Cosmetic Grade Sodium Polyacrylate(CAS 9003-04-7)
Cosmetic-grade Sodium Polyacrylate is a high-efficiency water-soluble polymer thickening and gel-forming raw material specially used in the cosmetic industry. Compared with traditional thickeners such as carbomer, it has outstanding advantages of cold water solubility and neutralization-free thickening, which greatly simplifies the production process and improves production efficiency.
After rapid hydration in water, it can form a highly transparent, uniform and stable gel system with excellent shear thinning properties. The gel is thick under static state and fluid under stirring, which endows cosmetics with delicate texture and excellent pumping and spreading performance. It has super strong water-locking capacity, which can wrap a large amount of water molecules to form a moisturizing protective layer on the skin surface, effectively reduce transepidermal water loss, and provide long-lasting moisturizing effect without sticky and heavy feeling.
In addition, Sodium Polyacrylate has excellent suspension and stabilization functions, which can stably suspend fine particles, plant extracts and microcapsules in the formula, prevent precipitation and delamination, and significantly improve the stability and appearance grade of finished products. With mild and non-irritating properties, good skin affinity, no peculiar smell, and strong compatibility with various water-soluble functional ingredients, it is a versatile and cost-effective core thickening and stabilizing raw material for modern water-based cosmetic formulas.
Key Benefits
• Cold Water Soluble & Neutralization-Free: Fast hydration and thickening in cold water, no need for pH neutralization operation, simplify production process and save production cost.
• High Transparent Gel & Good Thixotropy: Forms crystal clear gel without flocculation and impurities, static thickening and dynamic fluidity, perfect texture for transparent cosmetic products.
• Super Strong Water-Locking & Refreshing Moisturizing: Wrap water molecules to build long-lasting moisturizing layer, effectively relieve dryness, non-sticky and non-greasy skin feel.
• Excellent Suspension & Stabilization Performance: Stably suspend functional particles and essence microcapsules, prevent formula delamination and precipitation, improve product stability.
• Mild & High Safety: Cosmetic high-purity purification, odorless and non-irritating, good skin affinity, suitable for sensitive skin and mild daily chemical formulas.
• Wide Compatibility & Strong Salt Resistance: Adaptable to various water-soluble ingredients and electrolyte systems, stable viscosity and no thinning in complex formulas.
Applications
• Transparent Skin Care Gel Series: Core thickening and gel-forming raw materials for transparent moisturizing gel, aloe vera gel, after-sun repair gel and soothing gel, creating high-transparency delicate texture.
• Moisturizing Skin Care Lotion & Cream: Used in hydrating essence, moisturizing lotion, facial cream and mask liquid to optimize product texture, improve water-locking moisturizing effect and enhance skin fitting.
• Daily Cleansing & Care Products: Added in shampoo, body wash, hand sanitizer and mild cleansing products to thicken and stabilize the system, improve product fluidity and appearance.
• Suspension Functional Formula: Suitable for particle-containing skincare products, plant extract formulas and microcapsule sustained-release systems to achieve uniform suspension and stable efficacy release.
• Mild Sensitive Skin Care Series: Applied in sensitive skin soothing and repairing products, with mild formula, low irritation and stable moisturizing and repairing effects.
