DURING recent years few ameliorative remedies used in dermato- logical practice have made such great advances towards perfection as the manufacture of medicated soaps. Although somewhat unsatis- factory, regarded as applications to the skin, owing to the transitory value of the medicament, unless a prolonged bath is indulged in, they entail a certain amount of friction, which in itself is salutary, as well as being used when the skin is in its most receptive state. A certain stress should be laid upon the amount of soap used during each bath, zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA as the quantity of water used sometimes so dilutes the medicament as to render it of very little use. For this purpose a liquid soap is to be preferred, and then what is needed for application to the skin can be added to it, adding a definite quantity to the necessary bulk of water. When this is done any ordinary superfatted soap can be used in the bath. A liquid soap I have found very useful consists of ammonium oleate in alcohol :- zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Oleic acid, 2 ozs., Alcohol, 90 per cent., 8 OZB., Solution of ammonia, a auffidenoy, Water to 6 01s. It may be perfumed with vanillin to disguise the dour of the oleate. The ammonia is added drop by drop until after vigorous shaking the VOL. x.

Its cleansing properties are far above those of ordinary soap, and the alkalinity is scarcely noticeable ; zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA it forms a valuable adjunct to the bath, especially so when a medica- ment is added to it. With ordinary soaps there should be as little moisture as possible, they should be neutral or superfatted, preferably Downloaded from https://academic.oup.com/bjd/article/10/10/355/6713316 by guest on 17 January 2023 with wool-fat, as this is so easily saponified in a soap. One point ought not to be overlooked with neutral soaps, that is the tendency water has to set up hydrolysis and so yield a trace of alkali; it is never very large, and in most cases may be neglected. The question of soap used is often very important in hospital cases. Frequently the ordinary yellow, or that employed in cleansing clothes, or even pumice and sand-soaps are used for other parts of the skin besides the hands. I have examined a dozen varieties of these soaps, and have always found plenty of free caustic alkali, and in some cases it has been quite abundant. They make the skin feel soft, but it is needless to say at what expense they do it. Cheap fancy soaps may often be included with these as injurious by their constant use. I have devised a base containing wool-fat and Lanolin soap, which can be used as an ointment, which, after application, drys into the skin, and after several hours produces a certain amount of soapiness when rubbed with water, so that a close application may be effected for the night, and excess washed off in the morning. Lanolin soap, & oz., Distilled water, 2 ozs., Anhydrous wool-fat, 4 zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBAoz. The soap is liquefied in the water and the melted wool-fat added ; the whole transferred to a mortar and vigorously triturated in order to produce a homogeneous paste. The consistency is that of resin ointment; it should be preserved in air-tight jars or made fresh. Any medicaments save free acids may be added: by free acids I mean Boric, Salicylic and Benzoic, otherwise the range is unlimited. These are suitable : Resorcin, 1 ; Coal-tar Solution, 5 ; Ichthyol, 3 ; Naphthol, 1; Creolin, 5; and Creosote, 2 per cent. To test the comparative value of washing with a medicated soap and with an ordinary one, then using the above with the medicaments, the soap being added to them, one was taken containing precipitated Sulphur, 5; Bdsam of Pern, 3; and Camphor, 5 per cent.

In the second case, after washing with an ordinary soap, the application spoken of was applied; the time required was about one minute.

It is obvious that the use of the soap and then the suggested preparation would provide a continuous application for several hours, which is so much to be desired and does away with a greasy ointment. NEW FORMULB. Here is a modification of one taken from the Chemist zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBAand zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Drtlggist :- Yolk of one egg, Lmolin, 4 oz., Roee-water, 4 oz. Triturate together the lanolin and yolk of egg, then gradually add the rose-water. This undoubtedly forms an excellent base for skin remedies. Alone it has a very penetrating and softening effect, far more so than wool-fat alone possesses. If oxide of zinc or ichthyol is added, their properties are utilized to the very best advantage. One peculiarity is noticeable with this : milk may replace the rose- water to form a cream; it may even be diluted up to three or four ounces. Naturally, it will not keep unless some antiseptic is added to it. Another wool-fat preparation is :- Wool-fat, 4 oz., Glycerine of starch, + oz., White vaseline, 1 drm. This is absorbed better than any ointment with which I am acquainted. It forms a suitable base for using formaldehyde even up to ten per cent., and no changes take place even after keeping six months. A liquid preparation is always a favourite. The combination of water with any fat facilitates its absorption. The following is a satisfactory one with naphthol :- EE2 PHARMACEUTICAL zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBANOTES. 358 zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA White liquid Vaseline, zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA8 oz., zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Alcoholic solution of soap, 3 oz., zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Glycerine, 4 oz., Naphthol, zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBAgr. x., Distilled water, to 3 ounces. There is a certain amount of free alkali in this, as alcoholic solutions of superfatted soaps cannot be made.

It is very useful in some forms, therefore I give it :- Anhydrous wool-fat, t oz., zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Camphor, 30 grs., Glycerine of subacetate of lead, 3 OZ. It could also have solution of coal-tar and glycerine subacetaie of lead, equal parts, instead of lead glycerole only. UNGUENTUM ACIDI CARBOLICI Go. Having found some difficulty with this ointment, both in its appearance and unsatisfactoriness in its keeping properties, a modifi- cation was made at our hospital on the formula: in various London hospital pharmacopaias. Its formula is :- Olive oil, Phenol, White wax, of each 1 oz., Nitrate of mercury ointment, 2 ozs., Sublimed sulphur, oz. The phenol is dissolved in the olive oil, then the white wax added and the heat continued until liquefied. After it is cold the nitrate of mercury ointment and sulphur are incorporated, using a vulcanite spatula. It is yellow, and keeps well and solid up to three months, there being no sign of turning black as in the old, and altogether produces a more satiefactory preparation. There is only one element of doubt, namely : Is the antisepticity of the phenol reduced 1 if so, I think it can be neglected, as its virtues to a large extent depend upon the nitrate of mercury ointment.
