Sterillium® Rub, with its high concentration of ethanol (80% by weight) ensures rapid, but also extensive and thorough effect. It penetrates into the skin layers of the stratum corneum deeply and rapidly causing the number of organisms with the resident flora to be reduced as far as possible within two minutes. This guarantees a long-lasting effectiveness against the organisms of the resident and temporarily resident hand flora. It has been shown that the higher the concentration of alcohol, the higher its effectiveness against the resident hand flora. Sterillium Rub's distinctive initial microorganism reduction, from which the skin flora recovers very slowly, enables an excellent long-lasting effect. With Sterillium Rub, more than six hours are necessary to reach the initial organism count.
