Sodium Hyaluronate is an amazing component! It plays very important role in skin hydration process. It helps to maintain water balance and lower water loss. Scientists have found a direct dependence between the level of Sodium Hyaluronate in cells and skin aging. That's why this component is so much important. It must be in your routine if you want to have a healthy and fresh looking skin.

Some people think that Sodium Hyaluronate and Hyaluronic acid are different names of the same component, but it is not entirely correct. Hyaluronic acid is a different chemical but with similar effects. Actually, Sodium Hyaluronate is used in cosmetics much more often because it’s more stable and has much better resistance to oxidation.

It's very important for healthy skin. The lack of this vitamin can cause dryness, itching, and sun sensitivity.

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.

Position 5

#51,2-Hexanediol

Origin: chemical
Role: Solvent

1,2-Hexanediol can do a lot of good things for the formulation of the product. It’s an emollient, preservative, and humectant. It keeps skin hydrated and soft. It’s a good component for dry and dehydrated skin.

#5Pentylene Glycol

Origin: chemical
Role: Skin conditioning agent, Solvent
Moisturizing
Hair conditioning
EWG Rating [ 1 ]

Pentylene Glycol is a great replacement for Propylene Glycol. It has very similar characteristics but it’s derived from plants (usually from corn). Natural cosmetics lovers will find this component very useful. It enhances the moisturizing effect of cosmetic products, improves the efficiency of preservatives and it’s an effective emulsifier. It’s approved by ECOCERT and COSMOS so it’s considered to be 100% safe and can be used in vegan products.
