Alkylpolyethoxy Carboxylates (AEC)

Alkylpolyethoxy carboxylates(AEC)
Introduction and properties:
Alkylpolyethoxy carboxylates (AEC) are a new type of multifunctional anionic-surfactants. The technology of AEC preparation is one of the national key projects developed by China Research Institute of Daily Chemical Industry (RIDCI). The general structure of AEC is confirmed to be R-(OCH2CH2)n-OCH2COONa, which is similar to soaps. AEC exhibit nonionic properties at low pHs due to a poly-ethoxy group being inserted between the fatty chain and the carboxylic group of soaps. AEC can be used in a wide pH range.
1. Good detergency, emulsifying, dispersability and lime soap dispersability.
2. High foam power and foam stability.
3. Acid and alkaline stability, hard-water tolerance, high temperature resistance, oxidants and reductants resistance.
4. Compatibility with general surfactants, especially cationic surfactants.
5. Superior hydrotroping, usage in the preparation of functional transparent products.
6. Non-toxic, non-irritating, and readily biodegradability.
Applications
1. Emulsifying agents in paste cosmetic products.
2. Personal care products of mild shampoos, bubble baths, cream rinses, hand-cleaning gels etc.
3. Incorporated into soaps to improve mildness, lime soap dispersability, foam properties.
4. Applications in household detergents? Industrial cleaning and non-phosphorus detergents.
5. Applications in scouring, mercerization, bleaching, softening, dyeing process of textile industry.
6. Applications in EOR and oil transportation as emulsifying agents and viscosity reducer with resistance to high temperature and high concentrations of electrolytes.
7. Applications in deinking and softening agents of paper industry.
8. Degreasers in leather industry.
9. Applications in foam fire extinguisher as foam boosters.
