Bath salts

It is said that these salts improve cleaning, enhance the enjoyment of bathing, and serve as a vehicle for cosmetic agents.

[2] Some bath salts contain glycerine so the product will act as an emollient, humectant, or lubricant.

In addition they commonly include coloring, fragrance, and/or other water-soluble, water-dispersible, and/or volatile ingredients for esthetic, cosmetic, or skin soothing purposes.

This principle of effervescing while releasing other ingredients is the same that has been used by tableted products for children to produce their own carbonated beverages.

Even though bath additives containing emollient are sometimes suggested for the treatment atopic dermatitis, their use does not provide any benefits for the symptoms.
