Liquid personal-care products are mostly water, wasting transport capacity when shipped
#00017
Shampoo and liquid soap are mostly water, often 70 to 90 percent by weight. Shipping ready-to-use liquid moves large volumes of water already available at the tap, wasting transport capacity and fuel and forcing the bulky single-use bottle the water weight requires.
#00020Ship liquid concentrate and reconstitute with tap water at the point of use
Sell shampoo/soap as a concentrated liquid (or tablet/powder) that the customer dilutes with tap water at home. Removes most of the shipping weight and volume while keeping the product a liquid the customer already knows — preserving brand control over the final formula.
