ABSTRACT
Objective To study the microorganism viability in compound resorcinol lotion ,confirming with bactericidal compound resorcinol lotion .Methods 5 bottles of compound resorcinol lotion were respectively added Escherichiacoli ,Staph‐ylococcus aureus ,Bacillus subtilis ,Candida ,Aspergillus niger ,placed 24 h ,then the membrane filtration method was used respectively in 5 species of microbial limit test .Results In compound resorcinol lotion ,5 microbial strains were not given birth to bacterium ,were killed ,the recovery rate was zero .Conclusion Microbial cannot survive in compound resorcinol lotion .
ABSTRACT
OBJECTIVE:The content of resorcinol in compound resorcinol lotion was determined by dual wavelength spec?trophotometry.METHODS:Absorbance was determined by using water as the solvent at the wavelength273.5nm and266.1nm.RESULTS:The results showed that the standard curve of resorcinol concentration ranging from20.32?g/ml to60.96?g/ml was in correspondence with Beer’s law.The absorbance difference and the concentration showed a good linear relationship(r=0.9998).The mean recovery of resorcinol was(99.59?0.45)%(n=9).CONCLUSION:This method is simple,quick and ac?curate.
