Fatty alcohol polyether-n carboxylate salt is a type of anionic surfactant synthesized through the ethoxylation of fatty alcohols followed by carboxylation to introduce a salt group. This chemical modification results in a molecule with both hydrophobic (fatty alcohol) and hydrophilic (polyether carboxylate salt) segments, granting it surface-active properties [1]. The ethoxylation degree (n) can be adjusted to fine-tune the surfactant's hydrophilic-lipophilic balance (HLB), impacting its emulsification, foaming, and detergency characteristics.

The production process typically involves reacting a fatty alcohol with ethylene oxide in the presence of a catalyst to form a fatty alcohol polyether [2]. This intermediate then undergoes carboxylation, often using chloroacetic acid or its salt, followed by neutralization to form the carboxylate salt [3]. The final product is then purified and standardized based on the desired specifications, such as active matter content and pH.

As a surfactant, fatty alcohol polyether-n carboxylate salt exhibits several beneficial properties, including emulsification, solubilization, and detergency [4]. It can reduce surface tension, allowing for the formation of stable emulsions and the removal of oily dirt from surfaces. Its mildness and good compatibility with other ingredients make it suitable for various cosmetic and personal care applications.

Fatty alcohol polyether-n carboxylate salt finds use in a range of personal care and cleaning products. It can be found in shampoos, body washes, and facial cleansers, where it contributes to foaming and cleaning performance [5]. It is also used in liquid soaps and detergents as a primary or secondary surfactant. In some formulations, it functions as an emulsifier to stabilize oil-in-water emulsions, improving product texture and stability.

Fatty alcohol polyether-n carboxylate salts are generally packaged in drums, IBCs (intermediate bulk containers), or smaller containers depending on the quantity and customer requirements. During transportation, these containers should be kept sealed and protected from extreme temperatures to maintain product quality [6]. Standard safety precautions, such as wearing gloves and eye protection, should be observed when handling the product to prevent skin or eye irritation.
