.624 g cm^-3 at 20°C
