PEG-240/HDI Copolymer Bis-Decyltetradecet-20 Ether ●
TL;DR. This ingredient is a synthetic rheology modifier used to thicken water-based formulas and improve gel structure. It can also help suspend particles and stabilize emulsions by forming an associative polymer network.
What does PEG-240/HDI Copolymer Bis-Decyltetradecet-20 Ether do in a cosmetic formula?
This ingredient is a synthetic rheology modifier used to thicken water-based formulas and improve gel structure. It can also help suspend particles and stabilize emulsions by forming an associative polymer network.
Is PEG-240/HDI Copolymer Bis-Decyltetradecet-20 Ether clean?
From a clean-beauty perspective, it has friction because it is a synthetic ethoxylated polymer rather than a simple, naturally derived material. Finished material quality depends on tight control of residual processing impurities, and some clean standards restrict this class even when skin irritation potential is generally low.
Is PEG-240/HDI Copolymer Bis-Decyltetradecet-20 Ether sustainable?
This material is largely petrochemical-derived, with possible fatty-chain inputs from plant or petroleum sources depending on supplier. It is a high-molecular-weight water-soluble polymer with limited ready-biodegradability data, so its environmental profile is less favorable than readily biodegradable thickeners.
Is PEG-240/HDI Copolymer Bis-Decyltetradecet-20 Ether COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic standards because ethoxylated synthetic polymers are generally outside the allowed ingredient scope. Its Green Chemistry profile is compromised by nonrenewable feedstocks, multistep synthetic processing, and uncertain biodegradation behavior.
How does PEG-240/HDI Copolymer Bis-Decyltetradecet-20 Ether work chemically?
The molecule is an amphiphilic associative polyurethane-type polymer with hydrophilic polyether segments and hydrophobic end groups that build viscosity through transient network formation in water. It is typically used at low levels in aqueous systems, is most useful for clear gels and surfactant-containing formulas, and can be sensitive to electrolyte load, solvent level, and surfactant blend.
