TALL OIL.

Valuable CAS 8002-26-4 / SKIN CONDITIONING

Tall Oil, a natural fatty acid blend, serves as a dynamic multi-functional ingredient in skincare formulations. It efficiently cleanses and emulsifies, while simultaneously delivering significant moisturizing, skin conditioning, and anti-inflammatory benefits through its rich content of unsaturated fatty acids.

Emollient Solvent Skin Conditioning Cleansing Agent Emulsifier Moisturizer Anti-inflammatory

Science

Mechanism of Action

Tall Oil Acid and its salts function as cleansing agents and emulsifiers by reducing surface tension and aiding the emulsification of water with oil and dirt. Distilled Tall Oil (DTO), a key component, delivers moisturizing benefits by forming a protective layer that diminishes transepidermal water loss (TEWL) and by providing unsaturated fatty acids (oleic and linoleic acids) that enhance the skin's natural moisturizing factor (NMF). Furthermore, it exhibits anti-inflammatory properties by inhibiting inflammatory mediators like cytokines and prostaglandins, which helps alleviate redness, swelling, and itching, while also conditioning the skin for improved texture and suppleness.
