Poly(oxy-1,2-ethanediyl), .alpha.-2-naphthalenyl-.omega.-hydroxy-, commonly known as Nonylphenol ethoxylate (NPE), is a nonionic surfactant that is widely used in various industrial and consumer products. It is a complex mixture of compounds resulting from the ethoxylation of nonylphenol, which is produced from the reaction of nonene and phenol. NPEs are known for their emulsifying, wetting, and detergent properties, making them suitable for use in applications such as textile processing, agrochemicals, and cleaning products.
Used in Textile Industry:
Poly(oxy-1,2-ethanediyl), .alpha.-2-naphthalenyl-.omega.-hydroxyis used as an emulsifier and wetting agent in the textile industry for processes such as dyeing, printing, and finishing. Its emulsifying properties help in the dispersion of dyes and other chemicals, ensuring even distribution and improved colorfastness of the fabric.
Used in Agrochemicals Industry:
In the agrochemicals industry, Poly(oxy-1,2-ethanediyl), .alpha.-2-naphthalenyl-.omega.-hydroxyis used as a surfactant in the formulation of pesticides and herbicides. It helps in the dispersion and adherence of these chemicals on plant surfaces, enhancing their effectiveness and reducing the amount of product needed.
Used in Cleaning Products Industry:
Poly(oxy-1,2-ethanediyl), .alpha.-2-naphthalenyl-.omega.-hydroxyis used as a detergent in various cleaning products, such as laundry detergents, dishwashing liquids, and all-purpose cleaners. Its wetting and emulsifying properties help in the removal of dirt, grease, and stains, making it an essential component in these formulations.
However, it is important to note that NPEs have been identified as persistent organic pollutants and are known to have toxic effects on aquatic organisms. This has led to restrictions in their use and a push towards finding more sustainable alternatives to minimize the environmental impact.

Check Digit Verification of cas no

The CAS Registry Mumber 35545-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,5,4 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35545-57:
(7*3)+(6*5)+(5*5)+(4*4)+(3*5)+(2*5)+(1*7)=124
124 % 10 = 4
So 35545-57-4 is a valid CAS Registry Number.
