Kora-Konia is a white powder, slightly greasy to the touch. Qualitative
tests showed the presence of boric acid, zinc, magnesium, a solid fatty
acid and material insoluble in hydrochloric acid containing magnesium
and aluminum. Starch was not found. Quantitative determinations gave
the following results:
Acid-insoluble material (talc) 48.3 per cent.
Magnesium (Mg++) soluble in dilute acid 1.2 per cent.
Zinc (Zn++) 4.5 per cent.
Stearic acid (impure) 39.2 per cent.
Boric acid 3.0 per cent.
Carbon dioxide (CO₂) 1.5 per cent.
From this analysis it is concluded that Kora-Konia has essentially the
following composition:
Zinc stearate U. S. P. 44 per cent.
Talc 48 per cent.
Magnesium carbonate U. S. P. 5.0 per cent.
Boric acid 3.0 per cent.
Essentially this dusting powder consists of the well-known substances
talc and zinc stearate in about equal proportions to which small
quantities of magnesium carbonate and boric acid have been added.
Inasmuch as the claim is made, by inference at least, that Kora-Konia
represents original investigation carried out “with the cooperation of
the medical profession” it should be stated that the preparation of
commercial zinc stearate was described and recommended as a dusting and
toilet powder nearly twenty-five years ago.[96]
[96] Proc. Am. Pharm. A. =40=:488, 1892.
There is nothing new or original in any one of these substances or in
the combination. The extravagant and unwarranted claims made for this
simple dusting powder are undoubtedly leading the public as well as
some thoughtless physicians, to place undeserved confidence in it.
In view of the small amount of boric acid present in the powder, its
antiseptic powers must be slight and its germicidal powers almost nil.
The Council declared Kora-Konia ineligible for New and Nonofficial
Remedies and authorized publication of this report.--(_From The Journal
