Description of key information

Additional information

Zinc dilaurate is a white, odourless powder with a melting point of 123°C.The decomposition of zinc dilaurate started before boiling at 320°C. Thus, a boiling point could not be determined.The relative density of zinc dilaurate is 1.18. As the substance is a salt with a melting point of 123°C, vapour pressure can be safely assumed to be negligible, i.e. below the level of relevance (10-5 Pa). Zinc dilaurate is a surface-active substance. The water solubility of zinc dilaurate ranges from 5.2 to 6.4 mg/L, resulting in zinc concentrations ranging from 0.7 to 0.9 g/L. The partition coefficient of this substance is not considered to be relevant. Zinc dilaurate is not flammable. Flash point, explosive properties, self-ignition temperature, oxidising properties, stability in organic solvents and identity of relevant degradation products as well as dissociation constant and viscosity are not relevant for this substance in accordance with column 2 of the respective sections of Regulation (EC) No 1907/2006, Annexes VII to IX or Annex XI, section 1. The granulometry of a representative test material is summarized as follows:

D10 = 4.3 µm

D50 = 16.7 µm

D90 = 34.8 µm

Zinc dilaurate does not need to be classified for physico-chemical properties, neither according to Directive 67/548 EEC nor to CLP Regulation (EC) No 1272/2008:

zinc dilaurate is not flammable;

explosive properties are considered non-relevant based on lack of explosive properties;

oxidising properties are considered non-relevant based on the chemical structure.


The structural analogue substance "Fatty acids, C16-18, zinc salts (CAS# 91051-01-3), relevant for read-across to zinc dilaurate, was subject of a EU Risk Assessment. Conclusions from EU RAR Zinc stearate (CAS# 91051-01-3, CAS# 557-05-1) Part I - Environment (Final report R074_0805_env, May 2008; in line with the conclusions for zinc dilaurate:

“Data on boiling point, vapour pressure, and surface tension were not provided. In view of the nature of the substance determination of these parameters is considered to be irrelevant. Information on flammability, explosive properties and oxidizing properties is not available. However, on theoretical considerations the compound is concluded to be not flammable, not explosive and not oxidizing.”
