1) Lauroyl chloride (CAS 112-16-3): >=30 to <=70%
(hydrolysis product: lauric acid, CAS 143-07-7)

2) Tetradecanoyl choride (myristoyl chloride; CAS 112-64-1): >=10 to <=30%
(hydrolysis product: myristic acid, CAS 544-63-8)

3) Palmitoyl chloride (CAS 112-67-4): >=1 to <=20%
(hydrolysis product: palmitic acid, CAS 57-10-3)

4) Decanoyl chloride (CAS 112-13-0): >=1 to <=15%

Short-term toxicity to fish

Regarding the information requirements of REACH for this tonnage band, a study with fish is not required.

A weight of evidence approach was conducted based on available data of structurally similar substances. With high probability the substance is acutely not harmful to fish (96 -h LC50 > 100 mg/L).


Short-term toxicity to aquatic invertebrates

With high probability the substance is acutely not harmful to aquatic invertebrates (48-h EC50 > 100 mg/L; BASF SE, 2012, project no. 50E0399/11X282).


Toxicity to aquatic algae and cyanobacteria

The substance is acutely harmful to aquatic algae (72-h ErL50: >10 and < 100 mg/L; BASF SE, 2012, project no. 60E0399/11X281).
