Other ingredient
Hydrogenated Rosin
Hydrogenated Rosin is produced by catalytic hydrogenation of natural colophony (pine rosin), a complex mixture of diterpene resin acids dominated by abietic acid. Hydrogenation saturates the double bonds in the resin acids, significantly improving oxidative stability, reducing yellowing, and decreasing the allergenic abietic acid content. In cosmetics it is used as a film-former and viscosity modifier. EU Cosmetics Regulation includes colophony derivatives among monitored potential allergens, though the hydrogenated form is substantially safer than natural rosin.
Also known as: hydrogenated colophony, hydrogenated pine rosin

Benefits
- ✓Hydrogenated form of colophony (pine rosin) with improved stability and reduced allergenic potential compared to natural rosin — functions as a film-former and adhesion promoter
- ✓Creates a lightweight, flexible film on skin that improves texture and supports ingredient delivery in premium emulsion formulas
- ✓Well-tolerated at cosmetic use concentrations; the hydrogenation process significantly reduces the abietic acid content responsible for contact sensitization in natural rosin
Watch for
- ⚠Natural rosin (colophony) is a known contact allergen (INCI 'Rosin'); hydrogenation reduces but may not eliminate sensitization potential — individuals with known rosin/colophony allergy should exercise caution
- ⚠EU Cosmetics Regulation lists rosin and some derivatives as potential sensitizers; hydrogenated rosin is considered significantly safer but caution advised for sensitized individuals
Compatibility
✓ Works well with
+ Dimethicone+ Jojoba Esters+ Squalane
