The Hand Sanitizer Lotion with Invisicare was applied to fritted glass membranes to simulate a normal application on skin. The membranes were subjected to an agitated 5% Ammonium Hydroxide wash with tests being conducted over six hours. Gravimetric analysis was used to determine the level of adherence to the glass membranes. An additional test with artificial perspiration yielded no change in persistence.
- 82% remained bonded to membrane after 3 hours.
- 68% remained bonded to membrane after 6 hours.
Note: Additional clinical studies measuring Trans-epidermal Water Loss (TEWL) and Corneometer measurements show that the Hand Sanitizer Lotion with Invisicare exhibits selective impermeability required to allow for normal respiration and prevent hazardous environmental challenge.
