Tetradonium Bromide丨CAS 1119-97-7

Tetradonium Bromide丨CAS 1119-97-7 is a quaternary ammonium salt featuring two pyrrolidinium cations tethered by a decamethylene chain and counterbalanced by two bromide anions. As a cationic surfactant, it is known for its antimicrobial, antistatic, and surface-active properties, making it particularly valuable in cosmetics, hair care formulations, antiseptic applications, and specialty industrial uses.
Its molecular structure provides enhanced surface adsorption, hydrophobic interaction, and broad-spectrum biocidal activity, positioning it as a functional agent in multiple industries.

1. Hair Care and Cosmetic Industry
a. Conditioning Agent
● Used in conditioners, shampoos, and styling products to enhance hair smoothness and manageability.
● Its cationic nature allows it to bind to negatively charged hair fibers, reducing static and frizz.
b. Emulsifier and Thickener
● Functions as a co-emulsifier in formulations containing oils and silicones.
● Contributes to the creaminess and stability of products like leave-in conditioners and moisturizers.
c. Antistatic Agent
● Reduces electrostatic buildup on hair and skin, improving texture and user experience.

2. Antimicrobial and Antiseptic Applications
● Quaternary ammonium compounds like Tetradonium Bromide丨CAS 1119-97-7 exhibit strong antimicrobial activity, effective against:
oGram-positive and Gram-negative bacteria
oFungi and yeasts
● Applied in disinfectant products, preservatives, and topical antiseptics, especially in personal care formulations to:
oPrevent microbial contamination
oEnhance product safety and shelf life

3. Oral Care Products
● Sometimes used in mouthwashes or oral rinses for its antibacterial properties, helping reduce plaque formation and bad breath.
● Its surfactant action can also aid in dispersing debris and residues in the oral cavity.

4. Industrial and Surface Care Applications
● Employed in hard surface disinfectants, especially in healthcare, veterinary, and food-processing environments, where potent and stable biocides are required.
● Serves as a surface conditioner and antimicrobial additive in cleaning products, sanitizers, and fabric treatments.

5. Emulsification and Surfactant Uses
● Functions as a cationic surfactant, useful in the formulation of emulsions, suspensions, and dispersions.
● Enhances the mixing of immiscible phases, such as oil and water, in both cosmetic and industrial applications.

✅ Effective Conditioning Performance
● As a cationic compound, it neutralizes negative charges on hair and skin surfaces, leaving them smooth and less prone to tangling or static.
✅ Broad-Spectrum Antimicrobial Activity
● Proven to combat a wide range of microorganisms, helping maintain product integrity and hygiene, especially in multi-use products.
✅ Stability in Formulations
● Chemically stable under various pH conditions and temperatures, making it suitable for long-lasting formulations.
✅ Surfactant and Emulsifying Properties
● Acts as a functional surfactant that improves formulation texture, spreadability, and active ingredient delivery.
✅ Mild and Non-Irritating in Low Concentrations
● When used at recommended concentrations, it has a low irritation profile, supporting its use in leave-on cosmetic formulations.

Formulation Considerations
● Recommended Usage Levels: Typically ranges from 0.1% to 1.0% depending on the application (e.g., conditioners, emulsions, sanitizers).
● pH Range: Compatible with mildly acidic to neutral systems (ideal pH ~4.5–7.0).
● Compatibility: Works well with other cationic and nonionic ingredients, but may be incompatible with strong anionic surfactants due to charge interactions.

Conclusion
Tetradonium Bromide丨CAS 1119-97-7 is a multifunctional cationic compound widely used in personal care, hygiene, and antimicrobial applications. Its unique structure allows it to function as a conditioning agent, surfactant, and antimicrobial, providing both functional performance and formulation versatility.
