Hydroxypropyltrimonium Hydrolyzed Rice Bran Protein

Hydroxypropyltrimonium Hydrolyzed Rice Bran Protein is a specialized cationic active derived from nutrient-rich rice bran, manufactured in our facility to offer a sustainable, plant-based solution for professional hair and skin care. Through advanced enzymolysis and cationization, this ingredient delivers high substantivity to negatively charged keratin surfaces, forming a protective, weightless film. It holds significant commercial value in the "Clean Beauty" market, particularly for formulations aiming to provide natural hair volume and soothing scalp benefits without the use of synthetic silicones.

Key Benefits & Applications

• Instant Volumizing Effect: Coats individual hair fibers with a substantive cationic layer, increasing the inter-fiber distance to provide noticeable body and "lift" to fine hair.
• Soothing Dermal Barrier: Contains rice-derived bioactive peptides that help soothe scalp irritation and reinforce the skin's natural barrier function.
• High Substantivity: The positive charge ensures that the conditioning benefits remain on the hair and skin even after rinsing, providing long-lasting softness and anti-static control.
• Moisture Balance: Regulates the water-binding capacity of the hair shaft, preventing dehydration caused by environmental exposure or heat styling.
• Applications: Highly recommended for volumizing shampoos, scalp-relief conditioners, vegan body washes, and lightweight hair thickening mists.

Formulation Guidelines

• Suggested Dosage: 1.0% – 5.0% depending on the desired volumizing intensity.
• pH Stability: Most stable and effective within a pH range of 4.5 – 7.0.
• Processing: Water-soluble active; should be added during the cool-down phase (below 45°C) to maintain the bio-activity of the rice bran peptides.
• Compatibility: Excellent compatibility with non-ionic and cationic systems. In anionic surfactant bases, ensure slow incorporation under stirring to maintain transparency.
• Synergy: Combine with Niacinamide for enhanced scalp barrier repair and improved hair root vitality.
