Description of key information
In a skin sensitization test with guinea pigs according to OECD Guideline 406, no change was observed on the skin of the animals in the test item group following challenge, while skin reactions were observed in all animals of the positive control group.
Key value for chemical safety assessment

- key study
- Study period:
- 1998
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- GLP compliance:
- not specified
- Type of study:
- guinea pig maximisation test

- This study was performed in 1998.
- Specific details on test material used for the study:
- Name: Sodium cocoyl glycinate (GCS-12)
Lot No.: 970925
Description: Clear liquid
Composition: 31.5% solution
Storage: Cool, dark place - Species:
- guinea pig
- Strain:
- Hartley
- Sex:
- female
- Details on test animals and environmental conditions:
- 50 female Hartley guinea pigs were purchased from Charles River Japan, Inc. After the one-week quarantine and acclimatization period, 45 guinea pigs that showed no abnormality were selected and assigned to the vehicle control group, the test article group or the positive control group.

- Details on study design:
- Induction:
Intradermal: 5% (concentration for induction was based on the concentration in final products)

- Executive summary:
A skin sensitization study was conducted in guinea pigs using the maximization method. Distilled water for injection was used as a vehicle control, and 2,4-dinitrochlorobenzene was used as a positive control. No change was observed on the skin of the animals in the test item group following challenge, while skin reactions were observed in all animals of the positive control group.

Justification for classification or non-classification
In an experimental study with guinea pigs, the test item gave no indications for a possible skin sensitization. Therefore, there is no need for classification and labelling of the test item according to CLP Regulation 1272/2008/EG.
