Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.

Butylene Glycol is a very popular synthetic alcohol. It helps the product to absorb deeper and faster. It is also a solvent for other ingredients. As for the skin benefits, it helps to attract water and helps to make the skin softer.
Polysorbate 20 doesn’t have any notable skin benefits but is used in cosmetics quite often. Manufacturers use it for formulation purposes. It improves the scent, texture, and feel of the product.
Sodium Hydroxide is used mostly for formulation purposes. It helps to hold the pH level of a product. It also works as a chemical exfoliator that removes dead cells. Usually concentration of this component is low in skin care products and it’s used mostly for adjusting pH.
Tetrasodium EDTA is a formulation component. It is a pH adjuster and chelate. It prevents other components from reacting with each other making the product live longer.
