Cetearyl Alcohol – Multifunctional Fatty Alcohol for Cosmetic Formulations
✅ Fatty alcohols like cetearyl can increase moisturization in DIY cosmetics. Use it to thicken the oil phase in body butters, lip balms, lotions, sugar scrubs, and other personal care products.
✅ Technical Information
- Hydroxyl value: 215–225
- Melting point (tube rise): 49–56°C
- Iodine number: max. 0.5
- INCI name: Cetearyl alcohol
- CAS Number: 67762-27-0
- Origin: Vegetal, Synthetic
- Presentation: Small white granules, packaged in a zipped bag
- Synonyms: Fatty alcohol
- Bio-Compatible: COSMOS reference compliant
✅ Usage & Formulation
Melt with oils (e.g. almond, castor, olive, apricot, jojoba) or fatty ingredients (e.g. emulsifying wax, stearic acid). Can also be blended with other natural or synthetic waxes (e.g. candelilla, carnauba, jojoba, paraffin) to adjust product texture. Recommended usage level: 2–3% in cream-based formulas.
✅ Functional Properties
- Emollient: Softens and conditions the skin
- Emulsifying: Helps combine oil and water phases
- Emulsion Stabilizing: Improves emulsion stability and shelf life
- Foam Boosting: Enhances foam volume, texture, and stability
- Opacifying: Reduces transparency in cosmetic formulations
- Surfactant: Aids product spreadability by lowering surface tension
- Viscosity Control: Adjusts product thickness as needed
✅ Why It’s Safe & Effective
Cetearyl alcohol is a mix of cetyl and stearyl alcohol — both fatty alcohols known for being non-drying and skin-safe. Unlike low molecular weight alcohols (like denatured alcohol), cetearyl alcohol provides long-chain, oil-soluble benefits. It’s ideal for enhancing the feel and function of lotions, creams, and balms — without irritation.
A multitasker for any formulator — boost hydration, texture, and stability in one simple step with cetearyl alcohol.
