Description

Ethyldimethyl(Octadecyl)Ammonium Ethyl Sulphate is a quaternary ammonium compound (quat) with a long C18 alkyl chain, functioning as a cationic surfactant. This chemical matters for its potent antimicrobial, antistatic, and softening properties, making it a versatile active ingredient in industrial and consumer formulations. It is primarily needed by manufacturers in the personal care, textile, and industrial biocides sectors for creating effective and stable end products.

Application

• As an active ingredient in fabric softeners and conditioners to impart softness and reduce static cling.
• As a conditioning agent in hair care products (e.g., conditioners, creams) for detangling and smoothness.
• As a component in cationic emulsifiers for cosmetic and pharmaceutical creams and lotions.
• As a biocide and disinfectant in industrial cleaning and sanitizing formulations.
• As an antistatic agent in plastics, textiles, and electronics manufacturing processes.
• As a phase transfer catalyst in organic synthesis reactions.
• In the paper industry as a softening and debonding agent for tissue products.
• As an additive in agricultural adjuvants to enhance the efficacy of pesticide formulations.
