Interpretation of results:

Conclusions:

No erythema and oedema (skin irritation) were found at the end of 72 hour observation period after patch removal.
Hence, it was concluded that “Benzyl propionate (CAS No. - 122-63-4)” was Non-Irritating to the skin of Female New Zealand White rabbits under the experimental conditions tested and being classified as “Category- Not Classified” as per CLP Regulation.

Executive summary:

Acute Dermal Irritation/corrosion Study of “Benzyl propionate(CAS No. -122-63-4)”in Rabbits, was performed in a OECD GLP laboratory (Sustainability Support Services (Europe) AB has the letter of access). This study was performed as per OECD guideline No. 404.

 

Three healthy young adult female rabbits were used for conducting acute dermal irritation study.Body weights were re­corded on day 0 (prior to application) and at termination. Rabbits with good intact skin were selected for the study. The hairs of all the rabbits were clipped at contralateral sites, approximately 24 hours prior to treatment.A dose of0.5 ml of test item (as such) wasappliedto the skin,over an area of approximately 6 x 6 cm clippedof haironone side of rabbits.The other untreated side was kept as control area and 0.5 ml of distilled water was applied at this site. At the end of 4 hours, the gauze patch was removed and test item application site was wiped with water without altering the integrity of the epidermis. Initially, the test item was applied to the clipped area of skin of one rabbit. The test site was covered with gauze patch.After 4 hours of exposure in Animal No. 1, there was no erythema and oedema observed at 1, 24, 48 and 72 hours observation.Hence the confirmatory test was conducted on additional two rabbits (No. 2 and 3)to confirm the non irritant nature of the test item. In Animals No. 2 and 3 after post patch removal, revealed no erythema and oedema at 1, 24, 48 and 72 hours observation. The patch was removed after 4 hours and rabbits wereobservedfor erythema and oedemaat 1, 24, 48 and 72 hours after patch removal, evaluatedand graded as per Draize method. The individual mean score at 24, 48 and 72 hoursfor Animal Nos. 1, 2 and 3 were 0.00, 0.00, 0.00 and 0.00, 0.00, 0.00, for erythema and oedema formation, respectively.  

 

Hence, it was concluded that “Benzyl propionate (CAS No. - 122 -63-4)” was Non-Irritating to the skin of Female New Zealand White rabbits under the experimental conditions tested and Classified as “Category- Not Classified” as per CLP Regulation.

Interpretation of results:

Conclusions:

Under the experimental conditions tested, eye irritation and reversibility of effects on eyes of rabbits was observed at 72 hours.
Hence under the experimental test conditions, Benzyl propionate (CAS No. - 122-63-4) is “Non Irritant” to New Zealand White Male rabbit eyes and is being classified as “Not Classified” as per the CLP regulation.

Executive summary:

Acute Ocular Irritation/corrosion Study of “Benzyl propionate(CAS No. -122-63-4)”in Rabbits, was performed in an OECD GLP laboratory (Sustainability Support Services (Europe) AB has the letter of access). This study was performed as per OECD guideline No. 405.

.

Rabbits free from injury of eye were selected for the study. The eyes of all the rabbits were examined 24 hours prior to treatment. One eye of each rabbit served as control and other as treated. Control eye was left untreated whereas;0.1 ml of test item (as such)was instilled in the other (treated) eye of rabbits.The eye was observed at 1, 24, 48, 72 hours after test item instillation.Ophthalmoscope was used for scoring of eye lesions.

In the initial test,0.1 ml of test itemwas applied into the conjunctival sac of the right eye of Animal No.1. The left eye of the rabbit served as the control. Animal No. 1 presented ocular lesions at 1 hour observation period. Hence the confirmatory test was conducted on additional two rabbits (Animal No. 2 and 3);0.1 ml of test itemwas instilled into the conjunctival sac of right eye and left eye served as the control. Ocular lesions were observed at 1, 24 and 48 hour in Animal Number 2 whereas in Animal Number 3 ocular lesions presented only at 1 hour observation period. Untreated eye of the treated rabbits was normal throughout the experimental period of 72 hours.

The following grading scores were observed in treated eye of tested rabbits.

Observation at 1 hour after instillation of test item revealed: Cornea-No ulceration or opacity in all 3 animals; Area of Opacity-Zero in all the animals;Iris:Normal in all the animals.Conjunctivae -Some blood vessels definitely hyperaemic (injected) in all the animals;Chemosis:Some swelling above normal (includes nictating membranes) were observed in animal number 1 and 3 whereas animal number 2 was normal. Observation at 24 hours after instillation of test item revealed: Cornea-No ulceration or opacity in all the animals; Area of Opacity-Zero in all the animals;Iris:Normal in all the animals.Conjunctivae -Some blood vessels definitely hyperaemic (injected) was observed in animal no. 2. Animal no. 1 and 3 recovered to normal;Chemosis:No swelling was observed in all the Animals. At 24 hours observation the rabbits were examined for corneal epithelium cell damage using sodium fluorescein strips and noticed 0 % damage in Animal Nos 1, 2 and 3, respectively. Observation at 48 and 72 hours after instillation of test item revealed: Cornea-No ulceration or opacity in all the animals; Area of Opacity-Zero in all the animals;Iris:Normal in all the animals.Conjunctivae -Some blood vessels definitely hyperaemic (injected) was observed in animal no. 3 at 48 hours which was recovered to normal at 72 hours observation whereas blood vessels were normal in Animal Numbers 1 and 3 at 48 and 72 hours observation;Chemosis:No swelling was observed in all the animals.

The individual mean score for Animal Nos. 1, 2 and 3at 24, 48, 72 hoursfor Corneal opacity, iris, conjunctiva, chemosis were found 0.00, 0.00, 0.00, 0.00 ; 0.00, 0.00, 0.67, 0.00 and 0.00, 0.00, 0.00, 0.00, respectively. Under the experimental conditions tested, eye irritation and reversibility of effects on eyes of rabbits was observed at 72 hours. 

Hence under the experimental test conditions,Benzyl propionate (CAS No. - 122-63-4) is “Non Irritant” to New Zealand White Male rabbit eyes and is being classified as “Not Classified” as per the CLP regulation.

Endpoint conclusion

Endpoint conclusion:

no adverse effect observed (not irritating)

Additional information

Skin irritation:

In a patch test conducted on Female New Zealand White rabbits, no erythema and oedema (skin irritation) were found at the end of 72 hour observation period after patch removal.

Hence, it was concluded that Benzyl propionate (CAS No. - 122-63-4) was non-irritating to the skin of under the experimental conditions tested.

The supporting studies also indicate that the substance is not a skin irritant.

Eye Irritation:

Under the experimental conditions tested, eye irritation and reversibility of effects on eyes of rabbits was observed at 72 hours. Hence under the experimental test conditions, Benzyl propionate (CAS No. - 122-63-4) is “non irritant” to New Zealand White Male rabbit eyes.

Justification for selection of skin irritation / corrosion endpoint:

No erythema and oedema (skin irritation) were found at the end of 72 hour observation period after patch removal.

Hence, it was concluded that “Benzyl propionate (CAS No. - 122-63-4)” was Non-Irritating to the skin of Female New Zealand White rabbits under the experimental conditions tested and being classified as “Category-Unclassified” as per CLP Regulation.

Justification for selection of eye irritation endpoint:

Under the experimental conditions tested, eye irritation and reversibility of effects on eyes of rabbits was observed at 72 hours.  

Hence under the experimental test conditions, Benzyl propionate (CAS No. - 122-63-4) is “Non Irritant” to New Zealand White Male rabbit eyes and is being classified as “Unclassified” as per the CLP regulation.

Justification for classification or non-classification

The available studies indicate that the test substance, benzyl propionate is non irritating to skin and eye and hence is being classified as 'Non irritant' as per the CLP classification.
