Beitrag zur Methode der Prüfung von Hautwaschmitteln auf der Haut

Abstract

Ai1.r der Hautklinik tler Wcstfalischen Lcndesuniversitiit Miinster fDirektor: Prof. Dr. P. j o r d n nlEs wird eine neue Methode beschrieben, die durch stets gleich-maBiges Vorgehen hinsichtlich der Anschmutzung der Haut, der Art des Waschvorgangs sowie auch beziiglich der Bestimmung der Reinigungswirkung vergleichende Beobachtungen mit ausreichender Genauigkeit ermoglicht.A new method is dascribed which by uniform procedure with respect to lhe soiling of the skin, by the way of washing, and also by the determination of the cleaning effect enables compariible observations with sufficient accuracy.

Standardization of skin cleansing in vivo: part I. Development of an Automated Cleansing Device (ACiD)

“…Off all cleansing methodologies, in the past, only the device of Jacobi dealt with standardized flushing of the test fields, but then the device was unsuitable for evaluation of mechanical impact and abrasive cleansers. Following Blaich/Gerlach , test field rinsing should be done by using distilled water, because otherwise diverging water hardness can influence the reaction of detergent substances in the skin cleansing agents [e.g. formation of calcium soaps ].…”

Standardization of skin cleansing in vivo: part II. Validation of a newly developed Automated Cleansing Device (ACiD)

“…The in vivo‐ validation of ACiD represents a novelty. So far, none of the published skin cleansing machines was evaluated regarding comparability and reproducibility of the devices, neither intra‐device specific nor inter‐device‐specific . However, this seems pivotal if a standardization and wide implementation is intended.…”
