Description

(2-Hydroxyethyl)Dimethyl[3-[(1-Oxooctadecyl)Amino]Propyl]Ammonium Chloride is a quaternary ammonium compound with a long-chain fatty amide group, functioning as a cationic surfactant and conditioning agent. This structure is critical for providing excellent substantivity to surfaces, particularly hair and skin, offering superior softening and antistatic properties. It is primarily needed by manufacturers in the personal care, cosmetic, and textile industries for formulating high-performance conditioners, hair treatments, and fabric softeners.

Application

• Hair Care Formulations: A key cationic conditioning agent in shampoos, conditioners, and hair masks for detangling, smoothness, and manageability.
• Skin Care & Cosmetics: Used in creams, lotions, and shaving products to provide a soft, smooth after-feel and improve product spreadability.
• Textile Softening: Acts as a primary active ingredient in liquid and concentrated fabric softeners for household and industrial laundry applications.
• Industrial Surfactant: Employed as an emulsifier, dispersant, or antistatic agent in various specialty chemical and industrial cleaning formulations.
• Pharmaceutical Aids: Can be utilized in topical pharmaceutical preparations for its emollient and delivery-enhancing properties.
