Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
Fatty acids, coco, reaction products with N,N-dimethyl-1,3-propanediamine represent a mixture containing C8-, C10-, C12-, C14-, C16-, and C18-alkyl side chains. Based on this and the variable composition of the compound (alkyl chain distribution dependent on origin of the coco fatty acid) the calculation of physico-chemical properties for the mixture is not feasible. To get a hint on the physico-chemical data, a calculation was conducted for the C8, C12 and the C18 derivates. The vapour pressures of the C8, C12 and C18 derivates were calculated using EPIWIN v4.0, MPBPWIN v1.43.

Any other information on results incl. tables

Fatty acids, coco, reaction products with N,N-dimethyl-1,3-propanediamine represent a mixture containing C8-, C10-, C12-, C14-, C16-, and C18-alkyl side chains. Based on this and the variable composition of the compound (alkyl chain distribution dependent on origin of the coco fatty acid) the calculation of physico-chemical properties for the mixture is not feasible. To get a hint on the physico-chemical data, a calculation was conducted for the C8, C12 and the C18 derivates. Vapour pressures of 9.86 x 10E-4 hPa (7.4 x 10E-6 mm Hg; C8 derivate), 3.96 x 10E-7 hPa (2.97 x 10E-7 mm Hg; C12) and 2.23 x 10E-9 hPa (1.67 x 10E-9 mm Hg; C18 derivate, at 25 °C each) were calculated using EPIWIN v4.0, MPBPWIN v1.43. Due to missing information about the applicability of the calculation model in respect to the substance under investigation the results should be treated with care.
