Several quaternary ammonium
compounds have been tested and found relatively nontoxic and sufficient
nonirritating for use in cosmetic preparation. Quaternaries are particularly
suitable for aqueous deodorant preparation. But they stick in to the body and
are not easily removed.
Hence the antibacterial and
deodorant spray can be prepared, without toxic antiperspirant properties.
(0.5-2% of quaternary in water or 5% denatured alcohol of cosmetic grade)
The water soluble derivatives
of chlorophyll potassium, copper chlophyllin, sodium derivatives of
chlorophyll, sodium magnesium chlophyllin have satisfactory deo-qualities.
Chlorophyll derivatives can be used in combination with quaternaries too for
the cream or deodorant solution.
If chlorinated phenol
derivatives is used in liquid it must be dissolved in propylene glycol and
alcohol as iron causes discoloration. It is absolutely necessary to eliminate
iron contamination from other ingredients or from equipment when they are used.
These deodorants when mixed
in 0.25% concentrations are effective antibacterial products.
