Arachidonic Acid

Product Description

Direct factory supply of high-purity Arachidonic Acid (CAS 506-32-1), a C20:4 omega-6 polyunsaturated fatty acid supplied under nitrogen-protected cold-chain handling. Each lot includes batch COA traceability for accountable B2B cosmetic-grade procurement.

As an essential membrane lipid precursor, arachidonic acid integrates into stratum corneum lipid lamellae, supporting barrier flexibility and emollient conditioning. Its four cis double bonds distinguish it from saturated emollients in lamellar lipid restoration.

Formulators specify arachidonic acid for barrier-repair balms, mature-skin facial oils, and lip treatments where omega-6 PUFAs complement ceramide–cholesterol matrices in anhydrous delivery systems.

Key Benefits & Applications

Arachidonic Acid delivers omega-6 lipid replenishment, barrier emolliency, and TEWL support in anhydrous and oil-phase skin care systems.

• Replenishes C20:4 omega-6 PUFA fractions in stratum corneum lipid matrices.
• Supports barrier cohesion as a polyunsaturated fatty acid emollient in face oils.
• Helps reduce TEWL in lipid-depleted mature-skin cream and balm systems.
• Conditions rough, flaky skin in anhydrous serums and oil-phase emulsions.
• Supports flexible lipid lamellae in aging-skin barrier-repair leave-on treatments.

Formulation Guidelines

Arachidonic Acid is a highly unsaturated oil-phase active; follow antioxidant protection and low-temperature handling below.

• Use at 0.01–1.0% w/w in face oils and balms; higher levels increase oxidation risk (Typical).
• Add to oil phase under inert atmosphere; pre-blend with tocopherol at 0.1–0.5% (Typical).
• Protect from heat, light, and oxygen throughout manufacturing and filling (Typical).
• Compatible with ceramides, cholesterol, and plant oils in lamellar barrier formulas (Typical).
• Suitable for lip balms, mature-skin facial oils, and post-treatment recovery anhydrous serums (Typical).
• Synergy: Pair Ceramide NP at 0.2–1% with arachidonic acid to reinforce lamellar barrier lipids in repair balms.
