The quantity of active substances used in antifouling products to prevent growth has increased by 150 per cent between 1999 and 2012. During these years between 8 and 27 per cent were used in consumer products. In 2012 the quantity of antifouling products sold to consumers was 48 tonnes. The quantity antifouling products sold to consumers has increased considerably the last two years. The cause of this big rise in sales is unclear.

It is mainly copper that is used to prevent growth. Normally copper oxide is used, but some other copper substances are used as well. There are some products that contain zinc pyrithione as the active ingredient, but the amount can not be shown for secrecy reasons. Tinorganic substances have not been used in approved antifouling products in Sweden since 2001.

There are also antifouling agents that prevent growth only by physical means, for example by giving a slippery surface. They do not contain active substances and are not included in these statistics.
