Hydroxypropyltrimonium Hyaluronate Best Film-Forming Agent Anti-Ageing Hydration Hydroxypropyltrimonium Hyaluronate at a glance Next-gen derivative of moisture magnet hyaluronic acid Strongly adheres to skin for instant + long-lasting hydration Supports key proteins and lipids required for a strong barrier Cationic charge resists water rinse-off Texture-smoothing film-forming properties minus a tacky finish Hydroxypropyltrimonium Hyaluronate description Hydroxypropyltrimonium hyaluronate is a novel derivative of hyaluronic acid. The arrangement and weight of the hyaluronic acid molecule was altered to give it a strong cationic (positive) charge. Opposites attract, and since skin’s surface is negative, hydroxypropyltrimonium hyaluronate clings to it, resisting rinse-off. As a result, this ingredient has long-lasting hydrating properties, even when used in products such as body wash and facial cleansers. This next-gen form of hyaluronic acid is clinically proven to boost skin’s hydration instantly and long-term. Additionally, its ability to spread and cling better to skin’s surface benefits its barrier, helping to prevent moisture loss and ensure skin stays plumped. Unlike standard hyaluronic acid, hydroxypropyltrimonium hyaluronate helps influence key proteins and lipids responsible for a strong barrier. The cling factor this form of hyaluronic has gives it excellent film-forming properties, but its smaller size and ability to distribute evenly over skin’s surface avoids a sticky, tacky finish. Use levels of hydroxypropyltrimonium hyaluronate in cosmetics is typically 0.1%. It may be combined with other forms of hyaluronic acid for multi-level hydration and barrier support.
