White Mineral Oils
White mineral oils—also known as liquid paraffins—are highly refined, saturated hydrocarbons used extensively in pharmaceutical and personal care formulations. Their inert nature, exceptional purity, and chemical stability make them ideal carriers, lubricants, and protectants in a wide range of medicinal products. These oils meet stringent pharmacopeial standards (USP, NF, Ph. Eur.) and are trusted for their safety and versatility.
Key Characteristics of White Mineral Oils
Inert and non-reactive: Do not interfere with active ingredients
Highly purified: Free from aromatics, sulfur, and nitrogen compounds
Colorless, odorless, tasteless: Ideal for sensitive applications
Hydrophobic and non-comedogenic: Repels moisture and doesn’t clog pores
Stable under heat and oxidation: Long shelf life and formulation integrity
Functional Benefits in Pharmaceutical Use
Acts as a base or carrier in ointments, creams, and lotions
Provides moisturizing and emollient properties for skin treatments
Serves as a protective barrier in topical applications
Used in gelatin capsules and laxatives for oral administration
Supports vaccine formulations and veterinary medicines
