- Details on study design:
- TEST SITE
The dorsal fur was clipped. The test substance (0.5 g) was applied on dorsal skin and covered by a linen patch on an area of about 6.25 cm². The skin was divided into two areas on both sides of the spinal column of each animal. The two areas on the left side consisted of intact skin, the areas on the right side of sacrificed skin. Each side was covered by a patch. Two were for the protection of the treated skin areas and two for the untreated control area. An bandage occluded and secured the patches.
REMOVAL OF TEST SUBSTANCE
Removal of occlusive dressing after 4 hours.
SCORING SYSTEM
Numerical scoring system as given in the OECD/EU testing guidelines.
CONTROLS
The untreated skin served as control.
EXAMINATIONS

- Dermal examination: Yes
- Other examinations: Systemic-toxic abnormalities were recorded
- No necropsy was performed in the animals

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (corrosive) based on GHS criteria
- Conclusions:
- The study and the conclusions which are drawn from it fulfill the quality criteria (validity, reliability, repeatability). Based on Regulation 1272/2008/EC (CLP), KMPS triple salt has to be classified as corrosive to skin.
- Executive summary:
Materials and methods
The skin irritating potential of KMPS triple salt was investigated in three healthy female Albino Rabbits (White Russian). A quantity of 0.5 g of moistened test material was applied to the clipped dorsal fur for a period of 4 hours under occlusive conditions. Skin readings were made 1, 24, 48 and 72 hours after removal of the occlusive dressing, and assessed for erythema and oedema. During the entire study period, animals were observed for clinical signs of toxicity and mortality.
Results and discussion
Clinical signs of toxicity/mortality: No systemic toxicity was stated and no mortalities occurred.
Irritation: Severe erythema were stated around the white coloured treated skin (mean score 24 - 72 h after exposure: 4.0). These erythema were irreversible within the post-exposure period of 14 days. Oedema were observed 1 hour after exposure (score 1.0 in case of two animals and 2.0 in case of one animal). Oedema were shown to be completely reversible within two days (possibly a result of the oxidising properties of the test material).
Coloration: the treated skin was white.
Corrosion: irreversible skin destruction of the treated skin were observed.
