Hydroxypropyl Guar

Product Description

Our Hydroxypropyl Guar is a high-purity, non-ionic polymer derived from natural guar gum, specifically engineered in our ISO-certified facility for premium cosmetic applications. By modifying the natural guar structure through propoxylation, this ingredient offers superior water solubility and clarity compared to native gum, acting as a versatile rheology modifier and film-forming agent. As the global B2B market increasingly demands sustainable and bio-based ingredients, our Hydroxypropyl Guar provides a robust solution for achieving stable viscosity and a luxurious, smooth skin feel in both leave-on and rinse-off formulations.

Product Specification

Key Benefits & Applications

• Rheology Enhancement: Efficiently thickens aqueous systems, providing excellent shear-thinning flow properties for sprays and pumps.
• Film-Forming Effect: Creates a protective, breathable film on the skin and hair, reducing moisture loss and improving tactile smoothness.
• Non-Ionic Compatibility: Its non-ionic nature ensures exceptional stability in formulas with high salt content or varying electrolyte concentrations.
• Improved Clarity: Offers significantly higher transparency in solutions compared to standard guar gum, ideal for clear gel formulations.
• Multi-Sector Use: Essential for hydrating serums, transparent shampoos, shaving foams, and high-performance body lotions.

Formulation Guidelines

• Recommended Dosage: 0.2% – 1.5% for typical formulations; up to 2.0% for high-viscosity styling gels.
• Processing: Disperse in the water phase with rapid stirring. Adjusting the pH to a slightly acidic range (approx. 5.5 - 6.0) will facilitate rapid swelling and full viscosity development.
• Thermal Stability: Heat-stable polymer, allowing for addition during either hot or cold processing phases.
• Synergy: Combine with Bisabolol to soothe scalp irritation and enhance the anti-inflammatory properties of the formulation, creating a calming experience for sensitive skin.
