The UK authorities have submitted their application to CHA for a restriction under REACH on the use of the cosmetic ingredients D4 (octamethylcyclotetrasiloxane) and D5 (decamethylcyclopentasiloxane) in wash-off personal care products. The proposal asks that an upper limit of 0.1% applies to each of these.
These can be determined analytically by gas chromatography-mass spectrometry (GC-MS). A further siloxane in this family, D6 (dodecamethylcyclopentasiloxane), is frequently found in mixtures with D4 and D5, but is not included in the scope of this restriction application.
