Cetearyl Alcohol (also Cetostearyl Alcohol, C16-18 Alcohols, or Fatty Alcohols) is a multifunctional fatty alcohol compounded from cetyl alcohol (C16) and octadecyl alcohol (C18), Cetostearyl alcohol is core functions including:
Emulsion stabilization: to enhance the emulsion interfacial film strength, to prevent delamination (cream / lotion must) natural thickening: to enhance the viscosity of the system, optimize the texture and feel (dosage of 0.5% -5%); optimize the feel of the skin: to give a sense of silky smooth moisturizing, reduce the surface of the living stimulation (suitable for shampoo / cleansing face) high safety: EWG1 certification, non-acnegenic, infants and sensitive skin suitable.
✅ Dual-action: emulsification + thickening at the same time
✅ Versatile and compatible: suitable for anionic/cationic and oily systems
✅ Green and safe: no concentration limitation, good biodegradability
Cetostearyl Alcohol Key Functions:
Emulsifier & Stabilizer: Its primary role. Cetearyl alcohol helps form stable oil-in-water (O/W) or water-in-oil (W/O) emulsions, preventing the mixture from separating.
Thickener: Increases the viscosity of creams and lotions, giving them a rich, luxurious texture.
Emollient: Forms a protective film on the skin/hair, preventing moisture loss and providing a soft, smooth feel.
Co-emulsifier/Opacifier: cetearyl alcohol often used in combination with primary surfactants to enhance emulsion stability and appearance.
- Cetostearyl Alcohol Application:
Skincare: Creams, lotions, moisturizers, body butters.
Hair Care: Conditioners, hair masks (provides slip and softness).
Pharmaceuticals: As an ingredient in ointments, creams, and lotions.
Personal Cleansing: Some soaps and cleansers.






Found in creams, lotions, conditioners, ointments, and sunscreens.It Creates rich, stable textures, prevents separation, and helps skin retain moisture.
