Hydroxypropyltrimonium Hydrolyzed Soy Protein

Product Description

Hydroxypropyltrimonium Hydrolyzed Soy Protein is a high-performance, plant-derived cationic protein active manufactured in our facility to meet the rising demand for vegan-friendly hair and skin care solutions. By modifying soy peptides with a quaternary ammonium functional group, this ingredient provides exceptional substantivity to damaged keratinous substrates, forming a protective biomimetic film. It offers significant commercial value for brands targeting the "Green Beauty" sector, providing a powerful vegetable-based alternative to animal-derived proteins without compromising on conditioning efficacy.

Key Benefits & Applications

• Vegetal Fiber Reinforcement: Penetrates the hair shaft to replenish lost protein mass, significantly increasing the tensile strength and elasticity of chemically treated hair.
• Substantive Hydration: The cationic charge anchors soy peptides to the skin and hair, preventing "wash-off" and ensuring long-lasting moisture retention.
• Frizz and Static Control: Efficiently neutralizes negative surface charges, smoothing the cuticle for improved manageability and a soft, natural touch.
• Volume and Body: Enhances hair diameter and provides structural body to fine or thinning hair without the heavy buildup associated with synthetic silicones.
• Applications: Perfect for vegan conditioners, fortifying shampoos, plant-based hair repair serums, and nourishing body lotions.

Formulation Guidelines

• Suggested Dosage: 1.0% – 5.0% depending on the desired repair level.
• pH Stability: Maintains peak performance and clarity between pH 4.0 and 7.0.
• Processing: Water-soluble; recommended to be incorporated during the cool-down phase (below 45°C) to maintain the bio-activity of the soy peptides.
• Compatibility: Shows excellent compatibility with cationic and non-ionic surfactants. In systems with high anionic surfactant loads, slow addition under stirring is advised.
• Synergy: Combine with Tocopherol (Vitamin E) to provide antioxidant protection against environmental stressors while maintaining the structural integrity of the soy protein film.
