Sodium Coceth Sulfate ●
TL;DR. This ingredient is an anionic cleansing surfactant used to lift oil and soil, create foam, and support rinse-off performance in shampoos, body washes, and facial cleansers.
What does Sodium Coceth Sulfate do in a cosmetic formula?
This ingredient is an anionic cleansing surfactant used to lift oil and soil, create foam, and support rinse-off performance in shampoos, body washes, and facial cleansers.
Is Sodium Coceth Sulfate clean?
From a clean-beauty perspective, it has friction because it can be drying or irritating at higher active levels, especially in formulas with low buffering or limited mildness support. Because it is made through ethoxylation, brands often scrutinize potential trace processing residues such as 1,4-dioxane.
Is Sodium Coceth Sulfate sustainable?
This material is typically based partly on coconut or palm-kernel fatty alcohols and partly on petrochemical ethylene oxide chemistry. It is generally considered readily biodegradable, but its feedstock pathway and ethoxylated processing make it less aligned with stricter natural-product frameworks.
Is Sodium Coceth Sulfate COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because ethoxylated ingredients are outside the standard’s allowed processing framework. Its biodegradability is a positive, but the petrochemical input and residue-control requirements weaken its Green Chemistry profile.
How does Sodium Coceth Sulfate work chemically?
The molecule is a mixture of anionic sodium salts built from fatty alcohol chains that have been ethoxylated and then sulfated, giving strong detergency and foam through micelle formation. It is usually used in rinse-off systems with amphoteric or nonionic co-surfactants to reduce irritation, and it performs best in mildly acidic to neutral cleanser pH ranges.
