Additional information
Skin irritation/corrosion
Glycerol monomyristate (CAS 27214 -38 -6) was tested for its skin irritation potential according to OECD Guideline 404 and in compliance with GLP (Stearinerie, 2000). Three New Zealand White rabbits were exposed to 0.5 g of the crunched test substance in mineral oil for 4 h under semi-occlusive conditions. The vehicle was similarly applied to the other site of the animals and served as control. Skin reactions were assessed using the Draize scheme 24, 48 and 72 h after removal of the test substance. Slight erythema was observed in 2 of 3 animals 24 and 48 h after patch removal, which was fully reversible within 48 and 72 h, respectively. In the third animal no erythema was observed. No oedema occurred in any of the tested animals and no skin reactions were observed on the control sites of the animals treated with the vehicle alone. All animals showed the expected increase in body weight and no clinical signs of toxicity were observed during the experiment. The individual mean erythema scores over the 24, 48 and 72 h reading time points were 0.3/0/0.7 and edema scores were 0 for the 3 animals, respectively. Thus, the test substance is considered to be non-irritating to the skin.
Eye irritation/corrosion
Glycerol monomyristate (CAS 27214 -38 -6) was tested for its eye irritation potential according to OECD guideline 405 and in compliance with GLP (Stearinerie, 2000). The solid test material (0.1 g) was ground to a fine dust and instilled into the conjunctival sac of one eye of three New Zealand White rabbits each. Examination of the effects on the eyes was scored 1, 24, 48 and 72 h after test substance instillation according to the method of Draize. Slight to moderate redness of conjunctivae occurred in all three tested animals, which was fully reversible within 72 h. At the 1 h reading time point, slight chemosis was observed in all animals, and persisted in 2 of 3 tested animals up to 24 h after test substance instillation. However, chemosis was fully reversible within 48 h in all animals.During the 72-h observation period; no clinical signs of toxicity were noted. The mean cornea and iris scores after 24, 48, and 72 h were 0 for all 3 animals. The mean scores for conjunctivae and chemosis over 24, 48, and 72 h were 1/1/0.7 and 0/0.3/0.3 for the 3 individual animals, respectively. Thus, the test substance was not considered as eye irritant.
Justification for classification or non-classification
According to Article 13 of Regulation (EC) No. 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met. Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that "substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint". Since the analogue concept is applied to Glycerol monomyristate, data will be generated from data available for reference source substance(s) to avoid unnecessary animal testing. Additionally, once the analogue read-across concept is applied, substances will be classified and labelled on this basis.
The available data on skin and eye irritation/corrosion do not meet the classification criteria according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification.
