Description of key information
Various literature data were available in rats for the irritation/corrosion potential of long chain alcohols (LCOH C14, C16, C18 chains), alkyl sulfates (AS C12 chain representing worst case situation for C14-C20) and sodium sulfate.
C14 LCHO and C12-Alkylsulfate, covering 2.4% of the registered substance, are classified Skin irritant CLP Category 2. LCOH16 and 18 and sodium sulfate, covering >85% of the registered substance, are not classified skin irritating or corrosive. Based on the generic concentration limits (CLP, 2008), the sum of the irritating ingredients is <10%, therefore the registered substance is not classified for skin irritation or corrosion.
C14 LCHO, covering 2.4% of the registered substance, is classified Eye irritant CLP Category 2, which is under the limit concentration of 10% for non-classification. LCOH16 and 18 and sodium sulfate, covering >85% of the registered substance, are not classified skin irritating or corrosive. Based on the generic concentration limits (CLP, 2008), the sum of the irritating/corrosive ingredients is <3%, therefore the registered substance is not classified for eye irritation or damage.

- Conclusions:
- Sodium dodecyl sulfate was highly corrosive for the eyes in this in vivo test in rabbits.
- Executive summary:
The IUCLID dataset of C12-Alkylsulfate (CAS 151-21-3) in the OECD SIDS Initial Assessment Profile on Sodium dodecyl sulfate (SDS) describes the following Klimisch 1 study according to OECD Guideline 405.
0.1 mL of the test material was applied in the eyes of 4 male Kleinrusse Chbb:HM rabbits as a solution in water at a concentration 25% of active substance. The eyes were not rinsed.
Observations were made until 21 days post application. Scoring system of Draize was used.
Based on the description of the lesions and the non-reversibility of the effects over the 21 days observation period it is considered that C12-Alkylsulfate (SDS) is highly corrosive for the eyes.

- Irritant / corrosive response data:
- Diffuse corneal opacity was noted in 2 treated eyes at the 24, 48, and 72 hour observations. Iridial inflammation was noted in 2 treated eyes at the 24 hour observation and persisted in 1 treated eye at the 48 and 72 hour observations. Moderate conjunctival irritation was noted in all treated eyes 1 hour after treatment and persisted in 2 treated eyes at the 24 and 48 hour observations. Minimal conjunctival irritation was noted in 1 treated eye at the 24 and 48 hour observations and in 2 treated eyes at the 72 hour and 7 day observation.
All corneal and iridial scores and scores for conjunctival chemosis were normal by day 7. Conjunctival redness persisted in 2 rabbits through day 7 but scores were 0 by day 14. The effects were therefore fully reversible.
Discharge was observed from all treated eyes 1 hour after instillation and persisted in one eye for 48 hours and in another for 72 hours. All eyes were clear at 7 days. - Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- Kalcol 4098 applied as a powder is classified as category 2 eye irritant according to GHS criteria based on corneal opacity of >= 1 in 2 test animals and persistence beyond 7 days. Effects were fully reversible by day 14.
- Executive summary:
The IUCLID dataset of 1-Tetradecanol (CAS 112-72-1, Tradename Kalcol 4098) in the OECD SIDS Initial Assessment Profile Long Chain Alcohols describes the following Klimisch 1 study according to OECD TG 405 in 3 New Zealand White rabbits.
The test material was solid and was ground to a fine powder prior to instillation and 0.1 mL( ca 46mg) was applied in the eye using an adapted syringe. No rinsing was performed.
Observations were made until 14 days post application. Scoring system of Draize and modified scoring system of Kay and Calandra were used.
Diffuse corneal opacity was noted in 2 treated eyes at the 24, 48, and 72 hour observations. Iridial inflammation was noted in 2 treated eyes at the 24 hour observation and persisted in 1 treated eye at the 48 and 72 hour observations. Moderate conjunctival irritation was noted in all treated eyes 1 hour after treatment and persisted in 2 treated eyes at the 24 and 48 hour observations. Minimal conjunctival irritation was noted in 1 treated eye at the 24 and 48 hour observations and in 2 treated eyes at the 72 hour and 7 day observation.
Kalcol 4098 applied as a powder is not classifiable as an eye irritant according to EU criteria. Kalcol 4098 is however a category 2A eye irritant according to GHS criteria based on corneal opacity of >= 1 in 2 test animals and persistence beyond 7 days. Effects were fully reversible by day 14.

- Executive summary:
The IUCLID dataset of 1-Tetradecanol (CAS 112-72-1, Tradename Alfol 14 ) in the OECD SIDS Initial Assessment Profile Long Chain Alcohols describes the following Klimisch 2 study according to contract laboratory protocol in 6 New Zealand White rabbits.
The test material was applied in the eye as a solid at a dose of 100 mg. The treated eyes were rinsed after 24 hours to remove residual test material. The other eyes served as control. Observations were made until 72 hours post application. Scoring system of FDA 1965 was used. Although individual animal data was provided, only the converted scores were reported, so it is not possible to present the data according to EC/GHS criteria.
The average score (includes all end points) for each time point was as follows:
1 hour: 6.7
24 hours: 18
48 hours: 12.5
72 hours: 6
The following lesions were observed:
Cornea: opacity slight to easily discernible involving 1/4 to 3/4 of the corneal surface observed in all animals. At 72 hours there was no corneal involvement in any animal.
Iris: barely perceptible to minimal iritis (grade 1) in 1/6 rabbits at 24 hours after instillation. No iritis at 48 or 72 hours.
Conjunctivae (Redness): Slight to moderate conjunctivitis in all eyes from 24 hours. At 72 hours there was minimal to slight redness in 6/6.
Conjunctivae (Chemosis): Minimal to pronounced chemosis of the eye lids with a slight watery-mucoid discharge in all animals. At 72 hours barely perceptible to moderate chemosis 4/6 and slight discharge 2/6.
Based on the description of the lesions and the consistent reduction of severity of the effects over the 72 hours observation period it is considered that Alfol 14 is not classifiable as an eye irritant according to EU or GHS criteria.

- Executive summary:
The IUCLID dataset of Na2SO4 (CAS 7757 -82 -6) in the OECD SIDS INITIAL ASSESSMENT PROFILE of Sodium sulfate describes the following Klimisch 1 study according to OECD Guideline 405.
Eye irritation was tested in 3 HC:NZW rabbits. 90 mg of test material was instilled in the conjunctival sac of the eye for 24 hours exposure. Observations were made until 21 days post application. Scoring system of Draize was used. The positive effects were primarily based on the conjunctivae (redness) observed in the test. The effects were reversible within 7 days. Sodium sulfate appears to be slightly irritating to the eye in rabbit.

Additional information
No extra testing was performed as literature data were available as weight-of-evidence/supporting data for the various components of the registered substances. A selection of most reliable sources (Klimisch 1-2) was made.In vitro testing was waived as adequate data from in vivo studies was available.
Skin irritation/corrosion:
- Various literature data were available in rabbits after application of 0.5 g on the skin and in humans after patch testing for the long chain alcohols (LCHO) with chain length between C14 and C18, as summarised below.
- For LCOH 14 (Alfol 14; 1-Tetradecanol;CAS 112-72-1) erythema and oedema scores were >2.3 in 5/6 rabbits while the group mean 24+48+72 hour > 2.3 (2.46) (SIDS, 2006; Scientific Associates, Inc. 1977), however no irritation was observed in human volunteers by patch testing (SIDS, 2006; Henkel 1996). - For LCOH 16 (1-Hexadecanol; CAS 36653-82-4) all erythema and oedema scores at 24, 48 and 72 hours in rabbits were 0 and primary dermal irritation index was 0 (SIDS, 2006; Sanders, 1996b).
- For LCOH 18 (1-Octadecanol; CAS 112-925) all erythema and oedema scores at 24, 48 and 72 hours in rabbits were 0 and primary dermal irritation index was 0 (SIDS, 2006; Sanders, 1996c). For thealkyl sulfates (AS), there were no data for the C14-C20 chain lengths, however literature data were available for the C12 chain length after application of 0.5 g on the rabbit skin. The C12 AS can be considered as a worst case substance.
- For C12-Alkylsulfate (CAS 151-21-3) there were lesions and due the non-reversibility of the effects over the 21 days observation period it is considered that C12-Alkylsulfate is skin irritating (SIDS, 2007; Henkel, 1987).
For the sodium sulfate, literature data were available:
- For Sodium sulfate (CAS 7757 -82 -6) skin irritation was tested in 3 rabbits did not result in observations up to 14 days post application (SIDS 2005; Bayer, 1991). Eye irritation/corrosion: Various literature data were available in rabbits after instillation of 0.1 g in the eye for the long chain alcohols (LCHO) with chain length between C14 and C20, as summarised below.
- For LCOH 14 (Alfol 14; 1-Tetradecanol;CAS 112-72-1) corneal opacity of>1 was observed in 2 rabbits, persisting beyond 7 days and fully reversible by day 14 (SIDS, 2006; Sanders, 1996f), however when instilled into the rabbit eye as a 10% solution in polyethylene glycol 400, no irritation was observed (SIDS, 2006; Hempstock 1997b). A supporting study in rabbits, reduction of severity of the effects was observed over the 72 hours observation, however scores do not comply with GHS and cannot be used for classification (SIDS, 2006; Scientific Associates, Inc. 1977b).
- For LCOH 16 (1-Hexadecanol; CAS 36653-82-4) moderate conjunctival irritation was noted in all eyes at 1 hour which reduced to minimal conjunctival irritation at 24 hours; all eyes were normal at 48 and 72 hours post instillation (SIDS, 2006; Sanders, 1996g).
- For LCOH 18 (1-Octadecanol; CAS 112-925) iridial inflammation was noted in 2 eyes at 1 hour and 1 eye at 24 hours. Minimal to moderate conjunctival irritation was reported at 1 hour with minimal conjunctivitis in 2 eyes at 24 hours. All eyes scored 0 at 48 and 72 hours post instillation (SIDS, 2006; Sanders, 1996h).
For the alkyl sulfates, there were no data for the C14-C20 chain lengths, however literature data were available for the C12 chain length after instillation of 0.1 g in the rabbit eye:
- For C12-Alkylsulfate (CAS 151-21-3) a concentration of 25% resulted in eye lesions within 1 hour that were non-reversible and corrosive for the eyes (SIDS, 2007; Henkel, 1987). For the sodium sulfate, literature data were available: - For Sodium sulfate (CAS 7757 -82 -6) skin irritation was tested in 3 rabbits did not result in observations up to 14 days post application (SIDS 2005; Bayer, 1991).
- Conclusion: C14 LCHO and C12-Alkylsulfate, covering 2.4% of the registered substance, are classified Skin irritant CLP Category 2. LCOH16 and 18 and sodium sulfate, covering 88% of the registered substance, are not classified skin irritating or corrosive. Based on the generic concentration limits (CLP, 2008), the sum of the irritating ingredients is <10%, therefore the registered substance is not classified for skin irritation or corrosion. C14 LCHO, covering 2.4% of the registered substance, is classified Eye irritant CLP Category 2, limit concentration of 10% for non-classification.C12-Alkylsulfate 25% covering 0% of the registered substance, is Eye corrosive CLP Category 1. LCOH16 and 18 and sodium sulfate, covering 88% of the registered substance, are not classified skin irritating or corrosive. Based on the generic concentration limits (CLP, 2008), the sum of the irritating/corrosive ingredients is <3%, therefore the registered substance is not classified for eye irritation or damage.
Justification for classification or non-classification
Based on these results and according to CLP (No. 1272/2008 of 16 December 2008), the registered substance does not have to be classified and has no obligatory labelling requirement for skin and eye irritation/corrosion.
