The well-dressed fashionable man dictates the rules of society. And, his supreme power comes from the use of superior agents for his care. These are his shampoo, toothpaste, and bath soap. The common thing about all these products is the way they foam. This happens due to the foam booster ingredients they add to the product. Foam boosters are zwitterionic.
Two-Natured Action
To understand the action, one must know how the foam booster ingredients such as zwitterion work. The zwitterion has two functional groups, one with a positive charge and the other negatively charged. In an amino acid, the basic group H2N gets linked to the carbon atom (valency 4) which is then linked to three other atoms or atomic groups. These include a hydrogen atom, an amine group, and an acidic group COOH.
Breaking the Surface Tension
The intermolecular forces between the surfactant and water are low. This results in lowering the surface tension making it easy for the detergent to remove the dirt. The action of surfactants in sunscreen lotions are different. In the formulation of sunscreen lotion, the main action is to block the harmful rays of the sun. There is no cleaning action needed. The sun protection ingredients are either oil in water or water in oil emulsions.
Observe Safety Always
While preparing the formulation of sunscreen lotion one should make sure the ingredients are safe. Users may inhale the vapours of the sunscreen or even ingest the lotion applied to the lips. If they contain harmful compounds, they could cause damage to the internal organs.
Active Ingredients in Sunscreen Creams
Chemical UV filters are the active ingredients in sunscreen lotions. The other ingredients include lubricants, thickening, and emulsifying agents, and perfume. Preservatives, colour, and absorbing agents like zinc oxide are present. The particle size will determine the completeness of dispersion.
