HL Deb 13 March 2000 vol 610 c190WA
The Countess of Mar

asked Her Majesty's Government:

Further to the Written Answers by Baroness Hayman on 22 February (WA 28) and 28 February (WA 52), and the Written Answer by Earl Howe on 1 March 1993 (WA 31–32), in which other diazinonbased sheep dips epichlorohydrin was used as a stabiliser; and when it was removed from these formulations. [HL1306]

Baroness Hayman

Epichlorohydrin was used by the manufacturer of diazinon to stabilise this chemical, which was then incorporated as the active ingredient in various sheep dips by a number of different sheep dip manufacturers. Epichlorohydrin was withdrawn from the formulation of diazinon by the manufacturer in 1981. It was used by some individual sheep dip manufacturers subsequent to 1981 but records show that epichlorohydrin has not been used in any formulation of currently-authorised diazinon sheep dips since 1992. Records of products removed from the market subsequent to 1981 are incomplete and it is not possible to establish whether or when epichlorohydrin was withdrawn from those products.
