Beco's Natural Undergarment Shampoo is made with coconut-based surfactants, tackling stains like period stains, body fluids, and sweat stains, all while leaving no residue and keeping fabrics soft. Delicate fabrics like lingerie and innerwear need pH-balanced care, not harsh detergents. Regular laundry liquids can cause skin irritation, fabric damage, and reduce elasticity. It's dermatologically tested to be safe for your skin, and free from phthalates, parabens, phosphates, bleach, and SLS, making it as gentle on you as it is on your delicates.
