Pentaerythrityl Hydrogenated Rosinate

What is Pentaerythrityl Hydrogenated Rosinate?

Pentaerythrityl Hydrogenated Rosinate is a tetraester formed by reacting pentaerythritol with hydrogenated rosin acids, sourced from the resin of pine trees. Hydrogenation process stabilizes the molecule by removing unsaturation, preventing rancidity and yellowing. Commonly found in color cosmetics such as lipsticks, mascaras, eyeliners, and nail products. It imparts tackiness that binds pigments and waxes, thickens formulations for even application and suspension of particles, and deposits a sheer, flexible sheath on skin or lashes to boost durability against rubbing or moisture without stiffness.
