Additional information
Skin irritation
Skin irritation property of 6-chlorohexan-2-one is predicted using QSAR toolbox version 3.3.
The substance 6-chlorohexan-2-one is estimated to be irritating in an in vitro test on reconstituted human epidermis.
In other study by (Moreno, O. M., 1988) with similar substance (821-55-6) was assessed in rabbit.In skin irritation study, for2-nonanone the undiluted material produced irritant effects and scaly skin at necropsy in rabbits patch-tested for 24 hr under occlusion at 5000mg/kg.Therefore 2-nonanone was considered to be a skin irritant.
In other study by (Food and Cosmetics Toxicology, 1975) with similar substance (111-13-7) was assessed in rabbit.Skin irritation study was performed to rabbits with a dose concentration of 500mg test substance which wasapplied at full strength to intact or abraded rabbit skin for 24 hr under occlusion. The test substance was found to be slightly irritating.
On the basis of available information for the target as well as read across substance and applying weight of evidence approach, the test substance can be considered as not irritating to the skin.
Eye irritation:
Eye irritation property of 6-chlorohexan-2-one is predicted using QSAR toolbox version 3.3.
The substance 6-chlorohexan-2-one is estimated to be irritating in an in vitro test on Reconstituted Human Corneal model.
Studies on similar substance (111-13-7) from HSDB, 2006 and GESTIS,2011, eye irritation was observed.
Rats exposed to calculated vapor concentrations of 2 octanone, 8.9 mg/L (1673 ppm) for 6 hr exhibited signs of mild eye irritation.
Hence, 2- octanone was mildly irritating to rat eyesThe eye irritation potential of the undiluted liquid [2 octanone] was confirmed; in a test on rabbit eyes.Undiluted 2- octanone was slightly irritating to rabbit eyes.
Therefore, on the basis of available information for the target as well as its read across, and applying the weight of evidence approach, the test chemical6-chlorohexan-2-one was considered to be an eye irritant.
Justification for selection of skin irritation / corrosion endpoint:
The substance 6-chlorohexan-2-one is estimated to be irritating in an in vitro test on reconstituted human epidermis.
Justification for selection of eye irritation endpoint:
The substance 6-chlorohexan-2-one is estimated to be irritating in an in vitro test on Reconstituted Human Corneal model.
Effects on skin irritation/corrosion: irritating
Effects on eye irritation: irritating
Justification for classification or non-classification
On the basis of available information, the substance 6-chlorohexan-2-one is estimated to be irritating to skin and eye. It is thus classified as Category 2 skin and eye irritant.
