Nonylphenol (NP) is a non-ionic surfactant used mainly in the manufacture of cleaning products, such as detergents, and in the agrochemical industry as emulsifier. It is used to a lesser extent in pesticides as well as resins. It also has applications as a wetting, stabilizing, and dispersant agent.

Large amounts of nonylphenol from industry have been released into the environment since World War II. This substance can be absorbed by inhalation, through the skin or by ingestion. It interferes with metabolic processes in the body, affecting the rates of synthesis or breakdown of natural hormones. It contains a possible risk of damaging fertility and is harmful if swallowed.

This product is very toxic to fish and other aquatic organisms. It does not degrade easily, taking months or even longer to biodegrade from surface water or soil sediments.

In Europe the use of this product has been prohibited due to its adverse effects. In international markets, it is expected that its use will tend to disappear.

We at INTOchem present an excellent alternative: Ethoxylated Tridecyl Alcohols (TDA), which form the largest family of non-ionic surfactants and represent an excellent option as substitutes for nonyl phenol.

These surfactants are resistant to acids and bases. Consequently, they are suitable for the emulsification of fats and oils in a highly acidic or highly alkaline environment. Depending on their HLB values (Hydrophilic–lipophilic balance), these surfactants can form either oil-in-water (o/w) or water-in-oil (w/o) emulsions or improve wettability.

This non-ionic surfactant has an excellent environmental profile (high biodegradation), while enhancing the effectiveness and quality of the spray.

We can offer different alternatives of this product depending on the specific use. Please contact our sales representative for more information.
