PPG-26-Buteth-26 ●
TL;DR. This ingredient is primarily a solubilizer and nonionic surfactant, helping dissolve fragrance oils and oily components into water-based formulas. It can also support clarity and stability in sprays, cleansers, and gels.
What does PPG-26-Buteth-26 do in a cosmetic formula?
This ingredient is primarily a solubilizer and nonionic surfactant, helping dissolve fragrance oils and oily components into water-based formulas. It can also support clarity and stability in sprays, cleansers, and gels.
Is PPG-26-Buteth-26 clean?
From a clean-beauty perspective, this material has friction because it is an alkoxylated synthetic and may require tight controls for residual ethylene oxide and 1,4-dioxane. It is not a common high-irritation ingredient, but its manufacturing route places it on many stricter restricted lists.
Is PPG-26-Buteth-26 sustainable?
This material is typically petroleum-derived and made through synthetic ether chemistry rather than renewable, low-impact processing. Its polyether structure can be slower to biodegrade than simpler plant-derived surfactants, which weakens its environmental profile.
Is PPG-26-Buteth-26 COSMOS-approved?
It is generally not permitted under COSMOS organic or natural standards because it is a synthetic alkoxylated material made using petrochemical oxide chemistry. Its Green Chemistry fit is limited by nonrenewable feedstocks, residue-management needs, and less favorable biodegradability.
How does PPG-26-Buteth-26 work chemically?
The molecule is a nonionic polyether built from butyl alcohol with propoxylated and ethoxylated chain segments, giving it both oil-compatible and water-compatible character. It is used at low levels as a solubilizer in many leave-on and rinse-off products, is broadly stable across typical cosmetic pH ranges, and often performs best when paired with other nonionic solubilizers.
