Stearamidopropyl Dimethylamine

Product Description

As a premier direct factory supply ingredient, our High Purity Stearamidopropyl Dimethylamine offers exceptional quality and remains highly stable in aqueous solution for professional cosmetic manufacturing.

Operating as a high-performance amidoamine, it undergoes protonation in acidic environments to provide targeted electrostatic neutralization, adhering seamlessly to negatively charged keratin.

This optimal substantivity makes it a highly sought-after silicone alternative, meeting the growing market trend for lightweight, high-efficacy hair care formulations, while suggesting potential benefits for transdermal delivery in specialized skin emulsions.

Product Specification

• Product Name: Stearamidopropyl Dimethylamine
• Cas Number: 7651-02-7
• Chemical Class: Amidoamine
• Appearance: White to off-white flakes or pastilles
• Purity: ≥ 98.0%
• Melting Point: 65 - 70°C

Key Benefits & Applications

• Electrostatic Neutralization: Effectively mitigates triboelectric charging of the hair shaft, reducing flyaways and enhancing manageability.
• Keratin Substantivity: Provides targeted adsorption to cysteine-depleted, damaged structural sites on the hair cuticle without causing heavy buildup.
• Emulsification Efficacy: Functions as a robust primary or secondary emulsifier, remaining highly stable in aqueous solution when properly neutralized.
• Suggested Applications: Formulated extensively in professional hair masks, deep conditioners, and silicone-free detangling lotions.

Formulation Guidelines

• Neutralization Requirement: Must be neutralized with an organic acid (such as lactic acid or citric acid) at a stoichiometric ratio to achieve a formulation pH of 4.5 to 5.5 for optimal cationic activity.
• Processing Temperature: Heat the aqueous phase and the lipid phase to 75-80°C to ensure the complete melting and integration of the amidoamine structure.
• Phase Incorporation: Recommended to be added to the heated oil phase before emulsification to ensure uniform dispersion.
• Synergy: Combine with Cetearyl Alcohol for enhanced lamellar gel network formation and superior viscosity building.
