Brief Summary

The investigational product constitutes a medical device that is freely accessible to consumers and, as such, must be safe under real or reasonably foreseeable conditions of use and its safety must be tested before being placed on the market. Therefore, this study was designed to evaluate the biocompatibility of the experimental product, as provided for in legislation.

Outcome Measures

Primary Outcomes (1)

• Prove the absence of primary irritability potential of the experimental product under maximized conditions.

  * Occurrence of primary irritation; * Occurrence of accumulated irritation; * Occurrence of sensitization; * Occurrence of AEs ; * Treatment discontinuations due to AEs . It is expected that after the study period, the product will be considered safe because it does not promote a positive irritability response and skin sensitization in the study group. No statistical inference analysis will be performed. The results will be presented in the form of tables demonstrating whether or not there was a positive response of irritability or skin sensitization in the study group. During the study, the regions of the product and control application will be evaluated and if any clinical sign is found, it will be classified according to the scale recommended by the International Contact Dermatitis Research Group - ICDRG - (FISHER, 1995).

Study Arms (2)

Liquid bandage

EXPERIMENTAL

liquid bandage - The liquid bandage will be distributed on a contact test filter paper disc, appropriately identified, in the letter of the alphabet corresponding to the experimental product.

Device: Liquid bandage

Saline Solution

SHAM COMPARATOR

saline solution - The sterile saline solution (NaCl 0.9%) will be used as control in another contact test filter paper disc, appropriately identified, in the letter of the alphabet corresponding to the control.

Device: Saline Solution

Interventions

Liquid bandage DEVICE

The liquid bandage will be applied through a patch test to the participants' backs for 3 consecutive weeks, with 3 weekly applications. Afterwards, there will be a rest period of between 10 and 15 days. The liquid bandage will be applied again to the participants' back, in a naive area and removed after 48 hours.

Liquid bandage

Saline Solution DEVICE

The saline solution will be applied via patch test to the participants' backs for 3 consecutive weeks, with 3 weekly applications. Afterwards, there will be a rest period of between 10 and 15 days. The saline solution will be applied again to the participants' back, in a naive area and removed after 48 hours.

Model Details: Induction period (3 weeks): the experimental and control product will be applied through a patch test on the participants' back for 3 consecutive weeks, with 3 weekly applications, with the first week being the primary irritation phase and the two consecutive weeks being the irritation phase. accumulated irritation. Rest period (10 to 15 days): corresponds to the rest period, when participants will remain without any contact test applied to their back, which will follow the induction period, where there will be no application of the experimental and control product. Challenge period (3 days): the experimental and control product will be applied to the participants' back, in a naïve area. Products will be removed after 48 hours, with readings taking place after removal and approximately 24 hours after removal. This period corresponds to the sensitization phase.
