Brief Summary

| |

| --- |

|An Open label, Non-randomized and intra-subject comparison of repeated insult patch test study to evaluate the cutaneous irritation potential of three experimental investigational products, including a control.

Following provision of informed consent and completion of all screening assessments, eligible subjects will be enrolled in the study.

Study is conducted over a period of 37 days for each subject. Products will be evaluated through repeated application via occlusive patches onto the dorsum scapular region skin of healthy males & behind upper left arm for healthy females for a 24-hour period on D1, D3, D5, D7, D9, D11, D13, D15, D17& post patch removal evaluation shall be done by Principal investigator for grading.

Patches will be removed after 24 hours and the skin will be assessed for any signs of irritation on D2, D4, D6, D8, D10, D12, D14, D16, D18, this phase of the study is called as Induction Phase.

From D19 till D32- resting Phase will be there where in no study activities shall be performed, this will be wash out period. From D33 till D36 Challenge phase will be there, where in subjects will be applied Patch on D33, removal shall be done after 24 hours, Dermatologic evaluation will be done 24 hours post patch removal, then post 48 hours, & lastly post 72 hours.

**Assessments**

Subjects will undergo visual evaluations of dermal irritancy performed by a trained assessor on D2, D4, D6, D8, D10, D12, D14, D16, D18 in induction phase. Once again visual evaluations of dermal irritancy performed by a trained assessor on D35, D36, D37 in Challenge phase.

The Draize scores will be analyzed to establish the irritation potential of each test product in Induction phase. While in Challenge phase ICDRG scale will be used to see the irritation potential of each test product.

Subjects will be assessed for frequency and severity of adverse events.
