Lanolin (CAS 8006-54-0) appears in 4 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is readily biodegradable.
Non-toxic natural product. Rare contact allergen in wool-sensitive individuals (< 1% of population).
Lanolin is the natural oil extracted from sheep's wool — it's what makes sheep waterproof. In leather conditioners, it replaces the natural oils that automotive leather loses over time due to UV exposure, heat cycling, and friction.
It's the gold standard leather conditioning ingredient because its molecular structure is similar to the oils in natural skin. Penetrates leather fibers rather than sitting on the surface. Completely safe — used in nipple creams, lip balms, and baby products.
