Question 1

What does and nourish skin. GRACE: Isododecane do in a cosmetic formula?

Accepted Answer

This ingredient is a volatile solvent and carrier that gives makeup, sunscreen, and hair products a fast-drying, lightweight feel. It also helps disperse pigments, film-formers, and oil-soluble ingredients in long-wear formulas.

Question 2

Is and nourish skin. GRACE: Isododecane clean?

Accepted Answer

Clean frameworks often flag it because it is a petrochemical, volatile solvent with limited skin-care value beyond texture and dry-down. It is generally low in sensitization potential at cosmetic use levels, but high-solvent formulas can feel drying on some skin.

Question 3

Is and nourish skin. GRACE: Isododecane sustainable?

Accepted Answer

This material is commonly made from petroleum-derived feedstocks and is not a renewable ingredient. Its volatility contributes to solvent emissions during manufacture and use, and its end-of-life profile is less aligned with readily biodegradable plant-based materials.

Question 4

Is and nourish skin. GRACE: Isododecane COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS organic or natural standards because it is a synthetic petrochemical solvent. From a Green Chemistry view, it scores poorly on renewable sourcing and end-of-life fit, even though it can reduce greasiness and support anhydrous formats.

Question 5

How does and nourish skin. GRACE: Isododecane work chemically?

Accepted Answer

The molecule is a highly branched C12 alkane, which makes it nonpolar, low-viscosity, and fast-evaporating compared with heavier emollient oils. It is typically used in the low single digits up to around 20% in long-wear color cosmetics and sunscreens, and it is chemically stable across normal cosmetic pH because it does not meaningfully ionize in water.
