Biosativa has passed the "Human patch test" which complies with DIN EN ISO / IEC 17025. This test is designed to evaluate primary skin irritation and existing sensitizations with human subjects after a single application of an active agent.
"None of the 30 subjects showed any skin changes 24, 48 and 72 hours after the applied patch testing, which is accredited in compliance with DIN EN ISO / IEC 17025 and in compliance with international recommendations of the ICDRG and guidelines of the DDG and DGAKI. The negative controls showed no positive reactions. Therefore, it can be concluded that the practical use of the product under normal conditions does not lead to any unwanted skin reactions due to skin irritating effects."
