Isononyl Isononanoate ●
TL;DR. This ingredient is a lightweight emollient that gives creams, lotions, makeup, and sunscreens a dry, silky slip. It helps pigments and UV filters spread evenly and can soften the feel of heavier oils or waxes.
What does Isononyl Isononanoate do in a cosmetic formula?
This ingredient is a lightweight emollient that gives creams, lotions, makeup, and sunscreens a dry, silky slip. It helps pigments and UV filters spread evenly and can soften the feel of heavier oils or waxes.
Is Isononyl Isononanoate clean?
This ingredient is generally low-sensitizing and not a common allergen, so most clean frameworks treat it as a lower-concern synthetic emollient. The main clean-beauty friction is its petrochemical origin and limited fit with natural-standard rules.
Is Isononyl Isononanoate sustainable?
This material is typically made from petrochemical-derived feedstocks rather than renewable plant oils. It is expected to biodegrade more readily than silicones or fluorinated film formers, but its branched structure and fossil sourcing weaken its sustainability profile.
Is Isononyl Isononanoate COSMOS-approved?
This ingredient is generally not permitted under COSMOS-organic or COSMOS-natural because it is a synthetic ester usually derived from non-renewable feedstocks. From a Green Chemistry perspective, it scores well on low irritation and functional efficiency, but less well on renewable sourcing and natural-standard compatibility.
How does Isononyl Isononanoate work chemically?
The molecule is a branched aliphatic ester, which explains its low-grease sensory profile, good spreadability, and compatibility with many oils, waxes, pigments, and organic UV filters. It is typically used as an emollient or dispersing medium at low single-digit to mid-range percentages, and it is most stable in neutral to mildly acidic or mildly alkaline formulas where ester hydrolysis is limited.
