Sodium Hydroxypropyl Starch Phosphate

Product Description

Our Sodium Hydroxypropyl Starch Phosphate is a high-purity, plant-derived modified starch manufactured in our state-of-the-art facility to ensure consistent quality for global B2B supply. This multifunctional ingredient acts as a robust rheology modifier and emulsion stabilizer, utilizing its unique cross-linked structure to provide a non-tacky, velvety skin feel while maintaining formula viscosity across a wide pH range. As the industry pivots towards high-performance natural alternatives, this ingredient has become a market trend essential for creating sophisticated textures in premium skincare and suncare applications.

Key Benefits & Applications

• Rheology Modification: Provides excellent thickening properties and shear-thinning behavior for effortless spreadability.
• Emulsion Stabilization: Enhances the long-term stability of O/W emulsions by reducing oil droplet coalescence.
• Sensory Enhancement: Eliminates the greasiness of high-oil phase formulas, delivering a matte, powdery finish to the skin.
• Suncare Optimization: Ideal for stabilizing inorganic UV filters (Titanium Dioxide/Zinc Oxide) without compromising SPF performance.
• Application Versatility: Widely used in facial moisturizers, sunscreens, color cosmetics, and hair styling products.

Formulation Guidelines

• Recommended Usage: 1.0% – 5.0% depending on the desired viscosity and sensory profile.
• Processing: Can be added to the aqueous phase under high-speed agitation; it is stable to heat and does not require complex neutralization steps.
• pH Stability: Demonstrates superior stability within a pH range of 3.0 to 10.0, making it compatible with various acidic actives.
• Synergy: Combine with Squalane to deliver high-performance emolliency and weightless shine, providing a sustainable, plant-based alternative to traditional silicones.
