Cosmetic Grade Octyldodecanol（CAS 5333-42-6）
Cosmetic Grade Octyldodecanol is a high-purity long-carbon branched-chain saturated fatty alcohol refined by professional hydrogenation purification and multi-stage fractionation technology. As a premium high-efficiency moisturizing emollient and formula stabilizer, it has a longer C20 molecular chain than conventional C18 branched alcohols, featuring stronger moisturizing and barrier repair capabilities while maintaining ultra-low temperature fluidity and non-greasy texture.
It solves the common pain points of traditional moisturizing raw materials such as insufficient water-locking power, heavy greasy feeling and easy low-temperature solidification. It can form a breathable moisturizing film on the skin surface to achieve long-lasting moisturizing and softening effects, and significantly optimize the smoothness and delicate texture of cosmetic products.
It has excellent solubilizing and emulsifying auxiliary performance, effectively improving the high and low temperature resistance and storage stability of formulas. With dual skin and hair care effects, mild formula properties and wide compatibility, it is the preferred core raw material for high-end moisturizing repair and all-season stable cosmetic products.
Key Benefits
• Longer Carbon Chain & Ultra-Strong Moisturizing: Unique C20 long branched chain structure, stronger water-locking and film-forming capacity than C18 alcohols, long-lasting moisturizing effect, effectively improve chronic dry and rough skin.
• Ultra-Low Temperature Resistance & No Solidification: Permanent liquid state at low temperature, excellent fluidity, completely avoid formula agglomeration, texture deterioration and delamination in cold winter environments.
• High Moisture & Non-Greasy Balance: High-efficiency moisturizing factor integration, strong dry-relieving effect, silky spreading texture, no sticky or heavy residue, create high-grade refreshing and moisturizing skin feeling.
• Excellent Formula Stabilization: High electrolyte tolerance and emulsifying auxiliary performance, significantly improve the high and low temperature stability of creams and lotions, prevent water precipitation and viscosity attenuation, extend shelf life.
• Dual Skin Barrier & Hair Repair: Repair damaged skin barrier, relieve dry peeling and tightness; smooth hair cuticles, reduce static frizz and tangling, restore hair softness and luster.
