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.

Alcohol Denatured is a great bacteria killer. Manufacturers often put it inside products to increase their shelf life.

It’s one of the most harmful alcohols used in skincare. You should use it carefully, especially if you have dry skin. It removes oily barrier from the surface of your skin making it less protected and causing dryness. We advise you to pay attention to the position of this component in a formulation. If it stays below the 6th position it will hardly harm your skin. We also recommend testing the product first before application. If you feel a “cooling effect” it means the product contains a lot of alcohol and it's better to be careful with it.

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.

Unlike many other “Glycols”, it is not harmful and that's why it is used in many products. It was approved by US FDA and US EPA for usage.

Polysorbate 80 is a formulation component. It helps the components to mix better and makes the product feel smooth on the skin.
