Introduction

On March 1, 2023, China’s Ministry of Ecology and Environment issued the “List of Key Controlled New Pollutants (2023 Edition)” which, among other pollutants, included nonylphenol (NP) and octylphenol (OP) as environmental endocrine disruptors. This decision highlights the growing concern over the harmful effects of alkylphenol ethoxylates (APEOs) like NP and OP on the environment and human health. APEOs, particularly nonylphenol ethoxylates (NPEOs), make up 80-85% of the widely used non-ionic surfactants. 

In response to these concerns, Fatty Alcohol Polyoxyethylene Ether, primarily AEO-9 has emerged as an environmentally friendly and non-toxic alternative to traditional NP/OP surfactants, offering promising solutions for industries such as personal care, detergents, and agriculture.

The Problem with NP/OP Surfactants

Harmful effects on the environment

NP/OP surfactants are known to be toxic to aquatic life, causing hormonal imbalances and reproductive issues in fish and other aquatic organisms. Their persistence in the environment also leads to bioaccumulation in the food chain.

Health risks for humans

Exposure to NP/OP surfactants has been linked to endocrine disruption, which can result in developmental, reproductive, and neurological disorders in humans.

Difficulty in biodegradation

NP/OP surfactants are not easily biodegradable, leading to their accumulation in water bodies and soil, causing long-term environmental damage.

Problems with wastewater treatment

NP/OP surfactants can interfere with wastewater treatment processes, reducing their effectiveness and causing issues in the treatment of water.

What is Fatty Alcohol Polyoxyethylene Ether?

Fatty Alcohol Polyoxyethylene Ether (FAPE) is a type of non-ionic surfactant that is widely used in various industries, including personal care, household, and industrial applications. FAPE is produced by ethoxylating fatty alcohols, which involves adding ethylene oxide molecules to fatty alcohols to form a chain of oxyethylene units. The number of oxyethylene units added to the fatty alcohol chain during the ethoxylation process determines the properties of the resulting FAPE surfactant.

FAPE is typically derived from natural sources such as coconut or palm kernel oil, and it is biodegradable and non-toxic, making it an environmentally friendly alternative to some other surfactants. However, it is important to note that FAPE can still have negative environmental impacts if it is not used and disposed of properly.

The properties of FAPE can vary depending on the number of oxyethylene units in the molecule. Generally, as the number of oxyethylene units in the FAPE molecule increases, the hydrophilic properties of the surfactant increase as well. This means that FAPE molecules with a higher number of oxyethylene units are more soluble in water and have better emulsifying, dispersing, and wetting properties. The hydrophilic-lipophilic balance (HLB) of the FAPE molecule also increases with an increasing number of oxyethylene units.

The names AEO-2, AEO-3, AEO-7, AEO-9, etc. are commonly used in the chemical industry to indicate the number of oxyethylene units in the FAPE molecule. The specific AEO name used can help determine the most suitable application for the surfactant based on its physical and chemical properties. Among all the variants, AEO-2 and AEO-9 are most used in the home care and personal care industries. AEO-2 is mainly used as the main raw material for synthesizing Sodium Lrureth Sulfate(SLES) and AEO-9 is a widely used cleansing and emulsifying agent in various cleaning products.

In summary, FAPE is a versatile and environmentally friendly non-ionic surfactant that is widely used in various industries. Its properties can be tailored by adjusting the number of oxyethylene units in the molecule, making it a highly customizable and effective ingredient in many formulations.

Applications of AEO-7 and AEO-9

Detergents and cleaning products

AEO-7 and AEO-9 are becoming more and more utilized in household and industrial cleaning products, including laundry detergents, dishwashing liquids, and all-purpose cleaners, as they offer enhanced cleaning performance and are environmentally friendly.
