Liquid paraffins are also known as "paraffin oils". In cosmetic products paraffin oils have film-forming, water-repellent properties. They support the formation of gloss on the skin (e.g. in lipsticks). Furthermore, they also serve as consistency regulators in creams and ointments; they protect the skin against moisture loss. The paraffin oils used in medicine and cosmetics are highly purified, very well tolerated and do not cause skin irritations. In comparative evaluations with vegetable oils for dry and irritated skin, their clinical efficiency is estimated to be similar to that of vegetable oils (e.g. olive oil, coconut oil).
