Very Sensitive – I have used this product with each of my babies (3) and love it. I have even given it as a gift and whilst an unusual choice as a baby gift the new mother always comments on their satisfaction. I love the smell and as it is a liquid you don't need to use much more than a table spoon in your front loader for excellent results. Whilst I bought the product with the intention to use it only for washing baby clothes I do find myself washing other family members clothes too but it works a treat at removing stains. I have recently started using it for my son who has severe dermatitis and it seems the change in laundry detergent is making a HUGE difference. Liquid, smell, effective. The price - but as I said you don't need to use too much to get results. I wish it came in a larger bottle too.
