Phenoxyethanol ph stability

WebPhenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. The more stable the ion is, the more likely it is to form. One of the lone pairs on the oxygen atom overlaps with the delocalised electrons on the benzene ring. WebThe higher the lipophilicity of the oil phase and the lower the content of the aqueous phase with regard to dissolved ingredients the more preferably distributed is phenoxyethanol to the water phase and, consequently, the higher was the efficacy against the microbes.
