Position 1
Both products have the same component on this position.

#1Water

Origin: natural
Role: Solvent
EWG Rating [ 1 ]

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.

Position 2

#2Propanediol

Origin: chemical
Role: Solvent, Viscosity controlling agent
Moisturizing
Hair conditioning
EWG Rating [ 2 ]

Propanediol is a good solvent, emollient and humectant. It helps to moisturize the skin and prevent moisture loss. In haircare products, it conditions hair and improves absorption of the product.

Origin: chemical
Role: Antifoaming agent, Antimicrobial agent, Astringent, Masking, Solvent, Viscosity controlling agent
Antiseptic
Alcohols
EWG Rating [ 1 ]
Bad for dry skin
Bad for dry skin

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.

Good for dry skin

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.
