Eastman launches Esmeri SK1N10 biodegradable micropowder for skin and sun care

Eastman launched Esmeri SK1N10, a readily biodegradable, non-nano cellulose ester micropowder for skin care and sun care, from its Kingsport, Tennessee base. The ingredient is designed for aqueous and oil-in-water systems and can boost SPF through UV scattering, potentially reducing UV-filter concentrations. Eastman's survey of 150 R&D professionals found only 52% satisfied with current biodegradable market offerings, and nearly half expect biodegradability to become mainstream within two to five years.

Key facts

Market context

Cellulose esters are derivatives of cellulose, a plant-based polymer, and are widely used in coatings, plastics, films and personal care. In cosmetics, fine powders are added to creams, lotions and sprays for texture, matte finish and light-scattering effects. Demand is driven mainly by skin care and sun care brands seeking ingredients that perform well while meeting tighter scrutiny of persistent materials. Traditional powder options include synthetic polymers such as polymethyl methacrylate and nylon-12, along with mineral silica, and regulators in Europe are increasingly focused on synthetic polymer microparticles. A biodegradable alternative that can support UV scattering in both water-based and oil-based formulas could give formulators more room to adjust costs, performance and UV-filter levels. For suppliers, this kind of product shifts competition toward sustainability credentials and application support rather than commodity pricing alone.
