Sodium Hyaluronate Crosspolymer 2
What is Sodium Hyaluronate Crosspolymer 2?
Sodium Hyaluronate Crosspolymer 2 is a highly advanced, crosslinked form of sodium hyaluronate, a salt derivative of hyaluronic acid, engineered through hydrogen bonding and dynamic covalent linkages to create a super-high molecular weight polymer. This innovative crosspolymer forms a stable, three-dimensional network capable of absorbing over 6,000 times its weight in water, providing exceptional long-lasting hydration that adheres firmly to the skin without dissolving quickly. It is widely used in skincare formulations for its superior moisture retention and skin-plumping effects compared to traditional hyaluronic acid variants.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Humectant
Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
