Sodium Hyaluronate Crosspolymer 4
What is Sodium Hyaluronate Crosspolymer 4?
Sodium Hyaluronate Crosspolymer 4 is a highly cross-linked form of sodium hyaluronate, the sodium salt of hyaluronic acid, engineered to create a super-high molecular weight polymer with exceptional water retention properties. This crosspolymer forms a stable, gel-like matrix that can hold up to 10 times more water than traditional hyaluronic acid, providing prolonged and intense hydration deep within the skin layers. It is commonly used in skincare formulations for its film-forming abilities and sustained moisture delivery.
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.
