Composition of Liquid Soap

1. Water: The primary solvent, making up the majority of the formula.
2. Surfactants: These are the cleaning agents that help to remove dirt and oil from the skin. Common surfactants include sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), although natural options may use milder alternatives like decyl glucoside or cocamidopropyl betaine.
3. Moisturizers: Ingredients such as glycerin, aloe vera, or oils (like coconut or olive oil) to keep the skin hydrated and prevent dryness.
4. Preservatives: To prevent microbial growth and extend the shelf life of the product. Examples include phenoxyethanol, parabens, or natural alternatives like vitamin E.
5. Fragrances: For a pleasant scent, either synthetic or natural essential oils.
6. Colorants: To give the soap an appealing color, though many natural liquid soaps avoid synthetic dyes
