What is "OLEIC ACID" and what does it do?

Role: EMULSIFIANT

Family: FATTY ACID

Comedogenic index: 2

Oleic acid, an omega-9 fatty acid, occurs naturally in many plants and is particularly abundant in olive oil. It plays a crucial role in various cosmetic products as an emulsifier, cleanser and texture improver.

This fatty acid may be comedogenic.

Sources and functions
Natural origin: Found in grape seeds, olives and sea buckthorn, oleic acid is the main fatty acid in olive oil.

Cosmetic uses: Used as a cleansing agent and to improve the texture of cosmetic products, oleic acid contributes to the stability of formulations.

Effects on the skin
Skin barrier: Although topical application of oleic acid can disrupt the skin barrier, this effect is mitigated when combined with other fatty acids and skin-benefiting ingredients.

Moisturizing potential: In combination with other lipids, oleic acid can improve skin hydration and reduce signs of dryness and sensitivity.
Compatibility and safety

Stability: Oleic acid is one of the most stable fatty acids, helping to preserve the efficacy of more delicate ingredients like antioxidants.

Specific considerations
Skin types: Although considered comedogenic for acne-prone skin, oleic acid is often recommended for dry and mature skin due to its nourishing properties.

Oleic acid is a versatile component in cosmetology, offering both cleansing and texture-enhancing properties, while contributing to skin hydration and care.
