Polyisobutene and How Long a Formula Stays Put
This is a texture ingredient with a practical side effect. Polyisobutene is a synthetic emollient polymer that thickens a formula and forms a flexible, cohesive layer, which is part of how a sunscreen holds up to humidity and how a treatment serum stays in place under makeup.
Alastin uses it across its TriHex line: Restorative Skin Complex, Ultra Nourishing Moisturizer, Ultra Light Moisturizer and Restorative Neck Complex all contain it. EltaMD relies on it in UV Clear SPF 46 and UV Clear Tinted SPF 46.
Is polyisobutene heavy on the skin?
The amount used decides that. Alastin's Ultra Light Moisturizer and Ultra Nourishing Moisturizer both contain it and sit at opposite ends of the weight scale — a useful reminder that an ingredient list tells you less than a texture test.
