What it is
Hydrogenated Methyl Abietate is the hydrogenated methyl ester of abietic acid, a resin acid derived from pine rosin. Hydrogenation improves its color and stability, and the resulting tacky resin is used as a film former and binder that helps pigments and other ingredients adhere to skin and gives a smooth, cohesive feel. It is common in long-wearing color cosmetics and tinted sunscreens.
Safety & warnings
Because it is a rosin-derived material, individuals with a known colophony (rosin) allergy may potentially react, though hydrogenation reduces the reactive constituents associated with rosin sensitization. For most users it is well tolerated as a film former. It is not classified among the standard fragrance allergens.
Origin & sourcing
Derived from natural pine rosin (colophony); the abietic acid is esterified with methanol and then hydrogenated to improve stability.
Questions everyone asks
What is hydrogenated methyl abietate made from?
It is made from pine rosin: abietic acid from the rosin is turned into its methyl ester and then hydrogenated for better stability and color.
Should people with a rosin allergy be cautious?
Those with a known colophony (rosin) allergy may want to be cautious, although hydrogenation lowers the reactive components linked to rosin sensitivity.
