Light Liquid Paraffin (LLP), also known as Paraffinum Liquidum, Paraffin Oil, or Russian Mineral Oil, is a highly refined mineral oil used in cosmetics and medicine. It should not be confused with paraffin used as a fuel. The term “paraffin” can refer to alkane hydrocarbons, leading to regional differences in the use of both “paraffin” and “paraffin oil” terms.

LLP is a transparent, colorless, nearly odorless, and oily liquid composed of saturated hydrocarbons derived from petroleum. It is widely used for its applications in both the cosmetic and pharmaceutical industries due to its purity and inert properties.
