Description

Steareth-20 (CAS 9005-00-9) is a non-ionic O/W emulsifier based on ethoxylated stearyl alcohol. It produces stable, elegant creams and lotions and is frequently paired with stearyl alcohol or low-HLB co-emulsifiers to build viscosity and body.

Physical & Chemical Properties

• INCI: Steareth-20
• Appearance: white to off-white waxy pellets or pastilles, no odor
• Solubility: dispersible in water; soluble in alcohol and most oils at elevated temperature
• HLB value: approx. 15.3 (O/W)
• Ionic type: non-ionic
• Melting point: approx. 45–55°C
• Compatibility: good with fatty alcohols, esters and hydrocarbons

Key Benefits for Formulation

• Stable O/W emulsification: reliable cream and lotion stability
• Viscosity control: pairs with stearyl alcohol to build rich textures
• Mild non-ionic profile: suitable for sensitive and daily-use products
• Broad compatibility: works with esters, silicones and botanical oils
• Consistent quality: reproducible results across batches

Main Applications

• Creams & lotions: primary or co-emulsifier for O/W systems
• Makeup: stable emulsion bases for foundations and primers
• Body & hand care: rich, stable textures
• Hair conditioners: emulsion stability and slip
• Sunscreen: support emulsifier for UV filter systems

FAQ About Wholesale Steareth-20

What is the CAS number of Steareth-20?

CAS 9005-00-9.

What is the INCI name?

Steareth-20.

What is the HLB value of Steareth-20?

Approximately 15.3 — an O/W emulsifier.

Is Steareth-20 water soluble?

It is dispersible in water and soluble in alcohol and most oils when heated.

What is the difference between Steareth and Ceteareth?

Steareth is based on stearyl alcohol (C18); Ceteareth is based on cetearyl alcohol (C16/C18 blend). Both are non-ionic O/W emulsifiers.

What should I pair Steareth-20 with?

Stearyl alcohol and/or low-HLB co-emulsifiers for viscosity and stability.

What is the recommended dosage?

1%–5% depending on oil phase and target viscosity.
