Pure inert polymer without notable comedogenicity. Suits sensitive skin, reactions are isolated.
Hydrogenated Polyisobutene is a synthetic liquid hydrocarbon, isobutylene polymer that has been hydrogenated. Transparent oily liquid, chemically inert. Where applied. Substitute for mineral oil and squalane in creams, lotions, lipsticks, mascaras. Provides light slip, a thin flexible film, and water resistance for color cosmetics. Often used in long-wear lipsticks, lip tints, water-resistant sunscreens, stretch mark products. In Spain in Bioderma Sensibio Light, Sesderma Acglicolic, Isdin water-resistant sunscreens. Safety. CIR rated hydrogenated polyisobutene safe at current cosmetic concentrations (2009, re-evaluated 2018). Non-irritating, non-sensitizing, non-comedogenic. Pregnancy and lactation – safe topically. Suitable for all skin types. In some patients with very sensitive skin synthetic hydrocarbons produce a "greenhouse" effect from pronounced occlusion – prefer more "breathable" emollients then (squalane, esters).
