Most commercial baby oils (like Johnson’s) are 98% Mineral Oil and 2% Fragrance.
Mineral Oil: A highly refined, purified ingredient that is "occlusive," meaning it creates a physical barrier on top of the skin to lock in existing moisture.
Hypoallergenic: It is designed to be extremely gentle, colorless, and free of parabens or phthalates to avoid irritating a baby's sensitive skin.
