Non-ionic O/W emulsifier for creams, lotions, sunscreens, shampoos, hair conditioners and pharmaceutical creams; can be used with Ceteareth-12 & cetearyl alcohol
Ceteareth-20 (CAS 68439-49-6) is a non-ionic emulsifier produced by the condensation of cetearyl alcohol with 20 moles of ethylene oxide. It appears as a white to off-white waxy solid or flake.
Featuring outstanding emulsifying, dispersing, solubilizing and stabilizing performance, it has an HLB value of around 15.2–16.0, making it an ideal emulsifier for preparing O/W (oil-in-water) emulsions.
Ceteareth-20 is widely applied in creams, lotions, sun care products, shampoos, hair conditioners and pharmaceutical creams. It can be used independently or in combination with Ceteareth-12, cetearyl alcohol and other co-emulsifiers.
As a professional source manufacturer, we provide high-purity Ceteareth-20 and support stable bulk supply.

Key Application
1. Creams & Lotions: Key O/W Emulsifier
Ceteareth-20 is a classic emulsifier for producing oil-in-water (O/W) emulsions. When compounded with Ceteareth-12 or cetearyl alcohol, it delivers a more stable emulsifying system.
Face & Moisturizing Creams: Ensures fine emulsification and excellent spreadability.
Lotions: Provides a lightweight skin feel and fast-absorbing properties.
Sunscreens: Helps evenly disperse sunscreen agents to improve SPF performance and skin feel.
Recommended dosage: 1% – 5% (better effect when used in combination with Ceteareth-12)
2. Personal Care Products
Shampoos: Acts as a solubilizer and emulsifier to disperse fragrances and oil ingredients.
Hair Conditioners: Compatible with cationic conditioning agents to deliver smoothness.
Body Washes: Improves product texture and foaming performance.
3. Pharmaceutical Creams
Topical Drug Carriers: Serves as an emulsifying base for skin creams and ointments.
Transdermal Preparations: Helps evenly distribute active pharmaceutical ingredients and promote absorption.
4. Industrial Applications
Textile Auxiliaries: Used as a fiber softener and emulsifier.
Pesticide Formulations: Applied as an emulsifier for pesticide emulsifiable concentrates.
