PBT assessment

PBT assessment: overall result

PBT status:

the substance is not PBT / vPvB

Justification:

Persistence assessment

Screening criteria

 

Screening test		Test results / Justification
Ready biodegradability test(s)		Resorcinol diphenyl phosphate was found to be readily biodegradable in a slightly modified closed bottle test (61% degradation in 28 days, see section 4.1.2).

The assessed substance is readily biodegradable indicating that the substance is not a P/vP.

Criteria based on Annex XIII of REACH

There are no appropriate half-life data available for drawing conclusions as to the P / vP properties of the assessed substance.

Conclusion of P / vP assessment

It is concluded that resorcinol diphenyl phosphate is 'Not P and not vP'.

Bioaccumulation assessment

Criteria based on Annex XIII of REACH

 

Criterion for non-B		Test results / Justification
BCF <= 2000 L/kg		The BCF was determined to be 969 L/kg (see section 4.3.1).

The available BCF data indicate that the assessed substance is not a B.

Conclusion of B / vB assessment

It is concluded that resorcinol diphenyl phosphate is 'Not B and not vB'.

Toxicity assessment

Criteria based on Annex XIII of REACH

 

Criterion for non-T		Test results / Justification
NOEC >= 0.01 mg/L for marine or freshwater organisms (long-term toxicity)		The lowest toxicity value was a NOEC of 0.021 mg/l in a 21-day Daphnia magna reproduction test (see section 7.1.1).
Substance is not classified as carcinogenic (category 1 or 2), mutagenic (category 1 or 2), or toxic for reproduction (category 1, 2 or 3)		Resorcinol diphenyl phosphate is not classified CMR category 1, 2 or 3 (R45, R46, R49, R60, R61, R62 or R63) according to Directive 67/548/EEC (see section 3 and sections 5.7 - 5.9).
No other evidence of chronic toxicity, as identified by the classifications: T, R48, or Xn, R48 according to Directive 67/548/EEC)		Resorcinol diphenyl phosphate is not classified with regard to chronic toxicity (R48) according to Directive 67/548/EEC (see section 3 and section 5.6).

The available information indicates that the assessed substance is not a T.

Conclusion of T assessment

It is concluded that resorcinol diphenyl phosphate is 'Not T'.
