Materials and methods
Test guidelineopen allclose all
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 405 (Acute Eye Irritation / Corrosion)
- Deviations:
- not applicable
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method B.5 (Acute Toxicity: Eye Irritation / Corrosion)
- Principles of method if other than guideline:
- Before OECD Guideline 405 was first adopted in 1981, eye irritation was tested using a BASF test.
The methods were based on Draize (Federal Register 38, No. 187, § 1500.42, p. 27019 (1973-09-27)). - GLP compliance:
- no

- Reaction mass of bis(2-hydroxyethanaminium) sulfite and 2-(methylamino)ethanol - oxosulfane oxide (1:1)
- Details on test material:
- - Name of test material: Kauramin-Härter CE 5196 flüssig; N-Methyläthanolammonium(-hydrogen) sulfit + Äthanolammonium(-hydrogen) sulfit in Wasser (German)
- Physical state: liquid
- Composition of test material, percentage of components: N-Methylethanolamine: 21 %, Ethanolamine: 24.6 %, Sulfur dioxide: 35 %, Water: 19.4 %
- Other: pH-neutral mixture

- Number of animals or in vitro replicates:
- 3 rabbits
- Details on study design:
- SCORING SYSTEM:
Draize scoring system
Based on the Draize scores, a primary irritation index was calculated (max. score: 110/9).

- Irritant / corrosive response data:
- Slight conjunctival redness was the only test item-related finding noted. The mean scores (24/48/72 hours) for this endpoint were 1 in 2/3 rabbits and 0.7 in the remaining rabbit. Reversibility was not reported; however, 1/3 rabbits showed no signs of conjunctival redness at the 72-hour reading.
The primary irritation index was calculated to be 1.8.
