Also an extended period of time in the liquid, it may degrade the enzyme. Enzymes are proteins after all. When you get a strong base on your skin, it is essentially damaging the proteins in your skin.
Lipase is good for breaking down oily things. I never designed a detergent formulation but I assume that it helps with stains that aren't easily water-soluble. Upon contact with the lipase, it would break the oil molecules into smaller pieces and make it more water soluble. I think different proteases have different selectivity for different amide bonds if I remember correctly, so pick one that is generalist.
So to solve your problem, you could either make your enzyme detergent fresh every time you make a wash, or hold your breath and wear a pair of safety goggles.
Also, where will you get your protease and amylase?
