Comments on Chemical Identity The notified chemical is never isolated, but is formed together with the butyl analogue, with the resulting mixture used in the formulation of brake and clutch fluids. The notifier has provided the composition of two representative brake fluids. One of these (named Shell Brake Fluid Dot 4) contains the notified chemical. The butyl ester analogue of the notified chemical is the subject of a separate new chemical notification (NA/657) and is also contained in Shell Brake Fluid Dot 4.
