Unilever sank 5% after Morgan Stanley cut its recommendation to "underweight". France's L'Oreal, the world's largest cosmetics group, tumbled 4.8% after Deutsche Bank lowered its rating to "sell", citing mounting pressure on margins from rising commodity prices and risks of a slowdown in consumer spending.
At 1255 GMT, the FTSEurofirst 300 index of top European shares was down 0.5% to 1 429.15, after falling to as low as 1 420.90 - retreating for the sixth time in eight sessions.
After posting a thin 1.6% gain in 2007, its worst annual performance since 2002, the index has already lost 5.1% in 2008, hammered by mounting worries over the prospect of a US recession.
"The market is in the process of pricing in a US recession, turning into bear mode, with more forecast downgrades looming," said Jean-Luc Buchalet, strategist at FactSet in Paris.
"Defensive stocks have been showing some resilience, such as telecoms and pharmaceuticals, while all the other sectors are just sinking," he said.
