Chemical Description

  • Cetyltrimethylammonium chloride is a white crystalline powder that is soluble in water. It produces a large amount of foam when shaken and has good compatibility with cationic, nonionic, and amphoteric surfactants. Good chemical stability, heat resistance, light resistance, pressure resistance, strong acid and alkali resistance; excellent penetration, softening, emulsification, antistatic, biodegradability, and other properties.
  • CTAC operates stealthily as a surfactant and conditioner. Its addition to shampoos, conditioners, body washes, and hair styling products ensures thorough cleansing and imbues hair with softness and manageability. Additionally, CTAC lends its antimicrobial prowess to mouthwashes and dental products, effectively combating plaque and gingivitis.
  • CTAC discreetly assumes roles as a surfactant, emulsifier, and preservative. It's a common ingredient in topical medications like creams and lotions, enhancing their texture and stability. Furthermore, its antimicrobial properties bolster the efficacy of antiseptic solutions and wound dressings, all while remaining inconspicuous.
  • CTAC covertly aids in the formulation of pesticides, herbicides, and fungicides as an emulsifying agent and adjuvant. Its presence ensures optimal dispersion and stability of active ingredients, thereby boosting the effectiveness of agricultural chemicals without drawing attention to themselves.
  • Acts as a fabric softener and antistatic agent in laundry detergents and fabric conditioners. It mitigates static cling and imparts a soft touch to fabrics, all without leaving a trace of its involvement.
  • CTAC operates surreptitiously as a corrosion inhibitor and demulsified. It shields metal surfaces from corrosion while facilitating the separation of water from oil and gas emulsions, ensuring smooth operations without raising any alarms.
  • Cetyltrimethylammonium chloride is utilized as a retention aid and sizing agent in papermaking processes. It helps to improve the retention of fine particles and fillers in paper pulp, resulting in enhanced paper strength, brightness, and printability. CTAC also acts as a surface sizing agent, reducing paper absorbency and improving ink holdout and print quality.
