Characteristics of peanut oil
Peanut oil is characterized by a light yellow, golden color, which depends on the method of pressing and the degree of purification of the oil. The oil has a mild, mildly nutty smell, which gives cosmetics a pleasant natural aroma. In the case of unrefined oil, the smell is more pronounced, characteristic of peanuts, while refined oil is almost odorless making it a suitable base for perfumed cosmetics. Peanut oil is rich in many fatty acids with beneficial effects on skin and hair, including:
- Linoleic acid (Omega-6) – with regenerative and moisturizing effects,
- Oleic acid (Omega-9) – with nourishing and softening effects on the skin,
- Palmitic acid – forms a protective layer on the surface of the skin, preventing water loss,
- Stearic acid – with soothing and calming effects.
In addition, peanut oil is rich in vitamin E, a powerful antioxidant that protects cells from free radicals, delaying the aging process.
