| 配方組成： |
Benzyl alcohol/170 cc.
Sodium lauryl sulfonate/64 gm.
Anhydrous lanolin (melted)/20 cc.
plus additional benzyl alcohol as indicated below.
n-butyl-p-aminobenzoate/100 gm.
Cornstarch/640 gm. |
| 配制方法： |
the n-butyl-p-aminobenzoate is dissolved in the benzyl alcohol, which is first warmed, making an approximately saturated solution. The melted lanolin is added, and the mixture is kept warm and stirred until as much of the lanolin as will dissolve is in solution. While the liquid is warm, it is added slowly, a little at a time, to a thorough mixture of the cornstarch and the sodium lauryl sulfonate, and the whole is carefully kneaded to distribute the liquid evenly throughout the powder.
An additional amount of benzyl alcohol, about a tenth of that already used, is added as before to give the material a desired consistency. The final preparation should be a doughy, nongreasy, cakelike material that can be packed in ointment jars. |
