Description

(Carboxymethyl)Dimethyl-3-[(1-Oxooctadecyl)Amino]Propylammonium Hydroxide is a specialized quaternary ammonium compound with a long-chain fatty acid amide group, functioning as a cationic surfactant and conditioning agent. This unique structure provides excellent substantivity to surfaces, particularly hair and skin, offering superior softening and antistatic properties. It is a critical ingredient for manufacturers in the personal care and cosmetic industries seeking to formulate high-performance hair conditioners, skin creams, and other rinse-off or leave-on products that require effective conditioning and manageability.

Application

• Hair Care Formulations: A primary conditioning agent in shampoos, conditioners, hair masks, and leave-in treatments to impart softness, shine, and detangling properties.
• Skin Care Products: Used in body lotions, facial creams, and shaving preparations to provide a smooth, silky after-feel and improve skin moisturization.
• Cosmetic Additive: Functions as an emulsifier and antistatic agent in various cosmetic products, enhancing texture and application.
• Textile Softeners: Employed as a key cationic component in fabric softeners and laundry rinse aids to soften fabrics and reduce static cling.
• Industrial Surfactant: Serves as a specialty surfactant in applications requiring cationic surface activity, such as in certain emulsion systems or as a corrosion inhibitor additive.
