The pH of Dove soap is 7.4, as of 2014. This is the same pH level as Palmolive Essential soap and a typical liquid soap containing aloe. This pH level is almost neutral.
The pH level of an individual's skin determines how the pH level of the soap affects her. Soaps such as Palmolive Gold and Imperial Leather Red are considered alkaline, with a pH level of 9.6. Therefore, they should be used by individuals with more alkaline skin levels. If such an individual uses soap that is not suited to her own skin's pH level, she runs the risk of having a dry skin and an aged appearance.
