About

A synthetic hydrocarbon resin — used in some specialty cosmetic applications but has very limited safety data. One of those obscure ingredients you'll rarely encounter.

Hydrogenated Polycyclopentadiene is the hydrogenated homopolymer of 1,3-cyclopentadiene. It's a synthetic hydrocarbon resin that may function as a film-former or depilatory agent in cosmetic formulations. CosIng lists a depilatory function. No CAS number is assigned, no GHS hazards are flagged, and no EU restrictions apply beyond a generic ozone-depletion ban (likely a database artifact). Very limited cosmetic-specific safety data exists for this ingredient, making a definitive safety assessment difficult. The hydrogenation step generally improves stability and reduces reactivity compared to unsaturated precursors.
