Pentaerythrityl Rosinate
Pentaerythrityl Rosinate is a plant-derived resin used in UK beauty products as a film-forming agent, thickener and skin-conditioning ingredient. It helps create long-wearing lipsticks, mascaras and eyeliners that stay put without cracking or flaking. Gentle and non-irritating, it is commonly found in clean-beauty and natural-leaning formulas.
How it works in skincare
In cosmetics and skincare, Pentaerythrityl Rosinate functions as an excellent film former and viscosity-increasing agent. It creates a flexible, breathable layer on the skin or lips that improves wear time and helps pigments adhere evenly. Derived from rosin, it also lends a subtle tackiness that enhances texture and prevents formulas from separating, making it especially useful in lipsticks, lip glosses, mascaras and long-wear eye products.
