What is nonylphenol used for?
NPs/NPEs, which are produced in large volumes, are used for industrial processes and in consumer laundry detergents, personal hygiene, automotive, latex paints, and lawn care products.
Is nonylphenol a phenol?
Nonylphenol is a derivative of phenol which has a nine carbon tail attached to a phenol molecule. The chemical formula of this compound is C15H24O. Nonylphenol falls under the category of alkylphenols. However, the structure of nonylphenol can vary slightly.
Is nonylphenol toxic?
Nonylphenol is a toxic xenobiotic compound classified as an endocrine disrupter capable of interfering with the hormonal system of numerous organisms. It originates principally from the degradation of nonylphenol ethoxylates which are widely used as industrial surfactants.
Is nonylphenol ethoxylate harmful to humans?
Potential health effects include: Extreme aquatic toxicity. Skin and eye irritation. Reproductive harm. Birth defects.
Where is nonylphenol found?
In sewage treatment plants, nonylphenol ethoxylate degrades into nonylphenol, which is found in river water and sediments as well as soil and groundwater.
What is nonylphenol polyethylene glycol ether?
Nonoxynols also known as nonaethylene glycol or polyethylene glycol nonyl phenyl ether are mixtures of nonionic surfactants used as detergents, emulsifiers, wetting agents or defoaming agents.
Is nonylphenol ethoxylate flammable?
Combustible. Extinguish with dry chemicals, foam, or carbon dioxide. Water may be ineffective on fire. Cool exposed containers with water.
What is alkylphenol ethoxylate?
Alkylphenol ethoxylates are nonionic surfactants, consisting of branched-chain alkylphenols, which have been reacted with ethylene oxide, pro-ducing an ethoxylate chain. The main alkylphenols used are octyl- and nonylphenol. The octyl and nonyl groups are made from diisobutylene and tripropylene, respectively.
Is BHT an alkylphenol?
2,6-di-tert-butyl-p-cresol (butylated hydroxytoluene (BHT)) belongs to the broad group of alkyl phenols and as alkyl phenol ethoxylates BHT is on the Danish EPA “List of Undesirable Substances” latest updated in 2009.
What is milk NPE?
Nonylphenol exthoxylates (NPEs) are nonionic surfactants produced in large volumes and used in industrial processes, consumer laundry detergents, personal hygiene, automotive, latex paints and lawn care products. NPE residues likely surface in dairy production through the cleaning solutions used in the facility.
What is APEO surfactant?
Alkylphenol ethoxylates (APEO) are a family of synthetic organic chemicals being used for many industries for their surfactant properties. Among all the alkylphenol ethoxylates, nonylphenol ethoxylates (NPEO) are the most widely used in industry (production of plastics, paints, inks, adhesives.).
How does BHT prevent oxidation?
Synthetic chemicals such as BHA, BHT, and TBHQ are primary antioxidants that interrupt the free-radical chain of oxidative reactions by contributing hydrogen from the phenolic hydroxyl groups, themselves forming stable free radicals which do not initiate or propagate further oxidation of lipids.
What is BHT used for?
BHT (butylated hydroxytoluene) is a lab-made chemical that is added to foods as a preservative. People also use it as medicine. BHT is used to treat genital herpes and acquired immunodeficiency syndrome (AIDS).
What is the APEO test?
Alkylphenol ethoxylates (APEO) is the term used to describe the group of organic substances of which NPEO is one. These are mainly used as washing and cleaning agents (i.e. surfactants) and are used for textile and leather processing.
