Studies suggest that some products can exacerbate existing conditions and even trigger breathing problems in people who have never previously suffered from the illness.
If proven, the link could make some cases of the disease preventable, according to Dr Jan-Paul Zock, an expert in occupational asthma. Around five million people in Britain suffer from asthma.
Rates of the condition are thought to have doubled in the two decades to the mid 1990s, but plateaued since then.
A range of studies have shown a link between asthma and exposure to some cleaning products, Dr Zock, from the Centre for Research in Environmental Epidemiology in Barcelona, said.
