Cetearyl Alcohol – Technical & Clean Standards Overview
Cetearyl alcohol is a cosmetic-grade blend of fatty alcohols, primarily cetyl alcohol (C16) and stearyl alcohol (C18), used to improve structure, stability, and sensory performance in skin care and personal care formulations. It is a white, waxy solid derived from plant-based renewable sources or equivalent synthetic processes and is not a drying alcohol.
Technical Properties
-
INCI Name: Cetearyl Alcohol
-
Composition: Blend of cetyl (C16) and stearyl (C18) alcohols
-
Appearance: White flakes or pellets; waxy solid
-
Melting Range: Approximately 48–56 °C (118–133 °F) (grade dependent)
-
Solubility: Insoluble in water; soluble in oils and fatty phases
The blended chain lengths provide a balanced melt profile that contributes both structure and flexibility in emulsions.
Functional Role in Cosmetics
Cetearyl alcohol is multifunctional and commonly used to:
-
Thicken and structure creams and lotions
-
Stabilize emulsions, improving long-term product integrity
-
Enhance texture and slip, creating a smooth, creamy skin feel
-
Condition skin and hair, improving softness and manageability
It is widely used in moisturizers, lotions, conditioners, masks, sunscreens, and cleansing creams.
Typical Use Levels
Use levels vary by formulation goal:
-
1–3% for light thickening and stabilization
-
3–6% for standard creams and lotions
-
6–10% for rich, highly structured emulsions and hair treatments
Cetearyl alcohol is often paired with emulsifiers to optimize stability and sensory performance.
Clean Standards & Safety Profile
-
Cosmetic Ingredient Review (CIR): Determined safe for use as intended
-
Environmental Working Group (EWG): Score 1 (Low Hazard)
-
GRAS Status: Not applicable (GRAS applies to food ingredients, not cosmetics)
-
Skin Compatibility: Non-drying, low irritation potential, and well tolerated
-
Biodegradability: Readily biodegradable in cosmetic applications
Retailer Clean Compatibility
Cetearyl alcohol is widely accepted under major retailer clean standards because it:
-
Is a fatty alcohol, not a volatile or denatured alcohol
-
Has a long history of safe cosmetic use
-
Is available in plant-derived, vegan-friendly grades
-
Supports product stability and consumer safety
-
Is compatible with silicone-free, PEG-free, and sulfate-free formulations (grade dependent)
