Pentylene glycol is an ingredient that can be derived from vegetables or from petrochemicals. It is most frequently used as a preservative because it exhibits effective antifungal and antibacterial traits.
This ingredient also acts as a booster for more traditional preservatives, so it is commonly paired with other preservatives, such as phenylpropanol or chlorphenesin.
In addition to functioning as a preservative, pentylene glycol can also serve as a solvent. It is useful for dissolving substances together, that would not normally be compatible, such as water and polar emollient esters, like C12-15 alkyl benzoate.
According to the manufacturer, it also has moisturizing properties.
