To the Editor:—
In the article "Sulfathiazole Ointment in the Treatment of Cutaneous Infections," which appeared in The Journal, October 25, we suggested as an ointment base for the sulfathiazole equal parts of hydrous wool fat and vanishing cream.We recently have been preparing the ointment as follows: sulfathiazole 5 per cent, aquaphor (cholesterinated petrolatum) 25 per cent and cold cream 70 per cent.We believe that the ointment base prepared with aquaphor and cold cream is more satisfactory than the ointment base prepared with hydrous wool fat and vanishing cream.
