The effectiveness range of the active components, the alcohols
ethanol and 1-propane, includes gram-negative and gram-positive
bacteria, incl. myco-bacteria, fungi and viruses.
Alcohols are also effective against antibiotica-resistant
strains of bacteria (i.e. MRSA). The effect against bacteria-spores
is incomplete. The anti-microbial effect of the alcohols stems most
likely from the de-naturizing of proteins. The effect is barely
lowered in presence of blood, protein, serum or other organic
compounds. Alcohols exhibit much less anti-microbial effect in an
anhydrous condition, than in dilutions. The optimal effect in the
alcohols is at 60 - 90 % v/v (approx. 50 - 70 % m/v). In mixtures,
the alcohols ethanol and 1-propane act like additives, meaning the
total concentration of alcohols determines the effectiveness of the
Effectiveness of Softa-Man
Softa-Man contains 45 % m/v ethanol and 18 % m/v 1-propane (63 %
m/v total alcohol content). The following effects have been proven
for his pharmaceutical product:
Bacteria (includes myco-bacteria), fungi, as well as enveloped
viruses (Classification: "limited virucidal")* and rotavirus.
Transient skin-flora (hygienic
In artificial contamination, Softa-Man reaches the
germ-reduction on the skin required for rub-in processes, according
to EN 1500, within 15 seconds. Because of current recommendations
for hygienic hand-disinfection, however, a reaction time of 30
seconds should be observed.
Resident skin-flora (surgical
Softa-Man meets the requirements of the EN 12791 after 60
seconds. After this reaction time, the resident (natural)
skin-flora is visibly reduced for a time frame of 3 hours.
Effect against viruses
Softa-Man inactivates the test viruses BVDV (surrogate virus for
Hepatitis-C virus) and vaccinia-virus in in-vitro tests within 30
seconds. The results, based on current knowledge, lead to the
conclusion of effectiveness against other enveloped viruses, i.e.
HBV and HIV. The un-enveloped rotavirus is also inactivated within
30 seconds through Softa-Man in in-vitro tests.
