C20-40 Pareth-10 ●
TL;DR. This ingredient is a nonionic surfactant and emulsifier used to help oil and water mix, improve wetting, and stabilize creams, lotions, cleansers, and hair-care formulas. It can also support texture and dispersion of waxy or oily components.
What does C20-40 Pareth-10 do in a cosmetic formula?
This ingredient is a nonionic surfactant and emulsifier used to help oil and water mix, improve wetting, and stabilize creams, lotions, cleansers, and hair-care formulas. It can also support texture and dispersion of waxy or oily components.
Is C20-40 Pareth-10 clean?
From a clean-beauty perspective, it has friction because it is made through ethoxylation, a process associated with trace ethylene oxide and 1,4-dioxane residues if purification is not well controlled. It is generally mild in use, but many stricter clean standards flag or restrict this material class.
Is C20-40 Pareth-10 sustainable?
This material is typically based on synthetic long-chain alcohol chemistry with petrochemical processing inputs. The surfactant class is generally biodegradable, but the sourcing and manufacturing route are less aligned with renewable, minimal-processing preferences.
Is C20-40 Pareth-10 COSMOS-approved?
It is not permitted under COSMOS natural or organic standards because ethoxylated materials are outside the standard’s allowed chemistry. From a Green Chemistry view, it is functional and usually biodegradable, but its petrochemical processing route and residue-control needs weaken its alignment.
How does C20-40 Pareth-10 work chemically?
The molecule is a long-chain hydrophobe connected to an average of about 10 oxyethylene units, giving it nonionic surfactant behavior and compatibility across a broad pH range. It is commonly used at low single-digit percentages in emulsions and cleansing systems, and formulators typically manage purity specifications for residual ethoxylation byproducts.
