Antifungal Performance of Salicylic Acid and Its Compound System
Salicylic acid as the main research object,the antifungal performance of salicylic acid and blending p-hydroxyacetophenone,1,2-hexanediol,p-anisic acid and raspberry ketone was studied by microbial challenge test.Results showed that with the increase of salicylic acid mass fraction and the decrease of pH,the effect of antifungal was enhanced.When the mass fraction of salicylic acid was 0.5%and the pH is less than 5.0,the addition of 0.3%-0.5%p-hydroxyacetophenone,0.05%-0.2%p-anisic acid,0.5%raspberry ketone,and blending 0.3%p-hydroxyacetophenone and 0.3%1,2-hexanediol all in mass fraction could improve the antifungal effect.The results of salicylic acid compounding can provide guidance for the preservative system of cosmetics.
