Hydroxypropyltrimonium Hydrolyzed Casein

Product Description

Hydroxypropyltrimonium Hydrolyzed Casein is a specialized cationic milk protein derivative produced in our advanced facility to harness the nutritional power of casein for high-end cosmetic applications. By grafting a quaternary ammonium group onto hydrolyzed casein peptides, we have created an ingredient with exceptional biological affinity and substantivity for both hair and skin. This active ingredient meets the growing market demand for "milk-based" luxury beauty products, providing formulators with a potent tool to deliver intense nourishment and a velvety sensory experience.

Product Specification

• INCI Name: Hydroxypropyltrimonium Hydrolyzed Casein
• CAS No.: 115043-46-2 (generic for protein trimoniums)
• Product Type: Cationic Protein / Milk Derivative
• Source: Bovine Milk Casein
• Molecular Weight: 1,500 - 3,000 Da
• Appearance: Clear to slightly amber liquid
• Purity (Protein Content): ≥ 20.0%
• Solubility: Soluble in water

Key Benefits & Applications

• High Substantivity: The cationic charge ensures the casein peptides remain anchored to the skin's keratin and hair fiber, providing long-lasting functional benefits even after rinsing.
• Intense Barrier Support: Rich in essential amino acids, it helps to reinforce the skin's natural moisturizing factor (NMF) and supports epidermal barrier repair.
• Structural Film-Forming: Creates a protective, non-occlusive film on the hair shaft, reducing moisture loss and protecting against environmental aggressors.
• Sensory Enhancement: Imparts a characteristic "milky" softness and smooth texture to formulations, improving the overall consumer application experience.
• Applications: Widely used in nourishing body washes, moisturizing facial cleansers, repair conditioners, and professional hair treatment ampoules.

Formulation Guidelines

• Suggested Dosage: 1.0% – 5.0% depending on the desired richness of the formulation.
• pH Stability: Best performance observed between pH 4.5 and 7.0.
• Processing: Water-soluble active; should be incorporated during the cool-down phase (below 45°C) to maintain the integrity of the peptide bonds.
• Compatibility: Excellent with cationic and non-ionic systems. In anionic-heavy formulations, it is recommended to add the ingredient slowly under high-speed stirring to prevent precipitation.
• Synergy: Combine with Panthenol (Pro-Vitamin B5) to repair hair cortex damage and seal in moisture with a protein-protective film.
