Details |
| Comparator Agent |
0.9% Isotonic Saline- Negative Control |
0.04ml of Isotonic Saline solution will be applied on the volunteers back on alternate days and scoring done on alternate days. Duration of occlusion will be 24 hours. A total of 9 applications will be carried out. The participants will be asked to return after a rest period of 10-14 days for Challenge phase. Patches will be applied on the first visit and removed after 24 hours. Scoring will be carried out after 48 hours, 72 hours, 96 hours. |
| Intervention |
Venusia Baby Bathing Bar |
Baby Bathing Bar will be diluted to the highest non- irritant concentration.
Procedure for determining highest non- irritant concentration: A series of dilutions will be
applied on upper arm/back of 5 – 10 participants and occluded. Patches will be removed at 24
hours and reactions graded at 48 hours. Then the highest non- irritant concentration of product will be determined based on these reactions and this concentration will be used for the study. Filter papers dipped in diluted test product (to contain approximately 0.04 ml of solution), will be filled in well of patch chambers and will be applied occlusively on the back of each participant for a duration of 24 hours. A total of 9 applications will be carried out. The participants will be asked to return after a rest period of 10-14 days for Challenge phase. Patches will be applied on the first visit and removed after 24 hours. Scoring will be carried out after 48 hours, 72 hours, 96 hours. |

Brief Summary
Modification(s)
|
Topical exposure to chemicals can lead to adverse skin effects or skin intolerances. While some chemicals will only trigger an irritant response after repeated exposure of the same skin area, other chemicals will even after a one-time exposure cause irritation. HRIPT is a standard test; usually performed to check the tolerance of a product on skin after repeated application of those products on the same site. Sensitization is the process by which a person becomes, over time, increasingly allergic to a substance through repeated exposure to that substance. It is very different from irritation because it involves immune response, the reaction becomes worse with repeated exposure, and it is usually specific to individuals. The HRIPT consists of 2 phases, possibly 3. Phase I is the Induction Phase where product is applied to the skin 9 times over duration of 3 weeks. This is a followed by rest period of 10- 14 days after which the skin is exposed to the product again in Phase II or the Elicitation Phase. A response in Phase II is usually allergic in nature. In some cases when reactions at challenge are weak or do not follow a consistent pattern, it may be necessary to conduct additional studies on a participant to determine if the responses are indicative of allergy. This is Phase III of the study- Rechallenge Phase. A Rechallenge may also be performed to verify that the response is persistent.
Result: The study was completed as per protocol with 216 complete cases. |
