| Pharmaceutical Applications | Propylparaben sodium is used as an antimicrobial or antifungal
preservative in oral pharmaceuticals and in many water-based
cosmetics. It is generally used in combination with other paraben
esters. |
| Contact allergens | This substance is one of the parabens family. Parabens are esters formed by p-hydroxybenzoic acid
and an alcohol. They are largely used as biocides in
cosmetics and toiletries, medicaments, or food. They
have synergistic power with other biocides. Parabens
can induce allergic contact dermatitis, mainly in
chronic dermatitis and wounded skin. |

| storage | Propylparaben sodium is stable under normal conditions. It
decomposes on heating. Store in a tightly closed container. |
| Incompatibilities | The activity of propylparaben sodium can be adversely affected by
the presence of other excipients or active ingredients, such as
atropine, essential oils, iron, magnesium trisilicate, talc, polysorbate
80 and other nonionic surfactants, sorbitol, weak alkalis, and
strong acids. |
