White Petrolatum: Occlusive Ointment Base and Skin Protectant
White petrolatum (white soft paraffin, white petroleum jelly) is a purified, decolorised semi-solid mixture of hydrocarbons obtained from petroleum. It is the most widely used occlusive emollient in dermatological formulation, forming a hydrophobic barrier on the skin that reduces transepidermal water loss (TEWL) by over 98%. White petrolatum is the reference standard against which all other moisturisers are compared for occlusivity.

Formulation Applications
White petrolatum is the base of the USP/EP simple ointment and serves as the vehicle for numerous topical drug products (corticosteroids, antibiotics, antifungals). It is the primary component in wound care products where occlusion promotes moist wound healing. In ophthalmology, it is the standard vehicle for eye ointments. Dermatologists recommend it as a first-line emollient for eczema and dry skin conditions due to its hypoallergenic nature and absence of preservatives, fragrances, and stabilisers. It also serves as a protectant in lip balms and barrier creams, and as a lubricant for nasal cannulae and medical devices.
