Soap and personal care products giant PZ Cussons (LON:PZC) warned that trading has worsened since its half year and profits will miss annual targets.
For the full year to May, profits will be £80mln-£85mln, down from £103.5mln a year ago.

Problems are again centred on the UK and Nigeria, said the Imperial Leather, St Tropez and Carex brands owner.
UK sales of established bathing and washing products have fallen as consumer confidence has weakened. New products have sold well but not by enough to make up for the shortfall.
Cost inflation, meanwhile, has affected the Nigerian market, Cussons added, which has affected buying levels and the normal second half seasonal uplift has not occurred.
Intense competition in milk has also led to lower volumes, prices and margins.
Cussons is reviewing the Nigerian milk business as one of a number of initiatives to stabilise trading.
This will also include less packaging to reduce costs, a focus on fewer larger projects and another round of cost cuts to reduce overheads.
