Description of key information
Skin Irritation:
Mild erythema and no edema was observed in rabbits during the 7 days of observation after treatment with propylene glycol oleate.
Hence, propylene glycol oleate can be considered not irritating to male albino rabbit skin.
Eye Irritation:
The ocular irritation potential of Propylene Glycol Mono oleate was estimated using OECD QSAR toolbox v3.4 with logPow as the primary descriptor.
Propylene Glycol Mono oleate was estimated to be not irritating to the eyes of Himalayan rabbits.
Based on the estimated results, Propylene Glycol Mono oleate can be considered to be not irritating to eyes and can be classified under the category “Not Classified” as per CLP regulation.

Additional information
Skin irritation:
In different studies,Propylene Glycol Mono oleatehas been investigated for potential for dermal irritation to a greater or lesser extent. The studies are based on in vivo experiments in rabbits along with predicted data for target chemicalPropylene Glycol Mono oleateand its functionally similar read across substances, Isopropyl Myristate [CAS: 110-27-0] and Glyceryl monooleate [CAS: 111-03 -5]. The predicted data using the OECD QSAR toolbox has also been compared with the experimental data.
A Skin irritation study was performed by Lillian C. Becker(Cosmetic Ingredient Review Washington, DC, August 18, 2014)on albino male rabbit to assess the irritation potential of propylene glycol oleate. The animals were administrated of propylene glycol oleate (1% in tetraglycol: distilled water 1:1, with and without 1% lidocaine). Propylene glycol oleate was administered to the backs (clipped of hair) of the rabbits in adhesive plasters with an exposure area diameter of 1.5 cm2. The test sites were kept under occlusion except when the dressing was removed on days 1, 3, 5, and 7 only long enough for observation. Then sterile pads were changed and the rabbit’s back re-occluded. Mild erythema was observed in animals and no edema was observed during the 7 days of observation after treatment with propylene glycol oleate.
Hence, propylene glycol oleate can be considered not irritating to male albino rabbit skin.
Skin irritation effects were also estimated by four different models i.e, Battery, Leadscope, SciQSAR and CASE Ultra used within Danish QSAR database for Propylene Glycol Monooleate. Based on estimation, no severe skin irritation effects were known when Propylene Glycol Monooleate was exposed to rabbit skin.
In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the skin irritation potential was estimated for Propylene Glycol Monooleate. Propylene Glycol Monooleate was estimated to be not irritating to skin of Himalayan rabbits.
The experimental and estimated results indicate the possibility of Propylene Glycol Monooleate being not irritating to skin.
The above results are also supported by the experimental study summarized in JOURNAL OF THE AMERICAN COLLEGE OF TOXICOLOGY; Volume 1, Number 4, 1982; for the functionally similar read across substance, Isopropyl Myristate [CAS: 110-27-0]. The study was performed according to Draize method.100% undiluted Isopropyl Myristate was applied to the skin of 6 rabbits. The rabbits were observed for signs of irritation (duration not mentioned). No signs of irritation observed after 100% Isopropyl Myristate was exposed to rabbit skin. Hence, Isopropyl Myristate was considered not irritating to rabbit skin.
These results are further supported by the experimental study summarized in JOURNAL OF THE AMERICAN COLLEGE OF TOXICOLOGY; Volume 5, Number 5, 1986; for the functionally similar read across substance, Glyceryl monooleate [CAS: 111-03-5].In a single insult occlusive patch test, 0.5 ml Glyceryl Oleate 50% in corn oil was applied to the clipped dorsal skin of 9 rabbits. Sites were graded for erythema and edema 2 and 24 h after exposure (maximum score for either erythema or edema = 4). The Primary Irritation Index after 2, 24 hours of exposure was 0.33.
Hence, Glyceryl oleate was considered to be practically not irritating to rabbit skin.
Based on the available data for the target as well as it read across substances,it can be concluded that Propylene Glycol Monooleate was not irritating to skin.Comparing the above annotations with the criteria of CLP regulation, test chemical can be classified under the category “Not Classified”.
Eye Irritation:
In different studies,Propylene Glycol Mono oleatehas been investigated for potential for ocular irritation to a greater or lesser extent. The studies are based on in vivo experiments in rabbits along with predicted data for target chemicalPropylene Glycol Mono oleateand its functionally similar read across substances, Isopropyl Myristate [CAS: 110-27-0] and Glyceryl monooleate [CAS: 111-03 -5]. The predicted data using the OECD QSAR toolbox has also been compared with the experimental data.
In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the ocular irritation potential was estimated for Propylene Glycol Monooleate. Propylene Glycol Monooleate was estimated to be not irritating to eyes of Himalayan rabbits.
The above results are also supported by the experimental study summarized in JOURNAL OF THE AMERICAN COLLEGE OF TOXICOLOGY; Volume 1, Number 4, 1982; for the functionally similar read across substance, Isopropyl Myristate [CAS: 110-27-0].100% Isopropyl myristate was instilled into the eyes of 3 rabbits. The eyes were treated daily for 3 consecutive days. The eyes were scored for signs of irritation at 24, 48 and 72 hours. The Draize scores after 24, 48 and 72 hours were 0.0 respectively.
Hence, Isopropyl Myristate was considered to be not irritating to rabbit eyes.
These results are further supported by the experimental study summarized in JOURNAL OF THE AMERICAN COLLEGE OF TOXICOLOGY; Volume 5, Number 5, 1986; for the functionally similar read across substance, Glyceryl monooleate [CAS: 111-03-5].0.1ml volume of a sunscreen formulation containing5%Glyceryl Oleate was instilled into the eyes of 6 New Zealand White rabbits. The ocular reactions were scored according to Draize method.Scoring was performed 1 h after treatment and on Days1,2, 3, and 7.
Slight conjunctivitis was observed after1h, clearing within 24 h, and no signs of irritation to other tissues were noted. Hence, Glyceryl oleate was considered to be practically not irritating to rabbit eyes.
Based on the available data for the target as well as it read across substances;and applying the weight of evidence approach, it can be concluded that Propylene Glycol Monooleate was not irritating to eyes.Comparing the above annotations with the criteria of CLP regulation, test chemical can be classified under the category “Not Classified”.
Justification for classification or non-classification
Based on the available information,Propylene Glycol Monooleate is not likely to cause any irritation to eyes and skin. Hence, Propylene Glycol Monooleate can be classified under the category “Not Classified” as per CLP regulation.
