The keratolytic effect of salicylic acid was measured with a colorimeter after staining the outer layers of the stratum corneum with silver nitrate. Salicylic acid was used in a concentration of 5% or 10% in vaseline or of 5% in an improved vehicle. The results of two experiments showed that improvement of the vehicle increased the keratolytic effect of salicylic acid and that urea played a major role in this improvement.
在用硝酸银对角质层外层进行染色后，使用比色计测量水杨酸的角质剥脱作用。水杨酸在凡士林制剂中的浓度为5%或10%，在改良载体中的浓度为5%。两项实验结果表明，载体的改良提高了水杨酸的角质剥脱作用，且尿素在这种改良中起主要作用。
