Test material
- Details on test material:
- - Name of test material (as cited in study report): Methyl (Polyhydroxymethyl) Stearate
- Molecular formula (if other than submission substance): UVCB- not applicable
- Molecular weight (if other than submission substance): UVCB- MW of primary components range from 270- 389 g/mole.
- Smiles notation (if other than submission substance): UVCB- not applicable
- InChl (if other than submission substance): not specified in the report
- Structural formula attached as image file (if other than submission substance): UVCB- not applicable
- Substance type: Mixture of functionalized fatty acid methyl esters (FAMEs), which may be derived from a variety of natural seed oils.
- Physical state: White viscous liquid, semi-solid
- Analytical purity: 95.2 % as summed concentration of five primary components
- Impurities (identity and concentrations): water, approx. 0.4%
- Composition of test material, percentage of components:
Methyl Palmitate – 9.68 %
