Unilever's growth in the third quarter was hampered by poor weather in Europe and natural disasters in the Americas.
Paul Polman, chief executive, said conditions in developed markets remain challenging but the company is starting to see signs of improvement in some of its biggest emerging markets, including India and China.
Turnover fell by 1.6% in the third quarter, which included a currency impact of -5.1%.
Turnover increased 3.1% in the first nine months, including a currency impact of -0.6%.
Underlying sales growth in the third quarter was 2.6%, with prices up 2.4% and volume up 0.2%.
In the emerging markets, underlying sales growth was 6.3% with volume up 1.8%.
For the full year, the company expects underlying sales growth within the 3% to 5% range and an improvement in underlying operating margin of at least 100 basis points.
