The use of enzymes in detergent formulations is now common in developed countries, with over half of all detergents presently available containing enzymes. In spite of the fact that the detergent industry is the largest single market for enzymes at 25 - 30% of total sales. details of the enzymes used and the ways in which they are used, have rarely been published.
Dirt comes in many forms and includes proteins, starches and lipids. In addition, clothes that have been starched must be freed of the starch. Using detergents in water at high temperatures and with vigorous mixing, it is possible to remove most types of dirt but the cost of heating the water is high and lengthy mixing or beating will shorten the life of clothing and other materials. The use of enzymes allows lower temperatures to be employed and shorter periods of agitation are needed, often after a preliminary period of soaking.

Answer:
The enzyme breaks down the oily stain, then surfactants in the detergent attach to the remnants of the stain to remove it from the clothing. Lipase can be used on the surface of materials to ensure easy removal of oil. It works by forming a fabric-lipase complex on the surface of the clothing that creates a barrier.
