Silicates in liquids
I don't see any reason why a liquid laundry detergent couldn't have silicates. However it may be that they are not needed in most liquid detergent formulations.
If the label lists "washer protection agents" or similar ingredient, then that means the product probably has silicates in it. However I note that in various ingredient lists (see link below), silicates seem to be associated with the presence of sodium carbonate (washing soda). My conclusion is that sodium carbonate is the main culprit in corrosion of washer parts, and the silicates are added to counter this corrosion.
Liquids usually have sodium citrate added as a water softener instead of sodium carbonate. I'm guessing that sodium citrate either doesn't attack washer parts like sodium carbonate does, and/or it has some built-in protection against such corrosion to begin with.
