Arachidic Acid is a long-chain saturated fatty acid (C20). INCI: Arachidic Acid. In a formula it works as an emollient, thickener, and emulsion stabilizer: it softens skin, gives creams body, and helps hold oil and water in one phase. It is a functional component, not a skincare active. It is often part of the waxy structural portion of a formula. Pregnancy safety. Systemic absorption through intact skin is negligible and there is no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, suitable for sensitive skin.
