The boost in revenues came as a surprise following last month's warning that revenues might be down by between 1% and 2%.
Pre-tax profits were also healthily up, rising 62% to £593m on turnover that was down slightly, falling 1% to £7.9bn.
Among other brands performing well were Dove soap and shampoo, which did well for Unilever in Japan, North America and Mexico, while in Europe sales of Dove surged by 60%.
The strong performance will be seen as vindication of Unilever's strategy of disposing of non-core brands. The group has implemented a growth strategy that has involved streamlining its portfolio down to 400 brands.
Unilever also said it expected its leading brands to generate 90% of sales by the year end, up from 84% currently.
In a statement, the company said: "We have made a sound start to the year. Continuing expansion in underlying operating margin reflects our determination to grow our business profitably."
