- Evaluation of Primary and Cumulative Skin Irritation

- Assessment of patch comedogenicity

- Evaluation of Dermal Sensitization

- Photoirritation Assessment

- Photosensitization Assessment

- Soap Chamber Test (for rinsable products with surfactants)

- Elbow Test/PC5

- Behind the Knee Test (for absorbents)

- Ocular Irritability ("Does not irritate eyes" / "Tear Free")

- Ocular Tolerance ("Does not drip into eyes")

2. Acceptability Studies (In Home Use Test)

Aims to prove the harmlessness of the product under normal conditions of use with the target audience. 

- Dermatological and/or pediatric, ophthalmological, gynecological, urological, dental acceptability

- Acnegenicity and comedogenicity evaluation in use
