Description of key information
-The acute eye irritation study ((Henkel KGaA. 1980) indicates that Alcohols, C12-14 was not irritating.
Result: not irritating to eye. Based on the Draize scores reported it is considered that Alcohols, C12-14 is not not an eye irritant according to either EU or GHS criteria.. C12-14 alcohol is not irritating to the eye when applied undiluted.
- The results of the study (Henkel KGaA. 1980) indicate that Alcohols, C12-14 is irritant to skin. Alcohols, C12-14 is a skin irritant according to EU criteria based on a group 24+48+72 hour mean score for erythema of 2. According to GHS criteria the test substance is mild irritant (class 3) with all individual 24+48=72 hour erythema scores between 1.7 - 2.3 (only 2/6 gave a reading of 2.3) following a 24 hour occluded application to rabbit skin.
- Respiratory irritation
There is no information available from single or repeated inhalation exposures in laboratory animals or from human experience allowing a conclusion on potential respiratory tract irritation of the aliphatic alcohols.

- Irritant / corrosive response data:
- The numerical values corresponding to each animal, tissue and observation time were recorded. The data relating to the conjunctivae were designated by the letters A (redness), B (chemosis) and C (discharge), those relating to the iris designated by the letter D and those relating to the cornea by the letter E (degree of opacity) and F (area of opacity). For each tissue the score was calculated as follows:
Score for the conjunctivae - (A+B+C)x2
Score for iris - Dx5
Score for cornea - (ExF)x5
Using the numerical data obtained a modified version of the system described by Kay J H and Calandra J C, J.Soc.Cosmet Chem., 1962 13 281-289 wasused to classify the ocular irritancy potential of the test material. This was achieved by adding together the scores for the cornea, iris and conjunctivae for each time point for each rabbit. The group means of the total scores for each observation were calculated. If any rabbit shows irreversible oculardamage the test material will be classified as corrosive to the eye.
Overall irritation score: Maximum group mean score 15.3 at 1 hour post instillation. Classified as a mild irritant according to a modified Kay and
Calandra system. - Other effects:
- DESCRIPTION OF LESIONS: Dulling of the cornea noted in 2 animals 1 hour after instillation, diffuse corneal opacity noted in 1 rabbit at 24 hours
post instillation. Iridial inflammation noted in 2 animals at 1 hour post instillation only. Moderate conjunctival irritation noted in all eyes at 1 hour
which reduced to minimal conjunctival irritation at 24 hours.
REVERSIBILITY: All eyes were normal at 48 and 72 hours post instillation.
OTHER EFFECTS: Residual test material noted around the treated eyes at 1 hour post instillation. - Interpretation of results:
- other: not irritating
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- Kalcol 6098 (Hexadecan-1-ol (C16))is not an eye irritant according to EU or GHS criteria.Classification: not irritating.
-Hexadecan-1-ol (C16) is supporting substance for Alcohols,C12-C14 and the one of the component in Alcohols,C12-C14 .

Additional information
Eye irritation
-The acute eye irritation study ((Henkel KGaA. 1980) indicates that Alcohols, C12-14 was not irritating.
Result: not irritating to eye. Based on the Draize scores reported it is considered that Alcohols, C12-14 is not not an eye irritant according to either EU or GHS criteria.. C12-14 alcohol is not irritating to the eye when applied undiluted.
The eye irritation potential for alcohols with a chain length of C12 and above has been shown to be minimal.
Result: not irritating.
Kalcol 2098 (Dodecan-1-ol (C12)) is not irritating to the rabbit eye using either EU or GHS criteria. Classification: not irritating
Dodecan-1-ol (C12) is supporting substance for Alcohols,C12-C14 and the main component.
Based on the descriptions of the lesions it is considered that Alcohols, C12-14 is not irritating to eye according to EU criteria or GHS criteria.
Skin irritation
Linear Alcohols.The data demonstrate that lower members of the linear alcohols (C6 – C11) have a skin irritancy potential ranging from mild to irritant, when applied undiluted for 4 – 24 hours. Application of diluted materials resulted in a lower grade irritation. The skin irritation potential of linear alcohols in the range C12 and C16 is graded as mild - essentially non-irritant. Alcohols with a carbon chain length C18 and above were generally without evidence of a skin irritation potential.
Conclusion:Aliphatic alcohols in the range C6 – C11 are mild irritants, not anticipated to be corrosive.
Aliphatic alcohols in the range C12 – C16 have a low degree of skin irritation potential; alcohols with chain lengths of C18 and above are non-irritant to skin.
-The results of the study (Henkel KGaA. 1980) indicate that Alcohols, C12-14 is irritant to skin. Alcohols, C12-14 is a skin irritant according to EU criteria based on a group 24+48+72 hour mean score for erythema of 2. According to GHS criteria the test substance is mild irritant (class 3) with all individual 24+48=72 hour erythema scores between 1.7 - 2.3 (only 2/6 gave a reading of 2.3) following a 24 hour occluded application to rabbit skin.
Result: irritating.
Based on the descriptions of the lesions it is considered that Alcohols, C12-14 is irritating to skin according to EU criteria and
mild irritant (class 3) according to GHS criteria
Respiratory irritation.
There is no information available from single or repeated inhalation exposures in laboratory animals or from human experience allowing a conclusion on potential respiratory tract irritation of the aliphatic alcohols.
Justification for selection of skin irritation / corrosion
endpoint:
Alcohols, C12-14 is a skin irritant according to EU criteria based
on a group 24+48+72 hour mean score for erythema of 2.
According to GHS criteria the test substance is mild irritant (class 3)
with all individual 24+48=72 hour erythema scores between 1.7 - 2.3
(only 2/6 gave a reading of 2.3) following a 24 hour occluded
application to rabbit skin.
Justification for selection of eye irritation endpoint:
The C12-14 alcohol is not irritating to the eye when applied
undiluted.
Result: not irritating .
Effects on skin irritation/corrosion: irritating
Justification for classification or non-classification
Based on the hazard assessment of Alcohols, C12-14 in section 2.1 and 2.2. in IUCLID 6., available data for the substance and following the “Guidance on Information Requirement and Chemical Safety Assessment R.8. Characterisation of dose [concentration]- response for human health”, according to the EU’s list of dangerous substances (OJEC No L200/130.7.99)and according to the criteria described in Directive 67/548 and in the CLP Regulation:
Directive 67/548 |
Skin Corrosivity C R35 Causes severe burns R34 Causes burns Skin Irritation Xi R38 Irritating to skin R43 May cause sensitization by skin contact Eye Irritation (Ocular Lesions) Xi R36 Irritating to eyes R37 irritating to respiratory system R41 Risk of serious damage to eyes |
