Coceth-7 ●
TL;DR. This ingredient is a nonionic surfactant and solubilizer used to help disperse oils, fragrance components, and oily actives into water-based formulas. It can also support mild cleansing and emulsion stability.
What does Coceth-7 do in a cosmetic formula?
This ingredient is a nonionic surfactant and solubilizer used to help disperse oils, fragrance components, and oily actives into water-based formulas. It can also support mild cleansing and emulsion stability.
Is Coceth-7 clean?
Clean-beauty frameworks often flag it because it is ethoxylated, with possible trace residuals such as 1,4-dioxane or ethylene oxide if purification is weak. Skin tolerance is generally good at typical cosmetic levels, but residue control is the main clean-standard issue.
Is Coceth-7 sustainable?
This material is made from plant-derived fatty alcohols reacted with a petrochemical epoxide, so its sourcing profile is mixed. It is generally biodegradable as a fatty alcohol ethoxylate, but it has less Green Chemistry alignment than simpler renewable surfactants.
Is Coceth-7 COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because ethoxylated materials fall outside the standard. Its biodegradability is a positive, but petrochemical input and ethoxylation chemistry limit its Green Chemistry fit.
How does Coceth-7 work chemically?
The molecule is a mixture of fatty alkyl ether chains with an average of about seven oxyethylene units, giving it water dispersibility and oil-solubilizing behavior. It is typically used around 0.5 to 5% for solubilizing or mild cleansing, is stable across ordinary cosmetic pH ranges, and can be paired with anionic or amphoteric surfactants to tune foam and clarity.
