PEANUT ACID

Description

Peanut acid, also known as arachidic acid, is a long-chain saturated fatty acid naturally occurring in peanut oil and other vegetable oils. This compound, with the chemical formula C20H40O2, plays a significant role in skincare formulations due to its emollient and moisturizing properties. Peanut acid helps maintain the skin's barrier function by reinforcing the lipid layer, reducing transepidermal water loss, and improving overall skin hydration.

In cosmetic products, peanut acid is valued for its ability to enhance texture and spreadability without leaving a greasy residue. It exhibits excellent stability and resistance to oxidation, making it suitable for various formulations, including creams, lotions, and lip balms. The ingredient's mild nature makes it appropriate for sensitive skin types, although caution is advised for individuals with peanut allergies.

Research suggests that peanut acid may have anti-inflammatory properties, potentially benefiting conditions such as eczema and psoriasis. Its occlusive properties also make it useful in protecting the skin from environmental stressors. When incorporated into skincare products, peanut acid can contribute to improved skin softness, suppleness, and overall appearance, making it a valuable component in moisturizing and anti-aging formulations.
