Applications of Aluminium Chlorohydrate丨CAS 12042-91-0
1. Personal Care & Cosmetics
a. Antiperspirants
● Primary ingredient in most commercial antiperspirant formulations (sprays, roll-ons, sticks, gels).
● Works by blocking sweat glands, reducing sweat and preventing odor-causing bacteria.
● Preferred due to its effectiveness, low irritation potential, and quick-drying properties.
b. Deodorants
● Inhibits bacterial growth that leads to body odor.
● Often used in combined antiperspirant-deodorant products.
2. Water Treatment
● Acts as a coagulant in drinking water and wastewater treatment.
● Helps to remove:
oSuspended solids
oOrganic matter
oPathogens
oHeavy metals
● Preferred for its low sludge production, higher floc density, and lower pH sensitivity compared to traditional coagulants like alum.
3. Industrial Applications
a. Paper Manufacturing
● Used in the sizing process to improve paper strength, resistance to ink, and moisture resistance.
● Helps in retention of fillers and fibers, improving overall paper quality.
b. Textile Industry
● Aluminium Chlorohydrate丨CAS 12042-91-0 acts as a mordant in dyeing processes, helping fix dyes to fabrics.
c. Catalyst & Reagent
● In chemical synthesis, it may be used as a Lewis acid catalyst in specialized reactions.
4. Pharmaceuticals and Dermatology
● Sometimes included in medicated topical formulations for its astringent and antiperspirant properties.
● Used in treatment of hyperhidrosis (excessive sweating) in higher-concentration products under medical supervision.
Benefits of Aluminium Chlorohydrate丨CAS 12042-91-0
1. Highly Effective Antiperspirant
● Clinically proven to reduce perspiration significantly with low skin irritation.
● Provides long-lasting dryness, often for 24–48 hours.
2. Water Treatment Efficiency
● More effective than alum (aluminum sulfate) in lower doses.
● Produces denser flocs, leading to better clarification and filtration.
● Works over a wide pH range, offering flexibility in water treatment systems.
3. Safety and Stability
● Recognized as safe for topical use by global regulatory agencies when used within specified concentrations.
● Chemically stable in solution, allowing for easy formulation in liquid products.
4. Cost-Effective and Versatile
● Low cost compared to many specialized coagulants and antiperspirant agents.
● Adaptable across multiple industries-from personal care to municipal water treatment.
Conclusion
Aluminium Chlorohydrate丨CAS 12042-91-0 is a multifunctional compound known for its efficacy as an antiperspirant agent and water treatment coagulant. Its broad application range spans personal care, environmental management, textile processing, and industrial manufacturing. With proven effectiveness, cost efficiency, and a strong safety profile, aluminium chlorohydrate remains a critical ingredient in daily-use consumer products and essential municipal and industrial processes.
