APEO & NPEO Testing

Alkylphenol ethoxylates (APEO)Testing

Alkylphenol ethoxylates are usually used as a wetting agent in textile processing. EU REACH Regulation (EC) No 1907/2006 limit nonylphenol (NP) and nonylphenol polyoxyethylene ether (NPEO) emissions. For many years, the NPEO been used as detergents, emulsifiers, wetting agents and dispersants; NP is used as a synthesis NPEO the media. NPEO and NP are highly toxic to aquatic life , water pollutants. They can destroy aquatic hormonal regulation system, resulting in the feminization effect. Widespread concern alkylphenol ethoxylates, octylphenol (OP) and octylphenol poly (ethylene oxide) ether ( OPEO ) .

Nonyl Phenol Ethoxylates

Although theUShas not banned the use of detergents based on nonyl phenol ethoxylates (NPEO) and other similar "endocrine disrupting chemicals,” the European Union has, and many brand name leather product manufacturers and retailers have adopted this ban as part of their own specifications.

Using Electrospray Mass Spectroscopy, we are able to determine whether leather contains NPEO, and provide the certification that you need to supply your customers.

A draft Commission Regulation to amend Annex XVII to REACH Regulation (EC) No 1907/2006 as regards nonylphenol ethoxylates (NPE) was published. According to the draft Regulation, the new entry46ais proposed to be added. Nonylphenol ethoxylates, (C2H4O)nC15H24O, shall not be placed on the market from 60 months after the date of entry into force in textile articles which can reasonably be expected to be washed in water during their normal life cycle, in concentrations equal to or greater than 0.01% by weight of the textile article or each part of the textile article.

This shall not apply to the placing on the market of second-hand textile articles or to new textile articles produced exclusively from recycled textiles.

Note:“Textile article”means any unfinished, semi-finished or finished product which is composed of at least 80% textile fibres by weight, or any other product that contains a part which is composed of at least 80% textile fibres by weight.

1. APEO-related knowledge

APEO includes Nonylphenol Ethoxylates (NPEO) 80-85%, Octylphenol Ethoxylates (OPEO) accounted for more than 15%, 12 alkyl phenol polyoxyethylene ether (DPEO) and nonylphenol polyoxyethylene ether (DNPEO) each 1%.World alkyl phenol ethoxylate (APEO) annual consumption of 880 million pounds, which more than 80% for nonylphenol ethoxylates (NPEO).Because the APEO potential damage to the environment has been extensive research and validation.Some European countries since 1976 have developed laws and regulations restricting the production and use of APEO.

2. Ecological safety of APEO

APEO to ecological effects can be summarized into the following four areas: toxicity, biodegradation, environmental hormones, produce harmful by-products in the production process. a.Toxicity of NPEO9-10: LD50=1600mg/Kg;ECO50 for 42mg/L in the water flea;Algae ECO50 to 50mg/L, indicating that NPEO toxicity to mammals and aquatic organisms when cancer, while similar to other non-ionic surfactant. b.Biological degradability: slow degradation of APEO, the biodegradation rate of 0% per cent. c.Environmental hormones: APEO in estradiol-like effect, chemicals that can harm human hormone secretion of normal, says "female effect" and distortion.

3. APEO products exist in a

Wetting agent, wetting agent, penetrant penetration agent, scouring agent, scouring agent b.Emulsion paste, glue, adhesives, coating film, amino silicone oil, waterproofing agents c.D detergent detergent, SOAP lotion.Dispersing agent for dye using leveling agent
