Can you use regular laundry detergent for hand washing?

It is not a good idea to use regular laundry detergent for hand washing on a regular basis. If it’s an emergency, you can use it, preferably on clothes that would normally be machine washable. Wool, silk, cashmere, and any other item that normally needs hand washing should normally be washed in a gentle soap mix or hand washing mix because the enzymes in normal detergent are too strong for such materials. Also consider the effect the machine detergent might have on your hands, as it can be quite drying. In most cases, you’d be better off choosing a mild dish-washing liquid over machine detergent when hand washing clothes.
