Isopentane ●
TL;DR. This ingredient is used mainly as a volatile solvent, aerosol propellant, and quick-dry carrier in sprays, mousses, and some nail or hair products. It helps product spread, foam, or dispense, then evaporates rapidly with little residue.
What does Isopentane do in a cosmetic formula?
This ingredient is used mainly as a volatile solvent, aerosol propellant, and quick-dry carrier in sprays, mousses, and some nail or hair products. It helps product spread, foam, or dispense, then evaporates rapidly with little residue.
Is Isopentane clean?
From a clean-beauty perspective, this ingredient has friction because it is a petroleum-derived volatile organic compound rather than a skin-benefit material. It is generally low-irritation on skin at cosmetic exposure levels, but aerosol inhalation, flammability controls, and restricted-list positioning make it less aligned with many clean standards.
Is Isopentane sustainable?
This material is typically sourced from fossil feedstocks and releases volatile organic compounds during use. It does not tend to persist in water or soil, but its rapid evaporation and contribution to air-quality chemistry are the main sustainability concerns.
Is Isopentane COSMOS-approved?
This ingredient is not permitted in COSMOS-natural or COSMOS-organic formulations because it is a petrochemical volatile solvent or propellant. It has weak Green Chemistry alignment due to fossil sourcing, high volatility, and limited renewability, even though it evaporates readily and does not leave a persistent film.
How does Isopentane work chemically?
The molecule is a branched C5 saturated hydrocarbon with very low polarity, high vapor pressure, and a boiling point around 28 °C, which explains its fast flash-off and dry feel. It is most relevant in anhydrous or aerosol systems, needs pressure-rated and flame-controlled manufacturing, and has limited compatibility with highly polar water-based formulas unless supported by emulsifiers or co-solvents.
