Hydrogenated Polycyclopentadiene ●
TL;DR. This ingredient is a synthetic film-forming resin that adds gloss, adhesion, water resistance, and structure in color cosmetics, lip products, and long-wear formats. It can also help bind pigments and stiffen wax or oil systems.
What does Hydrogenated Polycyclopentadiene do in a cosmetic formula?
This ingredient is a synthetic film-forming resin that adds gloss, adhesion, water resistance, and structure in color cosmetics, lip products, and long-wear formats. It can also help bind pigments and stiffen wax or oil systems.
Is Hydrogenated Polycyclopentadiene clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic, petroleum-derived polymer rather than a naturally derived or readily biodegradable material. It is generally low in skin reactivity, but its polymer status and persistence profile place it outside many stricter clean-standard preferences.
Is Hydrogenated Polycyclopentadiene sustainable?
This material is made from fossil-derived feedstocks and is not expected to readily biodegrade. Its main sustainability concern is environmental persistence, especially if used in formats that enter rinse-off or particulate waste streams.
Is Hydrogenated Polycyclopentadiene COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic petrochemical polymer. Its Green Chemistry fit is weak, with nonrenewable sourcing and limited biodegradability offsetting its useful stability and performance at low use levels.
How does Hydrogenated Polycyclopentadiene work chemically?
The molecule is a saturated hydrocarbon polymeric resin, which makes it highly hydrophobic, chemically inert, and resistant to oxidation compared with unsaturated resins. It is typically used in anhydrous or low-water systems, often around a few percent up to the low double digits, and it relies on compatible oils, waxes, or hydrocarbon solvents for dispersion and film formation.
