    Petrolatum (white) 8009-03-8 ≥99.0%
    Petrolatum (white) is mainly composed of hydrocarbons, possesses strong water resistance and moisturizing properties, and is commonly used as a pharmaceutical excipient. Petrolatum (white) penetrates into stratum corneum cells, improves skin barrier function, repairs epidermal structure, and reduces transepidermal water loss and the risk of skin damage. Petrolatum (white) induces the expression of antimicrobial peptides, innate immune genes, filaggrin and loricrin. Petrolatum (white) is used in research on atopic dermatitis and post-operative skin infections.
