PEG-5 Ethylhexanoate ●
TL;DR. This ingredient is used mainly as a solubilizer and emulsifying surfactant, helping oily materials disperse into water-based formulas. It can also add a light emollient feel in cleansers, makeup removers, and rinse-off products.
What does PEG-5 Ethylhexanoate do in a cosmetic formula?
This ingredient is used mainly as a solubilizer and emulsifying surfactant, helping oily materials disperse into water-based formulas. It can also add a light emollient feel in cleansers, makeup removers, and rinse-off products.
Is PEG-5 Ethylhexanoate clean?
From a clean-beauty perspective, this ingredient carries friction because it is made through ethoxylation, a process associated with trace residual impurities if purification is not well controlled. It is generally considered low-sensitizing in finished formulas, but many stricter standards do not favor this ingredient class.
Is PEG-5 Ethylhexanoate sustainable?
This material is synthetic and typically relies on petrochemical feedstocks, which weakens its sustainability profile compared with readily renewable alternatives. Its ester structure may support some biodegradation, but the ethoxylated portion and manufacturing route make it less aligned with low-impact formulation principles.
Is PEG-5 Ethylhexanoate COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic products because ethoxylated ingredients are excluded. From a Green Chemistry perspective, it has useful formulation efficiency, but the petrochemical sourcing and ethoxylation step are clear limitations.
How does PEG-5 Ethylhexanoate work chemically?
The molecule is an ethoxylated ester with a short oxyethylene chain and a branched C8 fatty acid residue, giving it both oil-compatible and water-compatible character. It is typically used at low single-digit percentages and is most useful in systems where mild solubilization, oil removal, or emulsification is needed.
