Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

Petrolatum is more commonly known as petroleum jelly. It is created by mixing waxes and mineral oils.

This ingredient is effective at reducing water loss by 99%. This is because it is an occlusive. Occlusives create a hydrophobic barrier on the skin to prevent evaporation. This property makes it great for hydrating dry skin.

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
