- Conclusions:
- It was concluded that the test material with a mean tissue viability of 10.9 % ± 3.4, is predicted as a skin irritant.
- Executive summary:
The objective of the test was to assess the skin irritancy, in vitro, of the test substance.
The test material was applied to EPISKIN human epidermis skin constructs. The constructs consisted of normal, human-derived epidermal keratinocytes, which had been cultured to form a multilayered, highly differentiated model of the human epidermis with a functional multilayered stratum corneum. The cell viability of the multi layers was determined by mitochondrial dehydrogenase activity. The prediction model uses the percentage viability values (compared to negative control viability) to identify irritant and non-irritant materials.
The test material elicited a mean tissue viability of 10.9 ±3.4 % and was predicted as irritant.

- Negative control:
The mean absorbance of the triplicate negative control values was 0.618 which was above the minimum acceptance value of 0.6. The standard deviation of the % viability was 2.8 which was below the maximum acceptance value of 18.
- Positive control: The mean viability of the positive control was 12.5% ± 6.0 of the negative control. These were below the maximum acceptance values of 30% viability and SD of 18.
There was no colour change in the test substance, 2-Propylheptan-l-ol (MTT) solution or the water control (MTT) solution after three hours incubation in the dark at 37 ±2°C in a humidified atmosphere of5% CO2 in air. The test substance had not interacted with the MTT.
Sample | Tissue viability as percentage of mean OD negative control | ||||
Replicate Tissues | Mean +/- SD | Prediction MTT endpoint | |||
Negative Control | 102.7 | 100.2 | 97.1 | 100.0 +/- 2.8 | not applicable |
Positive control | 7.7 | 19.3 | 10.4 | 12.5 +/- 6.0 | irritant |
2-Propylheptan-I-ol | 14.7 | 8.1 | 9.9 | 10.9 +/- 3.4 | irritant |
The Standard Operating Procedure, In Vitro Skin Irritation Test: Human Epidermis Model EPISKIN, EPISKIN Skin Irritation Test-42hours (L'Oreal 2005) recommends analysis of IL-1alpha if the MTT mean tissue viability of the test material is >/= 50%. As the mean tissue viability of test material, 2-Propylheptan-1-ol, was 10.9 % ± 3.4, IL-1 alpha analysis of the medium was not required.

Additional information
skin:
In a GLP in vitro EPISKIN Skin Irritation Test (Val. 2, Evonik Oxeno GmbH, 2009) the test substance was classified as irritant potential.
The skin irritating potential is confirmed by an in vivo skin irritation/corrosion study (TSCAT, OTS 0538594, Doc I.D. 88-920007511, Monsanto Company, 1979). 0.5 ml of the undiluted test substance was administered to the skin of 6 New Zealand Albino rabbits for 24 h (according to Federal Hazardous Substance Act). The mean scores (24 - 48 -72 h) for erythema and edema were 3.78 and 3.39, respectively. All observed edema and erythema were reversible within 7 days. Additionally, a severe defatting effect was observed. This study was conducted before the implementation of GLP and OECD Guidelines.
eye:
Irritation to eyes was analyzed in a study reliable with restrictions (TSCAT, OTS 0538594, Doc I.D. 88-920007511, Monsanto Company, 1979). Six albino rabbits received a single instillation of 0.1 ml of the undiluted test substance for 24 h. The Mean Overall Irritation Score (24-48-72 h) was 16.3 (max. score: 110) and the test substance was classified as a mild eye irritant (according to Federal Hazardous Substance Act) as all effects were fully reversible within 7 days.
In an additional study, eye injury in New Zealand White rabbits was recorded in a 10-grade ordinal series and was based upon the degree of corneal necrosis that results from installation of 2-Propylheptan-1-ol into the eyes of the rabbits. The administration of the test substance resulted in a grade 2 corneal injury on a scale of 1-10. These results indicate that the test substance caused minimal corneal injury (Smyth, H.F., 1962; Val.2).
Both studies were conducted before the implementation of GLP and OECD Guidelines.
In a GLP-conform BCOP-Test conducted similar to OECD 437 the test substance was negative.
