Hydroxypropyl Starch Phosphate

Product Description

Our Hydroxypropyl Starch Phosphate is a premium, plant-derived modified starch manufactured as a high-performance rheology modifier for the global personal care market. This non-ionic ingredient is engineered to provide exceptional emulsion stability and viscosity control while imparting a unique, velvety skin feel that eliminates the tackiness often associated with synthetic polymers. As formulators shift towards sustainable and "clean beauty" standards, this biodegradable texturizer offers a robust solution for creating elegant, high-viscosity formulations without compromising on sensory appeal.

Key Benefits & Applications

• Instant Thickening & Stabilization: Rapidly builds viscosity in aqueous systems and provides excellent long-term stability for O/W emulsions.
• Superior Sensory Profile: Delivers a smooth, non-greasy, and "powdery" after-feel, making it an ideal alternative to traditional carbomers.
• Salt & pH Tolerance: Maintains consistent rheological properties in the presence of electrolytes and functions effectively across a wide pH range (3.0-10.0).
• Physical Sunscreen Booster: Helps in the uniform dispersion of inorganic filters like Zinc Oxide and Titanium Dioxide, preventing agglomeration.
• Broad Application: Extensively used in anti-aging creams, sunscreens, hair styling mousses, and color cosmetics.

Formulation Guidelines

• Recommended Dosage: 1.0% – 7.0% (typical usage is 3-5% for cream textures).
• Processing Method: Can be dispersed in either the oil or water phase. For optimal results, add to the water phase under high shear and heat to 70-75°C to ensure full hydration.
• Compatibility: Compatible with most anionic, cationic, and non-ionic surfactants and active ingredients.
• Synergy: Combine with Squalane to deliver high-performance emolliency and weightless shine, providing a sustainable, plant-based alternative to traditional silicones.
