Beheneth-25 ●
TL;DR. This ingredient is a nonionic emulsifier and solubilizer, used to help oil and water phases combine and to keep creams, lotions, and cleansers uniform. It can also improve texture and aid dispersion of oils, waxes, and fragrance components.
What does Beheneth-25 do in a cosmetic formula?
This ingredient is a nonionic emulsifier and solubilizer, used to help oil and water phases combine and to keep creams, lotions, and cleansers uniform. It can also improve texture and aid dispersion of oils, waxes, and fragrance components.
Is Beheneth-25 clean?
From a clean-beauty perspective, it has friction because it is made through ethoxylation, a process that can leave trace processing residues if not tightly purified. Skin tolerance is generally good, but many stricter standards scrutinize this material category rather than the finished safety profile alone.
Is Beheneth-25 sustainable?
This material is partly based on a long-chain fatty alcohol that may come from plant or petrochemical sources, while the added water-loving chain is typically petrochemical-derived. It is expected to biodegrade better than persistent silicones, but its synthetic processing and feedstock traceability weaken its sustainability profile.
Is Beheneth-25 COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic because ethoxylated materials are generally outside the standard’s allowed chemistry. From a Green Chemistry view, the main drawbacks are petrochemical input, added processing burden, and residue-control requirements, despite useful performance at low use levels.
How does Beheneth-25 work chemically?
The molecule is a nonionic surfactant built from a C22 hydrophobic tail attached to an average of about 25 oxyethylene units, giving it strong water-dispersing and emulsifying character. It is typically stable across normal cosmetic pH ranges and is used in low percentages as a co-emulsifier or solubilizing aid, with purification quality important for controlling trace residuals.
