- Conclusions:
- The in vitro skin irritation test was conducted according to OECD 439 guideline and GLP principles.
It is concluded that this test is valid and that Licocare RBW 106 is non-irritant in the in vitro skin irritation test. - Executive summary:
Skin irritation is expressed as the remaining cell viability after exposure to the test substance. The relative mean tissue viability obtained after 15 minutes treatment with Licocare RBW 106 compared to the negative control tissues was 72%. Since the mean relative tissue viability for Licocare RBW 106 was above 50% after 15 minutes treatment it is considered to be non-irritant.
The positive control had a mean cell viability of 8% after 15 minutes exposure. The absolute mean OD570of the negative control tissues was within the laboratory historical control data range. The standard deviation value of the percentage viability of three tissues treated identically was less than 7%, indicating that the test system functioned properly.

- Conclusions:
- Based on the results of the experiment, it is concluded that single dermal application of Licocare RBW 106 TP did not reveal any skin reactions when applied to the skin of New Zealand White Rabbits, hence the test item is considered as non-irritant and did not meet the classification criteria according to the Globally Harmonized System (GHS) of Classification and Labelling of Chemicals
- Executive summary:
The test item, Licocare RBW 106 TPwas evaluated forAcute Dermal Irritation/Corrosion in New Zealand White rabbits as per OECD Guidelines for Testing of Chemicals No. 404 (Section 4: Health Effects), “Acute Dermal Irritation/Corrosion” adopted on 28 July 2015.
The study was performed in two phases i.e. initial test and confirmatory test. Approximately 24 hours before the application of the test item, fur on the dorso-lateral area of the trunk of the animals was removed by clipping closely using an electric hair clipper (approximately 8 × 12 cm). Care was taken to avoid abrasion to the skin and the animals with healthy intact skin were used for experiment.
As there was no information on the test item, in initial test, three patches were applied for 3 minutes, 1 hour and 4 hour exposure period. The application site 1 (anterior left trunk region) of the animal was served as untreated control. On application site 2 (posterior left trunk region), site 3 (posterior right trunk region) and site 4 (anterior right trunk region) of the animal, 0.5 g oftest item moistened with 1.0 mL of distilled water was applied for 3 minutes, 1 hour and 4 hours respectively (semi-occlusive dressing). The first test patch was applied on site 2 and removed after three minutes. No skin reaction was observed after immediate observation, a second test patch was applied at site 3 and removed after one hour. After immediate observation, the observations at this stage indicated that exposure could be humanely allowed to extend to four hours, a third test patch was applied at site 4 and removed after four hours, and the response was graded. The application site 1 (anterior left trunk region) of the animal was covered with blank cotton gauze at the time of site 4 application and was removed along with application site 4. After removal of the test patches, the application sites were washed with distilled water and dried with absorbent cotton without altering the existing response or the integrity of the epidermis. The application sites 1, 2, 3 and 4 were scored immediately after patch removal whereas the application sites 1 and 4 were also scored approximately at 1, 24, 48 and 72 hours after the patch removal.
As there was no corrosive effects observed during initial test, the confirmatory test was performed using two additional rabbits. In the confirmatory test, the patches were applied for 4 hours exposure period. Each animal had two application sites. The clipped area of skin at left trunk region and right trunk region were identified as application sites 1 and 2 respectively.
In the confirmatory test, the application site 1 (left trunk region) of each animal was served as untreated control covered with blank cotton gauze. On application site 2 (right trunk region) of each animal, 0.5 g oftest item moistened with 1.0 mL of distilled water was applied for 4 hours exposure period and removed after 4 hours. After removal of the test patches, the application sites were washed with distilled water and dried with absorbent cotton without altering the existing response or the integrity of the epidermis. The application sites 1 and 2 were scored approximately at 1, 24, 48 and 72 hours after patch removal.
The mean score across 3 scoring times (24, 48 and 72 hours after patch removal) for both initial test animal and confirmatory test animals was ‘0’ for erythema and oedema grades.
No erythema and oedema was observed at the test item application site in both initial and confirmatory test animals.
All the animals were observed once daily for clinical signs of toxicity and twice daily for mortality during the observation period. No clinical signs of toxicity and mortality was observed in both initial and confirmatory test animals.
Body weight was recorded on the day of receipt and prior to application of test item (day 1) and at termination. No changes were observed in body weight andpercent change in body weight with respect to day 1in both initial and confirmatory test animals. All the animals revealednormal increase in the body weightduring the observation period.
At termination, all the animals were sacrificed by intravenous administration of sodium thiopentone. Nogross pathological findings were observed in any of the animals in both initial and confirmatory test

- Conclusions:
- Since Licocare RBW 106 induced an IVIS ≤ 3, no classification is required for eye irritation or serious eye damage.
- Executive summary:
The negative control responses for opacity and permeability were less than the upper limits of the laboratory historical range indicating that the negative control did not induce irritancy on the corneas.The mean in vitro irritancy score of the positive control (20% (w/v) Imidazole) was 150 and within two standard deviations of the current historical positive control mean. It was therefore concluded that the test conditions were adequate and that the test system functioned properly.
Licocare RBW 106 did not induce ocular irritation through both endpoints, resulting in a meanin vitroirritancy score of 2.8 after 240 minutes of treatment.

- GHS criteria not met
- Conclusions:
- Based on the above results of the experiment and under the experimental conditions employed, it is concluded that the test item Licocare RBW 106 TP was “non-irritant” to the rabbit eye following single ocular instillation. Hence, the test item is unclassified as per the Globally Harmonized System of Classification and Labelling of Chemicals (GHS)
- Executive summary:
The test item,Licocare RBW 106 TPwas evaluated for Acute Eye Irritation/Corrosion in New Zealand White Rabbitsas perOECD 405 (Section 4: Health Effects), “Acute Eye Irritation/Corrosion” adopted on 09 October 2017.The study was performed in two phases i.e., initial and confirmatory tests. Both the eyes of each experimental animal were examined within 24 hours before the treatment. The animals with absence of signs of eye irritation, ocular defects or pre-existing corneal injury were used for the treatment. The pH of test item is 6.44 as per in-house pH determination.The initial test was conducted using single male rabbit and confirmatory test was conducted using two male rabbits. The systemic analgesic (tramadol hydrochloride injection 2.5 mg/kg) and two drops of topical ocular anaesthetic (0.5% tetracaine hydrochloride) were given to each animal sixty minutes and five minutes prior to test item instillation respectively. The 0.1 mL (Initial test: 69.50 mg and Confirmatory test: 65.93 mg and 64.02 mg) of test item was instilled into the conjunctival sac of the left eye and right eye served as control. The eyes were scored approximately at 1, 24, 48 and 72 hours. Slit lamp examination was carried out using fluorescein strips (fluorescein sodium ophthalmic strip USP) and were scored approximately at 24 hours for both initial and confirmatory test.All the animals (initial test and confirmatory test) were observed twice daily for clinical signs of toxicity and mortality. No treatment related clinical signs of toxicity and mortality were observed in all the animals (initial and confirmatory tests) after the test item instillation.In both initial and confirmatory test, treated eye (left) revealed ocular lesions like redness at 1 hour observation. The observed lesion reversed back to normal by 24 hour observation.In both initial and confirmatory test, no ocular lesions were observed at 24 hour observation during slit lamp examination.The body weight was recorded on the day of receipt, on the day of treatment (prior to instillation of test item) and on the day of termination of the experiment. No changes were noted in body weight and percent change in body weight with respect to day 1 in both initial and confirmatory test. All the animals revealed physiologically normal increase in body weight in both initial and confirmatory tests.All the animals were sacrificed by intravenous administration of sodium thiopentone and observed for gross pathological changes. Nogross pathological findings were observed in all the animals.
For initial test and confirmatory test, the mean score calculated across 3 scoring times (approximately 24, 48 and 72 hours after test item
instillation) for cornea, iris and conjunctival redness and conjunctival chemosis were 0, 0, 0 and 0 respectively

The individual in vitro irritancy scores for the negative controls ranged from -0.7 to 0.5. The individual positive control in vitro irritancy scores ranged from 146 to 156. The corneas treated with the positive control were turbid after the 240 minutes of treatment.
The corneas treated with Licocare RBW 106 showed opacity values ranging from 1.8 to 3.8 and permeability values ranging from -0.008 to 0.011. The corneas were slightly translucent after the 240 minutes of treatment with Licocare RBW 106. No pH effect of the test item was observed on the rinsing medium. Hence, the in vitro irritancy scores ranged from 2.0 to 3.7 after 240 minutes of treatment with Licocare RBW 106.
