C8-9 ISOPARAFFIN ●
TL;DR. This ingredient functions mainly as a lightweight, fast-evaporating solvent and carrier. It helps dissolve or disperse oils, waxes, pigments, and film-forming materials while leaving a less greasy finish.
What does C8-9 ISOPARAFFIN do in a cosmetic formula?
This ingredient functions mainly as a lightweight, fast-evaporating solvent and carrier. It helps dissolve or disperse oils, waxes, pigments, and film-forming materials while leaving a less greasy finish.
Is C8-9 ISOPARAFFIN clean?
From a clean-beauty perspective, this ingredient has friction because it is petroleum-derived and volatile. Skin tolerance is generally acceptable in finished products, but its vapors can be drying or irritating for some users in high-exposure formats.
Is C8-9 ISOPARAFFIN sustainable?
This material is sourced from non-renewable petroleum refining streams. Its small molecules are volatile and can contribute to solvent emissions, although they are expected to break down more readily than heavier, more persistent hydrocarbon materials.
Is C8-9 ISOPARAFFIN COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because it is a petrochemical hydrocarbon solvent rather than an approved natural, nature-derived, or allowed synthetic input. Its Green Chemistry fit is weak on renewable sourcing and solvent emissions, even if aerobic biodegradation is plausible for this carbon range.
How does C8-9 ISOPARAFFIN work chemically?
This material is a narrow mixture of small, branched, fully saturated molecules with eight to nine carbons, giving low polarity, very low water solubility, and high compatibility with oils, waxes, and resinous film formers. It is chemically stable across normal cosmetic pH because it has no hydrolysable or ionizable groups, and use levels vary widely from minor carrier amounts to a substantial solvent phase in anhydrous formats.
