I have found an excellent biodegradable laundry product that is non allergenic and inexpensive. It is called Orvus. It comes in paste form and you only need a tablespoon per wash load.
It can be found in your local feed store for about $27 for 120 OZ ( 7.5 lb).
DESCRIPTION: Orvus is a soft solid when cool. When it becomes warm, it melts into an amber liquid. It gives equally satisfactory results in either form. When soft; stir before using.
INGREDIENTS: sodium lauryl sulfate, lauryl alcohol, sodium sulfate, water. NO phosphate. Biodegradable surfactants. USES: Efective in a wide range of cleaning tasks, such as cleaning rugs, upholstery, hand washing delicate fabrics, and washing livestock.
