There are certain products such a toothpaste and gums that still contain chlorophyll and are in use presently. The chlorophyll used is in its synthetic form Chlorophyllin - a water-soluble salt obtained by alkaline hydrolysis of chlorophyll with replacement of the magnesium by copper and methyl and phytyl ester groups by sodium and potassium.
Water-soluble chlorophyll derivatives are currently used in deodorants, toothpaste, breath mints, mouthwash, detergents and medicine.

The advent of variations in additives and flavorings in products such as toothpaste and gum, made the decline of using chlorophyll ( Chlorophyllin) as an additive becoming not so popular compared during the 20th century.

Because chlorophyll is water soluble and gets lost upon dehydration. What is left for making toothpaste, gel, capsule coating, lotions, shampoos and the like are substances we call emuilsifiers.
