INDUCTION EXPOSURE: Days 0 – 7
On day 0, an area of 40 mm x 60 mm of hair was clipped from each animal using veterinary clippers and three pairs of 0.1 ml intradermal injections
were made on either side of the mid-line. The injections were:
a) Freund’s Complete Adjuvant plus distilled water at a ratio of 1:1
b) 0.1 % w/w formulation of the test material in distilled water
c) 0.1 % w/w formulation of the test material in a 1:1 preparation of Freund’s Complete Adjuvant plus distilled water.
Approximately 24 and 48 hours later, the degree of erythema at the test material injection sites (injection b) was evaluated. On day 7, the same area
was clipped again on each animal and treated with a topical application of test material (50 % w/w in distilled water) and held in place with occlusive
dressing for 48 hours. After 1 and 24 hours, the degree of erythema and oedema was evaluated after removal of the dressings.
Induction of the control animals was performed in an identical manner as for the test animals, except that the test material was ommitted.
The scoring schedule for erythema was derived from 'Modified OECD Test Guideline 406, 1992 and Method B6 Skin Sensitisation of Commission Directive 96/54/EEC' and the scoring schedule for oedema was taken from Draize, J.H. 1977. see Table 1.
CHALLENGE EXPOSURE: Day 21; see Table 1
On day 21, an area of 50 mm x 70 mm on both flanks was clipped free of hair and a filter paper patch loaded with test material at the maximum non-
irritant concentration (5 % w/w in distilled water) was applied to the right flank of each animal and held in place with surgical tape and an occlusive
dressing. To ensure the maximum non-irritant concentration was used at challenge, the test material was applied in a similar method to the left flank at a concentration of 2 % w/w in distilled water.
The dressings were kept in place for 24 hours, the dressing was then removed and the challenge sites swabbed with cotton wool soaked in distilled
water to remove residual material. After approximately 24 and 48 hours after challenge dressing removal, the degree of erythema and
oedema was evaluated. Any other reactions were also recorded. The scoring schedules used were the same as those outlined above for the
inductrion exposure stage (also see Table 1).
There was no rechallenge. - Challenge controls:

Pilot study
Intradermal induction sighting test:
The highest
concentration causing only mild to moderate skin irritation which was
well tolerated systemically (0.1% w/w) was selected for the intradermal
induction stage of the main study.
Topical induction sighting test:
The highest
concentration applied causing only mild to moderate dermal irritation
which was well tolerated systemically (50% w/w) was selected for the
topical induction stage of the main study.
Topical challenge sighting test:
The highest non irritant concentration of the test material and one lower concentration were selected for the topical challenge stage of the main study (5% and 2% w/w in arachis oil BP).

- Executive summary:
Materials and methods
The study was performed to assess the contact sensitisation potential of copper carbonate in the albino guinea pig. Ten test and five control animals were used for the study. Two phases were involved; an induction of a response by intradermal injection and topical application, and a topical challenge of that response. Based on the results of sighting tests, the concentrations of the test material for the induction and challenge phases were selected as;
Intradermal induction: 0.1% w/w in distilled water
Topical Induction: 50% w/w in distilled water
Topical challenge: 2 and 5% w/w in distilled waterOn day 0, approximately 24 and 48 hours after the initial intradermal induction injection (0.1% w/w), the degree of erythema was evaluated. Seven days later, the same area used for the intradermal injection was treated with a topical application of test material (50% w/w). The degree of erythema and oedema was evaluated 1 and 24 hours after removal of the patches. Induction of the control animals was performed in an identical manner as for the test animals, except that the test material was ommitted.
On day 21, test material was applied at the maximum non-irritant concentration (5% w/w) and a lower concentration (2% w/w) as challenge doses. Approximately 24 and 48 hours after removal of the challenge doses, the degree of erythema and oedema was evaluated and any other skin reactions were recorded.
The study was conducted according to Commission Directive 96/54/EC Method B6 Acute Toxicity (Skin Sensitisation) and OECD Guidelines for the Testing of Chemicals No. 406 'Skin Sensitisation' (adopted 17 July 1992). The study was also conducted according to GLP. No deviations from the test guidelines, or deficiencies in the method were reported.
Results and discussions
No skin reactions were noted at the challenge sites of the test or control animals at the 24 or 48-hour observations at the 2% and 5% w/w concentrations. Therefore, under the conditions of the test, the test material produced a 0% (0/10) sensitisation rate and was classified as a non-sensitiser to guinea pig skin.
