Ship liquid concentrate and reconstitute with tap water at the point of use
#00020
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.
#00026Concentrate formats need reformulation matching the performance of conventional products
Selling concentrate assumes it reconstitutes into the same product at home. That needs real reformulation: predictable dilution across varied tap water, dry-state shelf stability, sensory parity with conventional products, and a preservative that works once water is added.
