Sodium polyacrylate plays the following roles in skincare products:
Thickener: Sodium polyacrylate can increase the viscosity and fluidity of skincare products, making them easier to use and apply to the skin. It can improve the texture and feel of the product, and enhance the user experience.
Humectant: Sodium polyacrylate has good moisturizing properties, which can adsorb and lock in moisture on the skin surface, forming a moisturizing film to prevent water loss. This helps to keep the skin hydrated and soft.
Stabilizer: sodium polyacrylate can help stabilize the emulsification system or dispersion system in skin care products, and prevent problems such as particle precipitation and phase separation in lotion or suspension. It can improve the stability and retention of the product.
Emulsifier: sodium polyacrylate can promote the mixing and emulsifying process of oil-water phase, help to evenly disperse oily ingredients and water-based ingredients together, and form a stable lotion skin care product.
Excipient: Sodium polyacrylate is used as an excipient in some skincare products, which can increase the viscoelasticity and viscosity of the product, making it easier to stay on the skin and form a film.
It should be noted that the usage of sodium polyacrylate should be controlled within a safe range, following relevant usage guidelines and regulatory requirements. For specific skincare formulas, it is recommended to consult professional cosmetic scientists or skin experts to ensure their safety and effectiveness.
