Sources of Nonyl Phenol (NP) contamination in consumer products such as toys, shoes and packaging material = Organic Phosphites

 

1. Organic Phosphite is added 20% in PVC stabilizer as secondary antioxidant. Its main raw materials are nonyl phenol (NP) .and phenol.

 

2. Different types of Organic Phosphites and CAS No. can be found in the following table. 

 

Type of Organic Phosphite

CAS No. 

 

Tris (Nonylphenyl) Phosphite

26523-78-4

Diphenyl Phosphite

4712-55-4

Triphenyl Phosphite

101-02-0

Poly (dipropyleneglycol) Phenyl Phosphite

80584-86-7

Diphenyl Isodecyl Phosphite

26544-23-0

Phenyl Diisodecyl Phosphite

255550-98-5

Phenyl Neopentylene Glycol Phosphite

3057-08-7

Tetraphenyl dipropyleneglycol Diphosphite

80584-85-6

Diisooctyl Octylphenyl Phosphite

68133-13-1

Poly 4,4 Isopropylidenediphenol C12-15 Alcohol Phosphite

96152-48-6

 

3. According to REACH svhc list, there are 155 harmful chemicals in the list.

You will grasp the seriousness of the list when you notice that out of 70+ million known chemicals in planet earth, the most harmful 155 are included here.

Most in the svhc list are CMR, chemicals causing cancer, mutation and reproduction problems.

 

Among the 155 shvc list (updated June 2014), the following are related to NP and Phenol.

 

No. 57

Phenol phthalein

No. 65

4-(1,1,3,3- tetramethyl butyl) Phenol 

4-tert-octyl phenol

No. 91

Nonyl Phenol

No. 142

Nonyl Phenol ethoxylated

 

4. Steps to “detox” your supply chain:

 

4.1   Ask suppliers to provide material safety data sheet (MSDS), then check the CAS No. contains any banned substances such as heavy metals and CMR chemicals.

4.2   Ask suppliers to provide independent laboratory test report to show their raw materials do not contain banned substances.

       These reports should be updated very year by supplier.

4.3   Ask your stabilizer supplier to phase out Organic Phosphite in production.

4.4   Ask your suppliers to sign green production document to guarantee that they don’t manufacture and they don’t handle Organic Phosphites in production.

4.5   Choose a suppler with a lower test results.

4.6   Test your product and keep replacing toxic manufacturer by green manufacturer until your own product’s nonyl phenol (NP) content reaches “not detected” level.
