Conclusions:
Based upon the referred classification criteria (Commission Directive 2001/59/EC of August 2001), FP-100 is considered to be “not irritating” to rabbit skin.
Executive summary:

The primary skin irritation potential of FP-100 was investigated according to OECD test guideline no. 404. The test item was applied by topical semi-occlusive application of 0.5 g to the intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours after removal of the dressing.

 

The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0.

 

The test item caused no staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed.

Based upon the referred classification criteria (Commission Directive 2001/59/EC of August 2001), FP-100 is considered to be “not irritating” to rabbit skin.

Irritant / corrosive response data:
Reversibility of any observed effect: Changes fully reversible within 2 days
Not Irritating - IRRITATION: The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity and iris were 0.00 for all three animals. The individual mean scores for the conjunctivae were 0.00, 0.00 and 0.33 for reddening and 0.00 for chemosis for each of the three animals.

No abnormal findings were observed in the cornea or iris of any animal at any of the measurement intervals.

A slight reddening of the conjunctivae was noted in the three animals 1 hour after installation which persisted in one female up to the 24-hour reading. Additionally, all animals expressed a slight reddening of the sclerae at the 1-hour observation, only. White test item remnants were present in all treated animals one hour after installation.
Other effects:
The installation of FP-100 into the eye resulted in mild,
early-onset and transient ocular changes, such as reddening
of the conjuctivae and sclerae. These effects were
reversible and were no longer evident 48 hours to 72 hours
after treatment.

VIABILITY/MORTALITY AND CLINICAL SIGNS: No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred.

COLORATION: No staining of the treated eyes produced by the test item was observed.

CORROSION: No corrosion of the cornea was observed at any of the reading times.

BODY WEIGHTS: The body weights of all rabbits were considered to be within the normal range of variability.

Animal No. Sex Last Day of Observation
91 male 2721g
92 female 2573g
93 female 2830g

No statistical analysis was performed

 

NECROPSY: No necropsy was performed on the animals sacrificed at termination of observation. The surviving animals were killed by intravenous injection of Pentobarbitone into the ear vein at a dose of at least 1 mL/kg body weight and discarded.

Interpretation of results:
other: not classified
Remarks:
Criteria used for interpretation of results: OECD GHS
Conclusions:
Based upon the referred classification (Commission Directive 2001/591EC of August 06, 2001), FP-100 is considered to be “not irritating” to the rabbit eye.
Executive summary:

The primary eye irritation potential of FP-100 was investigated according to OECD test guideline no. 405. The test item was applied by instillation of 0.1 g into the left eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test item instillation.

 

The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity and iris were 0.00 for all three animals. The individual mean scores for the conjunctivae were 0.00, 0.00 and 0.33 for reddening and 0.00 for chemosis for each of the three animals.

 

The instillation of FP-100 into the eye resulted in mild, early-onset and transient ocular changes, such as reddening of the conjunctivae and sclerae. These effects were reversible and were no longer evident 48 to 72 hours after treatment, the end of the observation period for all animals. No abnormal findings were observed in the cornea or iris of any animal at any of the examinations. No corrosion was observed at any of the measuring intervals. No staining of the treated eyes by the test item was observed and no clinical signs were observed.

 

Based upon the referred classification criteria (Commission Directive 2001/59/EC of August 06, 2001), FP-100 is considered to be “not irritating” to the rabbit eye.

Additional information

The primary skin irritation potential of FP-100 was investigated according to OECD test guideline no. 404. The test item was applied by topical semi-occlusive application of 0.5 g to the intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours after removal of the dressing.

 

The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0.

 

The test item caused no staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed.
