- REPORTING FORMAT FOR THE CATEGORY APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
The category of alkyl lactates mainly contain data on propanoic acid, 2-hydroxy, C12-C16 (even and odd numbered) alkyl esters.
2. SOURCE AND TARGET CHEMICALS
Both the target and the analogues are produced by esterification of alcohols and lactate.
3. ANALOGUE APPROACH JUSTIFICATION
Since there is a significant relation between the analogues measured and the target substance, which only differs in chain length of the alcohol, read-across is here justified.

- Interpretation of results:
- moderately irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Installation of 0.1 ml of the test material into the right eye of three rabbits produced a moderate irritation involving only the conjunctivae. On the seventh day of observation these eyes were normal showing full reversibility. The observed irritation may well have been due to the presence of the C12-15 alcohols.
- Executive summary:
CERAPHYL® 41 was mildly irritating to the eyes of rabbits.
Three albino rabbits received a single application of CERAPHYL® 41 (0.1 ml) into the conjunctival sac of one eye. The contralateral eye, remaining untreated, served as a control. The eyes were examined and scored for effects on the cornea, iris and conjunctiva on Days 1, 2, 3, 4 and 7 after treatment. No corneal opacity or iritis was observed. Conjunctival irritation, noted in all the eyes,
cleared by Day 7.
