Answer

Explanation

Glycerol is added to shaving soap to prevent rapid drying while to enhance the leathering property of soap, a gum called rosin is added to them. It forms sodium rosinate which lathers well. Soap granules are dried miniature soap bubbles. Builders/fillers make the soap act more rapidly. Builder or filter (e.g. sodium tripolyphosphate) is added to detergent powder. Its main function is to act as water softener by removing `Mg^(2+)` and `Ca^(2+)` ions from hard water by forming stable soluble complexes.
